Hey everybody Im new here and I searched around and tried to find some info on this set up and how it would work....I have a 2003 6MT coupe with a pop charger/ Z-tube and a Borla exhaust and i was wondering if a MD 5/16th spacer would be beneficial for me or would it cause me to run a bit too lean thanks if anybody could help me out with this.

 

i think 1/2 would work very well for you car. since it is a manual. and a mrev2 with the spacer is a nice combo.i dont think you would run lean since yours is a rev up.

 

no rev up in 03

 

rev ups didnt start until 05 and 06 6mt models

03 and 04 models did not have revup - 5at nor 6mt
