I'm going for 90psi now too if I can make 2000hp with off the shelf parts

 

And beat the GM Racing team that has corporate sponsorship

 

Darton sleeves suck too. Op needs to read for a year before he even touches an eco

 

Wow... And the useful information finally comes out... Perfect, now that I have a rough idea of some things to do and not do. This is great...

And if the supercharger is a restriction, what if you run 25 psi in the super. And 25 in the turbo... That way there no real excessive amount of boost trying to shove threw the supercharger.

Would it work, why or why not.. Will there be a restriction? If so explain.

And now after a brief explanation someone explained the math, ( I posted a link to it so my math is off which was good. Another great problem solved. ) and darton sleeves suck alright good enough...

I was debating on boring the engine rebuild center for sports was saying I should bore it. I just wanted to hone it out.

Ported head for the excessive amount of psi. I doubt the ecotec head could have 50 psi run threw it. Even with competition cams, valves, springs, retainers, rockers, etc.

And Holly crap stop bringing up a 2000 hp car I already stated I'm looking at 600 - 900 torque roughly on the same lines

And a turbo off a cobalt... Alright realistically I'll Rip the one that I rode off. It's a t3/t4.

 

all joking aside, you have A LOT of research to do

 

You should probably just buy a racing short block from zzp. Those can take the power your looking to make. I still dont think you understand how much power that actually is for a economy car. You should ride in a cobalt that makes 400whp and see what i mean.

 

Specify research. I know a stock 2.2 will handle a 75 shot nos. Also supercharger, and even a turbo at 10 psi. And no I don't need research I researched what I can and from this point the engine mods has always blanked me from day 1. I know the basics o need no questions asked forged equipment although the crank is 4340 billet steel I know. Forged rods, forges pistons.... But when you hit the head she's all a blank to me... Comp cams, and some kind of good working valves are probably a must, and from there you lose me. I know there such things as seals, springs, retainers, etc all the crap. Boring block o don't wanna do. I know that this kind of work also means a new rebuilt torque converter, possible swap with a 4t45e, either way tranny you need shift kit. Tranny cooler, torque converter, different clutch disc, kevlar instead of friction disc, better off to go with stage 4 or 5 axles. Highest grade steel, I wondered at times about carbon fiber then thought not even so I never researched it. Motor and tranny mounts cause you don't want that thing hoppen away on you when you tramp it. Bearing brakes. And suspension.. Good wide and lots of rubber tires for tractions,


I forgot lsd in there somewheres. Fuel pump, inline filter, 100lb injectors.... Ls1 or ls4 throttle body for more air. Each were cable driven each have an adapter plate to the supercharger, adjustable fuel pressure regulator which are pain in the ass to come by.......


Miss anything so tell me how much "MORE" research do you think I need....


Did I miss anuthing

 

this much more

 

Really? Pretty cool. I wouldn't mind the novelty if having one and that is more than enough power for me

 

Yup.

Little hint, boost does not equal same power, boost does not equal power. 26psi on a KO4 is less airflow than 24psi on a EFR 7163

 

See again that not very specific.. I know the parts I need to put in it. When it comes to tuning and boosting I'm lost.... My math was way off 64.7 psi apparently not 90. And other than that what am I missing seriously I must have a decent clue when I say **** like that... ... ... What the hell am I missing... Do you guys have a damn head guide laying around that I missed???

 

What's this Efr thing anyhow another type of turbo company?

 

Youre just spewing out parts but dont understand the specifics related to them, how they work, or what an ecotec really wants to make power. Read some peoples builds in the lsj performance section.

 

Go buy this kit from zzp 2.2/2.4L Turbo Kit - Turbo Parts & Kits

It will give you more than enough power.

If you have an 07 L61 replace pistons and rods, maybe swap to the LSJ head.

Stop talking in boost you need to calculate air flow, go buy a few books on building a custom turbo system if you're honestly interested in going that route, otherwise drop 6k into the turbo kit and engine.

 

You cant expect to just buy a bunch of parts, throw it together, and it works. You need to start with the fundamentals.

 

Go to the lsj forum and read the stickied threads. There are several threads including engine displacement and head design there

 

I kinda get the idea of how individual parts work except forced induction and heads. I'm fairly new one them... The old cobalt had a turbo in it when I bought it.

 

Hell even some of the L61 builds are decent enough to give him a start. He needs to just buy a pre-built kit for the turbo, and pay MrB or Mongo to build a L61 with forged internals.

 

Actually I've already seen both of their threads. And classified... And idk... And you know what guys I've completely gotten to over the point of the entire build the ultimate shitfire. What's an ultimate shitfire.. Buy a car for under 500. Put 2500 and see if she goes or blows. Plain and simple. This isn't my first build but it won't be my last either.

 

For 2500 you cant make a pretty fast cobalt. IF you know how

 

I have 500 in the car. 150 in the blower kit and 0 off turbo... Off my 07 cobalt lt... ( bought it had aftermarket turbo out on it) long story told short my light was green other light was red... I got t boned... Car got rode. So I bought a sunfire for 500 while waiting for insurance money. Got a super kit cheap off a buddy, and now this is where I stand. A stock sumfire. A lsj blower, and a t3t4 garret aftermarket turbo....

So I have 2350 left for parts any ideas?

 

Well you went in the wrong direction as the j body ecu sucks donkey dick.

Dont even bother turboing it unless you want to spend a year dialing in the tune. Supercharger alone is fine for that car though. Sell the turbo crap, put the supercharger on with a stage 2 pulley and i think youll be happy.

 

Alright then.

 

Actually never mind this post

 

K.. Okay just let me figure this out whats e85 I live in Canada a province that sells regular 87, plus 91, and supreme which is 96+ sometimes 97 and the v-power ( very few locations 105+ )
