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.

This was the damage caused by the sway bar getting caught. Bend end link and lower arms.

I just finished making new arms. I used .120" for the through hole on the trunnion and shock, .083" x 1.25" tube and .070" sheet for the gusset/ends at the shock and trunnion. All the aftermarket arms leave the trunnion unsupported and they use bushings so they were out for me. These are a little heavier though, 17oz total but no more shimming for caster and I can finally get enough camber as my upper arms are slotted as far as they can be.

I guess your anti-roll bar was in the stock position. Did you move it up?

In full stiff, the end links push it down lower, much lower than stock height. I was lazy and didn't want to cut and re weld the end links. This time I will have it almost touching the body and I'll cut the corners off. I need to run it up above but there's always something else taking priority.
