Before install, I measured the diameter on bore of the TB and it was definitely 62mm. I was wondering about lean running conditions for other emissions-related reasons, but if anything, the TB seems to have improved performance at WOT. I get on an uphill on-ramp for the 101S and the 4 revs way more strongly well-through 4000rpm. And, the engine is already warmed-up.
I don't note any misfires. The 62 TB is no supercharger, but it is a modest improvement for higher RPM running. Lower RPM I do seem to be able to cruise around more in 5th gear on low mph city streets, so maybe low-end is improved some.
Probably the only other engine mod I am considering is an adjustable MAP sensor (in case there is a lean condition resulting from other intake mods, etc; but performance currently seems good and CARB is a bitch :) . No supercharger, turbo or even headers (nervous about engine mileage and don't really need any more high-end power vs. the costs involved)

Other than repairs, a Locker(s) is/are about the only thing on my buy agenda and I'll probably chince and go with a rear Aussie or No-Slip based on decent reviews of these quieter, modern alloy lunchbox jobs. Using the D35 rear on 29" tires (and no plans for a tire diameter increase), I plan to roll the dice that the D35 can take moderate 4x4 wheeling where a wheel might leave the ground once in a while; axle will likely still break, but Jeez man, 29" was the top size from the factory back in the day; we are not exactly talking 35s, 33s or even 31s or massive, modded 4.0 low-range torque!

:evil: (I feel an, "I told you so", coming a long regarding an upcoming D35 snap on 29s, though)
You know you will never see this rig anywhere near "The Hammers" and its like (and I am just looking to have an easier time on the "Miller Jeep Trail" and maybe some of the Big Bear trails) A second rig may be a different story, though, at least with regards to running hardcore trails and using corresponding big tires/axles
