Will Rb20det Cams Fit Rb25de/t

[dondesoto]

WOULD ANYBODY KNOW IF RB20DE/T CAMS WILL FIT R33 RB25DE/T HEADS . I AM WILLING TO GET RID OF THE V.V.T. ON THE INLET CAM . IT JUST THAT IT SEEMS THERES A BIGGER RANGE OF CAMS FOR THE RB20DE/T . IF THEY DO FIT NO PROBS THEN I WILL USE ADJAUSTABLE CAM GEARS . I INTEND RUNNING THE HYDRAULIC LIFTERS SO THAT LIMITS ME TO 8.8 MM LIFT . MAX DURATION I WANT IS 270 .

Yep. I just purchased a set of R32 RB20DE(T) cams to go into RB25 non-VVT head as part of my RB30DE build up...

thanks for that

what cams did you use ( lift and duration ) and did you use the hydraulic lifters .

thanks

I can say too much, but... I am still using hydraulic lifters. With twin cam motors huge lift isnt necessary and after 7.6mm lift (0.300") the increase in airflow for lift is very, very marginal. Duration determines where in the rev range peak power is made so dont go too much past 270 otherwise the RB30 wont be able to spin fast enough to make the most of the cams...

I had to search hard and long to get the cams I wanted. Ended up finding a set in Japan, being shipped as we speak!
