You could do an 8.8 swap and use 3.73 or 3.55 gears.

or you can buy one brand new from Mazda for $500. This is from Mazdaspeed Motorsports Development? I can't find it in the competition parts catalog, they have a zillion other R&P ratios (5.12:1, anyone?) but no 3.63. --Ian |

I need to find a dealer around here for diff swapping. Can anyone explain to me why a 99 5 speed and a 3.63 is fail? Here pretty soon going to be doing a 45min commute each way on freeway alone for school and really want to lower the rpm's for highway use. Sitting at 4k in 5th now at about 80. Would love a 6spd but not in the budget, yet. Or would the 5spd w/3.63 make 1st gear tall as hell?
EDIT: Also is there a chart anywhere with what fits, ratios, and what cars they come from with years? Been searching but apparently my google skill need updating |
FM has a gearing chart on their site somewhere that shows speed/gear. That should answer questions. Running the 5spd with the 3.63 would just put a damper on acceleration numbers- you'd still be able to get the car rolling. Definitely feasible given your commute if you can stand a slower car, but IMO with boost it's not a big deal.

Oh and by "Johnwag and I" I mean "john builds them while I drink and phonewhore". |

Here's the FM link you guys were looking for: http://www.flyinmiata.com/tech/gearing.php

Don't forget that your tach is slow, so it's actually 4200rpm and you're open-loop, getting shitty MPG.

Guess I'll be stock pilling drivetrain parts in the garage. By building them you guys just need a carrier and the gear and you do the work. I'm down, don't trust myself enough to set the lash. Need to sell my 97 so I can afford to be baller. Used 6spd and new r&p here I come. Also curious why the tachometer is slow? Just always reads a percentage low or just lags behind on rev. Any cheap fix? It seams like no car has an accurate tachometer. Guess my question is should a autometer tach possibly solve it or is the tachometer pickup just scetchy. Or is it just the nature of the beast

I'm guessing on my tach, fuel cut will be showing somewhere around 8k, because it's rather optimistic. |
