After doing some research I found that the 1989-92 Toyota Supra green injector size 315cc works on the 1990 miata. I have turbo'd the car with a 16g turbo and wanted to know should I use an o ring kit made for my year miata or should I use the one made for the supra? Also what Fuel psi should I set my regulator to? Will I need an emanage system in order to run this injector. I'm only using 5psi.
thanks for your input.

 

use either o-rings they should be the same. at 5psi you can probably run stock fuel pressure

 

interesting....

research huh?
