Just wanting to know if 2jz pulleys are interchangeable with the 1jz ? As I have a link below for some aftermarket pulleys that I would be interested in buying if there is differences in our pulleys.

balancer fitted. P/s exact the same water pump the same as long as not running aristo setup. Alt the same.
Just be careful when you install the cheaper stuff. Alot of them the belts dont sit right and wear out quick and some are not in line so wear the belt aswell

i got that pulley kit mike but i made the mistake of finding the one that had the crank pulley included haha everything fits and looks mint you wont regret it

Thanks Prashant ! So you've had no problems with them ? I changed just the crank pulley on my old 300ZX & that made a good difference, did you find any acceleration differences fitting this light weight pulley kit ?

the only thing you have to be careful with is alot of ebay balancers... well arent balancers. they are basically a crank pulley. they will be lighter but will offer no dampening of any harmonics from the crankshaft.. one way to think is the engine will be like a wheel that is out of balance. something you dont want at higher rpm.

Never, ever run those after market 'balancer' pulleys. The harmonic balancer is there to ensure that any torsional vibrations from the combustion process are absorbed by the balancer. Torsional vibration can fatigue fracture crank shafts and cause engine balance issues at certain RPM levels where the stresses on the crank are higher due to harmonics.
In addition the 2JZ GE out of the GS300 and Supra have a bi metal aluminium and steel balancer presumably to reduce weight and have better damping from the steel's inertia.
After market balancers such as that from ATI, offer better damping than the stock unit and do not break under high RPM. Always run a harmonic balancer and not a pulley with no damping effects to keep your engine happy
