hi everyone, I'm not going to start that "hi everyone new to forum blah blah", i just recently bought my 1995 silver rx-7 3 weeks ago(bone stock with 87k miles on it =/)recently had a 2001 celica gt-s. Drove it for 3 days and my powersteering belt snapped, replaced it. drove it for another 7 days and my batery went out, replaced it. Now for some reason after i chagned my batery it reseted everything, and my turbos are not spooling as it did before my batery went out?it's only been a day after i changed the batery. can anyone plz help me and tell me whats going on? is it just relearning the fuel maps and everything or do i have to spend more money on this car? First when i bougth it the fun of driving it outweights the maintnance, now those numbers are starting to look even. Thank you.

 

Hmm. Sounds very strange. First thing to check is that you have grounded the battery well. Hopefully poor grounding is the culprit.

 

welcome to the world of rotary's, check your vacuum lines and your couplers from the crossover pipe to the intercooler and to the throtle body..,

Have you also tried using the search feature there are a couple of threads that may have the answer you are looking for..

Goodluck

 

thank you guys for your nice replies, i see some of the other ones man they are brutal *shrugz*. Yeah one thing i forgot to mention this is my first turbo car, i dont know much about turbos and also this car is a rotary engine also something i dont know, i bought it cause i wanted to get chicks. i guess id idnt know what i was gettin myself into

 

Do not get the wrong impression about this car. These cars need care and maintainence, just like any other high performance car. Take care of the car, and you will fall in love with it. Like I said before the first time to check is that the battery ground is clean. changing out a battery should not affect the boost in any way, other than a poorly grounded ecu.

 

ok so your telling me to take out the batery again, and clean the ground of which i place the batery on? Thats what you think it is? thanks for your reply

 

You might have shorted the flux capacitor when you hooked up the new battery. You can find it on the passenger side. You can check it with a tester.

 

hmm damn man i think i should just take it a merchanic i not good with these things, but also, you think 87k milage you think i should get a new engine or an overhaul or something?i think it had an engine change at 36k, but still it's still alot of milage what you guys think? this thing is starting to make my wallet to skinny =/

 

Well I would rebiult it while the motor is good (no blown apex seal or water gasket). If You do it yourself it would be cheaper than getting a reman. Is not hard to rebuild it if you feel confy doing some wrenching.

 

I have 124k on mine now. There's a good chance that your engine is fine. Try disconnecting the ground on the battery and use a terminal cleaner to scrub off any corrosion, exposing fresh lead. Sandpaper works in a pinch if you don't have a terminal cheaner. Try that and see what happens. Does your car happen to have a boost gauge? If so, drive to 3rd gear. In 3rd gear at around 40mph, floor the car. your boost should jump to 10 psi. when the secondary turbos come on line, you will see a drop in psi to 8, then it should rebound to 10 all the way to redline. So, essentially you should see a 10-8-10 boost pattern. If you do not, then somewhere along the way you are having a boost problem. When you say that your turbos are not boosting as before, are you just judging this by feel? Perhaps you are only perceiving poor boost or is it quite obvious. A lot of times when sitting in traffic, your i.c. develops heatsoak (especially the stock i.c.)and when you try and go fast, your car will seem sluggish until your ic is able to drop the air temps back down. Hot air = less dense air= less oxygen going itno your engine= less HP. If you have good grounds, and still have an obvious power loss, then I would venture to say that your boost issues and the new battery are in fact not connected. Good luck.

 

thx a lot overkill thats a great help but like i said before i not really good with these things but i will try waht you said, but i think a thorough diagnostic would help a lot too i know a friend that can hook it up for 50 bucks, thx agin overkill
