why only compare the 2jz and rb26? what about the l28et the 1jz rb25det rb30et and the rb30det-hybrid since its been said that the "rb30det" is has the most potential and reliability of handling big numbers now as of the arguement if its easier to make 1000+hp with a 2jz its obviously a good motor and one of the best choices if you own a toyota or lexus but if you own a nissan leave it to the rb series or the l28et if you own a datsun as for whats better i love the rb series motor because im a nissan fan but i love to see 2jz stuffed in just about anything also.
