Found a potential track car with berkeleyed up fuel injection. Looking to figure out a challenge friendly (cheap) carb conversion.
Who's done this, what parts do you need, how do you do it, and do you want to come help me do it for pizza and beer? 
I'm open to bike carbs, webers, 220, 221, whatever it takes.
Thanks
Here's a good starting point: http://www.clubgti.com/showthread.php?180712-Jolfa-s-FAQ-How-to-guide-to-bike-carbs
K-Jetronic runs silly high fuel pressure so you'll need a regulator/different pump. It is possible to use the 9A ignition but a mappable system is much better. Manifold, easy if you go for Webers (there's a specific one), if you go for bike carbs then you'll either have to fab one up yourself using the lower half of the OE manifold, or get someone to make you one. If you don't mind a bit of a messy setup it can be done on the cheap, but prepare to spend some coin if you're a perfectionist.
It'll sound incredible but give you abhorrent fuel economy. Have fun!
Stock dizzy has no advance, good for a race car?
I have never seen a good, cheap conversion to sidedrafts.
How are your fab skills? I have seen an 8v with a little downdraft 4bbl run lime a raped ape. Manifold was custom but simple. Probably more challenge friendly $ wise.
Bike carbs and Megajolt mappable ignition?
You'll have to see if someone has already made an adapter manifold or if you have to fab a manifold for the bike carbs.
I wish I had a picture of it but a friend of mine bought a rabbit with a 9A that someone pieced together a hornet class car out of junkyard components. They put a block off plate where the throttle body was and drilled the top of the intake plenum for a Holley.
Just like this random google image hit
The other junkyard part that they and a lot of other folks use is a Saab 900 distributor. It will mount to the 16V just like the stocker and has a centrifugal advance unit.
The car ran OK at high RPM and WOT but coughed and sputtered its way there. it was a laughable mess.
I would eschew the Saab distributor just because the knock sensing unit works so well and is so easy to set up. And then Bike carbs!
At the risk of answering a different question than was asked; in what way was the stock EFI berked? Seems like if it's a matter of dead ECU or wiring, Megasquirt is likely to be about as cheap and a lot easier than hacking together a carb swap, doubly so if you can nab a used basic/early version.
EDIT: Okay, MS won't beat taking a hole saw to the manifold and dropping a carb on top in the $$ race...
A 9a isn't efi. It is a cis system which I usually love, but getting it out of the way of a strong breathing 16v can make for some nice power gains.
It's CIS and according to the mechanic at the speed shop that was working on the car for the seller, it's hosed. He wanted to either find a new FI system to plumb in or drop in a turbo 1.8.
I just want to get it running as quickly as possible so I can get it on the track.
CIS is so simple I cannot imagine any carb swap would be cheaper or less work than fixing it. Repairing it is becoming a bit of a lost art though so techs without the proper gauges just give up.
The only of the shelf manifold for that motor is for DCOE's, so setting those up would be about $1000 if you started with used carbs. Fabbing up a manifold could be an afternoon thing or a few weeks depending on how you did it and then you have the carb choices. I would settle for no less than big sport bike carbs. I have spent hours on the dyno setting up weber DGV's and when right they are OK but Mikunis would give DCOE like throttle response but drive like an SU.
Any carb you mount to the top of the manifold (like that pic up there) will stick out of the hood.
If it's a 9A it should have CIS-E Motronic which is actually pretty straightforward. I would ask the mechanic why it's so messed up, could be as simple as a bad fuel filter, sensor somewhere, dirty ground, etc.
If it was a 8V motor, you could perhaps find one of the Weber 2-bbl carb'd intakes from a 1.7 Omni/Horizon. Put a decent Weber downdraft on it and get on with enjoying carb adjustments :)
Since its a 16V, I'd just fix the stock system, convert it to MegaSquirt or another VW EFI solution (its been successfully done on 924's with VW Digifant).
Hi all, more information. It's running DTA engine management. I've got a question to the seller to see what version he's running. I'm now thinking it might be easier to play around with that, at least at first to see if it can be fixed.
Anyone know anything about DTA?
If its on standalone the issue can be from really simple to absurdly complex. Not a huge dta fan but I have tuned a few. Patience will be key and there is a parameter in the software that says "dont use anything but xx value" and a lot of popular tuners use that number as a part of the tune, which makes everything wonky.
