I'm building a new block and at the same time thinking about either upgrade my present turbo or at the very least have it rebuilt.

I presently have a Forward Motion enforcer 3 using a TO4 B housing 50 trim, 63 A/R housing stage II wheel with a TU 3" swing valve.

This runs my 2.2L charger 5 speed with custom intake/exhaust manifolds, ported bigger valve headed engine, custom grind 0.0525 lift roller etc...

The turbo might be considered old school but does work quitewell so I’m not sure of what I want to do.
If I could upgrade, what would you suggest I do? Is there abetter wheel I could use in the existing housing or perhaps a GT style turbo?

I primarily drag race and later spool doesn’t bother me, thecar is presently shifted between 6500 and 7000 rpm.

Any suggestions?
