good point, and just to agree- the weight difference is minimal... something like 40 lbs- take a good shit, and there goes most of it.

the main benefit to all of this is, you can get d series mounts pretty cheap from jdmshit.com, and have 220 off the bat, which should be plenty for your purposes. with a little work, they take just fine to low pressure boost, and if built/sleeved, they can handle quite a bit. or, you can always throw in some higher compression pistons, and build the head for more power. check out www.hmotorsonline.com for a motor, and specs/information.
