does anyone know of an aggresive chip for a 1989 Z32 NA with a manual conversion? need to increase torque

You would need to have yours or a socketed ecu to take a new chip, get a chip mapped from John dixon or Andyp on the forum

would it make much difference on a NA machine?

 

 

ive always looked at it for allowing the extra fuel, for more boost. the boost gives the gains then.

boost is from the turbos, can not see it make a huge difference on an N/A but would be an improved with chip, filter, exhaust, pulley.

Thanks chaps, dont need huge speed for hills 90-95 mph poss but BIG torque, have a spare ecu so I will contact those 2 cheers

It does make a difference, mines mapped, for induction kit, stainless exhaust etc.. and most important, removes the rev limiter

That what i ment with supporting mods.
