The TO4R and the GT 35/40 have the same compressor side. The TO4R is not BB and never was. HKS does not offer a BB option for this turbo, and unless some other company is taking them apart and rebuilding them with BB cartridges, they don't exist. The exhaust side on a TO4R is your standard P-trim Garrett wheel and housing. The GT 35/40 exhaust side is your standard restrictive somewhere between T3 and T4 HKS proprietary rotary blower. If you are happy with 450-475rwhp at 17-20psi then go with the 35/40. If you want to make that power at 14-16psi then go with the TO4R. In my opinion I think you guys should leave the GT series turbos to the 2L 4cyl guys since that's what they were made for.

I think ppl may have read about a T04R BB from A-Spec's site: http://www.a-spectuning.com/products/rx/turbo.shtml The T04R is not BB.
BTW, where can one get more info on the T04Z...can't seem to find it on Google.

Seriously, the GT35R works pretty good on the 2L 4 bangers, though I think they use the smaller exhaust housing. The original question was a streetable turbo, and the 35R meets that requirement.

Well, the t-04R is a streetable turbo as well. Cheaper to repair if things go wrong. Good top end power(since Dave exhaust ported his car). And proly easier to find too.
I like the quick spool up of the GT35/40, but that might have something to do with the small exhaust flange(T3) and it being ball bearing.
