Fabbing a manifold doesn’t scare me and linkage requires a little tenacity and patience, but without knowing where to start on jetting is a bit perplexing to me.
I suppose since the displacement is so much higher and the rev range so much lower that it works out pretty well, size wise. :thumbup:
Good! The linkage was actually one of the more fun parts that I had to figure out, and you are right-on with the sizing.
At a basic level, carbs function by fueling for a given air flow. They fuel pretty well on motorcycle jetting because a 2.0L at 7k RPM is flowing a similar amount of air as a 1.0L at 14k RPM... Obviously it's not that cut & dry but conceptually that's the deal.
Also convenient is that bike carbs are very similar in size to our engine ports. My 1.8L is running on 36mm Keihins from a Kawasaki Ninja 750. Most VW 16v guys aim for larger 40mm carbs typically from 1000-1200cc bikes.
Motorcycles have a TON of aftermarket, and carb tuning and upgrade knowledge is readily available. They can get a little pricey if you have to rebuild them (four independent carbs) and I have learned the hard way that they are sensitive to sitting around with Ethanol gas...
Here's my (still incomplete) setup:
I’ve not done any research on the bike carb conversion. The festiva community is generally against modifying these engines since swaps are so easy, but I’m stubborn. The B6T apparently turns these cars into an absolute monster, but I’m not after a monster, just a bit more zip.
I wholeheartedly encourage you to look into it! I've always been a fan of the underdog motors (VW 8v enthusiast) as long as they have some redeeming qualities... In my opinion, it's also a lot of fun to wring out a little high-strung motor on a regular basis, than to have to drive around timidly with a motor that's too powerful...
If you want to go this route, feel free to shoot me a PM. I get on here every few days, and although I am far from an expert I would be happy to help!
