Fuel injection for the 2000?

I was just wondering if any members had fitted after market fuel injection to the 2000 4 pot? - or if in fact its not worth doing?
 
Easiest way would be with Megasquirt driving a single point injection system using a throttle body of the appropriate size from a scrapyard.

Otherwise you could drill and fit bungs to the inlet manifold to go multiport injection.

Overrun fuel cut has to be worth a MPG or two, and once running you can tune wearing your Sunday best if you felt so inclined :D
 
Yep that's what I was guessing would be the simplest way of doing it

Just interested to see if anyone else has done it to a standard SC ..I know a few who have done other classics ...may be one for the future- got to restore the body first!
 
Isn't it possible to even adapt the SU carb as a throttle body? I've seen MGBs done this way. However the cylinder head not being cursed with siamesed ports like the B (and A) series can take a better, more efficient multiport setup.

One thing that always struck me as interesting was that in the early 1990s when 2.0 injection engines became standard or largish cars, the outputs were typically around 120bhp - not very different from a 2200TC. It took 16V heads to get up to 140-150bhp a little later. And now you can get insane outputs with 1.2 litres totally reliably.

No doubt a well set up injection car would be considerably more efficient than a 2200TC and a lot smoother and nicer to drive. With a 5 speed box maybe touring at 40mpg?
 
I'd agree with you there Peter, you'd probably not get much more power than carbs, but you should be able to attain the same power with better economy - even just having fuel cutoff on over-run has to be worth something. Then you factor in better atomisation, and the ability to program any mixtures you like and you suddenly have a little bit more in hand there too.

Distributorless ignition needed too to get maximum benefits I think.

Would be a good project! :D
 
might be worth looking up the briko injection systems... If they were working on four pots it might give you some hints...?
 
I read a bit about the P7 and the 5 clyinder engines and the intention to use fuel injection http://www.aronline.co.uk/blogs/concept ... -rover-p7/

Ive got a spare 2000 SC engine - needs rebuild- sitting on the engine stand might be fun project to rebuild it with the aim of making it injection

Will keep an eye out for bits...just a thought I guess a TC cam would be best to use with multiport injection

Completeley agree rockdemon "Distributorless ignition needed too to get maximum benefits I think"
 
Put a TC head on the SC engine and you have four separate inlet ports, ideal for 4 injectors and inlets.
 
Four individual bodies would be best, but they'd need sizing correctly to ensure a reasonable air velocity through the manifold otherwise all the power will be at the top end.
 
Why not retain the SUs as throttle bodies and drill the standard TC manifold to take the injectors?
This will result in a nearly standard looking setup, and the only major problem will be to fit an air flow sensor.

I'd miss the tinkering time spent tuning the SU's.

That's a different matter altogether. I also enjoy the "full experience" of owning and running a classic.
But this doesn't mean that i don't understand someone who wants to "play" with slightly different rules.
To be honest i cannot really complain for my twin HIF6s, since i rebuilt and fitted them they do the job without any problems. But if i had a second P6 to play with i would like to see what it could do with fuel injection. After all it was within the plans of its maker.
 
I have no problems tinkering with SUs or keeping the car standard-just think it would be an interesting project,I've seen it done on other classics and always fancied doing it to one of mine at some point

I will be using the P6 as an everyday car -school runs etc on country roads so the MPG improvements would appeal along with the "potential" to be more reliable?!!

And yes it would be more sensible to use the modern for the everyday stuff..but a bit dull!
 
My 2000TC does 31 mpg ( imperial ) on distance running, and about 27 - 28 on local running . This is far far better than my SC did 40 0dd years ago, and I doubt that you will get much better than that with FI

I totally agree! I have just taken my P6 off the road while I sort out re-bushing the front suspension and a bit of welding. My wifes car does its job very well, and I am glad for the chance to be able to use it, but it's not the same! :cry:
 
Certainly looks neat. I like the way it can be disguised by the original dashpot cover.
And I guess the cost comes down if you buy individual components instead of the whole kit.
