Hey guys. Can you tell me what some of the differences in turbos are? I know the basic T3/T4, T25 shit, but what are the T3/TO4B's or TO4E's and stuff?

Also, what size turbo's are some of you running on your KA-T's?

For size, look for flow ratings. www.phoenixturbo.com lists a lot of different flow ratings. 1lb/min of airflow is approx. equal to 10hp at the flywheel. Minus 18% and thats whp.

www.atpturbo.com has a good write up on turbo basics. The forced induction forum (http://www.automotiveforums.com/vbulletin/forumdisplay.php?f=1199) has a really good write up on turbos. Should look into sizing to pick out a nice turbo that will provide optimal gains.

I run a Garrett T04B .60ar S-Trim compressor/.69ar P-Trim turbine. Straight T4.
