nissan R390 Le Mans racer. go to the R390 forums to see pics of it.
i personally think it would take more money then it's worth to shove a VK in a 240SX. but then, that's because i'm a huge anti-fan of drag racing, which is pretty much all the car would be good for with a VK in it. now if you were drag racing, then it would probably be worth it. but for drifting/SCCA/anything else that utilizes the car's handling, you'd be screwed with a big ol' V8 up there. i'd rather have an RB26DETT, which (according to alot of people) ACTUALLY makes around 320hp from the factory instead of the 280 that Nissan says it makes in order to slip under the self-imposed Japanese HP restriction.
