I just stated I would try it on a GE motor in my garage. So before you come hijack my thread keep to your own business. I think you have an IS that needs some work. Whats it been 4 yrs in the making for a GTE bottom end IS300....I'm not going to sell it to someone with a GE motor if it does not fit. I want to see for myself that it does not fit. Like I SAID BEFORE I will take a look at the one in my garage.
