Prices are "ballpark guesses" and can obviously vary quite a bit, but I came in right on budget with my swap (#4) - saved some money where I thought I'd spend some (crossmember, driveshaft, flywheel), and spent some where I didn't really have to (ie. shifter, hydraulics etc.). The inability to find a T56 locally, the high cost to ship one, and the added cost of mating one with a 2pc rear main seal engine is what helped me decide on a T5 (for now at least
😀 ).
