There are some good comparison comments about the 993 in the FAQ
here.
As for the 328, that's a
much older model than the NSX. The NSX can walk all over it in every way.
I've driven a 993. Here are the comments I wrote down at the time:
Well, today, for the first time in my life, I drove a late-model (but not 996 and not turbo) Porsche 911. I had lunch with a friend, and we switched cars for the drive from the office to lunch. In the past, I had ridden in Porsches numerous times on the track, but always as a passenger.
What a HUGE difference in driving feel! It just felt so very different. I had figured that the driving experience wouldn't be all that different from one high-performance car to another, but I was mistaken.
Impressions:
Who the heck designed these pedals? Were they nuts? Yes, I had heard about the hinges on the bottom of the P-car pedals, but that's not what was so weird. First of all, the amount of travel of the clutch pedal from the bottom to the top was enormous, even though the effective range was just as narrow as the NSX. Who needs all that pedal travel? It just makes it difficult to find the effective range, that's all. Secondly, the gas pedal seems like it's about 20 inches further away from you than the clutch and brake pedals. But then that clutch pedal has so much travel, it seems as though it travels that same 20 inches. Totally incomprehensible.
The dash. Not bad. The NSX dash has a depth of maybe 8-9 inches from the steering wheel to the gauges. In the 911, they're almost in the same plane. It was actually rather appealing that way, because your eyes don't have to find the right focal length from the wheel. Nice.
The gearshift. Also pretty good. The throws are somewhat longer than the NSX (bad) but worked very smoothly (good) and was actually easier than the NSX to put into the proper gear. What I mean is that, there are times in the NSX when I'm not paying attention and sometimes try to go to third and instead go to fifth or vice versa. That would be more difficult with the 911 because there's a much more positive feel in the left-to-right positioning of the shift lever. I might have given Porsche the advantage in this area, but they lost it when they designed reverse gear. Having reverse in the upper left position was strange to begin with, and it was extremely difficult to engage reverse, requiring a lot of pressure and was quite notchy.
The HVAC controls. Ancient hieroglyphics. They must have hired Mel Brooks playing the 2000 year old man to tell them how to label them with those cave man markings. Let's see, there's a big snowflake, that must be the A/C. But why are there TWO different buttons with snowflakes? Why two slider controls? And this knob must be the fan, but when I turn it, nothing happens. (I found out later that there's a brief time lag before adjusting it has any effect.) It seems to me that HVAC controls should be very, very simple. There really are only a few things you can adjust - temperature, where the air comes from, where the air goes to, whether it's chilled, and how fast the fan blows. Not rocket science. ANY car today ought to have simple, easy-to-understand HVAC controls - and most of them do, even your everyday family sedan. But not the 911.
The stereo is an Alpine. I don't know if it came with the car or was aftermarket, but one look at the tiny size of the buttons convinced me not to even try.
Glove box - small but worked okay. The arm rest in the door flipped up (I forget why) and just struck me as junky.
Okay, okay - we get cars like this to DRIVE. So how was driving it? Unfortunately, the route we took had almost no turns, so I can't comment on sheer cornering ability. But the steering is nowhere near as responsive as on the NSX. Like the A/C, there seemed to be a lag. Turn the wheel, wait a half second, and yes, then the car turns nicely. Whereas the NSX seems to turn like magic, as soon as the thought crosses your mind, before you even turn the wheel.
The brakes were very nice - not the killer brakes I had heard about, but smooth and effective. Although lately my NSX brakes have also felt quite good, and don't seem to me to be the weak point some other folks feel they are. But that could be because I've been using aftermarket pads, rotors, and fluid on my NSX. So that may be an unfair comparison.
The power just didn't overwhelm me, but the horsepower curve seemed much flatter than in the NSX. With the NSX, if you keep the revs in the 2000-3000 range around town, there seems to be very little power. But (as we all know) get the revs up over 5000, and it turns into a screamer. Whereas the 911 seemed to have more power than the NSX at the pussycat end of the rev band, but I never really felt it take off the way the NSX does, even when I had it floored at different points in the rev band.
So those are my impressions. To sum up - the 911 is supposed to be a car that competes with the NSX. Before I drove one, my assumption had been that overall I would find it to be an equivalent vehicle - better in some areas, worse in others. But as it turns out, I was quite disappointed. In my personal opinion, I felt that it was just not a very impressive car, with capabilities that don't even come close to the NSX, and features that are are not only user-UNfriendly, but bizarre and senseless.
