I regards to the 12 trigger wheel I was involved with some bench testing of a hall effect 24 tooth wheel as opposed to a 24 tooth using the stock cas optical sensor and concluded that the optical sensor was the issue rather than the 24 tooth resolution. We spun it up to 6000 rpm on a drill and rev synch captured on a motec, halech and microtech and notice a significantly cleaner signal and square waveform rather than the pyramiding pattern that we saw on the optical sensor. There were also no changes in edge order(skipping triggers). Using a 12 trigger would be no issue based on the observations as the 6000 rpm on the 24 wheel would he equivalent to spinning a 12 trigger wheel at 12000 rpm. Hope this helps.

This is the setup I've been running on my sohc 30 (we braced the bracket up after that pic). Ran a autronic 6-1 chopper disc in cas for cam sync. Went from not being able to rev past 4000, to revving out cleanly to 7. Plus just running smoother all round.

Currently building a 30neo, am I able to replace the disc in the Neo cas?post-78438-0-01277500-1419929375_thumb.jpg

I love seeing home grown innovation! Great work on having a crack at it Murrayis! If you do end up selling it I'm sure you'll sell a bucket load of them!

Huzqld whilst looking slightly agricultural I'm sure yours works perfect too, good job!

Now hurry up and get a kit on the market you blokes before I convince myself to buy the Ross kit @ $2000!

Ill have the first sample batch next week I hope.

Anyone wanting to support the project I can work out a special price for the first run :)

I'm hoping to get the per unit cost to around $90 so the brackets for $180 and sensors around $70 each then all youll need is the chopper wheel and wiring

Cheap cheap

Too cheap, mate you're more than entitled to add some intellectual property value into them, nobody should be expected to put the work into designing something without making a return! You've put the effort in, reward yourself at least a little!

Nah I've taken so much from the community over the years :) time to give back!

Honestly the per unit cost to land them is roughly $50 so plenty in it.

I dont want to make money out of this, the idea is to give to those who want but cannot do!

I've been building my rb24 for 8 years and been dicked around so much you shpuld not have to go through that.

I would suggest contacting Matt at Nistune and asking him if it would be possible to modify the code to accept your sensors. It might not be possible without some sort of interface box to make the waveforms look more like what the optical trigger puts out......but it might be doable. That could/would expand your market space a lot, and make a lot of Nistune users pretty happy too.

You could also look into doing a version with more teeth for those ECUs that will handle it.

Nope makes no difference the only thing to check is the signal voltage, you just have to make sure you use the correct signal wire off the cas if you want to use the factory loom and the other wire off the cas for your tdc cam trigger. That's it and done

It means there would be 36 teeth spread evenly around the trigger wheel.. But you take 1 out so the ECU has a reference point for start up..

Generally you need to attach the wheel to the balancer

You're too humble but that's up to you!!

If you had the time and inclination it would be brilliant to have brackets made that suit all of the more common balancers- Ross, ATI, etc. Most of the common balancers can be ordered with the trigger wheel as an option so they could be made to suit that. A lot easier to bolt on a trigger wheel than having to machine slots into a $700 balancer!

Anyway, good job on giving back to the SAU community, you're a top bloke for it!

    • Just wanted to pop in an update on my setup. The CD swap has been great, I love the mazworks housing for the overall simplicity. I ended up sealing my trans tunnel with a thin sheet of aluminum reused some of the holes on the trans tunnel, and laid some window sealing EPS foam around the edges. Works great, really quieted things down and sealed up the car.  As for the power comment. Right now I am also running about 650whp. with the way the bell housing is attached to the face of the transmission I have zero doubts it would be fine, mainly because the input shaft and main shaft bearings are seated into the bell housing adapter. This means the load is NOT on the bolts to maintain the power, rather into he casing of the bell housing; Yes the bolts are doing some work there, but with both shafts locked in zero worries.  End of the day, the Mazworks solution is the easiest and safest. no need to take your trans to a shop to get milled perfectly, it fits with minimal clearancing, and you can use all your existing clutch and flywheel.  Driving wise the CD has been great compared to the big box, I'll probably swap my final drive at some point. The serial 9 shifter is gooooood, my only qualm is how tight it is, it takes a fair bit to get use to, 5th and 6th are a bit eh/hard to find at times, but maybe I need re-adjusting, and I think my clutch master is very tired and needs a rebuild. 
    • If you are keen, have a look at my build thread. Car is for sale for the right money or straight swap for a F80 M3 LCI.
    • Welcome mate.  No point in over thinking it, buying any one of those cars you mentioned is not a smart or logical choice with the availability of many "better" (re price to performance) cars available to you.  The heart wants what the heart wants, buy whatever it leads you too.
    • Hey everyone! Im so grateful to be apart of this community and ill do my best to be apart of this. Firstly, i'm not disclosing my real name due to in real life circumstances surrounding my privacy and public image (sorry lol) Secondly, The only thing personal I am willing to share is that I'm from Sydney and a descendant of one of Sydneys largest mortgage firms. I got gifted my first ever car, a 2022 Porsche Cayenne and I love it to death. Ive been driving it for about 5 or 6 months now and honestly Im so grateful for my parents for gifting me this vehicle. However recently I've been working my ass off to afford my second car (which I need help deciding soooooo community help me out please?). Once decided, im planning to try modify it myself. Recent I've been thinking about getting a Skyline, particularly a 25GT or GT-V, yes I know overrated as hell, but I'm also considering a Chaser which I recently came to love. However my dream is to one day own a 180SX (So hard to find clean versions and im not really into importing).  Lastly before I send this off, I want to apologize if I sound tacky or pretentious. I try not to and want to genuinely learn from everyone and anyone. (Im no expert in this area) Thanks for reading!
