If your transmission is good then you usually have to pump the clutch a few times and go through all the gears back to reverse til it goes in. I usually go from 4th to reverse then 1st to reverse then 3rd to reverse etc...until it goes in. Hope that helps!

It depends on what model of Mazda you have. My 2000 Mazda millenia doesn't. It does have reverse teeth though. I would have to go to a dealer to get another one made for it.
The body kit is $11,000. the engine is most likely a 13b-rew engine with a lot of extras. the car is a Mazda RX7 from the years 1993-1995. Go from there
you lose power and the engine dies... you lose power and the engine dies... Or you go no where very quickly! (for pictures of blown seals go to http://www.noveights.com/id93.html )
Don't try it yourself. Go to a professional rotary shop and it will cost you extra to port the engine to a bridgeport. It requires a full engine teardown and will cost you $3000 in part and labour approx.
