I actually just finished installing my fmax kit on my 98, it's been sitting in my floor for almost a year. I am enjoying it so far, I have a few things to iron out. The only thing I dislike is the stalling issue, many people with ka turbos have it and it doesn't look like I am going to escape it either.

Future plans: nissan motorsports cams, hks ignition, larger turbo. (currently a t3/t04b h-3 trim stage 3 wheel with a .48 a/r at .65 bar, great for driveability but I would like to make the most hp a can at 1 bar on the stock motor)
