T3/t40B- too small?
 

so i found out the turbo i have is
a t3/t40b not a 0e i knew it was small but didnt know it was a B

my turbo seals just craped out, and debating on buying a bigger turbo or rebuild this one


Compressor
TO4B Compressor Housing
H Trim
2.75" Inlet

inducer exducer
2.298" 2.750"


Turbine
20357-03
.48ar STG3

exducer inducer
2.229" 2.559"


my goals is 275whp-300whp

i want to know is it too small?

how much psi would i need to boost on this turbo to hit my goals?

this is a ka24de nissan 240sx motor

i orginally wanted to run 10psi to make 275-300whp, but that was with a t40e

i also read that it spools fast

i want a turbo that will give me average spool and lot of top end:(

revlimit is 6800

Plug in your engine parameters and it will plot a point on a compressor map for you, as well as give you theoretical torque and horsepower outputs.

That turbo is capable of reaching your HP goal. It's the same turbo I'll be using on my semi-build d16z6 but with the .63 ar instead. With the stage 3 .63 ar turbine it's capable of 400+ HP. I also have a garrett stage three 4 bolt .63 ar housing if you're interest in it. LMK
