Hey guys,

I'm a total newbie when it comes to nissans. (Just sold my MA70 and JZA70 supras and bought a R32 GTST) Now, I want to replace the RB20 with a 25 from an R33, is it a straight plug-and-play affair?

Can I use the RB20 wiring loom, transmission, mounts etc.?

Basically, I can't afford to have the car off the road for more than a coupla days and so the plan is to have the RB25 built (forgies, cams, fuel system and big-ass turbo) in a workshop and then installed as a straight swap when completed.

Will a RB20 Power FC run the whole shebang, or do i need one for a RB25, and will it plug into the loom?

And FINALLY, what sorta power will the R32 'box hold?

Thanks for any help you can give.

hate to rain on your parade but unfortunately mostly the answer is no. The gearbox, especially the clutch don't cope for too long with a heavy footed driver and an RB20. The box will have to switch as well. The diff is just as an essential a swap, as this is just as likely to go. The RB25 electronics have to come aswell, although i am (unfortunatley) not very familiar with the Apexi Power FC.

Are you getting a half cut or just an engine?

Even if you are getting just the engine, it should come with the essentials.

Cheers.

Have fun... this is what I plan on doing once I am of off my P's

The diff is fine,The R32 wiring is fine just change the injector plugs and run the 2 wires for the VVT solinoid then plug in the R33 PFC(can use R32), If you have an S2 RB25 you need to fit your RB20 coils and module to the 25(1/2 hour work tops)If you use the R32 PFC i can sell you a controller for the VVT cheap so it is still easy.RB20 box will be ok if you are gentle but if thats the case you would not want the extra power so change it if you can.

      High temp brake fluid?

      By Komdotkom · Posted

      Reasonably hard, although I haven't run it with the new Endless setup yet. The old brakes were F50's on 335mm rotors and the car did a 1:40.6 at Phillip Island which is a reasonable time, I'm seeing high 600s on the temperature paint. A guy I know ran the Endless fluid at WTAC without issues and he was doing 1:33's I think (Evo) with a 355/332 setup. I don't get out to the track as much as I'd like but we put the car on the hoist and spanner check every bolt and re-paint mark everything, bleed the brakes, change the fuel, check the coolant system and re-bleed blah blah blah before every event. Motorsport is expensive, RB's are expensive so a couple of hours before an event is time well spent. It's also a net time saving because if you can keep your RB from self destructing it saves you time in the long term!

      Hello! I'm new here, I have an R33 GTST that is currently being finished up! Last year was pretty rough, blew two stock turbos so I decided to build the car. Has been down since November, but I get it back next weekend!

      Hello, I believe my car was imported to America in the 2000s by Kaizo Industries. Would anyone be able to help me find more info on them? I've only found all the basic stuff like that paul walker bnr34, them being shutdown by feds, just stuff like that. Any help would be much appreciated, thanks!

      HKS Vcam Step Pro Issues

      By believer · Posted

      I am using Motec M150.  I am not working on the car myself actually.  My workshop is giving all these info, they are quite reputable in the industry and are very familiar with Motec and RBs and have done a few big setups with VCam and single turbo on RBs.  In fact, they built and tuned my engine from day one.  But they are stumped with my engine at the moment and cannot work out how come the compression is so low with the VCam. They told me that they have now swapped in some Kelford cams (without the VCam) and can achieve around 130psi compression and the low end torque is better, but now the engine is doughy as.  It boosts and peaks at more than 1000rpm slower, with twin HKS GTIII RS, it doesn't get full boost until over 5000rpm. I have always thought the VCam was a bit disappointing at the low rpm. To a point I had to ride the clutch a fair bit to get up a small hill from stand still.  That was when I had a clutch.  Now changing to a 8HP, I don't have that luxury and this problem has become a major issue. I am beginning to think the VCam never work since the day it was installed.  Maybe it was just sitting at the most advanced point, that is why it went good at top end but very ordinary at the bottom.  Therefore, with the help of the Holinger 6 speed and paddle shift, as long as it was moving, it drove pretty good.
