2.0 Rebuild Advice Needed, 2056 or 2270? Options

[john_g]

I'm getting ready to rebuild my 2.0 and am considering going to either 2056, or maybe even up to 2270. What are the downsides or problems associated with going 2270, if any?

To the OP, a 2056 or 2275 each have their virtues and possibilities, mostly depending on what fuel system and head/cam combo you plan on running. I went with a 2056 only because it was my first type 4 and it 'seemed' more straight forward. Maybe in the future if time and money allows, I will look into a 2275.

That said, I will share what I did on my 2056. I added counterbalance weights to the stock 71 mm crank. Used H-beam rods (5.375 length if I recall correctly) and the rotating portion of the bottom end was spun balanced as an assembly, with the pressure plate installed. Reciprocating parts were matched for weight and the rods end to end balanced. All galley plugs were pulled, galleys cleaned then tapped for tapered plugs.

The heads is where most of my work was done, I used 2.0 heads and went with bigger valves, 44 mm intake and 38 mm exhaust (stock 2.0 is 42 and 36mm). I enlarged the intake ports to just shy of 37 mm and smoothed them from the back of the intake valve, through the isolator block and through the intake manifold. The cam I chose was a Web #270 with .473" lift and I think .288" duration, on a 108° lobe center. Used swivel adjusters, 44 mm webers and 8.4:1 compression among other mods. I hope to go with ITB EFI in this engine in the future too.

So whatever engine size you decide, I think a well thought out and efficient motor is more important than displacement alone. And if you are going with stock injection, I would say stick with a 2056cc or even stock 1971cc. Then just focus on the heads (valves), cam and compression for the 'mod' portion.

Good Luck on the project! (IMG:style_emoticons/default/beerchug.gif)
