I was looking at my new BPT motor and checking out the Turbo. I thought that the GT-X ran the IHI-VJ-20 and the GT-R ran the IHI VJ-23. I have a IHI-VJ-22 Turbo on my motor.
Does anyone know the differences in the models?

Here's a link to a picture of my Turbo label.

I can't find anything on the VJ-22. I found this info from Peter Manning:

VJ-6 Very early '85 - '86 BFMR Japanese Imports
VJ-12 Early '86 BFMR Japanese Imports
VJ-13 '86 - '87 BFMR Japanese Imports
VJ-14 American BF Model 323GTX
VJ-16 Upgrade turbo available in the US
VJ-17 Group A turbo used in the WRC
VJ-20 BG Model 323 GTX (1800cc) Jap Imports
VJ-23 323 GTR

 

The VJ-22 is still a GTX motor turbo. It is the same as the VJ-20 except it has a bigger inlet. Hope this helps.

So would the larger inlet make the spool times slower or faster?
Are all IHI RHB5 ballbearing turbo like the RHF6CB on the GTR?

 

rhb5 ihi turbos are not ball bearing
