http://www.cardomain.com/ride/804063 Gives a pic of a 4AGEs engine which states

"The individual throttle bodies look like they came off the fabulous 503 race engines. Think about it, no Toyota factory RACE Engine had 5 valves per cylinder!! Yamaha- who works with Toyota on cylinder head design (and manufacturing), have been a very avid pioneer and supporter of the 5-valve design. The short-lived Yamaha Formula 1 engines had 5 valves per cylinder. In terms of maximum valve to surface area- the 5 valve design cannot be beat- theoretically and geometrically."

"Well yamaha made the head for the 3SGTE and that is one of the most reliable and powerful engine toyota has ever made. including the 503 race engine they used in the 800-1000HP IMSA GTP cars."

"on the topic of the TRD 503E 3SGTE engine.
its what Rod Milen uses for his 1000HP Celica at pines peak.
the 503E is a pure bred racing engine which has absolutely nothing to do with the 3S-GTE. there is only about 5 - 10 503E's in the world.
Rod Millen has at least 90% of them.
im sure you could buy one if you called Toyota Team Europe in Germany and asked them to make you one."

*Runs off to check 503e pictures

First I've heard of a reversed cylinder head!

Oddly enough there was a brief picture of one on SKY today when they had a quick run round said Rod Millen Pikes peak celica on "Rides" (I think). It was something to do with his son Rhys buildind a car

I've seen that engine a couple of times in the past on eBay

$4k seems like a lot of money for <1000 miles of motoring which is, I guess, why it's never run in a car

Nice looking dry sump kit though
