im looking at the zzp stage 2 turbo kit
https://www.zzperformance.com/cobalt...=922&catid=143

ok so ive done a lot of reading but i still have some questions, some of which are probably stupid but here goes...

do i have to get anything/do anything different since its a 2.2 instead of a 2.4?
is a turbo manifold considered a "header"?
should i get a 3" catback or a 2.5"?
what internals do i need to upgrade? (i think its cams and rods...)

if you can answer any of these questions it would help a bunch

 

buddy of mines has a 2.2 on boost and hes making about 302 to the wheels on a stock motor and car has been running now for about 2 years with no problem

go with 3in exhaust if your going boost

 

damn dude! non-forged rods right?

bumpity

 

what psi is he running?

 

302 on the stock internals.......is he manual or auto aswell

 

yeah 300hp on a stock internaled 2.2 and stock clutch isn't happening

 

that was my thought exactly

 

even for an auto that is pushing the auto transmission threshold

 

so do you guys think ill have to upgrade the internals?

 

for 300whp... yes

 

after 250hp i'[d upgrade the internals

 

id be at about 250hp according to zzp, so maybe 225 whp

edit: upgrade what parts then? just rods?

 

yeah 250 crank cause its the rods that are gonna break first

 

any idea who carries em?

aight thanks =)

still need some questions answered. thanks in advance!

 

i would stick with a 2.5" catback since you wont be boosting a whole lot and your not making a ***** loud of power. a turbo exhaust manifold is what your thinking is a header. theres a few things needed differently. spankeys monkey did a 2.5 so check his build thread out. as far as internals rods and pistons are a must

 

i heard its >250hp you want a 2.5" so id be right on the border =/

 

would these rods work? theyre from the LSJ

I believe the LSJ wrist pin is larger than the 2.2's.

I have a stock set sitting around if you need some.

 

i thought so too =/
damn so im gonna have to pay like 1300 for rods and pistons. ghey

 

I dont see why you cant press something in to make them fit your wrist pin. Not sure how this would work. 1300? What pistons/rods you wanna go with? Eagle makes rods for your car I thought. Eagle is cheaper than many other companies.

 

stenguyen1 on here has around 260whp 2.2 s/cd

u should be fine around that area with a solid tune.

 

TTR has rods for like 900 and the pistons are about 400. ill look into those eagles though

yeah i was thinking about leaving the stock stuff but i dont want that fear that i will blow my motor and i just want that safety blanket since id be right at the border

 

400 for the pistons and 330 for the eagle rods but IDK how good eagle rods are.
