Any info about this size turbo is helpful.Its a non ball bearing of course.I think xs.i went to there site but could not find it.it will be going on a b20/vtec 38mm wategate cast iron manifold with revhar intake manifold.t3/t04e

tuned on crome.

 

how much boost?
is the motor stock?
what size injectors?
tubular or log style manifold?
Average temp around your area?
what compression you look at running?
what Octane you going to run?
whats your altitude?

at around 5 PSI with a 50 ar I would say maybe around 240-260whp? depending how aggressively tuned the car is might want to look into the .63 ar for the B20 though

 

stock block 8:8:1 compresion.tubular manifold.gsr head with gsr cams.revhard intake manifold.dont know what size if any are needed for injectors.About 8-10 psi.91 but c16 when racing altitude sucks L.A

 

what is the exact trimming of the turbo?

 

it just says t3/t4 .50 ar

 

ok i would probably say anywhere from 350-450whp.. its hard to say w/o knowing the full specs of it

 

0.58 5 Bolt Standard Hotside
0.63 A/R Cold
0.57 Cimpressor wheel trim
0.60 A/R Compressor
0.63 A/R Turbine
57 Trim

 

probably gonna be maxed out at 450whp range

 

ok thanks.

 

ok thanks.

 

im gonna say around 450.

 

Not bad.

 

is that 450 total or does it add 450 plus wat I already have?

 

What's with all of these 1 post accounts bringing back threads from the dead?

 

I don’t know but I think people don’t want to start a new thread because everyone will say, “did you search?”

That says it’s OK to reply to an old post that you have found searching.

 

To answer the question,
T3/T04E turbos usually don’t have a .50 A/R ratio but there is a common turbo called a 50 trim which is the diameter of the wheel in the compressor(cold side) housing. The exhaust side is typically .48 A/R ratio or .63 A/R ratio. With the smaller A/R ratio you’ll get a quicker spool but worse top end and total power, with the larger A/R ratio you’ll get slower spool time and a bigger total power output.
I’d say with a 50 trim you’ll be lucky to get 450 flywheel horsepower total, probably not 450 wheel horsepower. And that’s a total, not on top of your stock horsepower rating, because all of the air flowing into your engine has to go through the compressor side of the turbo, so it becomes limited with the 50mm sized wheel. You could try a 57 or a 60 trim for a tad more power.
