Hey people, just finished my conversion and am starting to work out the little bugs and also make it look standard for engineer blue slip etc.

Any idea on how to get the tacho to work with the RB20 (previous motor L20ET)?

And my speedo isn't reading correctly plus it seems to have developed a wobble, any ideas?

what gear box did you use?? the speed sensor is in that and if you used the matching box for the rb20 then it should already get the speed signal to the ECU?

the was also a work shop in SA Jaustech that did this conversion years ago they might have the info you are after.

Used the RB20 gearbox, not sure if the ECU is getting speed or not, any idea on how to get the tacho going?

there would be a resistor required to get the signal, i ended up getting a monster tacho in the end.

have a look in the r31skyline forum in a few days (website down for a few days at the moment) as they have info on getting the tacho working with rb20/25 conversions

i sent my wiring off to castlemain auto elecs, i think its near rod hadfield, or maybe the same mob. they will make any wiring loom into a universal one so you can easily wire it into your car. i found them real good and helpful, they are a bit

expensive but they do good work.

Did you get the standard tacho to work though?

yep! without any hassle. Just wired in the one wire to the tacho.

What they do is modify the loom off the new motor to suit your car.

They give you wiring diagrams and everything.

You wouldn't still have the wiring diagram would you?

I'll give you a few bucks for a copy.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.
