Honestly I would go with option A. So many people buy stuff to get some quick power only to turn around and sell it for super cheap because no one wants really wants it. If you wanted the evo, you could probably take your time and find it online used. It's the same thing only much cheaper. As for gauges, that's a decent price. I got a two-pod pillar with Autometer Phantom II EGT and boost gauges on e-bay for 215 shipped. IMO mechanical gauges are the best. My best advice is take your time!!!! Don't get in a big rush you could save a lot of money with a lot of patience.
