Yes, we know a 6 speed is better than a 5.

2,500rpm in second becomes ~1300rpm in 3rd (not good, have to pull ~3000rpm in second to make 1500 in 3rd)
2,500rpm in 3rd becomes ~1550 in 4th (good)
2,500rpm in 4th becomes ~1900rpm in 5th (good).

It was mentioned that your main problem was the 2-3 change.

It was my input and the point I was trying to make (to help you) that for the work of fitting the 6 speed was it worth it? That was for you to decide. And as an alternative, if it were gears you were looking for then a splitter is an easier fit.

MYY

Bellhousing mods
Tailend adapter - potential LT230 nose clearance problem.


Splitter

Bellhousing bolts straight up
Easy adapter to LT230 with plenty of clearance for LT230 nose.

Unfortunately it appears you've taken my input as trying to direct sales, and not on it's face value. Obviously if I wanted to sell stuff, I would say lots of nice things to people (and on forums) and make them feel warm and fuzzy.

Of course, no one in their right mind would fit a LT85, the graph was to show others reading on what your talking about.
