i'm gonna keep this short n sweet
7m = 45 years old and a glorifed 2ltr na
1jz = 2.5ltr (not 3 hehe) built as a turbo engine, mhg, hyperteustic (sp?) pistons (stronger than normal) and loves to rev
7m = great engine when built correctly but lacks 50hp in comparison to 1jz
both make power easy when built
1jz = tough off the shelf items (some are swappable with 2jz)
7m = parts EVERYWHERE
1jz = costs heaps to get shipped + installed + running
7m = use what it'd cost to do 1jz and you'd have a mean 7m
at the end of the day it's all up to you
