Ok got another question, sorry if it has been asked before. Is a 3MZ just an over bored 1MZ with VVTi?
After taking my 1MZ apart it looks like there is plenty of room to overbore, does Wiseco or anyone piston manufacturer make a drop in over sized piston?
the 1MZ is an 87.5mm bore and the 3MZ is a 92mm bore. both have an 83mm stroke. that being said it wouldn't surprise me if the crankshafts are the same and the rods are the same. I have a good contact at Diamond Pistons. I have built several 2ZZ-GE engines with them with great results. Is there a demand for an over sized piston?
