what´s the in-/exducer of T3/T04E turbine wheel 48/63ar

[Margus]

Can`t deside witch one to choose for my ca18det. I know 63 is more laggy than 48, but how much? Compressor would be 50 trim I think.Searched but couldn´t find the in and exducer of .46 and .63 turbine wheel.Anyone has this turbo on ca18? Then does it starts build, then does full boost comes and starts to drop? Thank you, Margus

Forgot that it´s stage 3 turbine wheel. So far found different spec with same turbinesT3/T04E 57 trim stage 3 turbine .63ar in. 2.564 ex. 2.215T3/T04E 50 trim stage 3 turbine .63ar in. 2.559 ex. 2.229As you can see, the only diffrence is compressor trim, but why is the turbine wheel different?

The .48 and .63ar turbine housing wheels are the same size, and the AR shows only the ratio.My goal is 400whp with 7500 redline and street use .48 should do the job?

I would go with the 50 trim, .48 housing. Should spool up pretty quickly, and not be choking off too much in 7-7.5K RPM range.
