for the custom fab work to get it all in the car and working you could just do a boosted B-series and make a lot more power with less hassle.

engine swaps like that just don't work well unless you plan on making your own everything and it's solely a race car. you'd likely need to run a full set of aftermarket gauges due to the nissan ECU/sensors not working with the honda stuff, of course the custom work to get the engine even in the car (plenty of relocation and cutting/welding/fabrication), i'm sure custom axles, custom exhaust, a whole lot of time with wiring diagrams trying to make various functions work, etc. when you're done you have a stock ass motor in the car with no extras.

of course it'll go in the 200sx, it's the same engine platform as the pulsar so it's a bolt-in affair on that car.
