A31 RB20DET igniter wiring vs R32

Hope someone might be able to help me.  

So I have an A31 Cefiro (stock RB20DET) and bought a new coilpack harness that allows me to ditch the igniter by using different coilpacks with built igniters.  The problem that I've run into is that apparently I have a Series 1 Cefiro which annoyingly uses different plugs than R32 RB20DET. 

My question is, does the wiring on the A31 plug correspond with the R32 plug?  One minute with the razor altering the new harness plug and it will plug in, but I wasn't sure if the existing wiring would fire everything correctly.  I'm in the US so finding an R32 plug to swap my igniter harness plug to is a tricky proposition.

Any help is appreciated.

GTSBoy, if you look at that link it says that harness applies to late RB20DET models.  My car is a 1990, so was most likely built early enough to use the older plugs/igniter.

Hcr32typem , I had though of going that route and swapping connectors to later model ones but couldn't find if wiring matched up to later cars or not.

Having spoken to an Australian expert harness guy and sending photos back and forth and he tells me I have a igniter shared with the Z32 and he has the correct plugs so hopefully everything should be sorted because I'm going to have him make me a harness.

I swapped my ignitor out for a Z32 ignitor in my Skyline. Required repinning the harness' on both ends, or more accurately swapping the connectors side to side from the stock RB wiring. I'm sort of surprised the RB in the Cefiro is that different unless it's closer to the very early RB20 "redtops" from the R31 Skylines.

Hcr32typem, I always assumed that the wiring on Cefiros was the same as Skylines, so imagine my surprise when the plug turned out to be completely different.  Apparently from what I can determine, Series 1 Cefiros basically have silver top RB20s with redtop wiring.  Series 2+ are the same as a Skyline.  Makes no sense, but that's the hand you're dealt sometimes.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
