Toyota 2TG Engine – Balanced and Blueprinted? Stroked?
My FB experts tell me that the pistons likely put the compression ratio in the 10.0 to 10.5:1 range. I flip the engine over and discover that material has been removed from the bottom of 3 out of 4 pistons and from both ends of all four rods. This thing has been balanced. This is quickly getting interesting.
I also notice the block has been clearanced for the rod caps/bolts.
So I grab my calipers and do a quick/dirty stroke and bore measurement.
This thing ALREADY has the 78mm crank in it!
Just keeps getting better. The blocks have a ton of meat in them – it’s been fitted with 89mm pistons. 89mm bore x 78mm stroke is 1941cc. Almost a 2.0L – It’s the dream motor for this head! So the racer not only had a head which they disallowed the next week – he was sporting 1941cc’s when he should have been limited to 1588cc’s (85mm x 70mm). The Holy Grail indeed!
