Hi all,

I hope it's OK to ask these questions in here, I've tried searching and can't seem to find answers to my specific questions.

A friend and I recently picked up and RB25DET series 2 and gearbox that we plan on re-building to replace my RB20 running gear but to start off with, the engine did not come with the cam gears and I'd like to know what is my best option in order to replace these? I'd like to keep the VCT functionality so should I just be chasing a stock intake cam gear (as my understanding is aftermarket cam gears will make me lose VCT)? And if so, are these interchangeable with rb25 neo cam gears?

Secondly (and I know this has been detailed before but am chasing confirmation), am I better off keeping my RB20 ECU and wiring and getting it nistuned & making the requisite changes to wiring for AFM/VCT etc? Or should I just use the R33 ecu and loom I got with the engine?

Finally, should I just keep my RB20 AFM or is it with worth changing up to a pink label rb25 afm?

If you think I've missed something here, please let me know.

Thanks,

32_love

Yes use factory cam gears, Can't swap r33 & 34 VCT gear

Yes you can use the 32 loom but for ease of tuning just get a Link Ecu plugin and then run wires for VCT & Wastegate solenoid. Nistune is no longer supporting R33 ecu so would need a window switching unit for vct control if using r32 Ecu. AIf going with Nistune go the r35 AFM upgrade so much better than the early afm.
Depending where you are in Brisbane I can help sort wiring & ecu setup with either ecu.

Budget also for simple stuff like new fuel & vac hose, some sensor connectors, probably coil packs and a clutch while you have it apart

    • Thanks for your insight, it being basically useless will impact my decision for sure. I thought it may help the engine breath better I guess. But then again, I have also been told that tuning an RB20DE is also not worth it. Exactly, we follow EU Regulations. There is a bit more leeway on older vehicles. My Porsche 924 came without a cat from factory and managed to pass, they still mentioned that I have quite high emissions on it though.
    • My apologies, I stand corrected. Thanks for registering to mention this! And thank you for actually reaching out to the council to clarify. This is the sensible thing to do and the opposite of what I was alluding you were doing. I may have seen too much outrage and hate being fueled on the internet and it has made me a somewhat cynical old man. Sometimes it is easy to forget that there are real people behind websites and accounts. In my defence, CarExpert and CarExplore do read quite similarly at a glance. I shall try and do better in the future. (Please stick around to get the latest scoops on dealing with old Nissan shitboxes )
    • Don't bother. The poor little RB20 doesn't make enough gas flow to challenge the flow capabilities of even the littlest cat, and you won't make any extra power, and all you'll do it soot up your rear bumper. Plus....is Malta not runing under Euro regs?
    • Hey Daniel, sorry to hear that and thanks for posting up for us at a really hard time I only knew SmoothLine through the forums, we never met as we are based in different states, but when he was most active on here he was quite a while back so not many of the current crowd might remember him. I am pretty sure he was active in the Queensland SQU club but that is defunct now too (times are changing and we are all getting older). Farewell SmoothLine!    
    • Turns out depending on whether the car was equipped with TCS or not there are different signals coming to the dash, meaning there are different speedo clusters.  Wired in a speedo calibrator box from aliexpress and now works fine.
