Yeah, I figure if I'm ripping the engine down for look for other problems, I might as well rebuild with new pistons etc, and AF1 heads. The engine is barely 500kms from its last rebuild, but its compromised now. And at 9,000rpm and 200kph on track, I can't afford a compromised engine. I'm also shopping for a spare engine too, just in case it pops in the middle of the season.
My racing budget is already hit hard now, and I haven't even started the season yet.
