3F TBI Q's

[Thommo 73]

yes i have searched found nothing i wanted so,

first question what type of injection did the 3F-E come out with TBI/SPI or multi point?


and next has anyone done fuel injection ot the 3F or know where i can find some more info on the subject.
was thinking of using the EA ford 4lt Throttle body injection unit with all the sensors dizzy and ECU, and adapting this to the 3F motor. any thoughts

cheers Thommo

I started asking questions on the 3F two years ago and most of the advice was "Don't waste your money trying to improve it, get rid of it!!"

I know its not the answer you were looking for but its the advice I got

[Thommo 73]

i would like to (get rid of it), but i was reading in some rules on comp events and they say that you must retain the same motor or a motor from the same model, it will be changed later on to diesel but untill then i would like to get rid of the carby as im sick of stalling on hills due to float probs.

[Thommo 73]

so i take it from the lack of response no one knows about the subject or no oone has done the conversion

I think the easiest way would be to find someone removing their injected 3F to fit a V8, a brave man with petrol prices going the way they are.
I regularly repair/service a FJ40 with front coils and an inj. 3F.
I didn't fit it but it is a setup adapted from a XF fairmont multi point.
It runs very well and has been quite reliable.

if gradient problems are the only reason why not go lpg

[Thommo 73]

not enough room for a lpg tank and i hate the stuff.
EFI or engine change are the only choice.

3F-EFI is great! I am no expert and I had a lot of help but early 80 series intake manifold (with injectors etc..), custom injector plate (to accept the injectors above the opening), aftermarket computer, some wiring, elec ign, fuel pump and other bits gave me a sweet setup. The 3F gets a hard time but I love it. With EFI, extractors and a free flow exhaust, she revs like a 4.5 and pulls like a tractor. Ended up costing a bit but works well. Whats so bad about lpg? I run both and if I didn't want the outback range i would've ditched the petrol and just gone straight gas. Sorry for the delay in response - I'm rarely online.

[Thommo 73]

thanks for the reply, and as for lpg mainly the loss of room in the back and the price to put it in, i would got to diesel before lpg but thats probably just me. but the EFI doesn't sound that bad so i might go a head with it.

If you go straight gas you can ditch the petrol tank leaving heaps of room for the gas tank(s). The gas conversion will be cheaper and a far sight easier than the EFI. Just get a huge IMPCO or a gas research system. Sorry to harp on the gas thing - but I am a fan.
