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?

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.

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.

      CD009 RB Conversion

      By TurboTapin · Posted

      These are small points I should actually add to my original post. GKtech makes an extended slave line for this conversion. It's what I use, and it works well. You'll also need a CD009 slave cylinder.  S/R Chassis Z33/Z34 Conversion braided clutch line As for transmission sensors, you'll need to both extend the wiring and replace the connectors. I can't recall which is which, but one is your neutral switch and the other the reverse switch. As they are just switches, just test for continuity with your transmission in neutral or reverse to figure out which is which. Connectors:  VQ35 neutral Switch Connector | Wiring Specialties VQ35 Reverse Switch Connector | Wiring Specialties

      I’ll try and see it could be the release bearing. As for the 4th gear grind maybe clutch doesn’t disengage properly cause it is slightly like very slightly hard to go into first could be due to the slab cylinder pin being short uni clutch is a twin plate.   Ive attached some assembly photos hopefully you can open the link and see maybe detect what’s wrong https://share.icloud.com/photos/0dc2YvW__Hl6jl-l2_0jejjpg https://share.icloud.com/photos/09e0jkWOK-vP48c1cfY6u3ViA https://share.icloud.com/photos/0b4rDmh5R7pK7fb1VtND73a3g https://share.icloud.com/photos/05eeUi_6dC4DVi80jOUYDgb0g https://share.icloud.com/photos/06335TgY1XxyIJal_wkdQLhzw

      Downshifts are harder on transmissions than upshifts, the input shaft naturally slows down once disconnected from the engine so the synchros aren't doing all the work. There's no "natural" tendency for an input shaft to increase RPM. Something is not right there, I don't have a great answer on what. You can try a dedicated GL4 75W90, I plan to switch to Motorcraft XT-M5-QS which is supposedly a very good 75W90 for NB Miatas which have a weirdly sensitive transmission from the factory. I would chase down why your clutch is making a hissing noise, that's not normal. It might be no big deal but in the absence of anything else to investigate I would look at that.
