thats the toyota qouted ratings...but i think logie was saying he was not after power,so that woulld be more than adequate...for the price of a soarer box i would be inclined to use it and just change if you broke it(which i would dought)as they are only like 100.00 fpr another...my opinion is the 1uz v8 swops are over thought,its a 1uz v8 its nippy and you get the v8 sound,but you need to spend loads of money to get good power to equal any 2jz tt,its just a cheaper option to a bpu 2jz tt swop...buy an engine and box for 400.00 bolt it in and get it wired for 300.00,and then have some fun...this swop if you do yourself should be easily done for 1k...
