I'm looking at the Empi dual down draft carb kits and had a quick question regarding differences in the carbs themselves.
It looks like they have HPMX or Dual D carbs available. Which one would you choose? Should I lean towards real Webers or Dellotos? The intention here is to use the kit in its stock form initially and later change to port fuel injection using the carbs as throttle bodies much like MB911 is doing with his EFI conversion. http://www.914world.com/bbs2/index.php?showtopic=363246 Being able to remove everything in the bores is critical for me. No fixed boosters or venturis is a requirement. I'm planning on starting with an 8.5-9.0 compression 2056 with a webcam #86. I am planning on having the final engine as a 96mm bore/78mm stroke, but this will be in the future. I believe I should start with 44 mm carbs instead of 40. Suggestions, tips, and opinions would be greatly appreciated. |
