Have a sleeved 8.5-1 H22
Have a hookup on BW turbos...
Can't decide on a s363 or s366...
Really my question... both come with .88 a/r turbine housings. Is a .88 to big for a 5-600hp H? Would a 66/72 combo be better than a 63/68 combo with a .88 housing?

Ive read where the H really breathes better with a t4 turbine housing vs a t3... how true is this?

Also running e85..

 

I'm running a T4 .96 ar hot side. n that's still kinda small.
But up to u. And how fast u want boost to come in
And yes. H series like t4 housings. They are big motors. They need big turbos

 

Its mostly a street driven car but is used quite a bit for drag racing as well. I'd like 20+ psi before 6000 rpms to at least make it semi-streetable.
