Swap choices, S54, Euro S50, or something else?

it does but it's like 20-30ft lbs. it's not like you're going from 240ft/lbs to 500 or something.

I misunderstood what you said. I guess I have travish325 disease where reasoning goes straight out the door. Yes, there's not a huge jump in peak torque--22 ft-lbs at the crank. The extra revs and VE past 6000 gives the S54 the upper hand, though.

What 5 speed mates to the s54? ZF310? If so, I think a 2.93 or 3.25 would be good. I have similar RWHP and am using that trans, and traction isn't a huge issue with 235 street tires, so r-comps or some track-oriented tire would do fine.

Yup. Any normal M/S5x swap trans.
