It has come to my attention that many folks are using Japanese imported engines in their builds. This is fine except a very small number of these engines VZ and MZ apparently have a different crank. Or at a minimum the crank is machined differently. The problem occurs when a manual transmission is mated to the engine. There is no relief machined in the end of the crank to accept the MT input shaft.
The number of these incompatible engines is very low. Maybe less than 10% but DOUBLE TRIPPLE check that your crank is compatible BEFORE bolting the transmission on!
So far this applies to 3VZ, 5VZ and possibly 1MZ engines. Again CHECK YOURS BEFORE BOLTING ON THE M/T TRANSMISSION!
Pictures follow of NAracers incompatible crank:
This is how thre recess SHOULD look.
