Intercooler Piping
Monday, August 15, 2011 1:02 PM
I have an 03 Cavy that Im going to be turboing and I know that running intercooler piping is pretty much how you want to do it but I dont see alot of room on the passenger side of the motor to run it. Even on the driver side it seems that the brake booster is holding me up. Im realy not trying to run it under my motor and tranny because of geting it ripped off. But if I have to I will. So I was wondering if some of you that have turboed your 03-05 Cavy could possibly post up some pics of how you ran your piping.. Im want to run a T3 .57 or .60 trim and still worried bout clearance issues so any help on me having enough room would be great also.. Thanks to the ones that are helpfull..

Ive actually been curious to this myself...I mean there can only be so many ways to route this piping. I too am not a fan of having anything hang lower than my exhaust if at all possible, especially on a lowered vehicle!....piggy backing for the 411!

I will have my whole old kit for sale if another kid does not buy it once i get it all back.. Charge pipes from the turbo, all the way over the top along the motor mount, behind the passenger headlight, to the fmic, around the factory washer tank, you have to move the battery a little, and into the stock throttle body location. I can post pics when I get home if you want.

Yea man I would realy like that if you would.. And how much you trying to get out that kit?? I also been looking and the driver side is gonna be pretty easy as far as getting to the throttle body its just trying to figure out how to get the pipe from the turbo to the fmic.. But I know what your talking with going over the motor mount and behind the headlight Id just like to see some pics for more info..Thanks for the info and cant wait to hear and see more.. O yea what size turbo are you running if you dont mind me asking..

Ill look for the pics in a second. Im running a t3/t4 57 time,.63 a/r. I ran up to 16psi on it going for 20+ this year once I get it back. Ill post the best pics I can once I find them.

this worked with the stock washer tank and did work with the stock coolant tank.









Unfortunately I dont have any idea on a price yet due to any of the parts that have been used for the new part of the kit. The other kid was asking me on a price as well and I still dont have one for him either.

Man thats so effin nice!! Just what Im looking for..Those pics hit it rite on the nose. But yea I have a stageII p/p head,rods,pistons,eagle crank,all bearings,ballance shaft delete kit,62mm TB,and so on that hasnt been put on yet (parts are in my closet..lol) so Im trying to build me a kit (or get yours if I can) and have something that will get me to around the 400hp level. If I was to get a turbo like yours and other parts I need for my turbo kit (top brand not ebay junk) and get a great tune with HPT do you think that would get me there on like 15-18lbs of boost? One more thing whats that line running off the turbo going behind the brake fluid resovore going to?? But man all jokes aside thats a VERY nice setup and looks sweet!! Well thanks for the info and pics and cant wait to hear bak..

Sounds like you have a pretty hefty built motor. As long as you can get your tune right, you should be able to get close to what im getting.
You can see my mods in my mod list which get us close.

I have a nasty ported patriot stage 2 head, rods, stock comp but forged pistons, no balance shafts what so ever with custom delete kit., LS1 TB, Weakest parts will be trans.

Odds are you wont hit that on 15-18psi. At 16psi i made 323/323. So for you to hit 400 you will need probably 20ish psi.

The line running off of the turbo is my oil feed. thats getting changed this year as well. too low of oil pressure for my liking so it got moved. ill see what i can get for a price and talk to the other guy interested. I know he wanted either all of it or most of it but he is already turbo, But ill talk to him and see if I can get you rolling on boost first.



Re: Intercooler Piping
Monday, August 15, 2011 8:01 PM
Yea man that would be awesome Id love to at least have the fmic and piping..Yea my stageII head is a Patriot and the runners on both sides are ported like @!#$..lol.. It sure is a nasty head!! I have eagle rods,arp head studs and main bolts,weisco pistons (stock size) the MRZ balance shaft delete kit,all clevete bearings,eagle forged crankshaft (stock size) and so on but yea man when it gets built and boosted its gonna be sick!! Also I have a walbro 255lph fuel pump and Im still thinking about what size to go with my injectors..what size are you running or what size do you think I would need.. One more thing I know I have to tap my oil pan at its highest point for my oil return but where would I do my oil feed?? By the way Im digging your help and wouldnt mind talking to you more about my build and the turbo stuff..Thanks
Re: Intercooler Piping
Monday, August 15, 2011 9:19 PM
Your build sounds somewhat close to mine. what cams are you running as well as valve train? I have the stage 2 head with additional CNC porting on mine. Springs are PSI 1530ML's from a roush mustang. spring seats had to be bored out for them to fit. Passages drilled on the exhaust side so they spray oil on the valve train on the exhaust side as well.

Im running the racetronix pump which is pretty much the same thing except mine has a venturi line so you dont get fuel cut under 1/4 tank. My balance shaft kit is something todd miller did himself and got a limited chain and guide setup.

For injectors, I was close to maxed on my 42.5#ers. Im going with 750's now and MIGHT have got away with some 650's. But id rather have that little bit of overhead on mine.

Also, its a pain in the ass to do with the motor in, but you SHOULD really tap the girdle. Tapping the pan can work but when you floor it, the oil can back up and block the gravity drain. Id look into tapping the block, its the best way to do it. I did my first one in the pan which worked great. but this motor has it in the girdle and id never do it any other way. Hard to do in the car but it can be done.

I had my oil feed off the side of the block but I only saw 15psi or so and journal bearings need 55-65 so im going to be pulling -3an off the front of the block for oil feed. Should work out a lot better this time around.

Im also having the best tuner possible tune it Ryan Egleston Too bad he is in MO and not closer to you.

What clutch you running if you are 5spd? Also, what do you have for exhaust? blow off valve? wastegate?

If you can "clock" your turbo and send the pipe off the compressor housing down that's your best bet. I ran mine down, notched out some of the extra meat on the oil pan then around the frame. My front bumper is actually off the car atm so I can post pix @ when I get home
Re: Intercooler Piping
Tuesday, August 16, 2011 7:58 AM
Hey builtnboosted dont forget I dont have my motor built yet I have all the parts in my bedroom in the closet..lol..I have a set of JBP stageIII cams,adjustable cam gears,I have a set of BLE solid lifters ( heres the link if you want to look into a set http://www.cimotorsports.net/motor-sport-products/ble-solid-lifters-cavalier-ecotec.html ) I got my head bare and have supertech 78lb valvesprings,titanium retainers,bronze valve guids,supertech 1mm oversize valves,and factory rockers, I have a clutch masters stageII clutch kit, and exhaust I dont have yet..Im in the process of getting a turbo kit together so dont have a blow off valve or wastegate..Im going to be ordering the Turbo Tech Racing turbo mannifold this week (hopefully Fri). About the injectors would a set of 60lb injectors work on my setup? Also what brand are you running because Im having trouble finding ones that will fit my car. Also Im not sure where your talking about on the block as far as where to tap for oil feed and return..But hell yea man our builds are so damn close it aint funny..lol...

Re: Intercooler Piping
Tuesday, August 16, 2011 12:59 PM
I already ahve my pistons and now I have a question.They are stock compression and stock size.Is the 10.1 comp ratio be fine with getting up to the hp Im aiming at..Thanks man
Re: Intercooler Piping
Tuesday, August 16, 2011 1:42 PM
Oh I gotcha. I thought your motor was put together and in the car. Our motors are close but still gonna be totally different.

While im thinking of it, ill have my whole turbo kit and my whole old exhaust too that im selling. Package deal? I made 323/323 on it with room to go. I just wanted 3" and to add a cutout. You would have to mod it a little bit for the down pipe is all but it would fit.

As for injectors, you could do some RC injectors, 650's.

I know someone has pics of where the spot is on the back of the block. its by far the best place to do it.

For the pistons, i hope they fit the block you are rebuilding and you dont need oversized pistons. otherwise you will need bigger pistons. Im running stock compression as well and going to be in the same area as you are aiming for.



Re: Intercooler Piping
Tuesday, August 16, 2011 2:17 PM
how much for said kit? turbo/piping/complete? i have a 5spd 04 and 300+ would be my goal for a good dd

also, did you cut into your frame for the piping going back up into the passenger side wheel well? also, with your turbo setup, were you able to install the STB and clear that turbo?
one more thing do you have pix of how you relocated your battery? like brackets/etc...did you have to weld any mounts?

thats a beautiful setup..not too fancy but sweet looking and somewhat subtle..how I like a sleeper to look!

Re: Intercooler Piping
Tuesday, August 16, 2011 2:31 PM
No price yet. Seems to me there is a line forming now. Only hole I had to put in it was the one behind the passenger side headlight. Thats it. Driver side comes up where the stock intake pipe USED to be. I didnt have the strut tower bar on with mine but you easily could have. As for the battery relocate, im sure ill have the pieces in my trunk of the parts to move mine. I had to drill out my old battery tray to make it work is all.

My new setup will be even more sleepy except for the bright shiny intercooler up front. Otherwise sleeper as I can make it.



Re: Intercooler Piping
Tuesday, August 16, 2011 2:53 PM
Yea its not built yet..lol..but will be hopefully next year..And for the line forming I got 2nd dibbs..lol..Yea our motors will be totally differant because every one is differant even if built with same parts and a good tune..But I would really love to get that kit off of you if I can.As for my pistons I should have probably gone with a .20 or .40 oversize..Shaking my head..But if I need them I will just get them and sell my other ones.And yea when you find out where and or get some pics of where to tap the block that would be awesome..So the 650s you recomend Im gonna go ahead and get those because to be honest I was kinda lost on what to get and yours is already built and ours being kinda close thats what Im going to go with.. Oh yea did you check out those sollid lifters.I gotta question if something happens and I cant get your turbo kit would you be willing to help walk me threw with getting just the turbo set up like yours (minus the intercooler and piping and stuff) because thats exactly what I want and need..Thanks man and hope Im not asking to much..Its in your mods list to tho rite??

One favor I ask. more paragraphs please

Ill start to figure out what all I will have left over from my old kit and see if i can get prices and talk to that other guy to see what he wants to do.

Our motors will be close but mine has some little things done different as experiments. Who knows, depending how many miles your motor has on it, might be able to get away with just a hone and stock sized pistons.

Ill see if someone has those pics and sees this. Its basically a round flat part if you look at the back of your motor, its below the exhaust but above the oil pan. Hard to do in the car so its best to do with the motor pulled which sounds like you will have the chance.

I have stock lifters in mine and i dont see any advantage to those lifters. I have never seen lifter failure on our cars be an issue.

As for injectors, im running some lucas 750cc's I could have got away with 650's but RC's go up to 650 I think for high impedance.

As for helping with the kit. not a problem. Its just getting the parts and getting them welded is where the issue comes in.



Re: Intercooler Piping
Tuesday, August 16, 2011 5:39 PM
K I will make sure you can read it better.And I havnt heard of any lifter failier either I just figured I would get those just to have a little more support.

On that kit thats cool Im selling my ZZP heat exchanging system this weekend so if its soon just shoot me a pm and we will talk.The main thing Id like would be the front mount and all the piping.Oh yea I was going to go the s/c route but that wouldnt get me where I want to go..

Yea I hope so to man that Im ok when they hone it (102,000mi on motor) and dont need bigger pistons..lol..SO do those injectors fit rite in or do I have to use spacers,wireing harness??

I realy do appeciate you helping me with that..alot..I was looking into getting the Turbo Tech Racing manifold but the turbo flange faces downward at a 45 degree angle and by the looks of yours (what I want) it wont work. So what manni are you running..So I know that I will need a custom made down pipe for that turbo so what else on that would I have to get welded.

The setup your running is it external or internal wastegated..Im gonna guess External and if so I know that I would have to get the external wastegate flange welded onto the mannifold..rite.. Its just crazy because the way I told my brother-n-law I wanted my turbo setup to be and look like when I look at your pics I see mine..lmao..But hell yea man with your help and all this extra info I feel like Im getting sumthing accomplished.But Im also doing serches and reading alot on this forum to soak up all the info I can..

So what brand is that turbo your running and what type of front mount I wouldnt mind lookin those up getting some info on em..Thanks again BnB
Re: Intercooler Piping
Tuesday, August 16, 2011 6:44 PM
thats a lot easier to read. for sure. I dont see the need really for the lifters. Just my opinion.

I hope to have my car and all my stuff back within a few weeks. So until that happens, im stuck.

102K might need more than just a good hone not sure how long ago you bought pistons but id get it checked for sure and MIGHT have to bore it out some

for the injectors, Im not sure what happened with the connectors of mine. I bought adapters but its been so long ago i cant remember the connections of them. That you will have to look up for which connectors are on your car now and which one need. I want to say the RC650s are plug and play for our cars. Also ask around on if those will be big enough for you. they SHOULD be.... but im not 100% on sizing injectors.

I was running a manifold I got used off of someone, Ill still have it if you wanted to copy it, but its cracked pretty bad for sure. Im now running a Fetter manifold. Yes its external wastegate too. I still have my old tial 38mm wastegate too. Im reusing my tial blow off valve because i love how it sounds.

Im running a garrett t3/t4 57 trim, .63 a/r... REALISTICALLY I should go bigger but im using that as my limit to making more power than i need to.



Re: Intercooler Piping
Wednesday, August 17, 2011 8:52 AM
So what you do send your car off to get worked on?? When the time comes for me to get my motor built I will be stuck also because its my DD..Yea Im sure it will need to be and I should have researched about the honeing and boring before I bought those..But like some say sometimes you learn the hard way..lol

Yea Im going to look those injectors up and do some searching and see what I need if anything to get those RCs to work..Yea I wouldnt mind copying that mannifold you have because I can get a flange from crate engine depot (3/8" thick) and get it made like that..I dont want to realy copy your @!#$ its just that your setup is exactly what Ive wanted mine to look like. So you can post pics of that mannifold that you have or I will pay for you to ship it and that Tail wastegate (if its still good I will buy it).Also that wastegate would have to have the flange for it welded to the manni or the down pipe rite? And whats a cut out??

I searched and found some turboes like the one your using my question is do they all turn up top like so I can run my piping like that or would I have to clock it? And the Tial blow off valve you have I heard they are nice sounding..As long as I can get my turbo,mannifold and down pipe figured out and made (thats my biggest issue) I will be set because the fmic and piping will be pretty easy to run..
Re: Intercooler Piping
Wednesday, August 17, 2011 12:49 PM
Fetter, a guy on here, has my car doing a lot of the welding and paint work that I cant do. Otherwise I do as much as I safely and comfortably can.

What you COULD do, is find a locked up or junk eco thats the correct block and built it while you drive on the stock motor still. That seems like its your best option and safest. That way you can have the stock motor to fall back on if something happens. I will also say, dont expect everything to go perfect. Plan on the car having its issues and saying its your daily driver really makes that tough because if something does go wrong... you have to find a way to get around still.

As for the flange, im running a 1/2" in case the heat decides to warp it, its going to be a little harder to do.

You can copy my old setup all you want. Mine is already 100% different this year. It wont look anything like it does in those pics...

As for the manifold. Ill probably just ship it once i get it back. And the flange for the wastegate will go on the manifold itself. Wastegate is still good too. Just gotta get it once I get my car back.

A cutout is a manual or electric valve that makes it so when its close the exhaust comes out of the whole exhaust like normal. When you open the cutout, it makes it so the exhaust dumps out right where that cutout valve is. Mines going to be at the end of the downpipe for less back pressure.

you can clock the turbos any way that the housings will spin. as long as your center section is vertical for the drain and feed for oil.




Re: Intercooler Piping
Wednesday, August 17, 2011 2:37 PM
Yea my brother-n-law was telling me the same thing about getting another block and just send it out to get hot tanked,honed,bored (if need be) and just put it on a engine stand..Actually he hs been telling me to do this for a while now and seeing how you said I could do that and keep my oem motor for a spare if something goes wrong with my built one does make alotta scence.

I know that its not going to go perfect (trust me) its just that I want it all to go as smooth as possible.I sent TTR an email asking them if they could make me a mannifold that I needed so I will see what they say and I got ahold of RC Enganeering and I have my injectors figured out.. ..thanks to you for geeting me on the rite track with that.

Im not going to do my turbo,and mannifold just like yours because I want mine to be a little differant and put as much of my originality into it as I can. Not that I dont like yours because I do..I guess Im trying to say that I dont want it to look just like yours to a tee (i dont sound like a butt head do I)..

But you have deffanatly gave me some GREAT starting points and things that I can realy use that I couldnt figure out on my own..But yea when I go to get my turbo im going to make sure that It sits bak in there like yours does just for the simple fact I want to run my piping like you have yours so its not under my car (witch is dropped a bit) and getting ripped off by speed bumps or anything..lol..

I will keep in mind about the turbo having to be vertical for oil feed and drain..But yea theres not enough Js where Im at (hagerstown MD) and I wish it was because so sick of seeing hondas (not that I dislike them) it aint funny..>:o ..lmao..But when mine is built and running strong they will see just how a lil cavy can run!!!!
Re: Intercooler Piping
Wednesday, August 17, 2011 9:38 PM
Your best bet is to build the motor on the side. put it on a stand, take your time, do it right and slow. I kept my stock motor for the longest time thinking id go back to it if something went wrong. I still wish I had it just in case. I pulled it running perfect at 13psi for 2 years i think it was. sold it to a guy in chicago and he put it in his car that had a blow motor. not sure what happened after that with it. but honestly... id look for a spare block.

as for copying my setup. im not running that setup anymore... ill pm you the link to show you how my new setup is running so that if you go with what i had, it will still be different regardless of what mine looked like.

Injectors should be the RC 650's high impedance.
I BELIEVE these are their 750's which i dont think they were making when i was looking at injectors.
http://www.rceng.com/Saturated-Injector-SH4-0750-P63C6.aspx
These are the 650's
http://www.rceng.com/Saturated-Injector-SL4-0650-P32C6.aspx

those look to be about $98 each

these are what im running.... @ $70 each
http://fuelinjectorconnection.com/shop/index.php?_a=viewProd&productId=161

guy was GREAT to deal with. flow matched all mine. even swapped them out for free once i found out my other ones didnt fit and leaked really bad. he did a direct swap at no charge for mine.

ill get you that link and PM it to you.

Yea I found a reman block for $350 and my father-n-law has an engine stand that he said I could use as long as I need to.And yea I will defanately take my time and do it rite.I have printed out a sheet with the torque specs for the entire motor so I should be good on that and I know where everything goes its just when I go to put my timing kit on and cam gears is where I think Im going to hit a wall..

I realy dont know how to do the timing part but I know the #1 piston has to be top dead center and the marks on the cam gears should be at 10 and 2 i think..But when I get to that point Ill get some help on that..I will send you progress pics(pm) to keep you updated on my build soon as I start..I would post on here but realy dont want anyone disscuraging me just because alot of people on here seem to do that

Yea the guy I talked to yesterday at RC was such a nice guy and yea for all 4 injectors with the plugs(so I can splice into my harness) was like 380 or 390 sumthing ..but thats fine. So when Im ready to get my injectors should I ask them to flow match mine??

Hey I have sumthing else to talk about that I found on here last nite..Does every one have to run a restricter(what is this) when they run a high PSI turbo setup..I got to looking at the threads and come across that. I took it as if you tap the block for oil feed that the oil psi is so much that you have to run a restricter,what ever that is because they never realy explained it or what you do..Do you happen to know??
Re: Intercooler Piping

BuiltNBoosted..I'll give you $500 and all the respect in the world...Im also slightly crippled in my right ankle and my back..perhaps you could spare a disabled man and just 'hand over the kit'...have you not seen that movie 'Pay it Forward'? Hmm..think about it...

seriously though..if I were to boost..I'm thinking 300-330whp would be my goal..i guess i need to start taking notes from you guys lol
