Anyone use an S2 manual with an S1 differential?
Anybody run a 6 speed manual from 09-11 RX-8 with an S1 differential? If so did you run into any issues?
I see 6th gear in S2 transmissions have a taller gear than S1 transmissions, so highway cruising should be a few hundred RPM lower and maybe gain a little MPG. But I'm not sure if this could lug the engine on the highway either...

Thread cleaned up.
@TeamRX8 my apologies as I missed a prior post but have since addressed it.
Let's get this thread back on topic.
I believe the OP is looking for real world feedback / experience from those who have done this modification and how it's gone for them.

77 cylinders, 4 rotors...
The car I bought from my son who bought it from Smutterbutter, has the same set up. There is no problem at all. The gear ratios work fine together.
I will be restarting my 2007 S1, with stock trans and rear end, I will be able to do an A/B comparison at that time. But nothing negative to report after 60k+ miles driving with the S1/S2 combination.

there are many pages of discussion on the forum on this topic assuming you really wanted to know their experiences.
the topic itself is so old that many are not around any more to regurgitate it for you. An S2 is potentially 13 years old at this point. So is this swap.
I’ve commented on it plenty myself; while it is potentially more durable long term, 3rd and 6th gearing is not favorable at all. From a gearing perspective; the S1 trans and S2 diff gear makes more sense. Mileage may suffer some, but anybody worried about mileage has no business owning a rotary engine vehicle.
