    I made it myself.

    I didn't get the car back on Friday as expected, they are going to finish the dash config on Monday so I should have it back on Wednesday. I'm going to have a chat with my local Motec boffin about some strategies to get it working more effectively. I can run a couple of comp tables to compare EMAP/IMAP/Turbine speed and EGT, I think I'll have to pull out a fair whack of timing at higher RPM as the EMAP gets out of control. The engine has fairly high dynamic comp to work with E85 and doesn't take much timing on 98. I'm limited by the class of racing that I'm doing to using 'standard' housings. Obviously you can highflow but the 21u housing is choking the shit out of things and has zero ability to regulate boost so I've got some fairly radical plans for the turbine housing. Car made good power on 98. It's an RB20 (Roy would love it). With the dial indicators, my engine builder setup two at 90 degrees to each other and measured the movement in the pump housing from the centreline then very slowly did up the bolts while keeping the pump housing centred using a nylon hammer and some love taps.

    If you don't want 4WD just use a 370Z box and an adaptor from Collins.

    Yep, you need to set the pump up with a dial indicator and re-dowel as Mitchum has said. Obviously you don't go to these lengths for a basic rebuild. Car was running on the dyno yesterday but ran out of turbo pretty early so had to stop it at 5k rpm as the EMAP was off the charts. I'll post a log over the weekend of rpm vs oil pressure

    Mines got the Spool gears in it too and is on the dyno at the moment, I'll get them to data log a power run on the Motec and post a graph. I've got about 22psi at idle with 80C oil.

    I ended up with the mag sensors after a long chat with a Motec guru who races and maintains a lot of IPRA cars. He did loads of research and was having issues with the hall sensors with missing teeth so moved over to the mag sensors and hasn't looked back. The downside is that you have to muck around with the sensor trigger levels in the software a bit to get really good resolution, but to date they've been excellent. The sensor I'm using is actually for a 60-2 on a GT2 Porsche, they are pretty cheap ~$100. You can download a fairly good spec sheet from here. They are dimensionally quite similar to the GT101 so I was able to use an existing GT101 style bracket with some basic machining. https://www.bosch-motorsport-shop.com.au/inductive-speed-sensor I've got it on the dyno next week so I'll grab a capture under load

    I've got the same setup on mine, but Motec and mag sensors. I made a single tooth trigger for the exhaust cam instead of using the factory CAS. I'll grab a screen shot of the ref sync trace from the Motec if you want to compare the outputs of Bosch Motorsport mag sensors vs Hall.

    If you are doing this type of thing on a regular basis I'd suggest that you invest in a couple of dial indicators and make a jig like this, it will give you the most accurate and repeatable results. Cheap dial indicators are available for as little as $35 these days so for a total investment of ~$100 and a couple of hours you will be able to create a measurement device that you will doubtless use on countless occasions in future.

    I purchased one last year and have put it into my new engine, but I haven't started it yet. Well made and the clearances were perfect, so in theory it should be a good thing.

    I got my kit last week, simple to fit and very nicely made. Certainly a much better option than bespoke jap units, I got a brand new Bosch 140a delivered for $223.

    Be very very careful with the PWR radiator and 'stray current' issues. They have a fairly poor reputation when it comes to warranty replacements. Another good option is Race Radiators in Melbourne if you are looking for a custom setup, they just made me a three core twin pass unit with swirl pot. It was about $900 including the pot.

    Great build mate, the dog box must be a steep learning curve! After having the MCA reds in for a while, what's your overall impression of them?
  15. Komdotkom
    Any news on this? I'm keen to hear if you have managed to pick up any hidden hp with the altered trigger. I'm still hoping that there's a way to get the IWG EFR's to make decent numbers.
  16. Komdotkom
    Thanks Trent, currently looking at alternatives.....
  17. Komdotkom
    I hope that's not true since I asked Kristian directly prior to purchase if they were genuine....
  18. Komdotkom
    I have the cam side (complete) if you are looking for it and I think a mate has the crank bracket. If you are keen send me a PM

    For f**ks sake, I've just put Yaris coils on mine that I purchased from Goleby's. The didn't come in OEM Toyota boxes so now I suspect that they'll be fakes. What dwell times are you using Trent?
  20. Komdotkom
    I'm also interested pending pics, drawings and material spec.
  21. Komdotkom
    I just put a set of Kelfords in mine, let me know if you want a set of HKS 256/264 cheap.

    Have a look at the MRM Racing forum that's hosted in Scandinavia somewhere, they have heaps of great info and a very helpful and active community. Autronic's are fine once you get your head around the program, they just lack a lot of the more modern functions like Flex and and not needing a laptop from the dark ages. I ran one on a race car for years without any issues.

    3.9's are hard to get, in Australia your best bet will be to get a set from a Z31 at the wreckers although they are not in all year models. 3.7 is quite common though and that's in the majority of Z31's which were delivered to Australia. If you don't mind mucking around the older Z cars have 3.7 and 3.54 but you'll need to make spacers for the diff centre as the bolts are 1mm smaller. This isn't an issue from a strength point of view but it's a bit of mucking around to make it work.

    Yes, the ecu still needs to know where the camshafts are up to but the crank trigger keeps your fuel and spark events on time in relation to the piston location. It'd be work looking at whether Nistune can run a crank trigger though. I'm assuming you don't still have the AFM? That's just more aids you need to banish!

    https://www.efihardware.com/products/358/gear-tooth-sensor-1GT101DC Super easy to fabricate, just draw it on an open source CNC program like E machine shop and send it off. Should cost less than $200 for the whole lot. If you want any GT101's let me know I've moved on to a Bosch Motorsport sensor for my RB because of extra teeth and have a few new ones lying around.
