ARP does now have a part listed for the 2zz motor. It is 103-2802. Seems the only difference between the 103 and 203 bolts is that the 203s are slightly longer. BOE sells the 203s for the 2zz to allow for the extra thickness of aluminum flywheels. So long as there is enough clearance on the back side they can be used with any flywheel. Monkeywrench Racing has ARP make flywheel bolts for them that are slightly longer than the 103s so it sounds like they are pretty much the same as the 203s. Monkeywrench does specify that the flywheel bolts should be installed with Locktite on the threads and lube on the back side of the head. That the torque should NOT be done per factory specs, but rather to 70 ft-lb and that they should not be turned an additional 90 deg as some instructions indicate.
