what are you smokin?

the switch to a V-8 powerplant has an effect on performance too. The additional low-end torque makes the RX-7 very easy to drive, and is available throughout the RPM range. No longer will you have to excessively slip the clutch at a stop light to keep from killing the engine. No longer do you have to downshift, wait for your RPMs to come up (or boost to build) to pass a car. No longer will you live in constant fear of the dreaded carbon lock. With the V-8, your power is always available. If and when it comes time for an upgrade, things can really get interesting. Simple $100. modifications can result in 15-20hp increases, while spending a mere $4-5000. can get you up to around 500hp level. We are seeing low to mid 13 second 1/4mi times from mild smog legal engines with around 300-325hp, which is better than the high 13 second times that were possible with the 3rd gen RX-7’s stock twin turbo rotary engine.

If I had to choose between 2 gas guzzling engines I'd go with the one that sounds good, makes usable power and is reliable.

the reason your car is slow is because it is slow, not because of the engin e but becasue of the stock 350 tranny. you need a turbo350 then your trann y wont slip anymore. and your car will be OUT

You should have kept the 13B. Reactive racing RX7 Stock engine=7.6

doent look slow to me...

Looks slow? It is slow, you moron!
