My mate is putting a rb20det into his r33 just as a skid pig to learn to drift.

Now we have a r32 rb20det with loom and ecu.

Dash plug pins done match.

And square plug under airbox pins dont match. Need some advice to set this all up.

We cant even find any wiring info for the RB20e R33 to even begin to figure it out.

So any infomation would be good.

Or any tips to make it run with out it being wired to the car, more like its just sitting there to hold it.

And dont just say get a rb25... picked this motor up for $200 with a rebuilt head.

And getting this wired up will help when his RB30DET goes in as he has a R32 RB25 head. Cheers

done match? so you've done the matching

I believe you mean don't match.. both very different words with different meanings.

Because it'a R33, I would suggest investigating on a R33 GTS-t loom and swap the injector pins to suit. Then splice the sensor wires into the R32 sensors. Of course a RB20DET doesn't have VCT so you can just terminate those wires.

Not really rocket science, you'll work it out.

We got it running found some info from someone thats done the swap.

And regards to the comment about small tyres, I have a friend who drifts a single cam non turbo rb20e r32 and goes out with the big boys. A turbo twin cam rb20det will do just fine. The one problem I have with community is the hate towards RB20'S

fuel pump on switch idea isn't smart.

I would use the ECU to trigger your fuel pump, so when the motor isn't turning the pump stops.. good for when there's a crash, and a fuel line ruptures etc. and there's no fuel being pumped everywhere

Ok well I guess we will sort a new feed for that then, didnt think to far into it at this stage.

Ill have to look more into it because the normal power feed etc was somehow running 12v constant so the car would stay running with the key out as a turbo timer would act. So ill have to either get the ecu trigger to work, may wire up a relay using the ecu trigger and the 12v switched feed and get it going that way, either that or anything that only feeds 12v with the engine running haha. More investigation is needed for the next step... dont worry though guys his car is miles away from being ready to drive

      Mistakes were made, my R34 Story

      I mean, I can confirm the TPS is at 100%.... I can confirm when we installed the TB and setup the cable that the TB was indeed fully open at max pedal travel.. the same 'curve' (WRT MAP vs MAP) existed with the previous setup/TB/manifold as well... No, we did not do a run with no intake connected. I would love to go back in time to do such a run to rule out the intake. It would have also been good to do a run with the airbox lid off. There's a test there where increased IAT vs more available air could be a positive tradeoff. I remember taking the lid off my R34 Turbo setup back in the day and noticing a monster increase, even if IAT's did go up. Could be similar. Hard to test unless I find a very deserted road.

      That's actually encouraging to be honest. my motor was rebuild many years ago but it's probably done less than 30,000kms and fucc all limiter or drift, majority street / drag / roll racing. It'll be fine 💪🏼 I don't even have lines or a can for the cam breathers installed yet, there is zero oil residue or splatter on or around them, it drives beautifully so it seems healthy. Just a ticky lifter, yet they're almost brand new oem genuine Nissan and haven't done many kms at all...

      Have you confirmed the throttle body goes to WOT (and stays there) during the run?

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      I'm having a problem. I think it was mentioned above somewhere but can't see it.  I'm stuck in the cycle of, sand, filler, low spot again, put filler, sand, low spot again, now i put filler again and a thicker portion which seems to have helped but I got low spots in other areas. In the image. Circled in red thats where the original low spot was and the shape is the same as the red out line. I've more or less fixed that (still low spot up the top but now I have low spots where the green circled part is.  Is likely the issue that I didn't start with a course sand paper? I sanded the filler with 240 to reduce the risk of not going to far but maybe the issue is that I'm only taking off enough material to remove some of the filler but not the high spots. I now started sanding with 120 and I think I'm seeing a difference. I did fix one dent the other 2 are f**ked and seems like I made another low spot which is indicated by the furthest green circle on the left handside. Any thoughts and solutions?   Also second image. All of these rock chips, can they be filled in with primer or do i need to fill them all with filler/putty? So many rock chips on mine lol.

      Well, I had an Edward Lee's special edition odo windback car/motor with a RB25DET S2 and I put down 372kW with a good amount of track abuse for 1.5 years before the ring lands decided it didn't want to stick around anymore 🥲 But probably didn't help I kept on smashing try limiter on the track and a few skid pans.
