2zz Motor Views
I've seen quite a few of those engines in used Celica GTS/Corolla XRS that had sloppy crossover on the lift profiles after only 80K-100K. However, I've seen many B18 and K20 Honda revers that seem to be just as happy as new, even with high miles.I'm not saying that the 2ZZ isn't a good motor and that there aren't good high mileage examples out there, but I haven't bumped into that many.I'm thinking that Lotus is going to another brand for their latest powertrain.
I had a 2000 celica gt-s. They had some crappy lift bolts that were eventually redesigned around 03. Litteraly like a 1.50 part. My 2zz ran strong until 09 when I sold it with around 190k miles. Admittedly Honda had a more mature and probably more reliable engine with the b and k series motors. However I'd take the chasis of the 7th gen celica over anything honda made for the US during that time period.
I'll always remember the 2ZZ as the only motor out there (in your typical US production car) that was as peaky as anything that came out of Honda, something I never thought would happen. I mean, yeah the point of these motors is to rev the snot out of them with a huge grin on your face, but 133 lb-ft @ 6800 is seriously lacking. The idea of peak torque occurring at almost 7000 rpm (where most cars' redline is) is hilarious. Still, it was a great motor from Toyota and I doubt they'll ever make another one like it.
All plugs to the ECM have been removed including the four wires that are necessary to integrate to the body harness if you are running a 2zz motor in your Spyder. These wires have to do with the O2 sensor if you’re curious because the Celica GTS keeps its O2 sensor so far away from the engine that it is wired in with the body harness. There are three plugs to the right of the two wiring bundles pictured that must also be removed. They come out with the engine wiring harness.
