I'm torn about whether I want to put a taller final drive ratio in. It's an expensive job, and it will make the car more sluggish off the line. The ideal situation would be to add a taller 5th gear while keeping the current final drive ratio (this also would be a not-insignificant amount of work). |
that 3.7 from a 4.1 wont gain you a whole lot. whether the cost is worth the reward is up to the individual at that point. but I dont think it would be as expensive as you think to replace. the pumpkin itself should be a straight swap, so your cost would mostly come from buying/shipping it from AU. that WILL be pretty expensive, that is for certain !
there are other options, look into aftermarket gearsets for the Miata, Im sure there has to be some available, plus, Im betting someone, somewhere, has a taller 5th gear ?
the Miata has a HUGE fanbase, so Im guessing there should be tons of resources out there. unlike the protege which is sort of like the "basturd" child
