89 rx7 wanna update where should I start
 

I have a 89 n\a rx7 wanna upgrade where should I start

what is your budget and what do you want to do with your car? How is the maintenance kept up? How is the condition of the engine?

and how much do you know about the car?

by the sounds of it, not much, don't fast and furious it and throw parts at it, LEARN LEARN LEARN first

I know it had some minor exhaust work done....other than that it's stock

I would like to turbo it but I know o have to do a couple thing before I get to that stage
