im really thinking bout buying this setup for my 04 cavalier. just want to push just 8 psi. but what i want to know. if there are any other people who have purchased this setup and what kind of engine management are you running? did you need a feflash? piggy back. any info would really help. thanks. should i also get a wideband??
ECOtec DOHC
you can use the stock fuel system setup to go further up, however the motor will bust if you go much beyond 10-12psi

I have nothing bad to say about that kit. It is an AWESOME SET-UP !!! Its been two months a little over 2000 miles.
The only extra mod that was needed is going to a 2003 Ecotec 5spd vin reflash for air/fuel ratio reasons.
I also have a Turbo XS (Ebay knock-off) BOV.....its loud !!!
Do some searchs on Hahn Stage II or Hahn Racecraft. Check out this too....

That's bull@!#$. It may be true with your RSM setup but I, along with many others, have run 15+ on our HRC St2 kits with nothing more than the FMU they provide.
Paul: HRC provides you with a FMU and 36# injectors with their St2 kit. This is a good way to get started but you will need someone with HP Tuners to change a few things in your ECU. These include your spark tables and PE mode settings. If you have any questions feel free to shoot me an email.

I dont have a hrc 2 kit, I have mine custom, but I am running 14 -15 psi with no more than bigger injectors, 2025 cartech fmu, and an afpr from summit. no fuel problems..

I have recently gotten a hold of this kit as well. Unfortunatly I wrecked my car last week & my insurance company is taking forever to come look @ it but I want to run like 10lbs of boost on my '04. I am running an '02 computer already so that's not a problem but I'm kinda lost as to how to tune the things Ryne mentioned above, I have no experience w/tuning or HP Tuners besided watching someone use it breifly. lol. I would have posted this in the tuning forum but the thread already exsisted with part of the info I need.
BTW Ryne you've been PM'ed.
It beats a Honda!
Hypsy didnt you blow your motor right? Ring land wasnt it, just like countless others with that kit
Did I blow mine up? No its got over 100k on it and running with another owner now
whats your point? You failed to make one
1989 Turbo Trans Am #82, 2007 Cobalt SS G85
i love mine. 8-10psi daily is a safe limit on the stock motor with the 16g fmu, inectors and pump with the kit. i ran 12 for awhile too.
anything above that and time WILL take its toll.. #2 or #3 ringlands seem to blow on the ecotec.
but its a risk you take when u turn the boost up. has nothing to do with company

No actually apparently only Boost from Hahn Racecraft Turbosystems can blow up motors, you can have same boost from equivalent setup and be just fine, when the motor knows the boost is from Hahn, it just blows up out of spite

That's because I actually made power with my kit you jackass. Your little supercharger from your joke of a RSM kit couldn't make enough power to break anything. Just because I actually used my money wisely and got the results you wish you could have gotten, and didn't get bent over without lube like you did, you get all pissy. Try making some power before you say HRC blew up my car.
I blew up my car by making 300+WHP.
How much power did your POS make?
I blew up my car by running 16PSI regularly.
How much boost did you get out of your kit again?
I blew up my car by making 250+ passes and driving 30K HARD miles on my kit.
How much abuse did yours see?
Until you can come up with another reason for bashing HRC than me having the kit and it costing a little bit of money, get a clue. Your car and kit sucked, mine didn't and doesn't.
BlackEco: I think your on to something there. LOL. That seems to be Matt's thinking.

I can name a few Ecotec's that ran 15+ psi on factory motors and did not blow up. Josh Solomom, Suncavi. Yes these were not Hahn kits, but boost is boost. Also these were run on FMU set up's. The key with the higher boost level is a good tune, plenty of fuel. I know both of these ran plenty of fuel.

Guys, lets stay on topic here, this thread is not about blowing up motors.
Alot of people use HPTuners to reflash their ECU with our kit, even though it is not necessary. HPT gives good versatility and if used right, is a great compliment to our turbosystem.
Our standard kit does come with an FMU. The kit is a bolt on and go, but as all cars are different, this is not always the case. Having a wideband is a good idea to optimize our setup and get those exact air/fuel ratios you want.

I was able to get my car running fine with the Hahn FMU, but I feel I got a lot more driveability after tweaking with a wideband and HPTuners. I think maybe if anything Hahn could offer custom config ECUs as an option along with their kits, they would do the PE tweaking to fix the known issues there as well as a few other things that would overall give better overall results with the kit. Not necessarily fuel but other parameters, of even if someone made a list of base tweaks to do with HPT on a boosted setup that would be a big help to a lot of newcomers, but learning it yourself doesn't hurt either.

If anyone comes to me and just wants the PE stuff and tables changed I only charge them the $100 to get the credits for their car. If I think about it I'll connect this computer to my car and save the tune to it and post it up so y'all can do it free. All I've done is change the PE values, 7500 redline, hi and low spark and fuel tables are copied, and it's set for 40# injectors. I think those are the biggest changes.

My POS looked better than anything you ever drove, your no different than the rustbucket driving hatch lover, you have 0 sense of style, this just in Blue doesnt match orange
I beat the @!#$ out of my car from the day I bought it and had well over 200 passes on it from 12 different tracks over the east half of the US, I was making over 200whp, and I started boosting it at a higher mileage than you ever had on your car even now, the reality is you busted a motor, I didnt, you blew it up because you were being stupid.
if you read my original post theres no reference to any brand kit, the ecotec will not survive long term over 15psi it doesnt matter what kit it is, sure you might be able to get away with it for 10-20k, but some ppl keep a car longer than that

Wow guys, lets stay on topic and quit bashing eachother. I am very happy with my Hahn kit and it was WELL worth the money. Yes if you want to run 15psi you need more fuel and building your engine for running that much boost long term is a good idea, as already stated. The Hahn kit comes ready to go out of the box at 8psi (give or take) and the best thing about it, you can build your engine and run more boost just by adding a boost controller and adding more fuel. Like Adam said HP tuners is a good investment to run with their system to tune it in even more, just as I have.
ok guys the reason most of the cars wre from hahn is because hahn is the only company that makes a KIT for the ecotec... and if you stay at the boost the recomend... theres no problems. obviously no motor will last at 15 +psi with an fmu.
dj had a megasquirt
sun cavi had the safc and like 650cc injectors.. not 32lb.
josh used a nitrous fuel solinoid for extra fuel
those are all huge difference from an fmu and injectors... obviously its common sence not to run 15+psi with just that and expect any motor to last.
matts car wasnt a pile.. you know that ryan. he got screwed by rsm.. not his fault. he made 200+whp on like 8-10psi?? thats pretty good for that SC.
again.
hrc is a badass kit for a stock motor if u dont get greedy.. and if u want to make more power. upgrade from the fmu.. its common sence.

Doesnt mean to hi-jack or change topic, but it will just be more information on the kit, so can anyone post numbers for a stock eco with this kit? like horsepower, torque, and quarter mile times?

Whats the limitations of the FMU? Is the limitation a less constant AFR? Mine does not vary much at all.
