Has anyone changed their PI to an electronic system ?
Discussion
Just a question for interest.
We were discussing the hassle of the old lucas PI setup the other night over beers.
I had 3 2.5PI saloons, all cheap as they were all very unreliable, and I changed them all over to carbs as the PI got worse. I even tuned a 2.5 lump and put it in a kit car after one failed its MOT, with 1.75 inch SUs on a modded manifold. I did get one set up properly once, and it was fabulous..... for about 3 months. All many, many years ago (1980's)
I wondered, because today, you could probably quite easily replace the injection with a DIY setup like the megasquirt, keep all the OE throttle bodies, and have a
reliable, fast, and probably economical PI engine (2500 or TR5,6). You would likely only need a bit of machining for modern injectors, plus a bit of pipework and wiring, and Robert's you father's brother...
It would even look [mostly] original....
has anyone gone this way ? Any Photos ??

Thanks....
Yes, I didn't think about that. A single large throttle body already with a TPS sensor makes better sense, just need to blank off the various holes,
make sure they are sealed up well to a single tube to the throttle body (reuse the original ?).
No alignment or sticking throttles issues either... Neat.... Makes me want one again !!

Thanks Guys, interestin' stuff for an old Triumph L6 freak.....
I have also seen a neat job for the Ford V6 Essex, where the carb (38 DGAS) is stripped to a shell (keep the throttles) and a bracket replaces the top part with two 'mass' type injectors added. The original air pan and filter still fits.
Of course if you've got a Cologne then there's more options and injection mfolds to play with, including the OE Ford EFi.
Great photos !!
