Re: Building a 2056 Options

[swood]

Anyone know if the KB pistons that one would buy for a 1911 (stock 1.8L con rod) are different than what one would buy for a 2.0L con rod? Is the wrist pin height diff? Just wondering if I need to exchange the pistons I now have.

Also, what is the consensus on what cam and size of carbs?

Thanks.

isn't the pin SIZE different as well? 24mm vs 22? or is it just the height? even if you replace your pistons the 96mm cylinders you have now could work.

IIRC, isn't an 86b a mid-high end cam?

we went with a 163 webcam great low-end torque and pulls good all the way up (IMG:style_emoticons/default/smile.gif) very nice for street, imo.

FWIW, we used AA pistons with the valve relief.


just my .02, but if you have a 1911 now? why go to a 2056? not a big jump for a good chunk of change.. if your 1911 needs a new cam, you can do that... or you can look into 2200(76x96) or 2270 for not much more.

Yeah, I'm a mixed up kinda dude. I'm sitting on a 1911 with a #73 in it, 96mm KB's, and LJet. I'm not convinced that's a good combo. I do have a set of Shubek ceramic cam followers that I bought for $140 new...I'm just sayin...

It's just going to be a daily driver. I am fishing for advice here. And I see what you mean about the 86b vs the 163. I don't really know which would be better for my application, but I'm at the point of trying to evaluate my options. It's not an expensive part, but it sure influences how the motor runs.

My thinking was that since I'm not confident in what I have now and with my (lack of ) ability to deal with FI tuning, it might be better to tweak it a bit up to a 2056 with carbs.

Yes, the pin height is different on the pistons used on the 66 and 71mm cranks. I'll have to swap them out.

My 1.8L heads have been rehab'd. The valves are now 42x36 if IRC. But I think I need to change out my rocker studs, they don't have much thread left on em. I'll try and find a pic of it to get some thoughts.
I appreciate further input.
