so im gonna be deploying next month and a friend whos a GM tech is gonna be keeping my car (and a few others actually) and he'll be doing all the work on my car while im gone so i was thinking i want the maximum power i can push out of my car without blowing it up so heres my thoughts and you guys chime in with more ideas or even appearence **** you think i should do also to stand out that you thought of and wanted to see if anyone had the ***** to do it..cus let me tell you...I DO :

Hahns full turbo upgrade kit internals and all.
BOV
turbo timer (already installed)
meth kit or NO2 kit

what do you guys think?

 

I didn't think Hahn had the upgrade kit yet. I was just on their site like 2 days ago and it said it was still in development.

Don't forget to do a full 3in exhaust and DP too...and maybe bigger intercooler

 

I think you should save your cash on the deployment and come back to do the work yourself. Bigger turbo has my vote. The Synapse 2871R or 3071R swap would be where my money would go.

 

like i said he's a friend and a GM tech so he wont charge me like out the ass and plus i wont be able to do the work on my own anyways i dnt have those types of tools and he does.

my mods right now are:

Hahn IC Piping
Hahn CoolRam Intake
BPV Spring
Greddy Turbo Timer
B&M Shortend Short Throw Shifter (i had it cut to be even smaller and shorter throws)
3" Catless DP (which i want to swap out for a catted one)
Tuned
and a few other things i cant think of right now

Basically im add on to the limit already besides a bigger IC which i will get when i get the turbo

 

ah another good ol killeen boy weclome!!... please make sure your getting a good price on the labor.. dont blow the money iv seen so many guys run out of money or lose the car.. trust me iv been in the waco/killeen scene for 4-5 years

 

GT40r or bust

 

so bigger turbo and meth kit it is....i hope i dont blow my damn car up listening to you people

 

Go with a GT28 and a 75-100 shot of nitrous. We don't have the fuel system to support anything bigger than a GT28 properly yet.

 

but is that **** gonna lag and when i get the new turbo i plan on getten new fuel rails and all...im not gonna half ass it

 

Do you know anything about your car?

 

i know alot about my car...i will never say i know everything but i know alot about my car in particular..this is my first ecotec and my first cobalt tho.

 

Do some research before you start spending money on it.

 

then explain to me how a friend of a friend is running a 3071? the fuel system can support it fuel pressure adjustment is needed to make things easier

 

do you have it?

 

Not anywhere near the fuel availiable to support a 2871 with a 100 shot. That would likely be a disaster. I am almost out of fuel with my stock turbo. In fact my injector pulse width is about 5.8-5.9 mS at 6500 and up.

 

Wet shot.

I bet he is stuck around 400whp too...

Do I have what?

 

Extra injector needed I guess. 400 whp is about the most the stock fuel pump and injectors can handle so yes no matter how large the turbo most are right at 380-400 whp.

 

You do not need an extra injector with a wet shot. The stock low pressure fuel pump has worked out with over 500 whp so far. The high pressure pump/injectors/ecm is the limit so far. A wet shot gets around all of those limits as long as you don't spray over 20% or so of the total fuel used in the manifold. When you spray too much fuel in the manifold it does some weird things with the direct injection. So far, a 100 shot with around 500 total hp has shown to be the sweet spot.

 

strange that someone on solstice forums was putting down 600 whp with a 300 shot of nitrous .. yes i said it 300 shot is what they finally blew on

if theres all those issues right.. im mean it's not possible no way .. he must've divided by 0.... and marcus yes i'm agreeing with you lol

 

i dont wana blow my car..its my dd i just want more power i mean i do run it at the track so i want top performance...

so when i get this new turbo should i get new fuel rails and a pump and injectors and all? like what extras should i get with a kit to get MAX performance without blowing my car up or coming close to it

 

I know of the person you speak of, and you can run as big of a shot as you want. But, when you inject more than 20% or so of the total fuel used into the intake you get some weird results with direct injection.

Some type of fueling solution will be needed. No one has released anything yet for our engine however. What ever you do will need be be custom.


A good tuner, a wet shot, and brains.

 

That is insane to have as much nitrous HP as you have engine HP IMHO.

 

yea .. wasnt even a progressive shot

 

You want to talk about huge surge of nearly uncontrollable power that is nuts.

 

That would just be nuts....and it would hit like you have been rear ended by a freight train...be kind of scary when the surge hits in

The scariest thing ever for me was a Ysi powered Mustang I went for a ride in a few years ago which runs 8's on slicks..little under 1000hp in a 2800 pound car....truly scary as a passenger for the 2 seconds he would give it throttle at a time....now THAT was surge

But it gets to a point where it is way too much for the street...
