Well, I am rebuilding the engine completely and put in very light forged JE-pistons, so while having everything out and considering what could be done for small money to enhance the experience even more, that was an easy one. I already have the revlimiter at 7048 rpm with stock internals and maybe the new rotating assembly could take a little bit more, but the injectors will not provide more fuel. So I probably don't raise the rev limit.
