Search function, it's there at the top of the page.

There is no 16v head to use. You'd have to swap a whole new engine in. Only thing that will bolt up to the 924 bellhousing is the Audi 5 cylinder engine, only engine from the same family.

Go to EFI forums and lurk moar ffs. Retrofitting an EFI system to a CIS or carbed car is a pretty involved process, if you have to ask, you're not going to succeed.

I'm assuming your in england, so you would have high comp pistons, you can swap to a turbo head without to much difficulty if you are planning on an efi conversion at the same time.
Any aftermarket ecu will suit, emerald, motec, wolf or megasquirt, etc just be aware if you are programming it yourself it is often advisable to have someone who also tunes or uses the same system around locally to get advice from...
you would need to make some inserts for the injector and a fuel rail/regulator, but you can run the system of the ecu's internal map and just retrofit a tps throttle sensor.
The efi conversion will be more involved than the head swap, keep the stock cam to start with and swap it out later if you really get itchy pants as efi will open your otions for turbo/supercharging if you want to.
Get the intake manifold with the turbo head, you can still use the n/a manifold but have to port it and move the bolt holes a little.
If you have a budget now would be a good time to speak up, as there are a few people making conversion parts like endwrench (fuel rails) and there is talk of an edis adapter in a group buy if you get involved.
Good luck

The VW 16v will fit as the Fox uses this engine block. you will need to use the Golf/Jetta intake with the Fox clutch assembly. The 924 bellhousing imitates the Audi transaxle used by the Fox.

Not the current Fox but a car that was imported to the US 1986 to 1993 and it had a 1.8 motor:

NO NO NO. VW and Audi have a common bolt pattern at the bell housing! Thats why the 4000 is able to use a 5 or a 4 cylinder engine with the same transmission. this also transfers to the 924 bell housing. The smaller 4 cylinder engines have a completely different bolt circle on the crank. That is why the fox clutch is needed. The Fox uses a 924 transmission also used on 2wd Audis operated by a cable.

Get with it guys, this is starting to get annoying

The 16v motor from the Golf/Jetta/Scirocco is a BOLT IN just as the 5 cyl.

And furthermore what the hell are you talking about bore and stroke for? That makes no difference here. Any VW motor will fit into any VW chassis from '75-'05. VR6's are hard to put in rabbits but it does fit! The 16v came in euro market Audis and VWs well into the new millenium.

There is no 16v head for your truck based motor. GET RID OF IT!!

The VW works... 'nuf said
