Well, that saves a lot of effort. You going 2 speed for minimum weight?

I'm not really sure. I kind of feel like the answer is yes, although part of me thinks I should put a four speed in there just in case I ever want to take it to the track. But I haven't been to the track in over twenty years, and I'm not putting a cage in this car, so then I think I should just put the two speed in it.

So, a two speed isn't an option. When I looked at the gearing charts for the two speed I realized that second gear is always 1:1, so that doesn't really work with any realistic rear-end ratio I would run.

I'm actually looking now at a G-Force GSR transmission. It's configured similarly to the Jerico, but the G-Force has internal shift rods which allow the shifter to be centered in the tunnel. The side shifter and external shift rods on the Jerico look like they're going to cause problems in the RX-8 tunnel.

I'm sure it's a dumb question and not up on all the rules, but are transmissions basically completely open for whatever in Street Mod?

Your option looks pretty awesome, but I assume you can easily get the gearing where you want it for autocross?

Drive train is almost completely open. It's a bonkers rule set.

Just caught up on this thread. Wow on the piston destruction. Enjoy the rebuild!
