how to calculated turbo size for your motor ,like COMPRESSOR TRIM
and turbine housing size and stage trim and turbine wheel trim

i got a h23 i was thinking turbine housing of a .82 stage 2 and a compressor housing .60 and stage 2 turbine wheel

now i got a t3 on the car with a EX .48 and a 50 shot of nos so it kicks end at 2,500 rpms and all it do is spin so i was think about a .82 it should kick end about 4,500 rpms that will be good for me so i can get off the line at the track
so am trying to make about 350 hp with out the bottle so it will be 400 on the bottle
am just going to upgrade my t3 to a t3/t4 or just upgrade my t3 to a ex .82 and a compressor of a super 60

my now full boost at 13 psi with a waste gate un hooked so i need somthing biger

It's pretty doubtful you're going to make 350 horsepower out of a T3. That's probably the limit of a T3/4, from what I've heard - maybe past it.

As far as compressor sizing, check out the last two months of Sport Compact Car. They've had a couple good articles on how to figure all that out.

Try this calculator:

Its Ray Halls and they are usually pretty close.

Also Sport Compact Car had a few tables in them two issues back on choosing the right turbo.

Hey RGAZ, thanks for the link dude, I've having tons of fun with that page and yea, based on 1/4 mile E.T.'s, mph etc.. it's pretty damn close!

IMHO you should let the pros make that decision. I currently make 420 whp on my B18C motor with a T3/T4 at 18 lbs boost. It will not boost any higher than 18 as it as not the right trim, a/r etc. Turbonetics says with a 60-1 HiFi/ Stage V -63 (which is also a T3/T4) it will boost enough to make 500 whp.
Call Turbonetics tech line and get their recomendations. I wish I had before my purchase.
