but like you said, stocks are good anyway..
im looking into a forged one with a different stroke pattern
or even if the 1jz crank will fit in a 7m..
i personally want torque and horseys..
and a longer piston stroke would be a great start(along with my engine rebuild)
like you said..
DREAMS...love em too

i may not be looking at it right(or it may be the fact that i dont even know what a supra harmonic balancer looks like) but isnt this way to big?

Hi!
The harmonic balancer is the rubber centred pulley at the front of the crankshaft and this thing drives all of the accessories ( alternater, water pump etc. , The reason it is rubber centred ( the pulley part is not directly connected to the crankshaft ) is because , unlike the 4 cylinder engine, the 6 cylinder in-line engine creates it's own self destruct vibrations at high engine revolutions and fitting a solid pulley would not dampen these unwanted vibrations and the engine starts vibrating at high RPM usually resulting in early engine failure , usually a sheared crankshaft.
Judging by the number of threads complaining of theirs coming loose , I would say they are essential and need to be monitered for tightness on the crankshaft.
This is what they taught me at college , many ,many moons ago!
