240Zs rule.  They are lightweight, handle amazingly well, and are easy to work on; but what do you do when the reliable L-series engine runs out of breath?   Simple, bring it to Z Car Garage and install a set of 44mm Mikuni carburetors, new header, and a slightly larger exhaust system…. and hold on!!

The amazing change in the dyno numbers only tell half the story.  The fun factor of this car is now light years ahead of where is was when the car first came to us.  The torque now stays strong through the entire rev-range and the increased breathing capacity now allows the engine to spin freely to six grand if you so desire.  There is an increase of FORTY horsepower and the same in torque through the last 1,500rpm.  This is a life changing difference.

One of the reasons this looks so drastic is the inefficiency of the semi-odd dual carb setup that this car came to us with, but the results prove that that this is one huge step in the right direction to making this car about as much fun that the owner can handle.  The car is now using three individual ITG filters to make sure that the newly found airflow is clean enough for government work so please don’t think that we sent this car on it’s way with no filtration.  Sorry that I don’t have any pictures.

On the horizon for this car is a possible camshaft change to get the last bit of power out of this engine so expect a post in the future if this comes to fruition.  The smile on the owner’s face hasn’t left since we gave the car back and it seems we have lit the fire under another early Z enthusiast, we are happy to help.  ZCG
