I want to buy a fuel pressure regulator that is best for my 87 rx7 non turbo. I am not really which one would be best for my car. It would be most appreciated if someone could visit http://injector.com/fuelregulators.php and let me know what you think.

also, if you can help me out finding a new wire harness.

Please Help!!

 

Is there something wrong the stock regulator?

Put a post in the For sale section and see if anyone has a harness for sale. I've never looked but you can probably get a brand new one from Mazda for ALOT of money.

 

NA's don't need aftermarket regulators. Stock work fine for what the car needs.
