Imho the 2zz is old technology, it wasnt bad and for the time it was a performance engine from Toyota (read: Yamaha) who really wasnt putting out much in that department. But those hp numbers are at the crank so it's comparing apples to oranges. A 2zr with high compression, cams and a high rev range should be able to easily match the 2zz but in a package that is already in my car and not a whole different swap.

If I was going to go to that trouble and cost I'd go with a Honda K24. 220whp NA all day. The point of where I'm going with this build over the next few years is one that you don't have to pay a shop to fabricate engine mounts and other completely custom stuff. I want to show people that they can buy a 12 year old 2nd gen yaris for cheap, gut it and do an engine swap and with bolt ons, achieve a lightweight fairly fast track car

Ah, all makes sense to me. I wasn't aware that the 2ZR could produce that power. The cams sound really promising. I did read that the 2ZZ has similar power output up to ~6500 RPM, then it comes on a lot stronger. Very informative stuff. Thanks.
