Get yourself a plenum chamber and intake runners from a 914 Air Cooled Porsche. It has larger intake runners, a nifty full throttle switch and you can also find them in dual Webber configurations. (I've got an AFM if you go thast way). You can change out the whole system but the stock vanagon FI system on 80-83 can't abide with much modifications. You can also get a 2bbl carb adapter to fit your existing intake runners. Check out E bay under 914 to find them. If you get the Vanagon system sealed up with no air leaks, the right timing and the right fuel mixture it will work very well just like it was designed to do. Not likely that ratio rockers are going to give you much improvement unless you put them on a hot cam and heads with larger valves.

has anyone ever tried to modify or replace the stock small bore vanagon throttle body?

I've been looking at the small throttle plate on my 1980 air cooled vanagon and now know why it feels like racing with a restrictor plate.

the throttle plate on a saab 2.0L is significantly larger, I don't think i can change out the stock TB and retain the stock air distribution body (center of intake) but i think i can use one of the 2bbl adapter centers and use a larger TB from another model VW for slightly better responce.

also what is the general opinion on using ratio rockers on a stock 2.0L AC motor?
