Turbo problems?

[suprra_girl]

turbo's + backpressure don't require each other

more than likely you may have a small boost leak
check all your clamps & intercooler pipes for splits/holes/cracks
when on hard throttle do you hear air rushing from the engine bay?

[TxSpeedBoy]

Yes I do hear rushing, like that's all I can hear. What does that mean?

[suprra_girl]

make sure ALL of your intercooler pipes are connected well and dont have holes in them

check the pipe coming off the turbo.. that's a common culprit and check the one between the throttlebody and manifold as they commonly split

i would say it's only a small leak as she is idling ok isn't she?

[TxSpeedBoy]

She is idleing ok, but until I put it in drive it idles about 1100-1200 rpms. When in drive she idles 800-900 rmps. She also doesn't start the first time after she's been off for a while. Sometimes it takes as much as 4 attempts. What's the deal with this? I'll check the piping too. I took it to Toyota today and they did a free visual inspection. Everything for the most part is ok, but I need new pads for sure all the way around, and most likely rotors too. Any idea of where the best deal for these are. They wanna charge $151.00 for the front and the same for the back totaling around $300.00 for just the pads...I think. I would like to do them myself, but don't know if I have the know how or the facilities to do so. I checked the oil cam for the chocolate milkshake stuff and none was around the immediate opening, but down in there just looks like oil. I couldn't find the bolts though. Know of any sites that have diagrams? What do I have to take off to get to the bolts? I think it is in the cylinders too on account that I have no cd player so there is a hole there and when I get on it, I can see burnt oil coming out. I am thinking it needs new gaskets and seals. Any advise? Cost predictions?

i though the boost was suposte to stay a negitev at idal

or is it suposte to stay at 0psi at idal

[TxSpeedBoy]

I went to look at a SRT4 a little bit back before I got my Supra and the guage in it stayed at 0 psi and when I hit the throttle in neutral it went up. On mine, it doesn't move no matter how hard or long you hit the gas.

[suprra_girl]

it is very rare for the 7mgte to boost in neutral... don't worry about it
