I have a pair of the following turbos:

IHI branded (from an Apexi kit)
Spec: VA490030 0109
Serial: RHX6 05017C

On exhaust housing casting: P16R

I'm told the turbos are from a Skyline kit that Apexi used to do (the rest of the bits I have are Supra specific) but I'm struggling to find any information about them - if anyone reads this and knows anything can you let me know please?

So far I've found the following on a UK based Skyline site but can't tie it into these particular units:

Power ratings:-

TCW15 - 440ps - Compressor 78mm major, 54mm inducer, 48 Trim
TCW10 - 500ps - Compressor 78mm major, 59mm inducer, 57 Trim
TCW76LS - 520ps - Compressor 82mm major, 56mm inducer, 48 Trim
TCW77LS - 560ps - Compressor 82mm major, 61mm inducer, 55 Trim

Apexi A/R Ratios

P13 = A/R 0.51
P16 = A/R 0.63
P18 = A/R 0.71
P20 = A/R 0.79
P22 = A/R 0.87
P25 = A/R 0.98
P27 = A/R 1.06


So I know I have the P16 exhaust but I can't find anything more using the spec or serial information on them :(

Just a bit of a project I've decided to have a tinker with, I've always fancied twins but didn't want to go too mad, these came up at a price I couldn't refuse :)

It's been a while since I've posted outside of OT so be gentle please, any information you have would be most appreciated.

CW has a similarly numbered one on his GTS I believe...only with a P25 exhaust cause it's single.

Like you I find google isn't too helpful right now. :(

My only advice it to take the compressor housing off the front and do some measuring :)

Turbine ratings for ... TCW10- TCW77LS all have the same trims.


TCW15/ turbine trim:87/ turbine major:61mm/ turbine exducer: 57mm

roughly speaking, like to T60s with .68s.

mcanny did you get that from GTR.co.uk, i think i posted them for Paul E on there?
