370 for thump_rrr tensioner
250 for VMP tune
100-150 for misc. items for the install
----------------------------------------
6795 give or take total and i havent even upgraded the tires, wheels, clutch or suspension

oh well, she is a blast to drive. 331 gears work good with traction if you are not mashing the throttle, going to go with 373 one day after all the above are done.
