I'm going to attempt to convert my 3000GT VR4 to Coil-On-Plug, with a new ECU, and all sorts of goodies, and supposedly the coils from an R35 GTR might fit. I'm looking to get the best fit possible, ideally from a mostly unmodified coil.

I request simply this: measure the distance from the tip of a spark plug to the flat mounting surface that your coil sits on (or the approximate location that the ignition base rests). I used the poke stick of my calipers for this. Bonus points if you can send a small photo.

The goal measurement is 70mm. Longer can be good, but shorter bad.

I would also happily take measurements from other cars. The 3000GT community thanks you for your service, because so far... nobody has discovered a whole lot.

CONTEXT: With the Tein EDFC system, a small three phase stepper motor sits on top each hydraulic damper and controls its damping rate. This generally requires Tein's custom computer, which is a hastle to wire and install. But wiring already exists in the 3000GT if you have ECS from factory, including the button and lights. A custom computer is thus required to make it all work seamlessly; in comes TeinECS.

PROS:

Direct swap in place of the old ECS board, reusing the old case!
Uses the factory button and lights
User reprogrammable, open-source design and firmware (uploads coming soon)
It uses the old ECS wiring to control the 4 motors, with the front and rear separately controllable. (L+R tied together)
Optional, but not recommended due to noise: The system interfaces with the car's speed sensor so it can stiffen damping at very low speed and soften damping after speed has accumulated (anti squat launch, but soft cruise, in medium setting)
Reverse polarity protection in power connection
Ruggedized inputs for safety (voltage regulated using zener diodes)
Motor fault detection via current sensing (STILL IN TESTING)

CONS:

The motors are quite loud, because it operates at a frequency that makes the body ring in the rear. Due to the rarity of three phase steppers, there are no economical drivers out there that are more effective than the simple half stepping solution I've built. Some sound deadening paneling around the rear strut tower will hopefully quiet it, but it likely cannot be eliminated.

Each board will cost $170 with shipping included. You will be responsible for acquiring the Tein EDFC Motors (part number EDK05-12140), and of course, you will need the Tein Flex Z coilovers (Please source these first if you decide to go so far). Nothing else is needed besides some solder and heatshrink to wire your motors to the stock connectors! Installation is exceptionally simple.

I might need some time to figure out this order and payment taking process, and please note, manufacturing lead times could be up to a month, it takes a good chunk of time to get fab done, plus components, soldering, testing, packaging, shipping, etc. These will be made in batches, so I will collect orders for a 2 week period, and then make them all at once. That keeps the costs low for you, and makes it easier for me, because these are genuinely made by hand... as in, I place every component with tweezers, and reflow solder them.

IF YOU ARE INTERESTED, PLEASE DIRECT MESSAGE ME FOR ORDERS. I'll be around

Lastly, I thank those of you who eagerly responded to the last post. This is for you!

R35 ignition coil measurement request, a small favor for the Mitsubishi 3000GT community.
