? about t3/t4

[29PSI]

yea since it has the .63ar housing can i buy just the turbine wheel ? if so where from? i look on fwd p and turbos unleashed.

No you can't just buy a wheel. It's an internal upgrade that requires re-balancing of the turbo + you'd have to buy a different turbine housing to match the wheel you get so you're looking at getting into several hundred dollars. Just run it as is, it's not the best but not the worst combo.
What kind of head are you running? Is there gonna be any port work/big valves?

[29PSI]

the head is a mopar big valve head its been port and polished.right now it has a mp 460 lift cam but i have a new s60 cam i was thinking of putting in it . well what are some opions on a turbo upgrade? what keeps are cars from using bigger turbos? is it just the space under the intake manifold and the space between the fire wall?

Low rpm spool issues due to poor flowing heads. Couple that with a powerband that stops (for most) by 55-6000 tops.

There seems to be a capable big turbo out there SC61, But your head better flow WELL. We'll see this year. I know of 3 that are going onto 8v cars. 1 2.5L and 2 2.2's. All are well worked over engines. Every bottleneck removed. Last I heard all were running .430 lift TBI cams.

My stage 1 G head spools a S70 like a stocker! I am liking the flow on this G head thats for sure. I notice no lack of low end power either, strange.
