Anything you need is as close as your keyboard. It's just a matter of your ability and how deep your pockets are.

I have a friend that runs 14.8 psi on a stock block all the time. He has split a few blocks adding small shots of N20 on top of his boosted combos, but they generally hold up fairly well. His best E.T. on 15psi (70mm Turbo) stock block with a 50 shot was a 10.01 @ 137 or 138 mph in a coupe body. This was happening on a stock 302 crank also. I don't know what kind of pistons he was running, but I know they weren't high dollar slugs by no means.

Yeah im not doing nitrous and the turbo is a 90mm he has other turbos that i can get but i thought that a bigger one could cause me problems down the road

You will have hella turbo lag with a 90mm on a small 302cid. If it is a street car, I wouldn't go over a 70mm. It will be plenty powerful with a 60mm, much less anything larger. A well tuned 60mm single set up will put you in the mid to low 11's around the low 120's in mph in the 1/4 mile. I guarantee it!

I listened to you and ended up taking that back he gave me two 60mm for 150 so ill make it work just got to build the flanges and get the rest of the stuff i dont have a need for the other one but o well he wants to get rid of the stuff

Twin 60's? They will split a stock block at 15psi of boost faster than a 20ton wood splitter through a piece of rotted yellow pine. Better check yourself before you wreck yourself. I wouldn't run anything over a single 70mm turbo @ 12-13psi on a stock block. Twin 60's will move close to the volume of air as one giant turbo. It's not only psi that you will need to worry about. Twin 60's will work, but I wouldn't push them past 8-10psi on a stock block.

minnow81469

No im only using one the other one is thrown in for free

minnow81469

Ill have that one for a spare in case anything happens or i might sell it who knows itll be nice for spare parts if ever needed

It's all good then. My friend has a single 60mm on a 6 speed fox right now pushing 15psi. It has ran very low 11's close to the 130mph mark with full interior and stereo system, jack and spare tire.
