First of all you can get different rails for the car, depending on what injectors you have. Contact Mr. Allnet for details. It wasn't very hard to put together, but It did take a lot of time preparing the pieces (hoses & fittings) so it was just right and it went together. Remember- trhis is a FUEL distribution system, and it's under HIGH PRESSURE, so it needs to be done right. Pallnet can get you all the fittings that go on the rail, but you might need some others to hook it up to the car, and some pieces you need to get yourself.Mr. Allnet can help you with that. Assembling the rail takes some time to do it right (injector barbs, pressure gauge, in & outlet), then you can mount it to the engine. You get brackets to support the rail. I used short hoses which were stiff enough to support the rail, so I don't have the brackets on (yet). Then you plumb in the fuel supply & return lines, and maybe some fancy pieces. I just had the engine tuned to specs by a Nissan tech, so I'm getting double the MPG of before ( very detuned/less MPG) but I don't feel any more performance, since the limiting factors are the injectors, pistons, valves (rest of the engine). thx
