I know at first when I got my auto I was happy with it. I did all the useuall upgrades to it such as DP, CB, intake, pulley and I was pretty happy with it. I also went through the hell of upgrading all my vaccum lines and replacing all the coolant lines just to be safe. That is until I got it dynoed 2 days ago and I found out because it is auto it is only making 230 whp. If it were manual ied be making 290-300 whp but being the dumbass I was when I bought the car I thought that Auto wouldnt be that much different (power wise) and oh boy was I wrong. So my advice to you is dont expect to make big numbers easy out of the auto. If you want big power convert it to manual ASAP.

 

Trade it in for a 240SX or whatever.
It sounds like you don't have the skill, patients, or love for these to deserve to own one. You're just going to end up breaking the car or killing yourself.

 

I beg to differ. I have full exhaust, intake, FMIC, etc. I have no boost spike or any problems with leaning out etc. My motor runs fine. Some of that stuff is a myth. Although i have heard oif it happening, so i wont dismiss it. I also live at high altitude, which saves me from boost spikes.

 

ya, that was a little mean. Dont forget, a built auto will rape a manual. Not bleeding boost whil shifting is a wonderful thing.

 

Ignore these guys telling you to sell the car blah blah blah. They are just overly **** about seeing an FD in a young guy's hands. I understand completely how yu want to burn out and all. But understand that it can't be done in the automatic FD. Also understand that according to some of these guy's doing Jonski's launch hurts the tranny. I've been doing it for a long time and my tranny is fine. I'm also sure Jonski has been doing it longer and his is still kicking some ***. Oh and another thing, 2nd or the S position with the hold button is the sweet gear. Thats where most of the power is from what I can tell. So you should definetely follow their advice. I would suggest not going to Mazda for them to check it out. When it comes to turbocharged rotaries they have no clue. Find a rotary specialist, there should be one near you that can check everything for you. In fact you should ask him to go over the car with a fine tooth comb for other problems.

Yes, the FD auto is a sponge! Man I can't wait to get rid of it and get a 4.3 rear.

 

Ahmen brother.....


Dont fall into the, but "I" can fix this car...I'll build in better, stronger, faster (theme to bionic man in background)

So many Auto owners have tried, and failed. They pour countless hours and $$$ into upgrading an Auto with bolt ons and tranny upgrades only to barely even match a stock 5spd performance and hp.

Do you even now that the Auto tranny thats in your 7 is the same tranny that's used in the Mazda MPV mini-van and 929?? You've got a ****** mini-van tranny in your 7.

Try sleeping with that at night!

 

look the fact is yes you can stay with the auto and have fun but if you want to do burnouts and kick some *** at the races then convert it to manual. with the auto you lose 60-70 horsepower in comparison to the manual due to drivetrain loss and no matter what you do that power loss will always be there.

 

OK so you guys dont think im patient but your wrong. Im just tired of my car being out preformed by so many. A 1992 Oldsmoblie did a better burnout than my car and that is just a disgrace to the rotary. So I went out in search of answers and no matter where i took it no one could tell me. Im not impatient I just dont know what the problem is and I would like to find out.

So heres whats on my checklist so far.
ECU
Boost Controller
Boost Gauge
FMIC
Manual Tranny Conversion
Vaccume Lines (somthing like that)

Probably about 8k

or sell it and
Buy a Supra TT 6 speed

 

This has nothing to do with your patience, it has to do with modifying your car without realizing the conesquences. The statements you made in your first post make you look somewhat childish, whining about how your car is slow and can't do a burnout, which is why a lot of people made the statements they did. If you haven't worked on a turbo car before you have a lot to learn. Just buying a car because you thought it was fast, probably isn't the best buying decision. Automatic RX-7's are decently fast still, and they make good candidates for a 3 Rotor, however the transmission has issues in handling much power, and I believe the ECU is a bit different as well. Unlike on a Supra, where I would buy one with an automatic transmission because there is aftermarket support, and the automatic transmission is the way to go for fast, reproducible track times without major expenses. However on an RX-7 going with a better automatic transmission is a major task, and expensive, only reserved for very high end drag racers. First of all, if your car is not running way to rich, backfiring a lot, and driving like crap then you probably have a turbo problem. With all the mods you listed the ECU is going to run way too rich, but when you step on the gas, you can run lean and there goes your motor. Or your motor could already be toasted. First of all, you can't just open up all the exhaust etc. on an RX-7 because the stock ECU will not compensate correctly. Intake, Downpipe, and Catback is about the limit you can do with the stock ECU and even then the car has a tendency to run rich and back fire a lot. When I bought my car it had a Power FC ECU, downpipe, and catback, when I installed injectors, midpipe, and front mount, I was pretty worried about even driving the car quick until I got it dyno tuned even, so just getting an ECU is and boost gauge won't solve that problem. Which brings me back to your problem, without having a boost gauge you have no idea if the turbos are spooling up or what, unless you have the BOV vented, but even then I drove an RX-7 that our dealership took in on trade and it was seriously lacking power, no one else that drove it noticed anything was wrong and just thoughts RX-7's were slow, but I knew better and the turbos weren't spooling, so I didn't buy it. There are a lot of problems that can happen with the turbos on these cars and you might not even know about it. You need to get a boost gauge, and have a Rotary expert, or Rotary shop check the car out for you. Even with the automatic, your car should be pretty quick. I wouldn't recommend a manual transmission conversion, as it would be very expensive unless you are highly mechanically inclined and can do it all yourself, even then it will still be expensive. Spend some time searching these forums and learning about these cars, and I would recommend getting your car checked out, and the problem fixed, and make sure your all safe in the ECU, fuel department. If you still think its slow, then sell it.

 

look the fact is yes you can stay with the auto and have fun but if you want to do burnouts and kick some *** at the races then convert it to manual. with the auto you lose 60-70 horsepower in comparison to the manual due to drivetrain loss and no matter what you do that power loss will always be there.

 

And if you have the cash and want a quick fix.... Its about a 4 hour drive for your down to Pettit Racing (www.pettitracing.com).

Cameron has so much experience with the FD's its like he has ESP.

He will find/identify correctly everything that is wrong with your car, in a about 15 minutes.

When I bought my car I bought my car that was the first thing I did.

Cost me about 1k for a Vacuum hose job, complete tune-up, complete fliud change (Evans coolant, Redline MTL, etc), a boost gauge, Alum. AST, Power pulley and belts.

Plus he fixed/found about 10 minor problems I didnt even know about.

Best money I ever spent on the car, by far......

 

Good grief sorry for the poor grammer in the above post...I was typing while on the phone.....

 

Perfectly said....I'm not Cam but I'm pretty confident I could get it running real smooth if he brought it by here....hey I offered. Don't bring down the fds name by losing to hondas please. Just park the car and sell it if you don't know what you're doing. And btw pettit is A LOT farther than 4 hours from jacksonville.

 

HAHAHAHAH!!! *OUCH*!

 

^

Werd.

The car is no way compareable to civics, blah blah blah. This car is one of the best handling, powerful, sports cars around.

If you honestly don't like working on cars, just sell it to someone who does.

 

dealer is evil ....

 

Ya I know, and that was selfless act of a true FD owner/lover.

And I dont think this guy falls into the same category.

He's seems like more of the TF&F wanna-be type, as its pretty obvious he didn't do ANY research
prior to purchasing his FD.

Hope the guy takes you up on it and it all turns out well for him.......

btw jacksonville to Pettit in 4 hours is par for a properly running 5spd FD
