RB25DET Series 2 into R32 Questions

[32_love]

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,

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 Robbo, that's some very helpful advice!
