I've got an 87 rx7 with a very loose shifter. I can put the car in gear and move the shifter like I'm in neutral. Do I need to replace something in with my linkage or just tighten a nut. Is this a common problem?

 

Replace the shifter bushings, there is no linkage on our trannys. Inspect the large ball on the shifter, if it is galled or scarred, it will need replacement too, or it will eat up the new shifter bushings.

 

Besides the bushings, the shift lever has a rubber vibration isolator sleeve between the bottom & top half.
That rubber sleeve can give out giving you a loose feel. (BTDT)

There are some cheap but good short throw shift lever kits on e-bay.
A late 90's Miata lever fits.

 

I'm swapping my N/A for a turbo soon and the engine comes with a trany would that help tighten it up.

 

i did the miata swap cause i had the same problem and not only is it tighter but the throw is alot shorter too

yea the miata shifter feels awesome I did the swap myself. I recommend it to everyone!!

 

I just bought a shift kit off of ebay, but it didn't come with another vibration isolator. Should I go to Mazda for that or could someone reccomend where I could get one?

 

The vibration isolatoer is part of the shifter itself. The shifter is 2 pieces with a molded rubber part inside that holds the upper and lower parts together.

 

It is for the original one, not for a shift kit. I'm talking about the last boot you put down before you start bolting everything together.

 

between 50 and 70 bucks off ebay. and if you get one that doesnt come with the plastic slip cover then that will run you 5 bucks at your local mazda dealership

 

Sweet thanks
