Does anyone know what injection manifold can be bolted straight on to an x1/9 head? I.e uno, panda or maybe a lancia one? cheers.

Mk1,Mk2 uno turbo and punto GT

cheers Mate. Helps a lot.

The injectors require a little deshrouding of the head at the upper side of the ports otherwise half the spray pattern will be blanked off. All it takes is a bit of crude port matching to make it work.

what do you mean by deshrouding? Should i then match the ports on the head to the gasket on the PGT inlet manifold?

I'm not so sure on the PGT but on the earlier UT manifolds there is a small recess on each port of the head that the injector spray goes through. The gasket needs to be the right one as it too will need the cutout. Using a standard gasket that blanks off that cutout would be pointless.

if it's any help, later tipos/tempras have a similar engine, and fuel injection, though with it being single point, you're better off with a carb.... now i can see why only the turbo uno/punto were mentioned

cheers jimbro. All i'm doing is seeing if its viable to efi an exxey, specially with price of petrol these days!

The answer is yes - Fiat have done all the work for you - just find yourself an old NA 1300 Uno and nick all the bits you need. If you aren't going for the turbo then this is probably even easier.

There is a whole range of old Fiats that used variants of the same SOHC engine that were injected - any of them will do...

There are of course X1/9s that were factory fitted with injection systems.

Thing is - don't go expecting too much by way of economy, the injection system is better, of that there is no doubt but the improvements in economy come more from the camshaft profile. The standard european X1/9 camshafts are closer to what most other european manufacturers would class as fast road profiles. There was a time (many years ago) when the usual camshaft suppliers were actually downgrading the X1/9 profile without realising it.

What you need to do is move peak torque down the rev range so the engine doesn't have to rev so hard, you can then cruise around without much throttle and still get reasonable response. The downside is a loss of top speed and performance in the upper part of the rev range.

The better alternative is to just make your car lighter - it does wonders for economy!

could i get away with installing the the UT or PGT unlocked ECU? or is that asking too much?

Not sure how well the UT of PGT ECUs would work without a turbo but in principle at least the answer is yes. The UT version would be the most likely candidate as it is an analogue system and the adjustments are very simple.

what do you mean its simpler to make adjustments? do you still need to flash it off a computer? Sorry i'm new to injection

The old injection system on the Unos was not digital - no mapped fuelling anywhere - you just had a couple of screws to adjust everything much like you would on a carb.

The later systems were digital and they would need remapping or chipping to get what you want.
