I know by slapping on the T04 back plate, compressor wheel, and compressor housing you basically make a full T04 turbo, albeit with a smaller turbine than what you would normally upgrade to if you did a full T04 turbo kit.
Okay, so its pretty high, around 0.80 to 1.00 a/r
I notice that a lot of the "larger" turbos that people use have a high a/r also (around 0.80 to 1.00)...

Newb question: If I were to step up to a larger turbo for peak/top-end power, I'd just be looking for a similar turbine a/r, and a higher COMPRESSOR TRIM, right?
