4 clutches? Dropping the clutch at 7000 RPM will eat any clutch as well as blow up a rotary engine eventually. Not a reliability problem, a human driver error.

Human driving error? I don't think so, bad ass, yes. If I were to buy an RX7 it means selling my 5.0 which can handle that type of fun.

If a 5.0 Tried to hit 7 Grand on the Tach it would do more than toast the clutch, and if you tried dumping the clutch at 7k you would likely break an engine or tranny mount.

Vipers...NO. 4 clutches...WHY? Some people don't know how to drive a high performance car and we all know that:)

I own a 1993 RX7 Twin Turbo. They may look like a racecar at a reasonable price at first, but if you really want to make yours fast, you have to dump some serious cash (tens of thousands of dollars).
I have put in a new engine, new turbos, a turbo timer, upgraded brakes, new tires and wheels and my car is still nearly stock. Stock RX7's are not CRAZY FAST... they run neck and neck with a stock Mustang Cobra. With a few relatively inexpensive mods you should be able to take a Camaro Z28 in a straight line and demolish any stock Mustang... but the RX7 will out handle almost anything on the road, so if you are racing turns you will come out on top every time!
The RX7 is an insanely fun sports car, but be prepared to spend some cash if you want to really get it going fast.

Yeah, RX7s are very expensive, but if you bolt on a blow off valve, your car will cut down 2 seconds on the quarter mile and add some serious horse power...

What, I have never heard of a blow off valve knocking off 2 seconds in the 1/4 mile that I think is totally incorrect.

So your telling me that a rx-7 won't be able to kill a mustang on straights with 0-60 at 5 seconds I find that hard to belive.

My friend informs me that the performance of an Acura Integra is significantly inferior to that of a Mazda RX7 Twin Turbo. That of course would be the model that was imported to the USA between 1993 and 1995.
I would be obliged if other Car Survey readers have any observations on this.

In response to what was said earlier, dumping clutches will never wear them out, there not slipping!

BOV don't add any horsepower, they vent boost in the throttle closed position to prevent turbo flutter, which is boost pushing back through the turbo.

I currently own a 93 R1, and have replaced the motor with a stage 2 street ported motor with various upgrades, such as front mounted intercooler, Greddy intake and throttle body, dual blow offs, bigger turbos, and a list of other things.
The first thing I would recommend is going non-seq on the turbos, and eliminate the secondary waste gate. This way, all the boost hits at once. Also have 3mm Apex seals installed. An Apex Power Commander and boost control also.
As for the Viper issue, well I paid 16k for the car and invested another 7k, so rough estimate... 23k, and at 480 RWHP and 2400lbs.. I can almost promise you in a straight line or road course, I'll eat your Viper. I'm on Facebook under russellisabel in Swansea, MA.
These cars are rare and specialty items, just like a Ferrari. It takes the right mechanic to tune them and dial them in, however they will slay 95% of the cars you come across, and for the $ invested with the proper tuning and upgrades, they deliver as promised a pure racer. Sure, they ride rough, sure, they have little room inside, sure, they suck gas, however isn't this what all pure track cars have in common??? It's a specialty car for a special group of enthusiasts...
Kids buy these and don't even know enough to install a turbo timer on the car. Even in stock form, this give the turbos time to cool down before shut off. This is a big reason for premature turbo and engine failure... In the right hands, this car was and still is one of Japan's deadliest sports cars. Today still Red Bull's drift car is a 93 R1. "world drift championship", look it up on YouTube! It's now 2011, almost 2012, so why is it that Red Bull has a 93 R1 championship drift car??? So that's my 2 cent's worth.
And if you have any Vipers at 55k plus without mods, send them to Swansea to meet my R1.
