Hello all,
I'm just doing some research on new oversized pistons for my 1965 1147cc Spitfire engine which is currently at the machine shop being inspected and measured up. It currently has .030 oversized bores and will need to go to either .040 or .060 (depending on how the inspection goes this week).
I found this an incredibly helpful comparison between NOS and aftermarket pistons (http://www.wbclassics.com/tech/tr6/engine/triumph-tr6-cast-piston-comparison). My engine builder is old school and specifically asked me to find NOS pistons if I could and didn't like the quality of County, although I know their quality has dramatically increased over the last few decades (and possibly even overtaken AE).
I was wondering if anyone has a set of NOS .040 or .060 pistons so I can compare prices and see what the engine builder would prefer to use? I'm based in North Yorkshire and learning as much as I can, being in my early twenties, from those who have been engine rebuilding for decades so just want to see whats out there before I go in head first!
It seems like NOS valves, tappets, rings seem to be a little easier to find which is good. Are these considered the best quality or is there an aftermarket supplier in the UK thats best to buy these engine overhaul components from?
Have a look at my car on my profile, I did all the bodywork over university summer holidays a few years ago but now I'm on with a full mechanical/chassis/suspension rebuild during the COVID lockdown!
Many thanks, Oli
