I've been having a look at what i'm going to do to my drive train.....
I've been looking for a subaru r180 plated LSD at a sensible price, I think I may have found one. Its a 4.44 ratio.
Going for 55 profile/15 inch wheels, and going off a B type gearbox ratios
1st 2.906
2nd 1.902
3rd 1.308
4th 1 :1
5th 0.864
rev drop speed
1st to 2nd 2418 39
2nd to 3rd 2186 59
3rd to 4th 1648 86
4th to 5th 952 113
5th top speed 131
Final: 4.4 :1
Using a L28, rebuilt, dynamically balanced crank/clutch/flywheel etc, 40's, 10.5:1, decent exhaust and for example a 'stage 3' type cam, I'm guessing a max of 7000rpm, would this be a save max/sensible target?(not decided on forged or cast pistons yet).
The 4.44 diff should give a nice boost to in gear acceleration, and a 75mph of 3500rpm. Along with the a 10 year old diff and LSD. Should also enable the car to use all of its potential rev range across the whole gearbox. Also it works well if I ever went to the s14's box.
Please feel free to give your thoughts.....
