Well, I've done it with Bosch K-jetronic, and the principles are the

I believe there's a efi factory system available for your application, 
but it's british, and sucks.(Can you tell, I'm Irish?)

Hego sensors need to be HOT to work, and it won't be if stuffed up
the backside.

Mine is just a bung welded into the turbo discharge. You can pay $10-$20
for a manufactured bung, or find an axle nut off a metric vehicle
with the same thread as a FORD spark plug, grind it, weld it and wala!
