Can anybody decode the jargon for me? what are the differences?

O, P, and Q trim's are the exhaust trim's for a T4 turbo. Every turbo manufacturer has a different way of indicating the size of the wheel.

Trim Exducer Dia Major Dia
N 2.071" 2.922"
O 2.296" 2.922"
P 2.544" 2.922"
Q 2.693" 3.111"

I wouldn't use a T4 exhaust housing/wheel on any 4 cylinder and definately not one that's intended for street use. the T4 exhaust housings/wheels are quite large and will result in excessive spool time.

Oh, but your little V6 is plenty good enough for one jk

Well, it's not really intended for street use, but I was planning on going with a .82 T3 housing anyway...just curious about the T4 specs is all, so thanks for the info.
Now what about the stage 1, 2, 3,.. wheels? same deal?

Basicly yes..i thought different companys for turbo manufactors listed it differently like that P trim etc; and stage 1, 2 etc;

anyways ...higher the number the bigger diameter of the turbine wheel. and you do need the same size stage housing to accomidate for the wheel also.
