Rb25 And Neo Throttlebodies.

[Simon-S14]

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

hey trent, yeah done that already but mainly its the bulk ofr the TB and the motor hanging off the side of it that i want to ditch.

Series 2 RS4 stags use the same casting but minus the TC butterfly and solenoid.. something to think about I guess.

[Flargh!]

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

thanks for clarifying that.

now i just need a 33 TB. anyone got one?

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.

Thank you GTSBoy.
