Edit: See a few posts below... there is also a 57 trim

As the title says, there is a 50 trim Master Power (real one) that I can buy at a pretty good price, but they only have it with a 45 or 50 trim (obviously going with the 50), BUT with this size compressor wheel, should I go with a .48 A/R exhaust or a .63? Keep in mind I have a B18B and I'm only looking for about 230 hp. I'm just worried that if I go with the .48 I'll be dissapointed at the top end, but I guess more importantly I'm worried I'll be waiting too long to hit boost.

The only reason I'm asking is because I'm just unfamiliar with a 50 trim and I don't know how it'll affect the A/R choices compared to more popular trim turbos (54, 57, 60, etc). I'm leaning towards .63, but I wanted to hear some opinions. Thanks.

Get the .63 turbine.

Get the .63 housing.

If the turbine wheel is any smaller than a "stage 3" then you REALLY need to get the .63 housing.

It is a stage 3 (supposedly)

Update:
SO... apparently this one also comes in a 57 trim... this makes things a little more difficult.

Now it's between the 57 or 50 trim (both have A/R's of .50 compressor side and .63 hot side)

Keeping in mind of my goals (like 230-ish) on a b18b... would the 57 trim be overkill? Realistically please... I know a lot of you guys just go ***** out... but spool time is a factor on this.

Does this change anything... or should I step up to the 57 trim? Any good reasons?

Opinions now aren't really needed (though you can throw one in)... but I went ahead and purchased the 50 trim .50/.63

I just hope I'll like it.
