Engineering Explained always has good, informative videos. Here he didnā€™t touch on the integrated exhaust manifold on this version of the engine, however. Itā€™s pros and cons compared to traditional exhaust ports with a separate exhaust manifold.

Whatā€™s interesting though is the promo video during unveil didnā€™t show the engine having integrated exhaust ports. Looks like split port manifold:

If you look closely, the blue diagram is just showing the internal ports that are cast into the head. In the video, you can see that the turbo bolts right to the head.

I'm sure that is the case, but...I don't see that. Oh well...still not interested in the initial cars. Show me the good stuff.

High CR is actually the way to go for high HP....especially with ethanol and forged components in the picture. Alot of 2JZ folks go 10:1 CR on their builds and it does well with spooling and low end grunt. No worries here with high CR honestly.
