After a few iterations this is what I finally ended up with.

Custom 6 runner intake with 18 pound injectors and single 63mm throttle body
with stepper IAC, EDIS-6 wasted spark ignition, wide band O2 sensor, GP2 cam,
MegaSquirt MSII ECU and integrated wiring harness.

Mechanically it's all pretty straightforward but getting the system tuned is a bit
of a bear and takes some time to get it right, but once done it runs like a charm.

Nicely done MS system.

One of the "opportunities" with converting to EFI, especially multiport EFI, is to tune the intake runners. This is the biggest way for EFI to actually improve torque/power. Many modern designs will use graceful curved intake runners to get additional length in a smaller space.

The secret about EFI conversions that most folks miss is the fuel supply. Special attention is required to insure a constant supply of fuel under all conditions. Those float bowls on a carburetor hide a lot of momentary fuel interruptions that will become much more obvious on an EFI system.

Emile, is there a write-up on your EFI conversion?

Cheers
