turbo guys are taking this discussion as a personal attack at their modifications (which is not the intent) when you forget that the original point was to make a reliable 800 hp (not 500 which is attainable via several kits here, we know, for about $15-20k) car for street racing, of all things, under a certain budget while maintaining or increasing the value of the car over time and all that after driving the car twice. you all know that all these points cannot be accomplished simultaneously nor they should be for the perceived purpose he stated. i have respect fot 03s2k for being level headed and explaining few things, maybe his street racing comment wasn't what he meant, neverless his goals far exceed what most FI guys here accomplished. these discussions are worthless as each reply is taken out of context and taken as 'hollier than thou' attitude instead of 'think about it some more' .
after all this there is only one personal point i'd like to make, holly or not- no matter how much money you throw at this car (remember he wan't to sell the m3 as it is dropping in value- so the nsx is somewhat an investment) to make it fast in 1/4 mile, all it will take is a snot nosed kid in a beat-up 5.0 mustang with $5k engine to put it all to rest. all of you know this.
forgive me, thats just my 'internet opinion' i learned here in the last 5 minutes.

Just like any thread, topic, or forum, prople will take comments as personal attacks. Misinterpretation is part of the means of communication. Like I said earlier, it would be better to ask those who have been there and done that than talk to people who have no FI experience or experience at said power level. In addition to my last post, there is a difference between pulling 600whp once compared to continuously running at that level.
I don't recall any thread where the negative comments of people changed the mind of someone who wanted to street race. I find those comments more of a vent of anger than affective at changing the outlook of that person. If someone is going to street race or do anything for that matter, I don't believe a complete stranger has any impact on that.
It is pretty understood at what it takes to make 4-500whp. Can be done by said tubo kits and has been done often on stock motors. Make sure the tuner knows what he's doing because a bad tuner can grenade any motor and the NSX motor has its quirks and you dint want someone to 'learn' on your dollar.
OP: for your street/drag application, you can run 4-500whp, meth, or whatever you want and be fine for a while. Keep in mind the demands are much lower on a daily driver with occasional short bursts a few times a day or less than continuous beating on it and 'boosting' when you are driving it. If you will rarely get on it, it will last longer.
As far as prices go, I didn't see labor rates calculated in there for pulling a motor (pricey), for a standalone ecu, bigger injectors, intercooler, larger fuel pump, or many other components.
Making 800whp reliably is pretty darn pricey. Sure those M3s have a dynoqueen number that looks amazing, but its a similar situation that you find in the nsx, it won't last. You can throw a big laggy turbo on anything with LC pistons, ice the IC and lay down a good number. That's far different than actually running at that level. If you want a narrow powerband like a supra, throw a huge turbo on it, and if that's what you want, don't let anyone stop you.
Doing the motor properly is expensive, from a billet crank with larger rod journals to handle the power, to forged pistons and rods, to billet main caps and oil pump, valves, springs and retainers, fuel injectors and pump, air/water inter and aftercooler, tank, pump, clutch, and much more.
You can always email me to get a price quote on the components we run in our Time Attack race NSX and what it takes to attain your goals.
Also keep in mind you always end up spending A LOT more on any car project than you originally intend. But you can reduce/eliminate huge mistakes by learning more upfront from those who already accomplished what you are looking to do.
