:aigo: i think the 1jz is a great engine for autocross quick runs iv'e been looking at the 1jz's for some time and it sounds like a good idea. The reason im going 1jz if i rebuild my na/7m it would be good in numbers but i wan't to have some suport on the bottom end. don't get me wrong as much money i would have to put in makeing a good 600hp 7m i would or could have a 800hp fully built 1jz but right know i have 2 na 7m's one is being rebuilt the others is going 7mge-T is this a good choice?????????? meaning getting the 1jz
