the biggest thing you have to be concerned with is cost... the sho guys have been trying to figure this stuff out themselfs ( more because they kill trannys, not for different gear ratio's) and the only then they have come up with is a company that will make all new internals for about 6 grand (that was before the stock market took a dump). but the SHO guys have a big problem with the diff's coming apart (throws the smaller diff pins though the case). the fix for that what a diff from quafie, but about 4 months ago the last diff was made, but there was talk about another company taking over production of it (this was a while ago, because I haven't been online in about 2 months.) which, to my thinking the diff SHOULD fit in a mtx-3 or lower, but the 1500 dollar price take is about triple what I paid for my car.
if you can get it done, and get it don't at a decent price...with strong steel, I bet you could get alot of guys intrested in this. |

Been awhile since messing with manual trannys. If you are racing 4 cyl. consider the drop between gear changes in the higher gears since no raw power from small motor. Keep the higher ratios closer together, you can let 1 and 2 run out further since car rolling speed less. Of course if worried about mileage you will want better OD ratio, a tradeoff to 4-5 rpm drop problems. One can go further and calculate rpm versus gear to tell what theoretical gear ratio needed next based on motor useable rpm power range. Do not have trans here but many of them have a ratio from input to driven gear then another in the selected gear pair and another for final drive meaning 3 different numbers to correlate to get final overall ratio. Tire diameter another variable. We used to change input and driven cluster to change ALL the ratios, then fine tuning available picking different gear pairs.
If I'm looking right no one has that third ratio set mentioned so assuming that input to rest of trans is 1 to 1. Many times they are not though. |
