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!

      Just as a thought, if it's in neutral, thats your drive line disconnect, not the clutch. Clutch slip at the dyno with pedal fully out, is actually adding a second disconnect. So it's not a clutch issue if you're in neutral. Just a bit of friction dragging the output around while in the air.

      "Cheap" bolt on turbo on RB25DET NEO

      By GTSBoy · Posted

      The HG high flow is excellent, and costs about the $$ you're talking about. But it, and probably every other highflow, uses a diffeent core than the original turo, and the original Hitatchi core is quite long. So, I think it is inevitable that there is likely no such thing as a highflow that just "bolts on" with no other effort required. And the same is likely true for HG's outright replacement "bolt on" turbos (the ATR things). And the same is likely true for anything similar from elsewhere. I have no idea if the cheap Chinese/Taiwanese complete turbos from eBay/Temu/etc are as bolt on as they claim. I mean, they claim the bolt onto the NAs as well as the turbos, and we know that can't be "bolt on". But it wouldn't matter because I'm not buying a $169 4 psi turbo for anything other than a paddock basher.

      Bummer...yeah i "need" something to "ease" up the work and for my driving it would be enough.    Iam counting the tune "without" turbo. I do not mean "cheap" like something from Temu around 200 USD, "Cheap" is something around 1000 USD?

      Starter motors used to use the weight of metal (magnets) to provide torque. Now they use (more) current instead. This. It's completely normal.

      So thing that had me stumped, but I think is OK....is that when it was up in the air, in neutral I had it running to bleed to coolant while I put the wheels back on. I noticed the rears were turning (slowly) which I'd never seen before 20250928_163512.mp4     Because there had been an issue with clutch slip due to pedal adjustment on the dyno, I assumed there was still and issue so spent some quality time upside down under the dash adjusting the pedal....but no matter what I did the wheels still turned in neutral. Even disconnected the master cylinder to pedal rod and same. In despair, I even removed the clutch slave so there was no chance of any preload causing it.....still happened. So either: 1. Something is not right in the bellhousing, or 2. Its a thing sometimes with cold, thick gearbox oil Internet says it might be 2, I hope so!
