Why is it that nobody…including Jackson recommending that piston upgrade then? Seems silly that warranty could care less about handing out free pistons at will. Just doesn’t make sense. Also I’ve seen a few 7k and 10k mile testimonials on Jackson turbo with no issues on the pistons. I need more proof than your set up in a race to upgrade pistons on a machine that just had 100 mile service done. But I do appreciate you looking out for other guys running the turbo, its just that I have more faith in the factory warranty than 1 or 2 testimonials.
Just saying its happened to several others as well.
Ours cracked both pistons with the stock JR setup, nothing changed.
But again, i will add it was after a a 12 hour straight race, only stopping for fuel and driver changes. So our case is different.
I believe on a stock JR turbo machine that doesnt get its guts blown out will most likely be fine.
We've also had issues with the turbo mounts and prop rod mounts coming loose. Even with the new norlock washers it still loosesn up after a race. We broke the engine mount that the turbo prop rod mounts to. They've since made the lower prop rod mount with 2 bolts to alleviate the issue.
They have you drill holes in the bottom of the air filter box to drain water out, which was never in the original kit instructions.
Once you flash the JR program the Honda Diagnostic equipment can no longer read the pcm to help diagnosed isssues. The JR tool can read codes, but not any usefull PCM information.
Its a great kit, but looking back after living with it for 3 years now, its far from perfect and needs attention to (in our experience) to keep it together.
