CIS vs. Dual carb setup for 83 GTI

[jettaboy1884]

I have an 83 GTI that I will soon be doing some engine mods to. I have found intake manifolds that allow dual sidedraft Weber carbs. This sounds pretty interesting, and I am wondering which is better for performance, staying with the stock CIS injection, or going with the dual carbs? I am sticking with the 8 valve solid lifter head but I am going to P&P it and upgrade the cam.

Someday I plan on using forced induction, so I will want to keep that option open.

If anyone knows about this carb setup and could give some pointers or advice I would really appreciate it.

It would be harder to go forced induction with the carbs.

I posted this question on several other sites, and that seems to be the general concensus...

I do plan on using this as a daily driver and I also plan on making it forced induction someday. It seems that for reliability and consistency, the stock CIS is the way to go...

well, you have some options. with the carb setup you will run a feed line from the tank and a return line. you will have a lot mor power and the unbeatable sound of carbs. then when it comes time for f/i just hook up your fuel rail and you are ready to go, you will however need to run standalone injection. but with megasquirt costing only a couple hundred dollars that isnt a big deal. if you plan on waiting a year or so for boost go ahead and carb the bunny. it will give you a good foundation for boosting it. and cis is no good for putting power to it. it is greatly limited in its potential. however in stock form it is dead reliable.
