Can anyone tell me what to look for spec wise when looking for a T4 for a Cossie?

For example you see them on Ebay with T04 Comp housing A/R.50
T4 Comp wheel.
T3. 48 exhaust housing.

What does "trim" mean too, seen a few saying "this trim, that trim"

Any help would be appreciated.

The car its going on is running greys(for now), RS500 Cooler, L8, 6.7:1 Comp, and revs to 8250RPM. Will shortly be getting Siemens injectors, GoTech management and head work.

He is aiming for high 400bhp figures, maybe even 500 mark, in it and is adamant a T4 is going to be used.

Any help from you lot would be greatly appreciated.

Cheers peoples.

 

Forgot to mention, he loves lag.

BTTT

 

it has to be the 2 part back ex housing and on the front comp housing it should have m24 a/r 70

 

.48 housing? iirc im sure Lee's is a .63 housing

 

Sorry for digging this one out, but can anyone tell me what A/R housings and trims does RS500 T4 have?

 

Rs500 t4 is ar.70 comp and a. 63 exh if that helps. That's all I can remember off mine

 

I think standard Trim is 57 but i could be wrong.
