You're funny. You think an NA with 200hp is going to be as reliable as a turbo with 200hp? Not even close. It's been said many times before, but I'll say it again. For 2-3k, you want to just sell your NA and buy a turbo. The only difference between a turbo and an NA in the Z31 is the compression (because of the pistons) and the addition of the turbo. And the idle control stuff. Beyond that, the turbo and NA blocks, heads, cams, intake, etc are all exactly the same.
For $2-3k, you'll be lucky to see 180hp at the rear wheels. Different air filter, better exhaust, cams, port & polish might get you there, but it will be a stretch. In the mean time, the same $2-3k spent on a stock turbo will put you at 250-270 rwhp and be just as reliable.
If you're thinking of building a motor, build a turbo motor. Keep in mind, the farther from stock you go, the less reliable it will be. It's up to you to decide how much less reliable you want to go.
