THE RB25 VALVE SIZES? I AM TRYING TO FIGURE OUT MY PROJECT ENGINE RESULTS.

I'M LOOKING FOR ANYONE WHO HAS MEASURED VALVE SIZE ON THE RB25DE(T).

THANKS IN ADVANCED.

[PROJECTRB240SX]

ALSO WILL TURBO CAMS WORK IN THE RB25DE?

If your RB25 is from an R33, the cams are exactly the same. I am running cams and head from the Stagea RB25DE and they are the same as my 93 ECR33.

THIS HEAD WOULD BE FROM A RB25DE IN A R32 (THIS SO I AVOID THE VVT)... I DON'T WANT STOCK RB25DET CAMS I JUST WANT TO KNOW IF THEY FIT BECAUSE IF THEY DO THEN I'M GOING WITH THE TOMEI CAM SETUP.

[JonPowell]

SHOULD fit then... I dont see it being a problem then.

[PROJECTRB240SX]

OK THANKS. DID YOU HAPPEN TO MEASURE THE VALVE SIZE?

[JonPowell]

no, but I can if you need it.... I will run out into the shop and do it now.

[JonPowell]

34MM Intake and 29.5MM Exhaust.

THANK YOU.WOW INTAKE IS TINY... THATS WEIRD? OHH WELL, I'LL SEE WHAT I NET.

[PROJECTRB240SX]

YOU SURE ITS NOT THE OTHER WAY AROUND?

[JonPowell]

I will check again...I could have the head upside down...You are correct, I had the head standing on end and it was upside down, sorry... I am gonna edit the other post.

ALRIGHTY, THANKS.

MAN WITH WAY OFF SIZED VALVES THE TORQUE/HP IS MID REV RANGE AND IT IS RATHER LOW. OHH WELL. I'LL HAVE TO CHANGE TURBO SETUP.
