Im currently putting back together my 10:1 comp 408 ci roush stroker carb engine and looking to turbo on e85. I want to select a turbo and my build lists as follows...

Roush block (351w .030 over bore)
forged steel eagle 408ci stroker crank
Eagle forged H beam rods
Edlbrock Victor Jr port matched intake
Fully ported and polished trick flow twisted wedge heads. (and Im talking chambers done and mirror polish on exhaust and begining of intake runner. Short turn radius left slightly rough for atomization reasons)
Flat tappet cam .514 .545 lift and something like a 256/250 duration
main cap girdle
high volume oil pump
200,000 psi mainstuds ARP
900 dominator e85 tuned alky carb in a carb bonnet
MSD 6 AL ignition, coil, and distributor.

I've never turbo'ed something quite as hairy as I want to build here so Im looking for help/ suggestions.

 

How fast are you looking to go?

 

about a S480,, maybe a little bigger

 

I was thinking S480. I was told pt88 for as heavy of a build as I have but Im not trying to go 7 secs. Looking for mid to low 9s for a demonic street build.

 

I was planning on running a twin setup with 2 master power t61's .70 ind .86 hot. But one was destroyed on accident and I cant find a match for the one I have anywhere. So here I have a brand new turbo that's of no use to me.
