What is the biggest engine that can fit in replace of the 2.4L Ecotec. with fewest modification or is there a way to get my 2.4 to 300hp cause im shooting for +300

 

to my knowledge (limited as it is) there is CURRENTLY no way to get to 300. HOWEVER, time may solve that little problem with proper tuning for turbo's and other such upgrades.

 

you could fit a v6 in there?

 

That would be a major change, Chris.....cooling, a/c, brakes and booster would need to be relocated, etc. etc. This had been looked into. Just not practical for a everyday "street" car.

 

How 'bout an LS4? Probably have to fabricate a new power cradle, but it'd probably fit. Those are 303 HP stock.

Hahn Racecraft will probably have a turbo kit soon that'll pull close to that once they get the computer issues worked out.

 

easiest route may be using the 2.0 litre & turbo (juiced up).....

 

Agreed...

Or the Hahn people.

But, any way around it...well set up turbo, an engine swap to 2.0, or anything else...you'll spend about $5000+ for 300HP, if it is set up properly and done "cleanly".

 

throw something japanese under the hood...

 

go with injectors, intake, header, exhaust, tune, cams, and NOS :)

 

i have actually thought about putting a b series engine in one
