Am in the middle of getting an 18rg rebuilt and it needs new pistons.
Currently it has a bore of 89.5 and the pistons are marked 9.7
My engine builder would like to go up in bore to ensure everything is good, so I will probably go up to 92mm bore and possibly 10.5 compression.
Who do guys in the USA use for piston suppliers for these things?
Toysport have some listed - has any one had experience good or bad with them?
Thanks for any hints in advance
