like i said i want to be different and not do what everyone and their mom has in their toys. i dont see why it would be a bad choice if that jake hollenbeck guy put one in that buggy. and last time i check rock crawlers crawl unless he rock races the thing..im just going to research more and ask on some RX-7 boards to see what a 13B turbo will run, im guessing a fair chunk of change. but the best part is i would have the fastest toy around here 8)
