1JZ Sounding like bubbles NOW THE FARKIN TURBO IS GONE

Hey guys, when I first got my car back, the engine ran very smooth, even though, it has not been tuned yet, idles nice and all. Now and then though, (Its actually almost always now) it sounds like there is air bubbles or something in the exhaust. You know that sound, where you have hi pressure hosed the engine bay, and water has gone inside the spark leads? Exact same sound, but I have never used water in the engine bay. What could it be?? I seem to have loss consider amount of power because of this also.

head gasket --- is the sound exactly like the wrx with modified exhaust then most likely thats what it is dont quote me on it though
check for oil and water mixing in the radiator/coolant reservouir if its been happenin for some time there will be rust brown water in the radiator/reservouir due to the head being corroded hope thats not the case chek it out asap
it could also be a stuffed up injector / injector connector

Perhaps someone put bubble bath in your sump instead of oil?
But seriously I have nothing useful to offer

do you mean little popping noises every so often from the exhaust?
if so, that is what my old 1g used to do. Unfortunately, I never found out why, but it didn't seem to lose any power so...?

HEADGASKET??? Dont say that!! Please! Thats a big job right? But thing is, sometimes, it works perfectly! Yep, sounds like a WRX when you accelerate, but goes like a Lada. Hop it is the injector problem!

could be a bad lead too, check your sparkplug leads, best way to do it is look in the engine bay while the car is running and it is dark, like night time  , if u see sparks then that is why, this is what it sounds like to me, as u said, sometimes it runs fine. Also u can check them for cracks etc.

yeah if the plugs are fcuked they will do the same thing take them out and clean them with kerosene nicely put them back and if no difference then chek the oil as i said before if its milky colour / als chek colan for same milky residue on the reservouir cover /bottle if theres any take it to the mechanic straight away
is the car running rich as well can be a temp sensor fcuk up but i doubt it that wouldn make the car sound like the wrx
can be clogged injectors as well
do not drive the carin this state as it can do more damage
hope its ur injector or eveb better fouled spark plugs
BTW DID U RECENTLY CHANGE ENGINE OIL FOR THE CAR
if u put in too much of oil it will foul the spark plugs causing the car to sound exactly how u described it so chek the spark plugs first

I had the identical thing happen to me in my 1jz with Haltech! The cause is the tuning being to rich and then fouling plugs and they appear to be very sensitive to temperature. For example, my car was tuned by Matthew Spry formerly of Chiptorque, in summer in Qld bring it to Tas. and car "blows bubbles" in winter when it is cold-cause is too rich!!!! Don't ask me how their can be that much difference between summer and winter and Qld and Tas. because I don;t know. All I know is that it was a waste of money getting a tune that I can only use three months of the year in this climate. Hope this helps.

ooo, Thats a good point, as Im running E6X, and JEM have not tuned the car yet, just adjusted the idle, and set the rev limit to 5k, so I can use up my old fuel.

what do you mean you don't have the tools?  Just buy one of those $15 sets from super cheap. It is nothing special just a 16mm (i think) long socket.
also, my earlier comment probably won't be right as I thought you were talking about a different noise.
Does it sound like that idling as well? if so, you can just pull the plugs off the coil packs until the noise doesn't change. Then you have worked out that it is that cylinder. Then you can check the plugs, coil packs for any weird looking shit like cracks etc. Then try removing the plug from coil pack and cranking the car over. Then pull the spark plug out and see if there is fuel all over it. If there is, then the injector should be fine. If there isn't then start looking at injectors.
Just think of it that to combust, it need fuel, spark and air. Has to be one of those things so it is a process to work it out which one.
good luck!

Was what you were hearing mainly when you backed off, especially from higher revs, or using gears to hold you on a hill?
If it was, that was teh exhaust cackling...
It is cause by the exhaust scavenging out half burned mixtures... It happens in every single car, just some you can notice it in, others you can not...
My ute does it ocasionaly, our old chev does it on hills, and our Camaro just rumbles and cackles when backed off on hills...

Jag, I did not do the conversion, I do IT, thats it hahah.
WELL! I fixed the problem, its one of the coils, when unplugging it, the engine note was the same, plugging it in and out a few times, brught it back to life! BUT (Always a fucking but) This morning, I started her up, 50 m down the street, I hear a jingling type noise, like a rattle, I though ohh no, then the car stalled, I think one of the turbines went through the exhaust! Unbelivable, Had the car for a wekk, never got to give it any hits whatsover, and now this happens! There is no boost now, whatsover! Fucking pissed man!

bloody hell man you have the same bad luck as me!
Personally, as the piping and everything is all done, I would go steel wheel turbos and while you are at it, some twin dumps if you don't have any.
Probably easier in your car than mine, but going single is going to be harder than just fitting steel wheels into stock turbos.

I think im just going to buy a set of steel wheels, got one lined up already. What are the benefits? Run more/safer boost?

yep, more boost safer. You can get them hiflowed as well if you wanted. There is a tiny bit more lag but it is shit all I reckon. My mates jzz30 hits boost around 2600rpm with steel wheel turbos.

Just check your cat converter first as thought I had the same problem. My exhaust rattled and couldn't make more than 5 psi boost because the innards of the converter collapsed and was choking the engine so it couldn't make anymore boost. Everyone told me it was the turbos as well bbut when I pulled it all apart they were fine! Yours probably are gone but it would pay to check the cat anyway......might save you a lot of hassle. My cat was only a year old too!!!!

And you'll probably find your old turbine wheel in the cat too

a friends vr4 had the same problem
he tuned it with haltech, the next day he replaced the spark plugs with another brand and the car sounded like a ej20.
If its not that check the exhaust sensor

Had exactly the same prob with my R32 - no boost, pulled the cat out and it had collapsed inside. I'm guessing you would have all new exhaust bits though?
And Shane if you're changing the turbine wheels, you'd be silly not to high-flow at the same time IMO.
