Is there anybody left that does a decent job of boring cylinders? Or is the concensous that it just isn't worth the time and possibilities of donors cylinders being bad?

I talked with Art at ACE and that was his advice which I value. Just wanted to see if there was any other input.


If one was to by a set of pistons and cylinders from AA do these have to be checked for various quality concerns?

THAT is the real question as you can buy a set of pistons, cyls, & rings for about what a machine shop would charge to bore a set of cylinders...

Same dilemma here........I have several sets of nice Mahle 94 mm cylinders, but want to go to 96. I don't really want to have to go Nikkies $$$$$$ But don't want to go with AA cylinders and piston set...I am thinking AA cylinders and the Keith Black pistons.............Type IV Store.............now what to do about an oil pump...Jerry

I asked the oil pump question the other day.

Someone suggested DRD Heads, they have a 30mm type 1 pump modified to fit a type 4

I just made a torque plate so my local engine machinist can bore cylinders for us.
In a week or so I'll know if it was worth it.

Cool
If it works can you lets us know what he would charge for a set?

Rimco can bore them as can the motorcycle and two stroke machine shops. You can build a torque plate and mount them in the block. Then a regular machine shop can bore them.

I've used Rimco many times for boring cylinders.

how is rimco now? i have heard there quality has gone down hill as of late. i havent used them for a number of years so its just the rumor i have heard.

I had EMW (European Motor Works) in Hawthorne, CA bore my old 2L Mahles to 96mm - they came out great, and it wasn't too big of an expense.

I have three old school machine shops locally that do it. One is a fifty year vw machine shop. My last set that I had done cost me 20 bucks each. They have been in my car for 4500 miles with no prob. I would think that there would be similar shops in any city of half a million or more. I also agree with the bike machine shops.

After over 20 years I gave them the finger...
