Can you reinforce a 6speed MR Tranny?

Jesus. Must be, like, 1000whp. Very nice. 
I'm not sure how much extra shifting is really involved (I still use 1-4 at the track, I just like the ratios better on the 6), but the 6spd is heavy. I just had to literally bench press mine on last week (engine hoist just wasn't working for me). Sucker wore me out, by the time I was done with all the holding/wiggling.

Also, how are you using the engine hoist? Last time I did it, I put the engine/trans together outside of the car, and then lifted the front of the car as high as possible and lifted the engine/trans into place using the hoist from above the engine bay. Had my wife lift the hoist while I wiggled the engine into place. Worked pretty slick. So, apparently all you need to swap a motor is beer and chicks. Anyway, something to try next time, unless it just wasn't working with the engine already in there.

Yeah, that is a good point too. I have always wondered how much of a difference the 5 spd would make during auto-x, whether it would give me a bit more in 2nd gear so I didn't have to ride the limiter in places. I would say overall it might be a bit of a wash. Don't get me wrong, I love my Shep built 6 spd

I've had TRE build my 6 speed, nearly impossible to give hard numbers on how it will do but it feels great and per TRE it's rated to more than what I'm making torque-wise.
Prob the best trans for road racing is the evo 9 gears with evo 8 3rd and 4th - had Shep build that for me, felt quite good.

I definitely prefer pulling the engine.

I know Jacks Transmissions came out with a 3rd-5th gear set for the evo 8/9 MRs not sure who has used them yet but here's the link:
