Need a little help with a subject I am unfamiliar with - the snakepit. I've been keeping my eyes out for an '01 cobra vert for a few months now and have a few questions prior to pulling the trigger. My roush has ~425 crank hp, which is where I would at least like to be with the cobra. I understand the 01's have a forged crank, but should it stop there? If i were to slap a S/C on her, which I will do, would it be wise to beef up the rods and such?

For those who feel it's best to simply buy an 03/04 that has everything already taken care of, I prefer to add my own touch to the car.

It depends on how much power you want.8 psi is a good safe amount of boost on a stock bottom ens,and will usually be good for 425hp[or more] at the wheels.If you want more than that then it would be wise to build the bottom end.

compression is a little high on 01s to put much boost on.

I thought compression was 8.5??

your fine for the equal amount of hp your roush is making...a procharger will put you there and a kenny bell will be just as good...to match the roush is no problem...but anymore, then take the above advice and throw some customs in there

The roush maxes out at 400rwhp... what is a safe amount for the bottom end on the 4v motor? Also, would an 03/04 Eaton sc be possible? I know some intake customization would be needed

the block is good to 600, the crank is good to 800, the rods are the weak point, and i wouldnt give it anymore than about 500...im not sure about the swap though (although im sure most ppl will tell u get a whipple or kb because the "heaton" isnt worth the $$), but im sure either an 03 set of heads or porting could match things up[&:]

Actually it's 9.85.The 5.5psi Kenne Bell 2.1L kit is good for over 400rwhp on a '01 Cobra,and 5.5 psi won't hurt anything.

roush wont even compare to the cobra once you get the cobra upgraded a bit
