To Sleeve or not to Sleeve
Cross post from the turbo site.
A friend had a real bad day Saturday when he viewed the cylinder walls of his new expensive rebuild. Head was off to install a NA head, headers and improved turbo.
Every wall was trash. Scores you can hang a finger nail in along with one spot which was really bad looking. This on an engine with about 10 -12 hours.
At any rate he is now looking at getting a used block and pistons and starting over or the possibility of sleeving the block to a 2.6. The bad bore won't permit a first over. The problem is that he needs to get back together for Mid-Ohio on 4/18. That event would let him to break in the new engine before the Mid-Ohio club race. We can get the engine out and torn down in a day. We just need to act on the block part in a hurry to give Ken Farler at Farler Performance time to put it back together, the right way <img border="0" alt="[cheers]" title="" src="graemlins/beerchug.gif" /> BTW, Ken did NOT build this engine.
So let's hear from those of you that have sleeved a motor with good results as well as bad. Include the names of the sources of the good sleeve jobs. Also what pistons you went with.
Thanks,
Alan C.

Get a used block from one of the dismantlers on the list ? I got one from Partsheaven for $250 a couple of years ago. You could aslo try 944Ecology, he is in upstate New York I believe.

I just called Parts Heaven for a block and they priced it at $450. I found that my cylinders were out-of-round, off by 4-5 1000ths, slightly out of spec. In my case, the machine shop will bore the cylinders slightly, and put in 100.5mm pistons - considered oversize or repair pistons. Genuine Porsche parts, and the displacement does not increase by any meaningful amount, so I can still race in the stock class.

Perry,
Not Bodymotion. No signs of wrong rings or case lot quatities of silicone seal. I'm assuming his crank really did get cross drilled.
Jim, Jack
Thanks for the leads.
