If it says Catback, its obviously not a turbo back

anjoO, please excuse those youngsters on here with a short fuse

you did explain that you didn't know much.. remember we all start here nowing nothing, but hanging around and reading/posting is what makes you learn. please don't take any posts to heart newbie

i'll try to explain it easily for you:

combustion happens in the cylinders - a chemical reaction occurs between the air and fuel and this creates exhaust gas.

where does this exhaust gas go? well it has to get out of the cylinders so that more air and fuel can get in. there are valves at the top of cylinders that open up and the exhaust gas leaves. it flows through an exhaust manifold, and over the exhaust wheel of the turbo

(the turbo is basically a long pole with a wheel at each end - one end sticks into the exhaust gas and one end sticks into the intake air)

so gas flows over the exhaust wheel and is now into what most would call the exhaust. so you've passed the turbo now, everything from here is "turbo-back"

gas is still up at the engine, just having passed over hte exhaust wheel of the turbo, and it is into the next pipe which is the dump pipe. this is a short piece of pipe that connects to the front pipe

the front pipe runs down under the car and bolts onto a catalytic converter. now i know you've heard of this device.. if not, its a container filled with chemicals that lets exhaust gas through it and reacts with the gas to remove any nasties

after flowing through the cat you are now in what is termed "cat-back" which is simply a pipe that goes to the back of the car. you might find a resonator or somewhere here to make the car less droney, but you will definately find a muffler at the end to damp down the sound

so, to summarise: (this shows the names of the pipes that the exhaust gas flows through to get out)

cylinder --> exhaust manifold --> turbo --> dump pipe --> front pipe --> cat --> cat-back

hope that helps :laugh:

well described waz, but i think that it would be a good suggestion that anjoO learn to search the forums in more detail rather than posting 5 new threads a day that there is plenty of information on.

Just suggesting nicely...

If it says Catback, its obviously not a turbo back

the quesiton was what makes up a turbo back no shit a cat back isnt a turbo back

anjoO, please excuse those youngsters on here with a short fuse

no worries man, i hate to admit it but i guess i am a newbie wen it comes to this stuff....and it shits me wen i ask something only to be flamed at because i no little to nothing.

damnet im gonna go on whirlpool forums and flame some newbies about computers to feel better hahaha

Maybe he should have asked the question in this thread "Exactly What Makes Up A Turbo Back" in his other 4 he made about exhausts...

I know you only learn by asking/reading, but maybe try and merge some questions into the one thread rather than starting a new thread each time.

Cheers.

hey dude.

i dont think you deserve a flaming HOWEVER! i suggest otherways of learing stuff about cars ie:

a: use the search button. (but i struggle with that too)

b: car mags, theyre fantastic they have all a man could need (cars, ladies etc)

c: www.howstuffworks.com has many useful articles on cars. look into it.

d: browsing the forum is good to pick up on things too.

cheers :D . james.

Great explanation Waz

Nah man no need to keep it to a minimum..

Before Posting these questions, just search.. Just type in random stuff related to exhausts. Then go thru each link that popped up. Read thru it. learn from it.

Then if you are still stuck then post.

So best to search for threads before posting.

We all started from nothing, but best to learn from asking also your friends also, or read some threads related to it, or car mags etc etc.

Then if you are still stuck ask away...

Wel all dont know everything, except for Sk.. but hes different. hahaha..

But all the best..

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
