I have been thinking of doin a motor swap on a 1971 240z. Which motor is the lightest out of the RB20, RB25, and the RB26? Which one has the most hp? I am lookin for specs and numbers. :screwy: :confused:

I have not weighed my RB26 that is in my garage, but its very heavy, say in the 475-500 range.

Most hp, I think you know that anwser:)
