Stock Exhaust Manifold

[l_uk3y]

Hey Guys.

Just another quick question before i bolt the new turbo in place. My factory Manifold is looking a bit worse for wear (Not leaking or anything though). Corroded away along with most of the bolts in it being stuffed. (Part of being 13 years old i guess)

Option 1 and the easiest - Leave it there pretend it isnt corroding and worry about it next time there is a problem. (maybe something could spray with to help protect the new bolts i will be putting in??)

Option 2 - Take it off (will be a nightmare i am sure) And replace it with a new Factory piece. If this is the case would it be well worth looking into ceramic coating? and would there be anything else you can do to improve the factory manifolds performance.

Option 3 - You tell me what this option is. If replacing with a non factory manifold it would have to line up like factory on both ends as well as sit in the factory location. i have ZERO interest in a himount setup.

Cheers for any help.

Are you talking just some surface rust?

I cant imagine it being much more than that, which is nothing at all to worry about.

The manifold bolts - this is common after 10+ years. Just replace them with better studs and away you go mate.

You'll probably break a few, its easier to call a mobile thread dude to get them out - trying to do it yourself is the pits

Yeah its just surface. Just whilst i have access to it i might as well find out if theres a better alternative. i.e the caramic coating that will be better for me in the years to come

If your super worried about the rust, get it sand blasted. Then ceramic coat it if you want it to be pretty.

I'd also port match the thing to a set of new gaskets, then clean up the casting marks etc ( on the inside ).

better in what way?

performance - no real gains at all to coating, porting etc. Just added expense for a gain that is debatable.

It's a factory manifold which im assuming has a factory turbo (or similar small item attached).

looks - well coating or something will make it look better... but then you have a heat shield over most of it so unsure what advantage that has at the end of the day as you should always run the heat shield

Where are you located Luke. Would cost around $30 for me to sand blast it. normally around $50 for 'non' sau people.

[l_uk3y]

Located in Bendigo Central Vic.

Thanks for answering. I shall stick with the existing manifold as it is at the moment, except with some new bolts. Yeah i still have the cover so im not fussed at all with what the manifold looks like.

Concern Solved.

Here is an example of mild steel that i just sand blasted so everyone can see what rusted steel looks like before and after.

[R31Nismoid]

How long does it take to go back to the way it was?

6 months?

[boostn0199]

dont worry about it just if you are going to do something replace the studs and gasket if the turbo is off atm so that if you do get a leak dont have to take everything off again later on

Theres a tool you can get that makes it very easy

i think its called a thread puller or stud puller, can get it from repco, never know when it will come in handy

was that a question for me. if so sand blasting is a surface preperation. so all depends on if it gets coated or not.

generally most people just want the surface cleaned up and thats it.

Debateable. I know there are easy outs etc.

But read the threads here about people that have attempted this alone, and ended up calling someone out the next time etc.

It costs very little per broken stud. Consensus usually seems to suggest pay the $100-$200

[boostn32]

yeah good question, like most mild metals left uncoated they will rust, touching the steel with sweaty hands will bring

the rust on quick. i would say you would get 6-12 months on a exhaust manifold before it rusted again. but if you lived

close to salt water that could speed things up.

I charge around $40-$50 per broken stud. that's the price if you dont touch it, if you have had a go and cant get it you could be looking

at around $60 a stud depending what you have done, and if you have snapped a drill bit or easy out in there as well,expect to pay around

$100 a stud. and these prices vairy depending on the access to the stud as well.

gotta love it when they dont tell you that they already snapped an easy out in there makes you just want to smash skulls sometimes!

So so true, only one word comes to mind when you see someting else snapped off in there, F*#K

haha yeah, thats the one word that gets said after the whole "what the f$$k, why isnt this working like normal, that should be coming out, what the f$$k is that there, Ahh F$$K" than its followed by "useless F$$king c$nts that don't know what the f**k there doing"
