im used to working on and driving high horse/ high torque cars. the 1jz is proven time and time again (just like the 2jz) to produce mass amounts of power with very little effort. there is nothing wrong with my l28. i just want something that i know just a little more about. about the 2 options, ive seen rb25 swapped zs. they are absolutely amazing. ive seen very few 1jz swapped zs. they are equally as amazing if not more. ive always thought about what other motor i could swap into it. now that i have moved back from new orleans, i have the opportunity to do so. thats pretty much it.
