Hello! here's my .02 worth
I am running dual weber 40 idf's on a 1.7L 914. The acceleration is very snappy w/ a good top end. The car breaths better now than with the stock FI.
I also replaced the fuel lines through the tunnel and installed a new rotary pump in the front trunk (from PP btw). I am very satisfied for the moment. I am prolly sitting around 90-100hp...
I agree that 44's are a bit excessive. You should look at a set of 40 idf's with 1.40 mains. The 1.8 has a pretty low compression ratio
but you should see an improvement.
I am just starting the process of building a 2056. I will be using a GA engine as a base. I plan on getting 140+hp. I will use 44's on this engine.
This configuration appeals to me because I can keep all my stock 2.0 stuff w/o modifying the case etc. I can return the engine to stock w/o to much trouble if that is desirable in the future.
The car will have 9.1 cr, webcam, head work including bigger exaust valves, an external oil cooler, and BMW brakes w/ bigger master cylinder. Then I can start to improve the suspension.
