The answer to this question is in dispute. Some people say the 4AGZ pistons will clear the valves, others say they won't. I personally think they will clear, but will also negate the non-interference design of the engine. Maybe you can get the 5 valve flycuts cut into the 4AGZ piston...richdan said:i just want to know if i can use the piston from 4agze to my 20v to lower the comp..?i'm planing to put a turbo on my 20v..\
It'll fit on the rod no problems... but the problem we mentioned above is still of concern.richdan said:no i'm just using the pisto but i dont know if the 4agze piston will fit the 20v connecting rod..?
what do u guys think is it posible to use it in a 20 v engine..?
