Hey how you doin. Im looking at putting a rb20 in my r31 as the name of the topic might suggest. So if there are other posts on the forum can you post links in here otherwise post up your experience with this conversion.(i.e like how long it took, how hard it is that sort of shit)

Thanks

its relativly easy as far as i know u use all the same mounts, starter motor, alternator...ect, all you need to replace is the motor, box. tailshaft and alter the crossmember. and the wiring loom needs a 5k resistor on it to make the tacho work properly cause the rb 30 has one coil with dizzy and 20 has coilpack on each plug.

Its been a wjhile but i think you use R31 powersteering bracket. bolt straight on.

Make sure you get a mini spool for big fun. The R31club boys should help you out with that.

also get some good swaybars. laters

nothing to do with the coils. stock 31 has the needed resistor(s) built into the ecu before the tacho output. later nissans have it built into the cluster and probably need a different amount. so if you put a later ecu into a 31 you dont have one at all and/or its the wrong amount, hence the need for an external one

      RB20 and 25 NEO differences

      I had no transmission at all so I managed to find a big box manual gearbox from an R34 GTT for an insanely good price in EU. I converted it to push type which cost more than the transmission almost, with parts from Amayama! These engines are very strong and can put out decent power with a properly sized turbo. You can save on money from parts like pistons and rods, and invest those in the transmission and other parts. I suggest you join the RB20 Enthusiasts facebook group, plenty of info and almost daily posts there about 20DE/DET/Neo+T builds. (I hope I'm not breaking any forum rules by mentioning third party platforms, just trying to help the buddy out)

      Yeah, having tried all of those methods including BBQ+recipro/hacksaw, I ended up buying a bush press kit under $150 that works well, like this: https://www.ebay.com.au/itm/355967727167?mkcid=16&mkevt=1&mkrid=705-154756-20017-0&ssspo=sfmmuhxgqhm&sssrc=2047675&ssuid=dJvnaZ11TB-&widget_ver=artemis&media=COPY It basically has a range of pushers and cups with threaded rods between to press out a range of large bushes. The problem with any sawing solution is minimising damage to the subframe side, although it probably needs a quick sand afterwards no matter what solution you try due to damage
