ok so i have driven a few 1JZs and aort from all hte other good things aobut them, they are economical when cruzing.

So i was wondering are the Nissan negings the same?

I have asked this questing in hte toyota forums and, surprise they said 1JZ was best (and 2 J) and of course in the nissan forums they say theirs is best.

so i thought i might get an unbiased answer here :-)

Most economical at fuel consumption?

or

The engine that can hold the most power stock..... or the engine which requires minimal mods to produce a consistant amount of power for a daily driven reliable car...

i think stock sr20 would be most economical

rb30 would be last i'd say just because its the biggest and the oldest.. and also because in stock form they have no cooler and are set up to run really rich so that the excess fuel actually cools the pistons..
