New engine variant. The TU was the updated engine they put in the supra.
It has:
-a split cooling system with 2 water pumps and a pressure releif valve on both
-1 peice timing chain, as opposed to 2
-Updated Vanos gears
-New fueling including the pump that is a decent upgrade path for the B58B30M0/M1/C/O1 engines (prior to technical update)
-Lighter crankshaft
-Cylinder head/exhaust manifold integration
