After breaking down the Nvision I was super surpised also its one of the best engines @ idle Ive owned. Im not saying the B2 isnt a great engine probably is but if someone would ask I would say get the Nvision if the price was normal meaning no discount then thats a different story.
i owned the Nvision 521R just 2 weeks ago. i admit it does have more power than the b5 in mid and high but imo not the low. i had nothing but problems tuning the nvision, it was rediculus.i got one that i had to install the button and ls needle from amain. i couldnt get it to run under 270 degrees and usually wanted to go at around 285! i raced a b5 with it and took him off the line but the b5 was still slightly rich. i think its compareable to the b5, with a slightly faster spin up speed. (which i think was its best feature) the fuel economy was atrocious though! i wish i would of got a werks in the first place over the nvision. so far the b2 has never got over 230 degrees. cooler running motors last longer in my book. The head size on the werks motors are considerably larger than the nvision as well
