I have a 40 trim (iirc, i measured the wheel and I think thats what it was) t3/t4 turbo from a turbo kit I bought off a 5sfe. I was thinking of throwing on my black alltrac instead of my stock turbo for a bit more power (mainly just to hold boost better). I havn't heard anything about this turbo before, and wondering the estimated power output of it.

Trim means little. Never heard of a 40 trim T4, either - Generally, a T3/T4 hybrid is a T4 compressor assembly on a T3 cartridge/turbine.

Thats a t3 40 trim. Mines a t4 40 trim.

it looks like it flows a touch more then a t3 60


IIRC the messurements were
1.870" / 47.5mm inducer
3.00" / 76.4mm exducer


On T04e turbos they're commonly sized by trim size as they all have the same exducer size.

Whats the inducer/exducer size of the ct26 (i think the MR2/Alltrac is the same)?

Well I pulled out the turbo and notice that it has a 7 blade compressor wheel rather then the 6 blade of a t04e. So it seems the turbo is a t04b super s instead. Its even worse then the t04e 40 trim.

If it still maxes out the stock fuel on my alltrac (like 280whp) i'll be happy.


Now I need to find my caliper again and see what turbine it has. I'm sure its a stage 1 though, but anyone have a list of the standard t3 turbine sizes?
