Works beautifully in an Accord, though, so why shouldn't it in a Prelude?

From what i am told the lower gear ratio's are quite short and in traffic can be a handfull...
but the long top are really great on track....
i have the m2b4 and had the m2a4 ratio's are identical but cornering and drive are greatly improved....

I think these are the ratios:-

M2B4: 1 = 3.307, 2 = 1.950, 3 = 1.360, 4 = 1.071, 5 = 0.787, FD = 4.266
U2Q7: 1 = 3.285, 2 = 2.090, 3 = 1.481, 4 = 1.071, 5 = 0.870, FD = 4.266

As recounted loads of times elsewhere, I'd prefer to lower the ATR's vtec cut-in so that you don't have to rev the goolies out of it before changing up, which means that it should be fine in a Prelude.

The LSD is awesome: I still haven't found the car's limits in 3 years of ownership. Perhaps I'm just a wuss?

M2B4 is gearbox from Lude 4th gen so that gearbox should get higger millage than U2Q7 from Acc type r from 98-2002 year
that why U2Q7 is allways more expensive than M2B4 but that is one think second is that two gearboxes are have diffrent system off lsd U2Q7 is better but if you are not bigggggg street reacer M2B4 is enough to good starts from 0-60

that is my opinion
