It’s me again, trying to cut costs!!!!!
I don't remember seeing/hearing anything about Electronic fuel injection.
Is there any reason why I should not or cannot use an EFI engine?
It would seem that I could buy a low mileage engine from a scrap yard in the States, with all the ancillaries, including carriage for about half the price I would pay for even the lowest BHP engine from the factory recommended supplier.
Does the ECU for these EFI engines need to talk to the gearbox or anything else other than Lambda sensors which I would have to fit to the factory exhaust.

Two reasons.
1. to avoid ending on a Q plate you are only allowed one fully reconditioned componed on the car, this is usually the engine, but you have to be able to prove it's fully reconditioned and not just a 2nd hand unit.
2. An EFI unit will probably come from a fairly recent car thus it will be subject to more strict emission regs and may even need cats, this could cost loads to pass SVA even if you end on a Q.
You have to be very carefull when deviating from the norm it sometimes costs a lot more, my gearbox is a case in point, I decided a 4 speed would be good. I ended up having to get an adapter from the US as its different to the 5 speed, I then discovered it used a cable rather than the hydrolic clutch.. more costly fabrication, the gearchange is opposite way round to the norm so had to fabricate all of that, then the factory drive shafts didn't fit.
Whilst i am very happy with the result (gearing is perfect, gearchange is fast and precise) it ended up more expensive than a 5 speed and took more time to assemble, I thought at the time it would be cheaper! In fact it would have been cheaper to buy a 5 speed and modify the gearing!
If you really want the cheapest option my advice would be to look for a fully reconditioned unit out of one of the mags, people often build a mild unit and then decide full on is what they want and sell the unit cheap. Just make sure you get their receipts.
