Any reason a T3 cam sensor can't be used in our 8V'ers ignition? Assuming you have all the later electronics for that set-up including R/T trans/flywheel. Is it possible?

Why? :p

Why? ... So I don't have to use the crappy T3 head ... :P

I dont see why not if you have T-III wiring, sensors and SBEC... looking to go to distributorless?

Exactly. Also looking for the improved fueling that the sequential injector firing might have w/the later ECU. Just need to understand better how it's triggered in the 16v head to see what can be adapted to the 8v. I have a solid T3 bottom end, so this is a logical step for me to take at this time ... if it's doable.

you can't adjust the tune for the 8v head. Your fueling and timing tables are going to be wrong.

Go 90+, its sequential fuel injection.

As Kevin said, right now, not really any hacks out there for the TIII computer so you'd be relying on FWD to alter cals for you, so alot of guessing. Not sure you'd gain anything going this route.

hmmm ... hadn't thought about that. How much "off" could they be though?

how much more air does a DOHC flow then a SOHC? Fuel/Timing changes are different enough from 2.2/2.5 G-head/Swirl to allow the wrong computer combo to nuke a motor at stock boost.

Alot, I had to alter my fuel and pump eff tables quite a bit, plus if your using a TIII bottom end with a swirl head, your compression will be 9:1 or higher unless you open up the chamber, use a thick cometic or use a g-head.

Yeah ... I'll have to think that part through.

Simon 10/4 on the CR.

At any rate ... whats the trigger? Is it in the camshaft?

The trigger? Don't quote me, but pretty sure they just use the cam for injector and #1 sync.

I think he means what does the sensor, sense.

I know the 2.0L/2.4L DOHC has a thing bolted to the end of the intake cam, not sure about T-III.

And yes the cam should only be used for sync to the crank.

Looks like its on the intake sprockets inside flange.

Correct

Yeah, its all cut out and part of the reason proper TIII engines can't go full billet adjustable cam gears, :(
