Shankle/AR Ricambi used to sell 85mm pistons here in the USA, but I don't know who made them. 3 inch exhaust is going to be way too big for a 2 liter(ish) engine, but the primary header and collector size will be more critical for power and torque characteristics, anyway...Hi, welcome, etc.
Nice car, more impressed by the std aspects than the mods list, but well - you posted it...
While I'm a paid up member of the brizvegas cynics club myself, boring liners is possible (if not as easy to get done right as boring a block) but implies some expensive pistons (or maybe some creative substitution) - either of which would be interesting - tell us more... And who bored the liners?
Exhaust sounds like it would sound horrible if that description is accurate, but I am intrigued because I want to see what I can get through aft of the turbo on mine... Pics?
