Found these pictures on my computer and thought I'd share them. A custom built engine built by RS Yasu Japan, dubbed 4.5A-GE or 4.5A-G as seen above. Can't quite remember the specifics so don't quote me, but I'm pretty sure it's a 4A-GE head and pistons combined with a 7A-FE bottom end and crank to make a 1.7L engine. It was mainly used for circuit racing in Japan in AE86s like the Levin above. The combination is something to to with upping the torque without boring the 4A-GE block and losing the revviness of the 1.6L, but again don't quote me.
