I'm planning on picking up a used hahn stage 2 kit, but I just read one of the more recent posts on here about having to eliminate the washer fluid bottle. I'm wondering if there are any other things that need to be removed/replaced/decrease functionality? I read somewhere the foglights have to go... which is not something I want to happen - if this is the case... can the IC piping be run another route, because I want to keep as much of the functionality of the car as I can.
The kit comes with everything I'm going to need aside from HPTuners, Innovate Wideband and a new fuel pump. IIRC, the hahn kits come new with an inline, is that correct? If so, where can you buy it, or a similar one?
Thanks
Dave

you do lose the wiper solvent bottle, you do not lose the fog lights, you will have to trim a bit off the inner edge of the drivers side foglight indent in the bumper but you don't have to lose them. I still have both mine in my silver cav. it does come with an inline pump
Thanks man, so theres no other small things that people never really mention? The washer fluid bottle isnt a concern, I'll mount another one somewhere else.

little question for you guys!? why do you have to remove the washer fluid bottle???? i have a turbo setup (it not hahn it is custom) and i havent remove it!

Steven, how are your pipes routed, i am also looking to go turbo next year. custom setup? or Hahn?
Because Hahn designed the kit with the washer bottle removed. I have an idea for a way to get it back in there but I'm much to lazy in the winter to try it.

the only thing I do not like about the kit is how much fuel pressure it runs... but thats me...

how much over stock is the fuel pressure?, that setup uses the stock pump and an inline if i'm right.
what brand inline pump is it ?
It is an Accel inline pump with the kit, but MSD makes one just like it for less money. I would recommend a walbro in-tank while your at it. My stock pump is going out so I will be doing that soon.
Just to clarify, you only use the fog lights on the 00' - 02' cavaliers. I am working on the washer tank replacement.
Make that you will only have lost the fog lights if it was a 00' - 02' cavy. Brain fart on my part
Anyone know what the fuel pressure is like? I was planning on getting some bigger injectors anyway.
" To study and not think is a waste. To think and not study is dangerous. "
It's like 90-110PSI at 15PSI boost with the 32# injectors.

9 out of 10 busted ecotec motors on here agree that kit is the best way to blow up a motor

But weren't the engine internals stock? the ring lands aren't ment for that kind of boost/power.
x2^^^^^
plus its set from hahn at 8psi. ryne was at 15 for almost a year. i was at 12 for almost a year. mine blew after 2-3 weeks on around 18psi with NO tune. just a fmu. lol
airtonics is the only 1 that threw a rod but his was from the gm charger. and phills went from the powder coating place.

theres been more than a few on stock boost that have blown, as for the gm eco kit there hasnt been a one, Airtonics was a custom setup off a cobalt with smaller pulleys

No one that I know of has blown an Ecotec with the HRC while maintaining NOTHING BUT THE PRESET BOOST LEVEL. All of us have pushed it, after all that IS why we bought the kits.

i work at a Chevrolet dealership and looked on our service info for stock fuel pressure. it says only 50 - 60 psi.
so with the HRC system your fuel pressure is double, whats the reason? i realize the in-tank pump just becomes a pusher pump for the inline but why so much psi ?
does the HRC stage II system (in stock form) throw a check engine light for any reason? if so what codes?
haha yea 55psi is stock pressure and 65ish during WOT
The reason is they use injectors that are totally the wrong size for the power level (32lb is good for about 200whp on the ecotec) and in order to fuel enough they need to run the pressure through the roof in this day and age with HP tuners around, its totally stone age and its really not good for the injectors either, too much duty cycle from running too small an injector or running too much pressure to compensate will damage your injectors
Someone can install 42lb injectors and not hack up thier fuel rail nor worry about thier fuel pump worthless FMUs and FPRs and get better results with HP tuners
case and point the GM supercharger kit for the eco runs 370cc injectors at 10psi and its nothing more than an injector swap and a reflash but you can still use that with a turbo setup
Im not downing the kit, I love it and if for some reason I keep the cav its getting the stage 2 one, but Ill be damned if I run that piss poor excuse for fuel management or better yet just get the Port fueler setup
As far as codes you can prob expect the usual suspects but they can be avoided as long as your tuned right
P0130 - primary 02 sensor failure happens from ppl that get too big of balls and run leaded race gas
P0172 - Too Rich if your not tuned right
P0300 - Happens with ignition problems due to lean condition or improper plug gap
P0420 - Clogged Cat will happen over time being too rich
