No way man, I am going all out. 800hp+ Although I am thinking of using a 3UZ block and boring it out and using a 2UZ crank, and use either 3UZ or 2UZ heads. I am pretty sure AEM supports VVTI for the 3UZ heads. So I guess after that, you really couldn't consider it a 1UZ anymore, but for starters, I will just do a plain jane 1UZ.
