oil pump, oil filter setup, n/a has 1 knock sensor turbo has two, almost all the other sensors and eletronics are different (afm, ISC, etc), pistons (that's the compression difference), spark plugs and wires, alternator, rear diff, driveshaft, clutch, intake setup, radiator (according to Toyota anyway), clutch fan, and I think I'll stop my ramblings there.
It is, but in this case it's MUCH more common to break stuff if you turbo the N/A Motor. It doesn't have the internals to keep pistons cool under boost. It's just generally not designed for boost. Save yourself the trouble and pick up a 7M-GTE from http://www.nippon-motors.com or someplace like it.toyotafan said:all right ..... oil lines can be delt with by using a remote oil filter..
compression on the other hand ..... i thought more was better?
