I've bought a box full of t3 bits.
3 elbows, 2 water cooled bearing housings, 1 just oil, 3 shafts, 2x .38 exhaust housings and 3x .42ar comp housings.

There's 2 comp housings that take a small wheel (40mm at small end) and 1 takes a bigger wheel (45ish).

I know the .38 ex housings are rst, and the small comp housings. Anyone know what the bigger comp housing Is?

The bearing housings seem to be 1mm different in width between water/oil. Oil 48mm, water 49.

Thanks in advance.

RST uses a .36 housing not .38, the bigger comp wheel may be from a Cosworth 4x4 T3, does it have actuator bracket bolt holes on the front?
Pics may help.

Sorry they are .36. they just look like an 8 due to age. And yes the bigger compressor housing does have bolt holes. Any idea what trim comp wheel I should buy to fit to this housing?

I'm building a 1.8 zetec turbo using an ERST exhaust manifold and a T3. Would you use the standard size RST compressor wheel and housing (small wheel) or the 4x4 cos? I'd still be using the .36 turbine housing and shaft.

Cheers.

If you're using a .36 housing then I would not go any bigger than a 50 trim comp wheel or you may get surge, those little housing are very restrictive but of course nice and responsive, around 230bhp if running the turbo hard is possible.

I'll stick to the smallest wheel and housing then just to be safe. I'm after reliability over power. Cheers for the help.
