I wanna see whats the most somone is running for WHP
my goal with mine is 650WHP
i know with these numbers i am going tohave to go with a Stand alone computer set up witch is pricey!
going to run about 350 ish this summer then upgrade to a GT42R turbo with a GT28R to spool it.

if your gonna flame this then eep it to your self, this is strickly for the turboed 2007 2.2 cobalts

 

Lol, unless you have a fully built motor, you won't even be able to run half of that.

Crank starts to go at 500, rods and pistons at 250.

 

not to mention axels and fuel pumps and hell alot more upgrades then what it might be worth, id say do the garret kit, do some forged internals and call it at that, espically if its a daily driver and the 300hp range is more than enough for a lilitle speed

 

ooooo twin turbo?

 

Just make sure you don't lose any babies in that GT42R.

 

im a 2.2..........turbo will be an option for me when the warranty is up..........only thing is im and automatic.......anyone have an idea how much a decent turbo set up will cost?

 

ya im planning on building that 650hp balt myself im getting pretty close to having the motor completely built but this is what i have thus far



i still need:
GM Adjustable Cam Gears
GM Neutral Balance Shafts
GM Hardened Oil Pump Gears
Darton Sleeves
Fidanza Flywheel
Spec stage 3 clutch
Port Flow Port and Polish head
Clevite main and rod bearings

 

You taken it in yet to get estimates on how much the build will be? (labor)

 

i havent done that yet but i should get a good deal because ive gotten in good with the guys over at Jotech Motorsports so hopefully. but the head is gonna cost me around 1200-1400 to get ported and valves all installed.
problem im having right now is i need a spare 07 motor to keep from putting my car down

 

Dang, dude just rent a car, lol.

Probably a whole week it will be in the shop I would guess. Man, that's a pretty comprehensive build.

 

very comprehensive, but i want it done right you know.

 

wow. this is gonna be a hard build. you're pretty much gonna have to do whatever they did to get the drag ecotec to run the way it does...lol

keep this thread going and keep us posted i'd love to see it and good luck though, seriously.

 

Its not his thread.

I did notice something. You have turbo grind cams and a fully upgraded valvetrain + Neutral shafts. The powerband on the turbo cams is 2200-7000. You probably should have gone with Stage 3 cams instead and adjustable cam gears. You would make more use of that head work and valvetrain and neutral shafts(since you done need them until about 7500rpms).

 

subd for sweetness

 

I'm doing all that later, everything is getting boosted and tuned for 7 psi first.

Internals will come when I pay this off first, lol.

It's just a lot of money all at one time, I can't do it all up front like that.

Good luck, I'm waiting on some good numbers out of that thing.

 

holy crap what the hell happen to your balt

 

that is the first time ive heard of that info. definitely something i will look into. thanks

ya hopefully when its all said and done im aiming to be at somewhere between 18-24lbs of boost. thats insane yes,but itd be nice lol.
the motor should be done sometime in june

 

jotech is the ****. you're definitley in good hands with them

 

ya im friends with tony over there and he's been gettin my parts for me.
the one thing weve run into though is tryin to tune it. Kenny hasnt used LS2 edit before so there inlies the problem

 

I thought you were an 06? LS2 edit is for 07+

You might just have to get a trifecta tune.

 

Why?

 

no im an 07. i just bought the car in 06. i can see the confusion.

having to send off for a tune instead of some right then and there physically doing it isnt the same. theres way too many variables that come into play and when your spending as much money as i am im not taking any chances on blowing it up

 

I do see your point. I'm getting a canned tune from Trifecta remotely just so I can drive it, then I'm going to a trifecta dealer and getting it fine tuned.

 

Dude your wastegate is ginormous holy ****!I plan on doin the garrett kit and a mild build.cometic head gasket eagle rods and low comp pistons and call it a day

 

im actually going to buy LS2 edit myself here pretty soon so ill have it laying around the house. that way i can learn and change stuff as i go IF i ever need to
