Re: Nissan D21 Pickup VG30E swap + turbo

I assume LS smart coils are out of the question?

that would look sweet with mounting studs welded to the valve cover and have the ignition leads facing inwards.

Re: 86 Toyota MR2 AW11 + 4A-GE small port

Finally got around to getting the car running well enough to drive the car.

Did real good on a 30min drive to a car show.
Still lots of work to do. Stay tuned.

Looking great! Is that a TVIS manifold? I thought the small port didn't have it?
I should update the title it's actually a large port with TVIS. I got my terminology mixed up.

Re: Snap on programming header like the OEM's do

What your looking for is Pogo-pin's and sleeves.

https://www.digikey.com/products/en/test-and-measurement/test-probe-tips/622

your best bet would be to 3D print a test fixture for the PCB and mount the pins in the test fixture.

What quantity of boards are you looking to program?
