In my opinion it's best to achieve the 500+ hp in a regular C4. It's cheaper, and easier to work on, and when it's time to sell, it's easier to sell a modded regular C4 over a ZR-1".
I posted on another forum i belong to. dometicmisfits.net
the above mentioned quote..was from a guy we call numbers guy,
he seems very knowlegable about cars...and owns quite a few it seems..but...when i posted the question to the forum there..about some upcoming mods..i have been thinking about...he anwsered with the above quote...my question is
Is this possible?? with just bolt on's? cause i have headers...and corsa exhaust..and i only have 353 rwhp...before the corsa.
when i dyno'd in may...i was wondering...whatcha think?

When I purchased my car in April 2003 topend port work had already been done and it had SW headers/no cats going through a stock exhaust. The car dynoed 377 at the wheels with this set up. Two years ago I added a B&B exhaust and RT cats. I did not dyno the car after adding the exhaust but seat of the pants feel was that it had more power. The car is currently at EES getting upgraded to a 402.
Clearly, 8388's car possesses the most RWHP for a stock set up most of us have heard of. That said, for the vast majority of our cars the only way to get near 400 RWHP is to add a ported topend to headers and exhuast, and to get substantially over that figure you're going to have to port/polish the heads as well.
As far as the LT5 being too complicated for internal mods, I disagree. To be sure, you can't run down to the local speed shop and get the car fitted with off the shelf turbos and superchargers, but there are a few very good tuners who can put some serious bite in the beast if you choose to go that route. And even though one can certainly obtain 500 RWHP for much less on an LSX engine, those engines are simply nowhere near as exotic as the LT5 and in my opinion lack a level of "sex appeal".
