No. They are not.

*edit* Or maybe they are apparently..

So far from the ones I have tried they don't even come close. I have a strong feeling no subaru starter will work on the rbs. I did my testing on an rb25det btw. Waste of money but hey someone had to do it

For RB26 or R34 ps pump on a r32/r33 RB20 or RB25, use a 36.5" 3 rib belt. The RB26 and R34 motors use a 4 rib belt while the R32 and R33 crank pulley uses a shorter 3 rib belt. The 36.5 fits nicely, it is used on a 90-96 Z32 N/A power steering pump! K030365 is a gates PN.

I slotted my PS tensioner bracket, but in retrospect that wasn't even needed!

Hope nobody else has to deal with this pump/motor mismatch, but if they do here's your answer....

I have searched and cannot find good information on the rear main seal for RB20 engine.

Does anyone have a US equivilant part #? I heard the KA24DE rear main seal is a replacement, is this true? (Just like for clutch, the Z32 N/A is supposed to be a direct replacement...)

Also, has anyone modified the S13 KA24DE power steering pump to fit a RB20 (in a S13)? I got a RB20 without PS bracket/pump, and want to find a solution. This is going into a S13 convertible.

Thank you for your help!

Does anyone have the above information on Power steering? What about rear main seal? I ordered a Z32 NA clutch kit, I hope that works.

Z32 N/A? I know that works for 25 trans.

What does the RB20 trans cross-ref with? I don't have FAST installed here.

I just installed Fast :-)

I see part number 32272-36910 for pilot bearing which is for 2wd+hi.2wd (CA18I+RB20E+RB20DE+RB25DE).MT.F5 +GTST.M.MT.F5

Which should also be for the RB20DET 5 speed manual transmission R32 skyline with hicas, 2 wheel drive...

I dont have a file for cross referencing... which one is used for that?

Man, I'm shooting in the dark here, but could you possibly use one from an S12 (84-86 200sx USDM) with CA18ET Turbo? I don't know anything about RB20 transmissions Carl H might...

Could you pull it out and compare it to a Z32 NA? or KA? Is it even out of the chassis?

And apparently all pilot bearings for Nissan are the same.. who knew!

RB20 pilot bushing is the same as the na z32. I just used the one that came with my clutch kit.

In Search of a new Throttle Position Sensor:

We have been all over on searching many forums and search engines for this answer. Still we are unable to locate the correct part number for the TPS (throttle position sensor) of my friend's Nissan Skyline R33 GTS25T Series 1 (RB25DET).

I work for an auto parts company here in New York, USA. The easiest answer would be either:

- an aftermarket Part Number- the original equipment manufacturer Part Number- a vehicle offered in the United States with the same TPS

There is no such thing as giving up even after you have tried google.com.au and yahoo.com.au and translating Japanese websites!

Please help a fellow owner out!

common knowledge that S1 and Q45 TPS are interchangeable.. so one would reason to follow that a Q45 TPS would work.
