Hi, i was thinking of building a long stroke turbo engine as I have a block that has bored to 1310, some cooper S pistons and an 84mm stroke crank so total capacity should be circa 1350. My question is what pistons are available that are suitable. I was looking at the Accralites from Avonbar then realised that if I used them they would protrude from the top of the block at TDC. Any help and suggestions appreciated.

You can easily remove two mm from the top of Megas if that's necessary.

A search was tried but didn't answer my question thats why I posted in the help section. Thanks for in the information Vegard, I wonder if it could be done with the accralites I mentioned earlier.

As long as the top ring is a fair way down the piston yes.

Read the book by Smokey Yunick. You'll be surprised about what he says about top ring position...

He thinks that this all is a bit exaggerated. He doesn't like all the volume above the top ring. All sorts of stuff gets ignited down there *wink*

Theres alot of basic info on this site about my engine, how it went together with the trials and tribulations i had, a search will reveal a basic spec, i am for now going to keep the rest and the finer points of how it went together to myself

May sound harsh and i might get a slating for it but it cost me alot in parts and development and i dont want that info just thrown around the net willy nilly

one thing i will say is its not cheap, you can build a k1100 turbo for less
