I am putting together my own turbo kit and am trying to determine what size turbo would be best for my application. I came up with these specs through talking to a couple of people and from what I know about turbo's. If anyone has any suggestions or ideas on other turbo sizes, anything would be appreciated. Mainly i wanted to know what you guys think of this specific turbo. It will be on a stock 1.8 dohc vtec so nothing big. lik 6-9psi.

Garrett T3/T04E
.48 a/r .50 compressor T04E
Stage I turbine
Clipped 11 degrees
Oil cooled
external wastegate.

Thanks for your help.

 

ok, first, please everyone forget about clipping, it kills the efficiency of the turbo... when you clip the wheel, your basically "tricking the turbo to think it is larger".. if this is the case, why not just go larger?

ok, heres my suggestions for a quick spooling, low boost turbocharger for you

turbine:T3
.48 a/r
stg3 wheel

compressor:TO4E
57 trim
60 a/r
hope this helps, and let me know if you have any other questions.
