I HAVE A STOCK 1986 MAZDA RX7 FC3s AND IT HAS ABOUT 135,500 MILES ON IT....WHAT ARE SOME GOOD UPGRADES THAT I COULD DO FOR MY CAR.....I MIGHT NOT BEABLE TO DO THE TURBO CONVERSION DO TO MONEY PROBLEMS SO NOW I NEED TO RELY ON ALL MOTOR.......SUGGESTIONS

 

intake exhaust. good luck because rx7 performance aint cheap at all, and upgrading a NA to satisfy your needs is harder than a turbo.

 

start with a full tuneup and change all fluids

get an exhaust system, and please note that that does NOT merely mean "ungodly large mufflers or tips" - get a system.

get good brakes!!!! (lines, pads, fluid and tires)

search for any intake and throttle body mods you can find

tighten up any slop you can find (i.e. motor/transmission mounts, suspension)

clean the engine (Amsoil Powerfoam or equivalent)

lightweight flywheel

should result in an appreciably different car.

 

what type of exhaust system and flywheel would you preffer????my car came w/ custom headers when i bought it and thermocover and the guy did something with the egnition also....but like i said, what type of product would you recommend and where could i find them.....

I just received my RB header, Bonez cat, and Rotary Performance cat back system. as a kit it cost about $900. I wont be able to install it for a month or so, but while I was at it I wanted to match port the intake. Any links and vivid instructions for the throttle body and manifold? What about the 5th and 6th port sleeves? What gives on those? Modify, take out, or replace with upgraded?

 

how about removing your Caps key to save weight?
