Performance Upgrades
 

OK, so the Pacesetter headers are a PITA. Anyone have a recommendation for a set of headers for my '85 Z31? I also want to change the throttle body, and get rid of the air box. Also, what size exhaust pipe works best? 3"?

I would think that all headers would be about the same. But I haven't done them, so I don't know.

As far as the airbox, go with a nice K&N cone filter. You'll need some way of getting the filter connected to the rest of the intake. Most people buy a 5" section of 3" exhaust to clamp both sides to.

And for an NA, you really shouldn't go more than 2-1/2" exhaust unless you have lots of other mods to really bring the horsepower up. Any bigger, and you will have no low end power.

...and from the ashes shall rise a new hope. And it shall be known as "Z". And it will be good.

I've got a Turbo so no headers myself but I know people w/ na cars who used Pacesetter headers and said they don't fit well.I know theres some grinding needed for most headers but these needed more than the usual.I'd check MotorSports Auto or Summit or even CarParts.com.If you want to do the throttlebody thing I can help you out there.I've got some for sell.240sx or Stanza.I'd recommend the Stanza.Good luck w/ the mods whatever you end up doing.
