1988 rx7 gtu na to single turbo
 

I'm thinking about turbocharging my completely stock na 13b. What would be the best way going about turbocharging an na?

There are a shitload of threads covering this on nearly every rotary forum. You probably won't get many useful replies to this one as a result. If you search and get what looks like the best few threads it should cover every detail from options with port actuators to turbo oil feed and return/coolant lines.

What would be the best way? Install a standalone and fuel system, then tune the car NA. Once its running OK that was add a turbo and exhaust and tune for that.
