my front diff mount is toast right now and I have the 4th gear grind(till I put MTL in). I have 155+K on my '91 NA. It is in great shape overall, but is not worth much money if I tried to sell it because of the mileage. So...I can't really afford to abuse the tranny too much or I might as well throw the car away as it will not be worth it to repair it ;( Someday whne I get a TT or 3rd gen RX7 or SupraTT..........sigh.........then I can beef it up(TT car) and give it abuse without fear of damaging something beyond the value of the car. It's gonna be just a toy though...so I have to move to a place with a garage first and maybe sell the NA to buy a dailly driver. I have a Wrangler, but it is no fun to drive 50+ miles a day, especially in the winter.
