5spd vs 6spd...conversion?

[AutostradaVR4]

Firstly, is one superior? Does the 6spd have more range than the 5spd, will you go faster at lower revs?(in final gear), or is it just more gears?

And also, is it a bolt-on conversion? or are there other things that need to be changed?

its bold on, but you need everything. 6 speed trans, t-case, driveshaft, and rear end. And yes the final drive is lower. There is also a JDM gearing conversion you can do that is even lower gearing than the 6 speed that uses the 6 speed trans with jdm ring and pinion gear, 6 speed t-case, 6 speed driveshaft, and 5 speed rear end. However the gears are very hard to get ahold of.

the 6-speed is superior to the 91 and 92 5-speeds due to being a 25 spline instead of an 18 spline, yet the 93 has the 25 spline and a 5-speed so they are just is good. The 6-speed gears out around 235 mph where as the 5-speed gears out around 215 mph. However, this all depends on what gearing you want. The 5-speed gearing is superior if you are running the quartermile and trapping 120 or less, whereas if you are trapping higher, the 6-speed will be superior.

Excellent info. Thanks guys!
