Came across this while searching the local classifieds. According to the owner, an N/A '87 RX-7 is faster than a 928 S4?

All I can tell you is that the 86 RX-7 S that I owned in Germany handled like a go-kart. It had a copycat Weissach rear axle, and a light engine in the lower front, as far back as possible.

The 928 has many advantages over it (more than twice the power with less fuel consoumption), but that RX-7 was hard to bead on twisted roads. In fact, the limit was usually not the car, but the driver.

After two years, my rear tires were bald - on the outside. That's how much fun I had!

I seriously doubt a N/A RX-7 of that generation could beat an S4. A TURBO RX-7 is a different story.

The 87 Top Gear the ad refers to had a 944 Turbo NOT a 928 S4 pitted against the RX7, think it also had a Mistubishi. They were comparing the new Japanese sports cars to the "value" 944 Turbo.

As a dedicated rotorhead who also likes Porsches, I can tell you that a stock n/a Rx7 has no chance of beating an S4 in a straight line or on a high-speed track like Road Atlanta or Road America. But on the right track the Rx7 will surprise you. HOWEVER if the owner has modded that car even a little, all bets are off. A few hours with a dremel and some skill can result in 100+hp gains without a turbo. There are many 300hp+ n/a Rx7s running around that weigh a bit less than an S4 so be careful. An Rx7 with a big exhaust tip and a little smoke is likely a LOT faster than you think. I had a 1st-generation lightweight hotrod that was making about 50% more power than stock (still only 150hp or so) that would really surprise a lot of cars when it wound out to 8k rpm. Imagine another 100-150hp on top of that. I really want another Rx7 to play with, just no garage space right now.

Theres a difference in "quicker" and "Faster". It may very well be QUICKER...I doubt it faster.

I knwo for a fact that what he's saying is nothing more than hot air, still interesting to see how clueless the owner is.

If you spend enough money you can build an RX-7 that would most likely out run Mark Anderson's 928.

Sorry guys.. but I call BS on this ad.

I had one and rolled it in the twisties in college. (OK construction.. got out with a skinned knuckle) The weighting is completely off and NO WAY has the power or the balance of the 928 or a 944 for that matter. Faster my @$$.

we race against more RX7s than most any group in the country. The pro-7s show up, lots of modified RX7s but never one this modified as seen in the pics. This is a tube frame Rx7, and basically is not an rx7 anymore. (like any other tube frame racer.) the only thing "RX7" about this car is the shape. . It would be interesting to see this cars times at the track. Since it looks like a "GT3" class with Scca, even this one would be hard pressed to be as fast as anderson. in a word, NO.
rx7s are pretty quick due to their size, weight and power, but are no where near the car, on any track as an S4. Even a turbo would have NO chance against an S4. Ive seen too many of them in DEs, open tracks, and SCCA races.
one of the fastest turbo rx7s ive seen was in world challenge. 360rwhp out of a twin rotor, and he weighted close to 2400lb. He was slower than anderson but faster than me. there is a shot of it on my highlight video at the standing start.

If you spend enough money you can build just about any car that can outrun just about any other car, right.

I think stock configuration comparisons are the only meaningful ones as once the performance mods start, its just a dollars spent game.

Fun to debate and learn, but not really going to settle anything.

But those Rx's sound fun. I've never driven one, but would like to one of these days.

I wasn't talking about racers, but streetable cars that can be used for mountain drives and DEs. And no Mark, yours doesn't qualify. A non-turbo Rx7 can be easily built that will keep up with, even outrun a stock S4, without crazy racing compromises. Bridgeported 13b, uprated suspension, wheels and tires, done. Total cost will be about what a good S4 auto costs for an equally nice car.

Now the guy in the ad is really stretching the truth. His car is no way faster than a 928. It's the heavier 2nd gen, base model, totally stock. Now he doesn't say it's faster, just references a Top Gear episode which I'll bet was talking about the turbo version and some hotshoe driving it...and even that is a stretch.

I'm just saying that an n/a Rx7 faster than a stock S4 is totally within the realm of possibility without going crazy on the mods.

mark kibort

stock vs stock or even this modified GT3 Rx7, has no chance against a 928.
again, even this rx7 wouldnt be able to beat anderson and his car has a real production 928 chassis. this thing is just a mini nascar with a bigger motor than stock.

I have had 5 and two were 86-87 Turbo's. I had the 87 when i had just bought the 928, they are closer than you think. In town the '7 was nimble and quick wheras on 928 could not stretch its long legs and never got a chance to get wound up. On the highway anything past 70 the 928 was faster.

mark kibort

In street stock form you are probably right. but equal mods, the 928 will have the edge. Those new body style versions with the turbo were very fast and much lighter than the 928. specs would probably stack up pretty even, and in stock form favor the Rx7 in a track use comparison
