*first get the gas flow to the head right, do a good port polish job n shave couple of mm's off the head n hipe the compression.
*get high performance ignition coils, spark plugs n cables.
*now getting to the carbs, depends on what kinda performance u r looking at...... u can either swap to a bigger n better carb, prob the zen's carb, hope it wont be too big for the 3 cylinders....... or simply put in a free flow air filter n change the main jets to bigger units......
*if u still need more performance u can get piper high lift cams........
all this wud surely give ur car a zen beating performance. n all the best |
