A question about a 2270 Options

[SLKWrx]

I'm at a crossroad in my 914 experience. After getting all the engine components cleaned up and ready to go, I started my inspection. Turns out the PO never told me there was a good bit of piston slap. So I'm turning a different route and I would like to get more information on the 2270.

Does anyone know where I can get specifics about it? I hear a lot of upgrades from the 1.7 and 1.8L blocks, but not all that much from the 2L block? Is there a reason? Is there a way to get the added stroke without cracking the block?

Anyways, thanks for the info. Can't wait to actually drive this thing that sits in my garage and taunts me (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

If you are starting with a 2.0 liter and you have all (ALL) the fins on your current cylinders, get them honed out to 96mm and get new pistons.

You will want to rework the rods if you had slap to begin with, also check the rod clearance on the existing crank before you remove the rods.

If you find to much play, you will need to take a really good look at the crank to ensure its a good base to build from.

I have a friend that has a very strong 2.6 liter motor with cast iron cylinder...never had oil cooling other than stock, but now he does....it goes about 5-7k before a refresh...

But, a properly cooled 2270 or larger have been built in europe for many years, lots of info across the pond and lots of experienced builders that have done it all, you name it they have built it.
