I need to have a TPE top end rebuilt. Needs pistons and to be replated... not sure who to send the cylinders to and what to tell them. Also what pistons do i need?

I would send him the whole engine and have him look at your crank too. Chances are the bearings need to be replaced.

That might just be some piston transfer. I can help you figure that out if you want. Top end parts in stock. Can help with plating and rebuild if you want or help you do it yourself. Paul is also great to work with. No pressure either way.

Easy way to find out, get some muriatic acid and some q-tips , dip the q-tip into the acid and use it like a small paintbrush , hit the areas where the Aluminum is stuck at, it will start bubbling and turning black, it may take a couple of applications but all the Aluminum will come off , I have done this on dozens of plated cylinders with good success. Muratic acid washes off with water and you can neutralize it with baking soda.
 
Heads up, make sure you get the pistons that are sized correctly to your motor. Some of these pistons for sale that are 20 dollars cheaper do not come cut to fit a 964. It’s up to the end user to cut the pistons.

I remember having to do that on my first 964 rebuild. Nothing like taking a hack saw to pistons your just brought and then having shape the skirts to match and balance.

To each their own, but an hour and a half of my time is worth more than saving 40$.

thank you for the recommendation's. I have been building TPE, or as its correctly known now as CPI Cast Cyls.
Started helping Erik with them way back in the beginning. Anyway, have most everything in stock to repair your new motor

You are right, the wiseco pistons we stock at JSN all have the same skirt length. If anyone wants them precut for a 964, I’m happy to do that. Depending on the original builder, the skirt length can vary so I personally prefer to leave them long so people can match what they already have. If people don’t mind measuring the skirt length of their original pistons, I’ll happily match it on a new set free of charge. Not trying to start any drama. Nothing wrong with buying from TPE if you prefer. Both are wiseco top quality products.

Ive had to do that on alot of rebuilds over the years but i prefer to use a bench grinder as per eriks suggestion.
