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. |

I'm also planning to profile the ports, (minor porting) CC chambers, run maximum quench, fly cut heads, Replace everything but the seats in the heads.(if I can keep them-unknown right now). Ceramic coat piston crowns, combustion chambers, valves, exhaust ports, etc.
So worked heads, balanced rotating assembly, normal hot rod stuff... I am starting with a near perfect 73 2.0 core that I purchased from 914Sixer. He is a foundation point for this forum IMO. The original 2.0 heads are near perfect, no cracks that I have found yet. The intake guides are still usable. The exhaust guides are NOT! One exhaust valve #4 show tip damage. I haven't yet decided to use them as new stuff is cheap, but if I was going to start a project that used an original head these are the types of cores I'd be hunting. |
