what kind of boost can it comfortably hold?

also what is the lag like on them?

i wouldnt know stage 2 but i think diff between them is diff size compressor housing stage 3 isnt too laggy at all it gets going just after 2500k and can hold 20psi with ease

25 psi should be fine,

on my old stg2 spec (cossie comp side, rst 0.36 ex side), spool up = full boost (28psi) @ 2500 rpm.

depends on the front wheel, the 60 trims dont like boost - the 55's are fine to whatever you want to push them to.

how would i find out if its got a 60 or 55?

what can a standard t3 cope with if mine would be able to hold 25psi...

Fiecos Dan

55 trim is a 2wd cossie, 60 trim is a 4wd cossie,

you will need remove the comp housing and measure the inducer and exducer diameters of the comp wheel, and calculate it to get the trim, which is a very easy calculation
