Whoowie! My dual webers and manifold arrived today. They look bad in pictures, but the real thing is absolutely fabulous.
Now, to get them to work effectively. I had planned on going with the stock exhaust manifold, a 2 and 1/4 inch system with a high flow cat and a cherry bomb or the equivalent. Has anyone got any recommendations for a cam or ignition system? What else should I be looking at to get the Webers to work well? I'll be mostly highway with sand or mud, running 4.56's front and rear with 33's.
I run a header with 2" exhaust and a small turbo muffler and dual webers on my 1.6. GOing down hill sounds like a popcorn maker, pop pop pop. Im thinking of restricting it a bit more to get some backpressure back.
Also here in Washington and some other states you have to have a spark arresting muffler to ride on the trails and forest services roads and cherry bombs arent spark suppressing.
I really appreciate the offer and wish I could make it this year. Right now I'm building up the spare engine, both axles are off and I'm in the middle of installing 4.56 r&p's front and rear, new bearings, front b-rings, etc. I'd like to think I could finish in a month, but the dollars have gone out faster than they are coming in this year.
Do you really think a header makes that much difference? It seems that half of the exhaust posts say that Suzuki did a great job with the stock manifold and the other half swear by Calmini or DT. I was actually thinking of looking for a stronger cam or possibly a Sumo II head. Anyone have any opinions here?
If you can't adjust them yourself then try a performance VW shop that deals with air-cooled VW's. It's not that hard to tune and syncronize them yourself if you have a carb synchronizer and a set of instructions. You will love these carbs once you have them dialed in. They sound really neat on a Samurai engine because it is a straight shot through the carbs to the intake valves. When you step into it the engine really comes to life! Prepare for crappy gas mileage though. I am only getting 16-18 mpg best with 33's and 4.57 gears behind a 1.6L. I am lucky to get 160 miles between fill-ups and usually put about 9 gallons in my tank.
