It's time to replace my failing Weber 32/36 and I can't decide if I should get another 32/36 or upgrade to a 38. The engine is a 2.0L with an Isky OR-66 hydraulic cam, Sprint exhaust manifold, and Crane XR700 ignition system. The intake is ported as per RallyBob's Torquer/Hot-Street Combo specs. By the time I replace the carb the exhaust will be upgraded to 2" pipe to the muffler and 2 1/2" out the back through two Pace Setter exhaust resonators.
Just can't decide which carburetor to get. Any recommendations will be most beneficial.
Thanks, Brian

The weber is very easily rebuildable, but if all else fails, I would go to the 38.

Brian,

I started with a stock 1.9 with a 32/36 a few years ago. It ran well, but had some lag when the rear barrel opened. I then rejetted it and got rid of the lag. I then replaced it with a 38 because I was building a hot 2.0 and knew I'd need it in the future. It was a noticeable improvement, even on the stock 1.9. I then used the 38 on the new engine for the past couple of years. It has been a good carb, except that it was more sensitive to fuel pressure then the 32/36 was. I had to add a fuel pressure regulator to keep it from flooding.

Our engines are similar. I think the 38 would really wake up a modified engine like yours, compared to the 32/36.

IMHO

Installing a smaller fuel inlet needle from a 32/36 helps here. The 38 DGAS has a larger needle and seat, which is great for higher flow, but not necessary on a stock or nearly stock engine.

you might as well just get a 2.0 FI from OGTS for about $400. easyer to start better milage, more modern, and more "upgradeable".
