Tryin a ting wit the BJ - Exhaust Done

Strugglerzinc

Having a BJ for bout 3 months ah decide to try the free/cheap stuff first and move from there.

Step 1 Remove cats

FSM say it suppose to have 2 but i only find 1, a silvery color one lower down the pipe that will get cut out very soon. There was none just after the manifold.

Is this manifold the normal one on the ZM engine?

may not be obvious from the pic but is 4 single pipe runnin down to the flange where they merge.

Hmmm.... what that bronze line does do? The 4-2-1 does come with the ZL-VE as stock?

Villian you do that mod with yours? How it working so far?

hey, where can i get a manifold for d zm-de, u recommend the zl-ve one, where would i get one of those?

cinco, I was expecting one like that but there was nothing there. You can see from the pic, nada.

villain, i would love to do just that but i'm assuming that they're not too readily available. Is it a direct bolt up?

TurboDrive, its the EGR line. From what i understand, the EGR valve tends to give a bit of trouble with age causing some idle problems. Something to look out for i suppose.

Changed to K&N today

A

Removed the plastic intake piping as well.

Put back the "scoop" piece over the radiator as it was looking a bit empty.
I ended up leaving out the resonator box shown below

The intake box is now open to the air. Hot engine bay air for now.

If you think the plastic "scoop" draws in cool air, it doesn't. You need to look closely at where the bonnet closes, 1/4" to 1/2" in front the opening. Really stupid if you ask me.

There is a small improvement at around 3500-4000 RPM (100-140kph)
How much do I really expect with a filter and less plastic... Very Happy

Will either buy the CAI or make one but need some springs first. The car is extremely high.
Will go Megan from TSC as soon as the wife approves the funds.

big z u say u have a zm manifold, aftermarket or original, i aint want d original...lookin for a zl manifold 4-2-1 or a aftermarket performance manifold...lemme know what u have...

i scrap down my egr and cleaned it out
wasnt too bad sprayed some wd40 so its smood
i have to keep it because of emissions

Big Z · Posted: Mon Feb 18, 2008 10:19 pm Post subject:

Original manifold unfortunately...

villain · Posted: Mon Feb 18, 2008 10:47 pm Post subject:

me too i have an original manifold....i dunno if it better than the ones from the zl de....
yes the zlve extractors is a direct bolt up to the zm engine....and it working smooth....the engine not bawling like it used to do cause everything flowing free....sweet manifold...the man who scrap it say if he only knew what he was giving me he would have charged me more Mr. Green

but "we" were distracting him with some ole talk...

for the zl-de and zl-ve people i'll have an intake manifold to sell soon....u'll want that for your engine...

the bronze line does send back return hot air into the intake...
and yeah the O2 sensor does get move to the back of the engine...

the madness about to begin....just waiting on meh two harness...on the port still...giving trouble to clear.... Embarassed

will check seenaths tomorrow, for a zlve mani---, i hope villain aint usin no woman to disract men and take they parts cheap u know, ,,not that anything wrong wit that eh, jus that she might ask u to let she drive...

villain · Posted: Tue Feb 19, 2008 8:04 am Post subject:

that is why the car manual.....no woman except mommy drive it...
seenaths parting out anything? ...i think it was there it have a set of incomplete zl-ve and they not scrapping any?

TurboDrive · Posted: Tue Feb 19, 2008 9:39 am Post subject:

So I take it that blanking off the EGR line has no ill effects on the engine?

OK after doing some research I see that if the EGR line is clogged or if you blank off the line you will get a check engine light.

Villian your thoughts on this.

yeah villain, i gettin a zl-ve manifold for 750, how d price sound?, and d egr line have to be blocked or it could run back... lemme no opinions on d price asap, i dont want tomiss out on it

villain · Posted: Tue Feb 19, 2008 5:08 pm Post subject:

i got mine for 400 Twisted Evil

ent the erg line does help the car idle smooth or something....the ERG sensor is the one behind the throttle body after the tps sensor? if it is that need to be on and cleaned...if you see the carbon build up in mine....

but if it is the same bronze line we were talking about that goes from the exhaust manifold then you dont need it...i running it without one and the zl-ve dont have one...

so das a bad price den, where u get that manifold from ... i want one eh but dat price boy, it does line up direct with the rest of d exhaust pipes? and am what about the gasket, what to do use the gasket maker dat does come in d tube in conjunction with d old gasket or where would i get a gasket to fit there....? all d o2 sensors does plug back in, i want to get the manifold tomorrow and install on friday...need alot of info asap, any muffler dude can do it or need a mechanic?

villain · Posted: Tue Feb 19, 2008 9:34 pm Post subject:

the muffler people could make a gasket for you...the O2 sensor would not be in the same place anymore instead of being in from of you car is is now under and more to the back of the car...where the pipe comes down to one...better than when it was just sticking into one of the extractor pipes

ghostbusters · Posted: Tue Feb 19, 2008 9:56 pm Post subject:

anything else to know, i figure i go ha to buy it tomorrow...so u just block off the egr line and no cel light right, what u do, u crimp it or put somn to plug it, or just take out the whole return line...no cel ?

villain · Posted: Tue Feb 19, 2008 11:37 pm Post subject:

the muffler dude just crimp it and put a small weld on it to close it...no check lights..if he doesnt know about it just tell him seal it off...cause it does have a connection for it on the extractor anyway

when i swapped engines my old ZM had de EGR line from de manifold but de other 1 i put in didn't have it...

so i jus unscrewwed de EGR line and melted it shut and de car still runs smoothly

Strugglerzinc · Posted: Wed Feb 20, 2008 1:46 pm Post subject:

The EGR is mostly for emissions reasons. The valve opens at higher RPMs.

When the valve sticks open, it sucks exhaust gas at idle which makes for unmetered air causing a bad idle.
