The million dollar question? So is the VH45DE motor infact a better motor then the early model 1uz-fe's? For starters the VH45DE is larger motor, has more power at stock, appears to be stout, alluminum block too.....Hmmm? Longevity is the big question mark...As we know the 1uz-fe's can go 300,000 miles when serviced and maybe even more...Also the early model 1uzfe's can handle as much as 500whp with stock internals, can a stock VH45DE do that? Probably not is my guess...
I still have to give the edge to the early model 1uzfe's after all is said and done as they are cheaper to buy used...
