seems a bit expensive. what 4age is it? when you say "everything to drop it into a ke70" : does he include tailshaft, mounts, cross member, fuel pump etc.
to make up $2000 you could pay:
gearbox: $700
computer/loom: $400 (what SSS automotive charged for a loom and ECU)
complete motor: $900
if it just includes these bits it seems expensive but it could all be really good stuff.
if it has EVERYTHING you need for the conversion then its an ok price, considering it would all just bolt in.
