Spline Drive - Opnions, facts, any failures??
Komdotkom replied to mitchum's topic in Engines & Forced Induction
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- 52 replies

Spline Drive - Opnions, facts, any failures??
Komdotkom replied to mitchum's topic in Engines & Forced Induction
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.- 52 replies

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

Traction Arm Length for bump steer
Komdotkom replied to Ben26's topic in Suspension, braking, tyres and drivetrain
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. -
Spline Drive - Opnions, facts, any failures??
Komdotkom replied to mitchum's topic in Engines & Forced Induction
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.- 52 replies

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.

R32 GTR radiator for 333kw + track use
Komdotkom replied to MrStabby's topic in Engines & Forced Induction
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?

R32 GTR EFR 7670 Build
Komdotkom replied to Dievos's topic in Members Cars, Project Overhauls & Restorations
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. -
Thanks Trent, currently looking at alternatives.....
-
I hope that's not true since I asked Kristian directly prior to purchase if they were genuine....

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?

I'm also interested pending pics, drawings and material spec.

RB25 Tomei 256 poncams vs HKS 256/264
Komdotkom replied to LaurelPWR's topic in Engines & Forced Induction
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.

Wanted: 3.9 gear set to suit R200 long nose LSD
Komdotkom replied to WalkyHR31's topic in Wanted to Buy
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. -
Off season engine maintenance or swap?
Komdotkom replied to No Crust Racing's topic in Motorsport Discussion & Builds
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!- 37 replies

Off season engine maintenance or swap?
Komdotkom replied to No Crust Racing's topic in Motorsport Discussion & Builds
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.- 37 replies

Komdotkom replied to No Crust Racing's topic in Motorsport Discussion & Builds
This is the old turbo before I got external gate Kando for it. I couldn't get the target boost to work with the internal gate so gave it the ass.- 37 replies

Off season engine maintenance or swap?
Komdotkom replied to No Crust Racing's topic in Motorsport Discussion & Builds
Nah, I made the crank trigger myself. Still used the CAS for the sync signal though. You only really need 4 teeth so I just made up a plate that bolted onto the back of the balancer with a GT101 in between the timing belt behind the front cover. You won't realise the benefit of moving the injectors if you keep the butterflies in there. If you are racing the car, it should never be below 3000rpm and therefore the butterflies are useless since you have enough air speed at 3000rpm and boost is building so they are just a restriction.- 37 replies

Off season engine maintenance or swap?
Komdotkom replied to No Crust Racing's topic in Motorsport Discussion & Builds
I've still got a CA, it's just two extra cylinders! We did some testing with timing scatter on the dyno with a Snap-On timing light and a scope which showed some pretty frightening variations in timing through the mid range and it was all over the joint up top. I think this is largely due to 30 year old sensors trying to keep up and just failing. Following crank trigger install it was a completely different beast, in fact that was the very first change I made to my Rb after my previous experience. We also took out those stupid NICS butterflys when I moved the injectors.- 37 replies
