Hey all, does anyone happen to know if the R33 RB25 throttle body is the same bolt pattern as the neo 25? Im looking at ditching the TCS throttle body and want something else that bolts in place.

I know RB20 isnt the same as i have a spare one lying around and compared that.

any help would be appreciated.

just pull the tcs butterfly out if thats your concern :cool:

I take it the tcs butterfly is controlled by the ecu, and when it detects a loss of traction it closes the butterfly a bit to reduce power?

Does any one know how fast it operates or how much it closes the throttle body off?

rs four stagea throttle body is ugly as f**k because its the same body but has a stupid cover over where the motor should be. i hate it

want a rb25det one . but then dunno if the j pipe fits so meh

when i removed the TCS throttle body i used R33 RB25, but had to change the TPS over from memory, i think i had to block off a vacuum line off on the r33 throttle body also. and use the R33 cross-over pipe over the covers.

Cheers

Thread dig... Can i remove the TCS butterfly (2 screws) with no ill effects to the ECU? I have the TCS auto turn off each time anyway, but don't want the system to throw a code. Can't imagine it would, but just wanted to check!

Absolutely. There was actually a recent thread on this very question.

    • I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.
    • A bit late but A disk S13P fit over stock R32 GTR brakes, usually A disk front, O disk rear works.
    • Or, the height of the release bearing is not correct for your combo. Start with the bleeding and checking the slave moves throughout its range when you press the pedal (2 person required), but it is possible for the height to be internally wrong too (box back off to measure.
    • Yes, there's quite a few things that can go wrong during a clutch install. Very unlikely. I have a similar clutch. They (ACS) make good gear. No, it is not normal. It is possible that you just need to bleed the clutch slave. But the new clutch will also have a more aggressive actuation force/pressure, and so your old slave cylinder might be a bit leaky or otherwise compromised, and not up to the extra force required. Or the master cylinder, same.
    • Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in?
