2.2 vs 2.6
 

My friend just got a microsizer and it is fast as hell. He is completely stock with a 2.2 motor. He raced my other friend with a 2.6 motor and murdered him? WTF? He also burned me with my 2.2. I alos notice that his car has no rattling noise in drive like mine does.. Does he just have a lucky motor?

not all motors are created equal. the 2.2 and 2.6 are just an estimate. he might actually have a 2.3 And also new vs old motor has a big difference. old ones are slower than new ones

Get a kitt racer and try racing him with a new 2.6 see if that works, old motors are just that old and likely dirty.
