I already know what you mean pal. The pulsating you feel when you are cruising is very annoying although it does not effect performance but here's your answer.
Timing and Ignition!!! If you are using low octane such as 89 or even 91, you have to tune your car to run that otherwise you run lean and while you are driving, your car tends to "dehydrate "LOLOL because it's wondering where fuel is.
Also there is a stupid carburetor like function on your intake called "Cold Start Screw" It's ta very tiny screw located on the upper intake between the Idle screw and TPS screw. I back it all the way off because it is a useless piece. The computer makes the engine run at a higher rpm when it's cold and then it goes to operateing temp mode.
Here's a shorter answer for your pumping issue...
Use The octane suggested - 93 octane
Change your Plugs and wires
BIGGEST THING TO CHECK - POSITIVE BATTERY CABLE AND GROUND CABLE: WHEN THE BATTERY CABLE CRAPS OUT, IT TENDS TO GIVE YOU LOW VOLTAGE THUS YOUR SPARK IS NOT HOT ENOUGH AND SO FORTH. WHEN GROUND WIRE CRAPS, YOU SHOULD KNOW WHAT STARTS THEN...
If you choose to use cheap gas, Tune your car to do so and do not believe everyone about using a laptop, they are retards. You tune the car like you would a Carb'd mustang or even a 5.0... Timing light! and you have a distributor but it's actually called a crank sensor.
only with alot of money for mounts and you also have to cut the frame and all that crap in otherwords no it wont if you want a 79 motor you might as well just get a 79 rx7 its well worth it to do that anyways its lighter
mazda doesnt rx7 anymore :(

fuel pump relay under dash checked the fuel pump relay under dash, it's good.... has to be another problem.
In stock form, the turbo supra was faster than the fd rx7. The 93-95 rx7 are quicker in the quarter mile. My 1994 rx7 is highly modified and runs 10 second quarter mile times- quicker than any ferarri or lambo/ porsche.
The Mazda cx7 is not as good as the Rx7. The Rx7 has more power, better fuel efficiency and a sleeker appearance. The Cx7 is actually not as good as a Honda CR-7.
An odd stud pattern on the s3 1984 rx7 . It's 114.3x4...

A second gen Rx7 would be much faster.

the surge the engine does when you first start it up is normal, the engine is built to do that to assist with warming up the system it should lower after 30secs or so.
