Stroker kits for the 2ZZ dont make as much as a S/C. What they do make is way more low end torque, but you cant rev them as hard. Stroker + Turbo is king.3ZZ stroker kit would be good in a sportivo tho, cheaper then S/C cause you'd need custom stuff, custom bonnet most likely too, I dont think it'd clear it. I still wonder where people get the 3ZZ name from? The 3ZZ-FE is a 1.6L Engine in Corolla's in Europe. Anyway, we have a stroked 2L Sportivo, and it revs its tits off. Not sure what you meant when you said it doesnt rev as hard. By the way this is running a real ECU though From the ones ive seen on the net, they cant rev them as high as a built non-stroker, thats all I meant. Yeah 3ZZ is from the Trial kit.
