hmm, yes. I had 175k miles on mines. I think the misconception(?) that rotaries dont last, specially the 3rd gens, is that people used to increase boost without the remainder of the necessary modifications.

 

197,300. Lost a lot of power though. I put on a Mikuni sidedraft at around 195,000 and didn't gain any horsepower. I put on RB headers at I think 185,000 and there was a noticeable gain until I overrevved to about 83-8500 and destroyed the stock Nikki. I think now that I have a car to "get around" , I'm going to completely tear apart my 1st Gen and build it like no other. I'm gonna stay 12a though. Hmm.... are 12's possible with a 12a?

 

Not unless you've got boost, lol. I don't even think a fully built 12A w/ a PP port would run 12s...maybe. You'd have to have it gutted and only weigh like 1600lbs w/ over 300HP all motor...but it won't come cheap or easy...

 

What the?! You're a psychic. Exactly the same weight I was shooting at and about hte same HP too Maybe I'll go 12a turbo...

 

dont need to go turbo for 12's in a 12a i've seen cars set up right run in the 11"s with a pp 12a , but they weigh about 1800 lbs and run slicks you can also run 12's with a 12a bp and nitrous with about a 75 shot

 

I believe you can run in the 13's with just a header, paul yaw carb, and some ignition work.



Another thing I wanted to mention; are you sure its a carb problem? I don't know what else it could be, but when the car isn't running like you want it to, often the first thing people blame is the carb. Have you done the usual tuneup? plugs, rotor and button, wires, filters, fluid change? I don't know if you mentioned doing the ATF trick before or not, but I would definately recommend doing it.



About the ECU, I've been told that the carburated '7s do have an ECU. Thats what all the vacuum solenoids are connected to. If its not right, youll run rich/lean, and it also comes into place with your igntion timing via the advance pots.

 

When I first got the car about a month ago I did a basic tune up. Plugs, fuel filter, oil filter, and oil change. I haven't done the rotor, distributor cap or the spark plug cables. I plan on doing the atf treatment after I rebuild the carb.



The carb looks like a flying soccer in it's self but I'm pretty confident I can handle it. I've rebuilt a few carbs on trucks but nothing as advanced as the 7's.

 

I don't know if this is important or not but after I accelerate as the rpms come down the exhaust pops and sputters. I was told that it had to do with the timing.

any ideas of how I can fix that?

 

that is probably your exhaust leak. or it could be a bad shutter valve in the intake manifold (just plug or remove it).

 

reliability in an rx huh! I don't know much about that I mean my 86 n/a only has 198,000 miles on it and my dad's 79 only has 320,000+ on his but as for reliability I don't know.
