okay i haven't torn apart the bottom end of the engine so i don't even know if our cars come with them, but do we have balance shafts situated in the oil pan?? i know the sentra se-r spec v has balance shafts that are used to reduce vibration and help balance the engine and also know that there is a kit for them that removes the shafts and replaces them with a plate freeing up about 10hp. my question is this: i found a company (RRE) that sells a balance shaft removal kit for the evo and was wondering if it would work on our cars. here is the link to the kit, scroll down a bit to see it:

There shouldn't really be one for the lancer. It's not making that much power to worry about vibration from the SOHC design.

 

is anyone sure whether we have them or not??

 

Yes we have them.
