I just got my tax return so the fun begins I should be gettin my spec stage 3 plus clutch and motor mounts today installin it Monday at wrk I sold my nitrous set up yesterday I'm ordering supertech valve springs arp head studs zzp stage 2 turbo Kit with 60 lb injectors hopefully I'll have it all done within the nxt couple weeks prolly gonna start off with 12psi n work my wAy up hopin for 350-360 whp

 

yumm...

I've already spent the money on the Cobalt. My tax return is going to be used to finish my basement (complete with my pseudo man cave )

 

sounds great but i hope you are doing internals??

 

uhhhh why? It's not the 2.2, the 2.4's are good till about 400hp before you have to start doing internal work. Only issue was the valve springs when you start hitting mid 300's which he has covered

 

Ya I won't be doin a build just valve springs , cosmetic 3 layer head gasket and headstuds

 

your using make up for your head gasket?? lol its cometic...

 

Ha ya my bad

 

Jesus eff! how big are your tax returns??

 

3500$

 

that would be nice... the largest I have ever gotten back was $1200 :S

 

I had 20,000$ in tools to claim and my student loans and I only made 40k last year so I got alot of it back

 

Heat exchanger, header/downpipe, tsb for meth and a tune plus paying off the credit card was my tax return.

 

show me a 400whp 2.4 on stock internals

 

Its been known for awhile the 2.4's can handle to around there, theres a gm spec sheet floating around to back that up. Not to mentioned ZZP is pulling 356whp through an auto tranny 2.4 cobalt. Stock internals except 78lb valve springs with multiple track passes

 

HAHN has pushed 400hp+ on their dyno on a 2.4 solstice. Yes...it can be done. Granted, its on the verge of catastrophic disaster. But still..it took it.

 

i had 7000 in untaxed unemployment, got back 495 Fed and 137 state. Thank God im back to work!

 

thank you

 

My return will be going towards the ZZP Turbo kit. And yes, there will be a thread as soon as the fun begins.

 

im not doubting you im starting a build on my 2.2 and i just wouldnt want to see you blow it over a few pistons and rods

 

Bolded for emphasis...

 

the 2.4's powdered steel rods will not handle that stress for long. the cast pistons have been known to take abuse if you keep knock at bay and dont run too lean. the last spec sheet i saw, the rods were rated to 250hp

 

Last I looked on a spec sheet the le5 had forged rods forged crank cast pistons

 

Where did you read that? Everything I've seen shows that the LE5's internals are good to low-mid 300's and 8 psi or more. People push 360 hp through the Solstice/Sky LE5 with Hahn's S3 kit.

 

hahaha that made me laugh

 

i really doubt the powdered steel rods are rated that high. remember just because we can go that high doesnt mean its rated for safety at that high of a power level. lol. and i can assure you none of the pistons in these cars are meant to go past 300hp
