Not really sure what sub forum this belongs in, but here goes.
I am planning on a GTX swap in the next few months and was looking at rebuilding the engine. At first it was going to be a simple replace gaskets rebuild, but I've fallen down the slippery slope of; "since the engine will be apart I might as well....".
I'm looking at forged pistons and rods. While I don't have an immediate desire for more power than the stock GTX levels I know I will in the future and figure prudent planning on the engine build will come in handy when I wish to turn the wick up.
Most forged pistons offered for the BP are higher CR than the stock GTX CR, 8.2:1. My question is can the stock the GTX ecu handle an 8.5 or 8.6 CR? I want to avoid det. at all costs. If the GTX ECU can't handle the increased CR, how much power are GTX pistons good for?
I do know Flyin miata can get custom CR pistons made.
