Well the main thing about that build is that it would give good N/A power/torque, similar numbers to the 20v's without too much trouble, BUT the it'd be WAY easier to find a 7afe in my area than it would be to find a 20v or 4agze, or 3sgte or any other engine that could be swapped in.
Just kinda food for thought, right now my mr2 is my dd, so doing a build like that may be a bit tough
especially being i'd want to keep my newly rebuild/reconditioned and ported head (that is currently on my engine) to use on that kind of build. And as of right now i have to work out of town so i have less time to work on it.
