well with some unfortunate luck my 346 went in the garbage long story short i cracked a sleve. and since my afr 225s are 1630s and a new ls6 block and forged crank costs 2500+ im going 408 and selling the t76 to get a pt88. the car is a street car my curent cam is 224 224 .609 .619 116lsa 114icl

it was on its way to making BIG power it was making 640 to the tires at only 13 pounds and only spining to 5200rpms when they shut it down to put some more timing in it.

so my question is stick with what i got or go with something bigger?

The exhaust housing on the PT88 is too small. That means that it will run out of breath early in the RPMs. If you are set on this route, then keep the cam small as your peak power will likely be low in the RPMs.

so should i go 370? would the cam be good for a 370?

Would be a better fit all around.

The 370 is even a little on the big side for the PT88 IMOP. I really need to upgrade the exhaust housing and turbine wheel in mine. You have to remember that this turbo is very popular in the competitive V6 world. I bought mine used off my buddy's grand national and many many supras run it as well.

the turbo will be fine for a 408 or 370 an will make tons of power under 20psi if u r trying to make 1400 1500hp u will need something bigger than the pt88

you could always build a smaller engine

Many will ask why (just because)

I am putting a old nmra dragradial 85mm turbo on it hoping to make 1000rwhp
