hello there i am just trying to figur this out i would like this info just so i know what , the max is the as well the best turbo for 550 , i have bin looking around and no one tells me what turbos thay are using or fuel set ups
for 450 , 550 .650,750,850 if any one can help me out it would be helpfull oh and best use for as street use as posible for most fields

 

Haha, sorry to say it, but if you have to ask, then you shouldn't be doing it

 

^x3..

 

qft.

 

well that is what i thought forum's are for to ask ? and posibly get a real anser 1 out of every 10 posts and i dont realy need to ask i can make work well the why i would like , but i am woundering what other set up are ,

850cfm holly carb set up , with injector plate , K51R Kai BB turbo set up 4400 rpm play time

 

It helps to know what cobalt trim you have.

LS/LT with the 2.2l
SS/NA with the 2.4l
SS/SC with the 2.0l

I hope you have ALOT of money to sink into this project if you hope to achieve 750hp. There is alot more to building a 750hp car then slapping a turbo on it capable of that kind of output.

Check out this build book for the 2.2l L61 - http://tunersource.gmblogs.com/Racer...L61-Build-Book

sleeved block , Arp studs head and mains
9.5:1 JE pistons

K51R Kai bb turbo
Carb /plat set up from old Quad 4 set ups 850 holly, 650 cc inj x 2

 

how about a 42r...

 

So is that what you have or what you plan on doing

 

Damn umm well you gotta a good list going.....BUT your going to need diferent pistons. You plan on getting that high with that compression ratio??/ HA NO! better think about a 8:1:0 diamond forged.

So trying to reach over 500hp with most of the power riding on boost is dumb to begin with. The max output of the 2.2l is just over 200whp, and thats with every internal upgrade you can do. so ur going to make up 500hp with forced injection. LOL your going to need a lot more done to the motor than just what u listed there budddddyyyyy. That would be like what ummmm around 40psi of boost. Come on man its a 2.2. lets be realistic sha'll we???

 

ditch the ecotec 4-banger, find a way to shove this in your engine pay. this way you only have 30hp to go.

actually if you read the ectotec build book, it tells you how to create a 1500hp 2.2. There are guys on this site already pushing over 225hp out of 2.2's and they arent close to complete. BTW... thats WITHOUT F/I. read up before you make dumb statements.

to the OP..... LOTS of money. Victory Red is gonna have the most powerful Cobalt and its gonna be in the 750hp range. Rear conversion, and well over 100k in work.

 

sounds to me like you just threw a bunch of parts on a list and think its gonna work. I can tell you right now that **** is gonna go boom with any high amount of boost and you are gonna have major issues making your desired power level without major boost.

yea i was thinkin about this the other day...he must be spending an ASS LOAD of money because he isn't doing the majority of the work here. It's not a project car, its a purpose built race car getting built by someone else. I'd bet on breaking the 100k mark pretty easily with labor/ R&D

forced induction? haha and the only way to get there is LOTS of boost with a four cylinder.

 

I would say garrett's site would a better answer for you. Those hp numbers u are looking for are unknown territory here. Im running the disco potatoe at 244wtq so thats all I could tell you.

 

doing the engine build on my car very shortly and upgrading the turbo. I want 500whp and the guy building my motor wants 750whp... so I"ll let you know how it turns out lol.

 

Yea, he is, but alot of it is subsidized by sponsors and company's wanting to be a part of that beast. But considering he said at one point he could go buy 2 corvettes for the money going into his cobalt should give an idea of the $$$$ going into that thing.

I still cant wait to see a Cobalt line up against a Vette and watch him wheelie off the line and PWN the vette

 

lol that'd be awesome

 

your gonna need a LOT of work man...youll need a new crankshaft, drill more oil passageways, get a new oil pan made for high G driving, drill the head studs deeper into the block, etc. i'd go with a 400hp build, and then see from there if you still want more power.....its near impossible to make a 700hp streetable 4 cyl...

 

you have to have A LOT of cash to do something like that. It is so illogical from a money standpoint. There are a lot of cars that could get the performance he is looking for for less than half the price, but i applaud him for doing it because it is gonna be uber unique when its done.

 

Not to mention a better interior.

 

You have no idea what my interior is getting done to it, so your statement has no merit or value.

 

A Big One!

 

I've said it before, to piece together the engine in the build book to push the 1450hp, it costs upwards of $30,000. Illogical? Not really when both he and I are able to say that we have some of the beastliest Ecotecs on the planet. I guarantee you that he's going to get some sort of magazine coverage for his efforts and to some, that's more important than anything is standing back at the end of the day and appreciating all that's been done. As for the 750hp ?, you're going to have a hell of a time trying to get everything set up.....there's SO much more that you need to consider.

What do you say Rod? Agree?

 

Yes Dan I agree. There is so much more to change, when you build an engine that can produce 750hp.
On top of that if you plan on racing that car on a sanctioned race track, there are many other details you need to take care of as well as having SFI approved components.
Having said that, Dan we will need to think about some how having a race when we are both done.

 

the list is what i have now , and yes i know i need aproved parts , and with this there is already most of a built car , and when tracked it has to much audio gear to reach the track times to have to many worrys , i could be wrong i will be traking it but only to realy see what the Numbers are , if thay are good i will be doing it more often , and then building a true track spec car if this one works out ,
thank you for your help

and with the money invested in the car already 10,000$ more could never hurt that does not even cover half the work in audio alone already done

But thank you and any help is very usfull im stating to love the cobalt
and goal is that she can do 13.5 with audio gear and full int

and so that i know what to do for my build after her's is done ,

And i have done some reading for a wile now and talk to some people 650hp is the magic #
