Well this weekend I lost 2nd completely 1st was hard to get into and 3rd was grinding... dropped the oil and it was black crud that smelled horrible "my neighbor actually called the gas company because he thought there was a leak" so im subscribed I hope there is a good solution soon!
I'm running the FF340 with 12" wide proxy R888 do you think this set up with hold down that kind of power? What the disadvantages from using the mr2 turbo tranny I hear a lot of high horsepower guys go to?
Wide, I think previous poster nailed it, but let me give a bit more color.
The MR2 trans is a much bigger unit that all-in can add upwards of 50lbs to the car. It reduces the serviceability of the car as it just takes up so much space, and can require cutting of the subframe(I haven't done one, just from what I hear from friends).
The gearing is less than optimal. It has a short 1st, tall 2nd-5th. This is the opposite of what you really want for a fun & engaging car on these street and track.
Redline MPH 8500 on stock sized tires
1st 43 46
2nd 67 78
3rd 93 119
4th 118 163
5th 150 205
So essentially you have a too short first as our stock first gear is with power and then the gears are spaced so far apart that the car falls off the cam and out of the power with every shift.
Our gear set looks like this:
So first is taller to take advantage of the power and then every gear is closely spaced to keep wear on the synchros less and the car on the cam.
We're building this setup for the TVS400/FF400 levels of power & torque.
