Im about to wrap up the system. what is everyone doing for the IAT sensor? extending the wires and putting it in the intake off the turbo? also what plugs should i run with 9 psi and at what gap? i have read many different posts and no body seems to give a definite answer. i also called ATP and asked if my turbo needed an oil restrictor, the lady told me, well run it without one and if you see oil coming out, add one in.... well duh... but i would rather not find out that way if i can help it. its a t3/t4 57 trim with .63 a/r. i had a few more questions but cant think of them at the time. your help is appreciated, thanks a ton.

run a restrictor, I did...

iat - I left mine out in the way of wind....

and plugs? Suncavi posted the correct ones but I cannot remember which ones they are. I used srt4 plugs with no issue, let me see if I can dig up the number suncavi used

sweet thanks, and btw Ecotec if you didnt check my reg. any idea what our oil pressure is? thats what she said bases my turbo off of needing a restrictor, she said if i run one, i could starve the turbo of oil, if i dont, i could flood it and leak some til i get a restrictor, she sounded knowledgeable and gave me the # for the one i would use but im not sure. id like to try to get it worked out ahead of time and thanks for the plug numbers, thats one ive read is good but ive never got a decent answer. as for the IAT, the ONLY think im worried about is its true reading, im going to have to have the filter down by the firewall behind the motor on a 90 right off the turbo but maybe 6-12" down. would i be better to extend it to get TRUE IAT temps or just hide it in the engine bay and have it exposed to air?

not a problem... my oil pressure when I started my car jumped to 80 and slowly came down, once under operating temp it stayed around 20 and got till about 35 under full boost at high rpm. I have a very similiar style turbo and say run the restrictor... As far as the iat I ran it in the open air only to get a cooler reading.

the woman was saying if i was reading about 40 psi i should run a restrictor, you have a link to the one you have? they told me to run the one atp-022 from atp for mine. i just dont want to starve it of oil is all. and as for the IAT, i know thats why most do it but not sure if it will mess up my tune by having the false temp reading.

don't even bother entending the wires for the IAT, drill and tap the charge pipe and get a threaded Camaro IAT (part number and thread pitch listed in another thread, search for i in boost forum) thats way your getting the true IATs at the TB

that works to. Something I was going to do, but never got around too.

Oil restrictor is the same one I ran that she said

Yeah, Darkstar's method is the RIGHT way to do it for sure. I'll probably go that method this season as well. Last year I put the IAT in the tube leading to the compressor, behind the filter.

For Iat I used the MSD one just screws right in, Just gotta get an o2 nut.I think the part number is 8220 its on summitracing.com.i would run the restrictor to.As for plugs im using the srt4 plugs since i got them for free at work.

Camero IAT sensor, part number SU107 from WELLS.. I got it at Autozone. Run the wire to your charge pipe, about 6-8 inches away from your TB.

Not to sound rude but you're taking advice from the lady that answers the phone? Have you asked her if she's even qualified to give advice / technical information about the products? I doubt it.

Run a restrictor, it's cheap insurance. Your car sees over 40 psi at startup for a few mins that'll blow seals within a few weeks esp if they are weak. You install it after the pressure sender but before the line that heads to the turbo. You do not put it on the turbo end.

As for the IAT... Camaro IAT and a bung welded in is the only proper way to get an IAT reading, installed just before the TB just as the stock one is.

Good luck Vince, lemme know if you have any more Q's.
