So I wound up selling the Emanage, just didn't need it right now. Running the blacktop head on the silvertop block with a 5-spd LSD tranny and threw in a .8mm TRD headgasket. Couldn't drive it for a while due to a leak at the rear water inlet caused by a creased gasket, which I flattened and used sealant to close off. Also the VVT Solenoid on the front of the head got bent during the swap, so I had to wait on a new one. Now that I'm driving it, the exhaust sounds deeper than before which is much appreciated. But as always theres a down side. The water pump on the new block is dead, and I can't use my old one off the blacktop so now I have to wait for a new one and who knows how long that'll take to find. I can still drive it short distances, about 10 miles before I worry about the temp, so I not totally SOL for the time being. The wheel on the pump sounds like a damn supercharger when I hit wide open throttle, and the radiator got pretty hot(about blinded me when I released the pressure on the cap).

Why can't you use your old pump? The pump itself is the same throughout the 4AG, it's just the back half that is different(according to members on MR2OC). 16100-19245 is the part number for a silvertop pump.

Glad to see an update though :D

Because the timing belt tension is a spring on the silvertop block and a piston style tensioner on the blacktop block. It interferes when mounting the blacktop pump onto a silvertop block, I already tried back when I had the engine out, it sucks. Thanks for the part # but I already have all that info, it's actually sourcing out a new one that gets tough. I go through Cabe Toyota in Long Beach for that kind of stuff, hopefully they have one in stock, otherwise it's gonna be a long wait.

Ah, that sucks man. Hope you can get a new one soon.

I'm being told over on club4ag.com that with very little grind work on the housing it'll fit. So I guess I'll find out whenever I can find somewhere to swap the pump out, moved to my inlaws and I can't do it there due to their driveway being at an incline. How incredibly arduous, F me in the goat ass.
