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.

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      R33 GTR running -9 with no tune

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
