instead of going 4500 on the hi boost go with the spool stage 2 kit which is all you need really for some boosted fun and then you should have enough money to get the C/F hood or other shows things you may want to do.
or since it is for show get the stage2 kit and then chrome/powdercoat/anodize all the parts you want from the kit so it looks really really good as well as puts a grin on your face while driving
