G'day guys. Just wondering if there is a sort of "rx7's for dummies" book around or better yet... would someone be able to help me do something about my very stock rx7? It's an 89 and it's an auto... thats about all i know. thing like... performance v's reliability... etc... I have been told ot first get a new air filter and then a 3 inch exhaust..... is this the right thing to do?

 

I don't know if there's such thing as a "rotary for dummies" book out there... but I do know that you don't have to be a rocket scientist to work on a small block... see where I'm going with this?
If you're after speed, but don't know much about cars, I think a [second gen] rx7 is the wrong car to buy.

 

Read as many posts as you can in the 2nd Gen RX-7 forum (as well as that forum's FAQ section). You can also use the search function to find threads specific to your car (ie: NA exhaust)
