I was looking over this again today and I don't think I'd choose anything but a stock cam and exhaust upgrade on the 20r unless I was building the 20r/22r hybrid.  Then I think I'd Glen it up with the big nasty LC cam since we have video proof of his truck accelerating like a Celica.

The 261C look pretty good on it but the stock cam still kind of smokes it in the drivability area looking at the curve.  Funny how that smaller displacement and different head change how it responds to a cam upgrade.  I wouldn't have thought it would be much different than the 22r.

Yes, its interesting to see what changes do, at least what the calculated data shows.

It also confirms what I've believed for many years that the Japanese auto engineers are a lot smarter than some people give them credit.  Of course the auto manufacturers are bound by the our EPA laws, etc. Considering that other countries may have different environmental laws regardng automobiles, Toyota does a pretty good job at developing highly marketable engines and vehicles.

Gnarls.
