in 25 words or less. tell us, the many 3vz-e owners, what MUST be done to it to get that 30+ hp gain...
btw, it must be CARB legal...
one dude on yotatech is claiming he can change the top end using camry v6 parts and keeping the bottom end.
>>>*...*Uhhhh...*LOL**...K....dang. (I can't drink a cup of coffee in 25 words or less...)
"*Red button on dash"...(That's just four words but it works...)
Seriously, my personal feelings are that this engine design came out to be a bit breathy for the Toyota folks. They simply backed it up 20-30 plus ponies when they tried to increase the low end power.
Ford did that back in the early 70's, there are other examples. Factories do take shortcut$$$ when dollars are involved..
I concede, it is what I think, for what that is worth. Over and over I hear the reports of freeing up the exhaust and losing low and midrange pulling power.
So bigger valves, some port work, free exhaust, yep, I see 30 ponies. Soften low end? Yep, that too.
Like I said, I am interested too. So this is all just an opinion of a 61 year old coot that has been doing engines for 40 years, with no real actual test history on the 3V to back up the best guess. To top it off I am sitting at my kitchen table in my underwear at 5:30 in the morning as I type this. So don't look at me to be no Expert, I just poke sticks at stuff to see what happens. It just looks like fun to me to try and make something a bit better..
On changing the heads to the 24V, yep. Need the Camry pistons, though..(*Valves kinda run into things otherwise) .But why bother? Just go get a Camry engine...same thing, even to the bearings and rings...*EB
*Beats the he** outa me!....*LOL**...
