For me:
Needles show:
2k at 50mph
3k at 75mph
4k at 100mph in 5th.
95 SC300 5-speed.
Do you all have non-stock tire/wheel sizes? Also, how hard is it to get the speedo recalibrated?

An Australian company makes the 'yellowbox' which can fix the speedo.
I haven't heard anyone mention why the inline 6 cars have the gearing they come with stock, but for those that don't know.
Lexus put the 4.10+ rear end gearing in these cars to help offset the power to weight ratio of the inline 6 cars. The inline 6 cars are actually too heavy to make only 220hp.
If you were to swap in a 3.76 diff on a non turbo 3.0, it's gonna be a total dog just about everywhere in powerband.

Yea, that is high. I just checked what my rpms were. My 92 which is stock with the 4 spd auto is at 2825 rpm at 80mph. With the overdrive off it is at about 4000 rpm. Seems to me your overdrive must be in the off position. I would check that out.
