The closest I can see, the block and head are 4AGE, but the valve covers aren't what I'm used to. Could be a more recent, non-US flavor of the AGE. Also, that intake is totally not what I expect either... I mean, does the air come from the bottom ?
The ports, intake and exhaust, look like a racing 4AGE, square port without the TVIS, and the round exhaust. The girdles look 4AGE, and the oil pump. But that's the end of that.
Also, the distributor isn't like any 4AGE I've seen either, or Toyota for that matter.
