the car is an 87 t2 on stock turbo with some basic mods, boost 11 psi. I have tried every thing i know but the car still floods all the time! the only thing I know thats wrong with it is a small exaust leak that makes it spool late, around 3500 rpms. any ideas? other than this car runs great.

 

Here is an idea.. What does a turbo timer have to do with flooding?

You either have:

1. A malfunctioning sensor, check your codes
2. A leaky injector, clean your injector
3. A bad motor, fix your motor.

 

turbo timer doesn't do squat for your stock turbo...

 

i was just gonna say that.............hey I have my oven set to 450* but the wart on my pinky won't go away.

 

Do your fuel bill a favour and don't bother with the turbo timer. Water-cooled turbos don't need them and they sure as hell do nothing for flodding problems. What made you think it would? The exhaust leak will have nothing to do with this either.

The two most likely causes of flooding are low compression and/or leaky injectors. Get a compression test done to see if it's rebuild time, and remove the injectors and have them professionally cleaned. Even if they don't turn out to be the cause, clean injectors are always a good thing.

 

to avoid flooding....while the car is turned on......and on neutral....rev it to 3000......hold it for 10 sec......then at the same time turn off the car.....and let go of the gas........this if on your rx-7 owners manual.......and yeah maybe your injectors are leaking....or maybe its rebuild time.....you are boosting your turbo to much....for stock that is

 

lol, all these tricks. Particularily this one, I just cannot see how it will work. If anything, the higher RPM with no spark is just going to create more vacuum for your leaky injector to inject fuel into!
The one way that does work is a fuel cut off switch, you starve injectors of fuel and they cannot leak. The below approach does not do that.

 

Mine flooded pretty consistently, so I sent the injectors to RC Engineering to have them cleaned and balanced. One was leaky and a couple were not flowing very well (I was very satisfied with the service BTW). All said and done, I got them back like new, popped them in, and the flooding problem is no more...just like that. I can't tell you the smile it brings to my face to be able to start up like a normal car, without kill switchs, flooring the gas pedal on start up, etc.

 

black plauge.....i see what you mean.....but this is actually on your owners manual......and it actually works...unless you have leaky injectors or bad compression......but personally i dont do no tricks.......i just leave my car on for like 1 minute then i turn it off...thats it...if you dont have time to wait go buy your self an automatic cool down.......

 

Yes what werwuryoantenaz is very true I have been doing the 3000 rev for a while now and it never fails me I just rev to 3000 and turn it off I don't hold for 10sec but you can, if I don't do this it pretty much always floods then I got to push start it

 

Guess im wrong, I had no idea it was in the owners manual. Honestly though if you think about what I said, it does make sense, obviously though, thats not what happens.

Thank you for the correction, I apologize.

 

only human....its cool....im glad i can help.....that is how WE learn about cars......10% reading......and 90% WORD OF MOUTH......

 

well I bought the car from a club member, when I told him about the flooding he said use the turbo timer I dident think it had any thing to do with that. I guess he was wrong and thanks for the help. Have to say it sucks when you trust what one person says then ten people call you a dumbass for it! oh well thanks for the advice. maybe I hope I know my t2 better soon.

 

You sure like to put words in my mouth dont you.
I told you that if your running your car for just one minute and shutting it off before it reaches running temp then you may be flooding it. Then I told you you if you do that use the turbo timer to let it run for atleast three minutes after it is started.

If you dont trust what I say then stop asking me for my advice.

Ill find the exact PM if you want me to that hs this converssion on it.

 

I Got A 87' Tii With 136000 Miles On The Engine And I Just Pop The Hood And Take Out The Injector Fuse Every Time And Never Have A Problem With It

 

yup....pull the 30A EGI fuse....crank for 5-10 seconds....re-insert and you'll be ok.

 

umm ok

 

ya i had a fuel cut off switch on my TII i would just turn it off before I tried to crank it and then turn it on after a few a second or so of it trying to pick up gas.

 

Best thing to do, is fix the actual problem. I had the fuel cut off switch too, it just sucks having to do all of that, and wondering if it will work next time. Like I said, one of my fuel injectors was leaking, and fixing that solved the problem. Don't settle for band-aid solutions.

 

well found the problem, bad compression and now blown apex seal. oh well time to rebuild.

 

I didnt mean to sound like an ***, this is just the second time Ive seen you type ignorant **** about me for no reason.

Also, who told you that car has bad compression?
Have you loss any power? If not then there wrong also that engine has only 40,000 miles on it.

If it does have a bad seal then lool through that paper work I gave you. Mazda might honor the egine warranty.

 

well I will start buy saying " I got the car from a club member" I did not say tom my goal here is not to make you look like an ***, it is to fix my car. well the goal was to fix my car, and yes the motor is blown. I hope mazda will honor there warranty I have all the paper work you gave me hopefully that will be sufficient proof that was was infact a mazda reman. I still cant believe a motor with 45,000 miles blew an apex seal especially the way I drove it never did shift past 6k. and I also pamperd the hell out of it. The day the motor went, I was on my way to get a new fuel filter, but i guess I was allitle late, buy the way did you happen to change that ever when you had the car?

 

From reading your other post I guess I was right-the apex is fine if it has good compression.

I remember you raced the car several times after you bought it. Were you putting in premium fuel when you were racing it?

Also that car boosts past stock because of the exhaust. I remeber telling you not to boost that high on a daily basis.

Did you check the turbo? Its a rebuild engine, but the original turbo so that wont last for ever.

Oh, and the previous owner told me that he put a new fuel pump about a week before he sold it to me. So that means it probably has less than 20,000 mls. on that particular one.

Ofcourse I dont mind questions from you, just dont assume everything wrong that goes on with this car is because of neglet or stupidity on my part like you implied on this thread and on your T2 mechanical fan thread. ITS A TURBO RX7 your gonna have more to **** with than your n/a.

Also Im a little confused because in one thread your sayin the car runs perfect and another you saying that your having problems????

 

running higher then stock boost, on stock engine with no fuel mods,leaning out 1 ping= broken apex seal....

 

well the motor is not blown i had mazda dheck comp behind me to make shure it was ok and it was it is just a problem with the turbo not that big of a deal.
