Yes, I should have stated 'B'HP. My mistake, sorry to mix things up. The book here states the Kw output of all markets of the 260 being 123. Also an equal rating for PS. However, BHP is what changes between the markets. Could this be explained by the shift of manufacturers advertising cars with net horsepower ratings instead of gross HP? Was it the only the US that had only shifted to this rating system at the time? And where would this power have been lost? Obviously some variations between markets point to the flat-top hitachi carbs, emissions equipment, and overall weight of the car being moved. But could the compression ratio or ignition timing changes hinder an American market car compared to other market 260Zs, or would these alterations to run unleaded petrol have been universal? Just really curious as to why the US 260z are so undesirable and viewed as weak. I am just looking to make the most of the L26's potential and have been confused by all the scattered and varying information about the car and its setup.

My question that I've been researching is what differences are there that make a 1974 260z (mine is early) different from the European 260 in terms of its motor? I know that from a broad view the key differences are the reduced compression (from the altered '74 E88 head?) and flat top emissions-grade carbs, but what changes were there from the 139hp motor to the hotter 165hp?My goal, if possible, is to take my stock motor and convert it to match or exceed a euro-spec engine in terms of performance. See how far I can push an L26 without swapping or making a 2.4 or 2.8 motor. Any help or info on the subject would be very much appreciated
