Wanted to introduce myself just in Chris from Kentucky just bought a 1991 Miata. Never knew how fun these cars are it’s lowered on coilovers but got a question found a used ms3x off a 1995 Miata with a 1.8 guys selling would it work on mine or would it be easier just to buy new and go from there TIA

 

Welcome to the forum! Feel free post up a few pictures of your ride as well as any cats you may own. It's also nice to add any current or future plans you have with the car. The more information, the better!

This place is your one-stop-shop for almost all things Miata. That being said, 99% of the questions you come up with have already been discussed in great detail. It's up to you to find them. Be careful, people around here to take kindly to spoon feeding information that can easily be found through searching. The best way I've found to search for the answers to my questions is by typing my question/topic into google and adding "site:miataturbo.net" after. This filters the results to only MT.net.

To answer your question, Megasquirts are made specifically for each chassis. That way the stock ECU connectors plug in with no issues. Because you own a 91 Miata, you would need a 91-93 MS.

 

reppin' the 502 ey? Welcome man.
