$50k? Not unless MoTEC has never done VANOS or something. As long as your basic hardware is supported out of the box, you can be in MoTEC for $15-20k. That's assuming you're having a reputable engine builder do it who is putting your engine on a dyno anyway, which you'd want to do to get a reasonable intake and exhaust anyway. Heck, it might be as much as $25k on something more exotic, I guess. But it shouldn't be $50k.
