Re: this turbo too big for b18b?
 

Exactly what I expected.
You must be able to drive in such a manner that boost NEVER comes on!!! That's Ok.
One thing's for sure, you'll NEVER need to upgrade it!!! :)

A 60 trim T3 with .48 turbine on the B18 is very different: It will break the wheel loose at or before 300RPM and you'll see boost come on pretty easily, even at partial throttle.

That's one more proof that MANY different turbos are usable on the same engine. It all depends on the driver's goals. (and/or what he got a good deal on....)
