I used one from a 98' KA24DE from Autozone for my RB20. That's for the sensor that runs to the ECU, not the gauge cluster. I believe a Z32 will interchange as well.

and did you verify resistance and part number cross? cause if it reads differently your ecu will be really confused.

impreziv, are you sure about this? don't mean to come off as an *** but, this is my daily and i need a starter soon. i can't afford the time to experiment....

just got off the phone with 2 nissan dealers, they said that:

(Throw out bearing) 30502-21U00 was not a good part #

They said that Clutch Bearing- 30502-45P00 ($33) was a good # and they called this one the throw out bearing???

also, P/N 30501-S0200 has been replaced with P/N 30501-S0284 ($26)

They gave me part # 32202-B9500 for a pilot bearing??

Could somebody with more knowledge than me clear this up? Thanks!

Just in case anyone ever has this issue, the TPS sensor from the Sentra is the same as the plugs on the coilpacks (RB20).

KA24E injector connectors are the same (duh, same injectors) for the RB20DET.

My friend thinks his TPS sensor maybe bad.

I'm sorry, the TPS from a GA16DE is the same as the coil pack connectors for the RB.

The TPS from a KA24DE will work.

What about RB20 flywheel? I was told that the KA works. Can anyone confirm? Also, 95 Maxima clutch is same as NA Z32? And for the love of God, does anyone know what starters are swappable for the RB20?

Don't know the part number for the RB P/S pump but there is a write up on the forum on how to use your KA powersteering pump might be a more cost effective route.

Plug for HICAS pump rear outlet (for using a HICAS pump on a non-HICAS car) is a NAPA BK-7041067 or you can go here - http://www.cgenterprises.com/ and order drain plug # 1009. It's just an M16 bolt w/ a 1.5 thread pitch. If you get the NAPA one you'll need to cut off the the "pilot point" (non-threaded portion) or else it won't screw in far enough. Or just buy a KA24DE pump

The clutch disk is exactly the same one another, same diameter and same spline pattern, the pressure plate on the other hand does not share the same dowel pin pattern, so these are not interchageable.

As for spark plugs, I either had bad luck or found out the hard way that iridium and platinum plug are not design for high heat turbo applications, maybe good under stock boost (meaning running stock turbo) but still when I bought my RB 4 yrs ago, I found a faulty platinum plug on it (the ceramic coating around the tip was loose on it, ready to break off). I still went with iridium sparks after my build-up (running a hybrid GT35R/T04E turbo) and two plugs went caboom after 7 passes on the 1/4 mile. More details here:

OKRB20DET wrote:haha why do u say this? im pretty sure theres people on here using KA short shifters with their RB's with some small modification
Indeed, for people who are lucky enough to have access to an aluminium welder and press drill, its a question of buying a SR/KA B&M shifter (or whatever shifter you prefer), adding about 1/2 inch to the rear of the mounting plate to make it longer towards the back, filling all the original mounting holes, and redrilling them further to the back of the plate, it pushes the whole shifter assembly foreward for proper mounting on the RB transmission. takes figuring out, but very possible, thats what I did. *EDIT* seems like I went a mile longer than I should of, didn't know of this tip until I read about it, lmao: zerothread?id=112010 seems that one hole redrilling is required and changing the striker arm instead, hehehe both ways work

They are identical blocks, I use an RB26 N1 pump on mine, works like a charm, I don't use a collar, unless your thinking about reving the snot out of the RB (8K-8.5K and up), I don't see the use

Have we officially say what replacement part for the coolant temperature sensor (to gauge cluster, not the one prong to ecu) was for the RB25DET?

or is the part 25080-89903- Sensor - Temperature Z32 25080X from the above list it?
