I'm really surprised that someone hasn't done this.....
I'm talking about a serious N/A build-up with high compression forged internals, cams, lighter valvetrain components, etc. I know it's much more economical to go FI, but I'm really surprised that we haven't really heard about at least somebody doing this

yeah to much money for nothing but a hi rev...........def not worth it
Turbo is where the Powers at
but yeah a 8k redline would sound wicked down the straights
I also have a bud who is running a n/a set up on his z for raceing)

we shall see how it turns out soon!
As I said before, in australia, we all have around 20 to 25% drivetrain loss on most of the dyno machines we use down here, and my baseline is around 220rwHP (with crawford cats, nismo flywheel, nismo exhaust, air filter, lightweight pulley)... and that 220rwHP still gives me JUST slightly more than 280HP at the engine (since those exhaust systems just FREE up HP, they don't create HP). And with the new N/A setup that I am going to run, I am expecting to get 70rwHP in gain and I think that's actually quite a lot for a N/A tuning already though... If I calculate correctly, with 290rwHP on aussie dyno machine, we might be looking around around 362HP or more @ the engine since a stock Ferrari 355 pulls out 279rwHP on the same dyno machine that I am using and it produces 380HP at the engine... my calculation is being at the conservative side, don't wanna disappoint myself though...
cheers,

This will prompt some flames, but..
You could swap an SR20 in and make the same power, easily more if you wanted, and save 200lbs off the front end of the vehicle. Even if you make 320hp at the wheel, you've caught up to an entry level supercharger system on power, and lighter than a boosted VQ would be, but a SR would make that without flinching and have plenty of room for more with a substantial weight reduction.
Now, having said that, I say go for it, and as i posted in Richie's other thread, rev the **** out of this motor and let us all know how it sounds. The respect for putting down over 300whp NA would probably be worth it, and the sound to die for at a track as it goes screaming by. I give Richie and anyone else (Rickdogg?) who tries this great respect, and I know there have been plenty of SR threads already, but I just wonder why no one is really interested in an SR swap for these power levels. I suppose the thought of a four banger turns people off, but an SR revving to 9K with light boost sounds like a pissed off 'Busa and makes great power. It makes more sense to me than an all NA VQ from a performance standpoint, unless drag racing is what you live for.. then you might as well build and boost our big V6.
Speedracer, the money is the thing, as people have said. NA is expensive, and swaps are discouraging. FI is easier and retains a sense of factory engineering I suppose. Food for thought.
