Carbs will make more power and if you go the 2bbl or small 4 bbl route should be easy. The legal part all depends on where you live. In general most places dont wont you going backward on technology. The power is there and they do sound good. On the flip side of the coin, carbs can be a pain in the butt to sycronize and get running right. Your mileage will decrease and you do a lot more adjusting when the weather changes. All in all, I would get my FI running right with 4 dollar gas fast approaching.
There are a couple of guys with drag racing Audi Coupes, who have put Fox racks in their cars. So I don't think you would have to replace the steering column. Don't know for sure.
There is not much space in a Fox, so that one in that Fox, with the reservoir on top of the pump is a great idea. Harks back to the 50s and early sixties, when cars used that same system. That is why I recognized it.
They have my car when they pry my dead cold fingers from the steering wheel.
Total threadjack ...but anyways, yea I was unsure whether the column was needed or not. Being that I had money back then I just grabbed it for insurance. I was thinking about mounting the pump where the AC compressor goes and putting the reservoir where the battery tray is. Still up in the air though

If you were a Volkswagen....who would your owner be?
Yes, the stock - and stupid - brazilian unit. Pump and reservoir are mounted together, on the engine, what makes that reservoir cap never works and a lot of steering fluid wanna be friend of other parts of the engine bay.This car has power steering? Reservoir just in front of the carbs?
And the front Solex needed a little work to fit behind the reservoir.
It is awesome. I especially like the bike carb racks of four. People catch a good bit of flack on here about carbs, and needlessly bumping old threads , but I don't get it. I am an aircraft mechanic, and 9 out of 10 of the piston driven planes I work on are carburated. The ones that are injected are mechanical. The pilot has a fuel flow and manifold pressure gauges and meters the system himself through a mixture, throttle, and prop pitch controls. Super simple. The reat have carbs for a reason. The carbs are archaic, big, simple, inefficient, and INCREDIBLY reliable. I have never dealt with a "finicky" carb to date. They are just dirty that's all. So if you could care less about Spotted Owls and the ozone layer then go for it. I took the time to learn my CIS-E system and I'll say that it is great. I like it for the same reason that I like carbs. It is simple, and relatively reliable. But I will say that IMHO, carbs are far more simple, and far more reliable. You just need to be able to tune by sight, smell, sound, and feel. You can't set them up the way a book says and expect them to zip you on down the bricks flawlessly. You have to be your own ECU. Very down and dirty, and very fun for the tinkerer. I think it helps to think about a carb as a FI setup. The injector is just in the throttle body. It is just a slightly different way to deliver fuel and air. For anyone thinking about it I say go for it. Don't do it because you can't figure out your FI. Educate yourself prior to fully considering the swap. Better than FI? No. As good if you don't care about economy? Sure. Competitive when it comes to forced induction? Modern FI hands down. Sound? We all know the answer there. Carbs sound like a gorilla getting attacked by a swarm of bees on crystal methamphetamine. Love it. Carbs are for the nostalgiac at heart. I saw a question posted somewhere about a carb swap and someone replied, "why don't you get a set of bias plies?" Now come on. Be open minded.
in the early 90's when i wrenched for I living, I even got the honor to go to Chicago to train at BOSCH for a week.
I learned so much about different FI systems
with C-jet I think it was #17 pin to get the lamda/dwell out of,
CIS I I believe was voltage and L jet had to come off of the OX sensor.
LH I dont rember.
It was cool- bmw's 320's never used the #17 feature but we spinal tapped them.
I also had a 1964 chevy Nova w/ 250 single barrel, and was getting barely 20-21mpg on the highway
my autocross buddy told me to find and place a weber 38 progressive 2 barrel.
I bought a book on tuning carbs, the adaptor manifold came from
it was not easy but I learned alot!
eventually I learned about baketite insulators and heat shields as the carb was overheating,
end result was more power, and almost 24mpg.
As I worked on bmw's and if I was to keep the car, I seriously considered dropping in a BMW 3.5 six with FI-
fuel economy on all vehicles is always going up, and the amount of power from a standard engine is also
Love FI, and dont really like carbs anymore- but I do understand them.
Well I know either you love them or hate them. I converted my 1990 Fox to a Weber 32-36 DFEV down draft carb (The carb is stock, I have not altered the Jets.) on a Redline Intake Manifold. I love my carb but I'm also running a TT 8V Hydraulic Lifter Camshaft (268 - Street/Sport), TT Light-weight Aluminum Adjustable Camshaft Sprocket 8v Blue, with an Audi 80 dual port exhaust manifold an a custom made short header and TT 2" Mandrel bent Aluminized tubing cat back exhaust system. Walker Dynomax Muffler and 12" tt Resonator. A Flowmaster High Flow 2" Catalytic Converter. A Techtonics heavy duty front motor mount for Mk1 chassis and VW Fox, Shore Hardness of 65 (Stock is Shore 45). The Fox runs great, I can spin the wheels in 1st, and bark the wheels in 2nd and 3rd. My only complaint would be the Redline base fuel pump (P/N: 99009.131) was not able to keep up with my fuel needs. 3 - 3.5 psi is recommended for this carb, but with a wilder cam, header, and free flow exhaust I'm having to run 5 psi. I using a electric fuel pump from a Chevy S10 that had TBI, it works perfect for my engines needs. With all this said, the Fox is a lot more fun to drive and has a nice exhaust note to boot.
