Last Sunday was the last SCCA event until fall, it's too hot and no motorsports until it cools down at the end of September. Everything went great until the drive home. My sway bar caught a nice a pothole while turning off the main road. I sheared the shock bolt off and bent both arms passed repairable. I started on making new lower arms with rod ends.   

Last run until September

That's a bummer to have to go through all that! I hope that solves your engine problems!

I eventually wanted to do forged, low CR pistons and port it, but in the summer/off season. The exhaust ports are very small on the these. I opened the bowls from 81% to 86%. Power wise, it feels the same even with the lower CR. I need to do another 60-100mph in 3rd with the Dragy to see if it picked up or lost time/power.  Two weeks before the pistons I was at 3.14 seconds with a passenger.

The plus side to all this is I was limited on boost with the high CR. I'm still at 8 psi and will go up to 13-14 psi once I do a Dragy run. 10 psi on a 2GR is a solid 400whp on a Dynojet.

The two doors are only engine parts. Left one internal parts. This is the most complicated engine ever. Lower girdle, head spacers for cams. 3 timing chains, 40 bolts on the front cover. It's all together and works as it should.
