I tried to contact this company about a turbo kit that they offer for the SR20DE in the Sentra, but they said that they won't guarantee that it will fit in my 1999 G20. Has anyone ever put this package on a P11? The link is http://lion.esosoft.net/hotshot.com/products_turbos.htm If so, can you say how diffiucult it was to put it on? It seems like in the cars that it was developed for it was almost a "bolt-on" according to their website. I could probably make it fit, but I don't want to do a chop job on my car. I would rather use a sort of "end to end" solution that was designed to work as a total package rather than a patchwork of a bunch of different componenets. I really don't want to buy something that has been used and abused by someone other than me. Or something that I have to make too many radicalchanges to the car to get it to fit. I think that this turbo kit looks like it is pretty well thought out and comes with basically everything that I would need, which is why I am interested in it.
