If you really expect anything significantly beyond that you're just kidding yourself and should be getting a pushrod V8 (read: LS series) instead.

This. I think it's enrealistic for any N/A car for that matter. I too sold my Z with every bolt on and putting down 315 rwhp seemed pretty good for what it was. In fact it was a big improvement especially with a tune and improved throttle response. (of course having coilovers spec'd up nice n tight made it feel much snappier)

I'm in an M3 now and it's the same story. I'm not going to get much more than about the same gains (as the Z) with bolt on's. It is starting from a much stronger point but the overall gain at the end of the day is probably equal (+50 hp) with full bolt ons. I won't lie... it's a different car alright but you know, that comes at a co$t.

I miss my Z for what it was and would absolutely recommend one to anybody. It's still the most bang for the buck although it's getting some pretty stiff competition coming out.

Even with the 5.0s. We can get to 440whp or so with intake, tune, and full exhaust. Beyond that you need FI. Unless you are OK with shelling out several thousand bucks for cams (510whp), but FI is the best bang for the buck without a doubt. I think that's true for all cars. If you want cost-effective power, go FI. Otherwise realize that bolt-on gains will be limited.

Yeah the upper limit of my car seems to be around 400 whp with everything short of FI from what I've seen. (this coming from a 4.0 V8)

Of course I could always get one of THESE to the tune of $26k
