Extractors

[Goon]

Hey

I just picked up VK 3.3 202 "Was chrome possible black" extractors for my VC 3.3 202 "Blue"

Any tips on installing these, i looks like my mainfold is connected to my exhaust, woud i remove this as well?

sorry its thr first time ive ever put something like this on..

Gday, the extractors (tube headers) might have a flange on the end of them? Do they? If they don't then you would want to put a flange on the end, by flange I mean a metal welded plate on the end of the headers and you'd want the flange on where it connects to the main pipe also, then get a good extractor mettalised gasket to seal it up.

First of all let us know what you have. How was the old manifold mounted up?

Access to a MIG welder is almost essential to do a professional job of things but it is a bit gray at the moment and need a bit more info on what the pipes have or not whether they have flanges or not.

From experience, DON'T directly weld the tube headers onto the main pipe. You will want to take the headers of at some stage. In all cases any welding should be done by a MIG welder as arc welders burn holes in thin metal more than anything. MIG welding can go down to 1mm thick in most cases and it is a great thing to have in the workshop.

Have you thought about asking around some local places to get them to weld it and install it? It probably won't cost much as it's a pretty simple enough job.

I can get a hold of a Mig welder no issues there..

I'll post pictures later on tonight of the current engine area and the extractors.

[Goon]

Here's the pic, i couldnt reall get a good picture of the engine bay yet, ill have to wait for daylight and crawl under to takeone i guess.

Anyway i got these from the wreakers, i'll hook int othe outside of them with rust converter but yeah :P

[craigvk]

They look alright but you didn't say if you had flanges. If you have access to a MIG, then all you need is a pair of flanges, flange gasket and a gasket for the headers at the exhaust. And maybe access to an oxy if you need to bend the pipes a bit to fit

[Goon]

Cheers mate

I'll let ya know and others on how this works out

[ucwepn]

The manifolds are bolted together intake/exhaust. you need to remove the both of them and remove the intake from the exhaust. Then you will need to seal the hole in the bottom of the intake manifold ( a bolt does the trick). then get your extractor gasket and put some "gasket goo" around the dges of each port front and back. then get the extractors and bolt them to the motor. then join the flange to the rest of your exhaust (if the flange is still there, it may have been cut off) If it has been cut off take the car to the exhaust place and get them to weld it on to your exhaust or weld a flange on it for you.

Goon, I've done this before with a red 3.3 in a VB.

I did pretty much did what Ucwepn said and worked ok. The only thing id suggest before sealing everything up is to do a trial run first bolting on the extractors and inlet manifold to see if they fit. I had to modify the inlet manifold a bit because the VK extractors didn't fit with the VB manifold.

You'll notice how much better it runs and sounds once its done.

[Goon]

Well the cars almost ready for the roadworthy test, would i still have a good chance of getting it registered with the extractors? or maybe i'am better off waiting till after ?

[craigvk]

If the headers are mounted on properly and they aren't leaking, they should be fine. Don't get upset if the rw doesn't pass the first time. It never does. Before you go, get under the car and check some of the bushes aren't stripped out. Replace them if you can if they are really bad.

[Goon]

Well i went into supercheap today to look for the extractor gasket and the only one's i could come across was Holden 6 red motor extractor gasket, though by having a look at it did look like it might fit

Is it possible to use a red 6 extractor gasket?


There looking alright now, but i expect the rust converter will burn off

[ucwepn]

Hmmm I'm trying to think back to my red 202 and mentally counting the ports and where they are.

Actually looking at the pics of your extractors the red gasket does look like it will work, my only concern is if the locations of the studs are the same on the blue and red.

[craigvk]

There looking alright now, but i expect the rust converter will burn off

Get a $5 wire brush drill attachment from Bunnings and give those headers a cleanup

[gd81]

You'll need a blue/black manifold gasket, as the ports and bolt pattern are different compared to the red.

[Goon]

Thanks lads

Well i'll post the final pics soon, speaking of that..
Anyone know an easy solution to cracking the exhaust nuts, holding the exhaust pipe and the exhaust as one.. I don't think these nuts have ever moved.. which is making it a really tough job to do

[Spike79]

Try a length of metal pipe over the socket handle, this with give you heaps more leverage. I picked up a 2foot peice of pipe and i don't know what i did without it, probably a lot of cursing and swearing and a few busted knuckles. Put some wd40 on those nuts(exhaust) and let it soak in for a while too.

How much would it cost to get extractors and sports exhaust installed on a blue 202? If I get them, I don't think I'm capable of doing it myself.

[Goon]

Cheers spike i had that in mind as i do the samething for my oil plug, but i don't have a metal pipe atm..
I know how it feels on the knuckles to lol!

spd_dmn : How much would it cost to get extractors and sports exhaust installed on a blue 202? If I get them, I don't think I'm capable of doing it myself.

- I'm not sure on the real cost but i do know but not doing it yourself, you will run into labour costs which may go into the hundreds...

But atleast you know the job is done right...

- Doing it yourself which is the cheapest way, from my experince so far i've only spent $80 for the extractor, $25 to buy the items to give it a good clean up, $20-30 for the gasket if i search for the cheapest price.

Flanges are like $5 each if needed

[DANNY8]

The bolt pattern isn't too much out. The last bolt is a few mm out but thats about it. I put red extractors on my blue motor and I just had to use a bit of force to move the last pipe to fit on the stud, not very much at all. But don't put red ones on ur blue motor coz you end up with lots of leaks LOL!! I have a set of an vk efi 6 to go on, so hopefully when they go on i should be fine.

Most of the stuff connected to the stock headers I didn't worry bout putting back, but coz I'm no mechanic I'm still working on it fixing up vacuum leaks etc etc lol. It's a bitch on a cold mornin when the auto choke turns off, coz it idles at 600rpm and it stalls if its still cold unless I keep the revs up a bit :P

Here's a before and after of my engine bay, and also have some pics of the extractors as i was puttiing them on.

I've also painted them red now

[Goon]

Nice mate , does the car run great now?

You really should buy a few cans of degreaser

I like your aircleaner the nose looks extreme, may i ask where abouts you got that from? Or is it a mod made by yourself?

I should have some pictures of my job soon, once i finsh it off.
Been working on other areas of my car atm .

[DANNY8]

Thx mate, well apart from the ticking and popping from the extractors leaking, it runs a hell of a lot better. I was told the power increase would be barely noticable, but I'm bloody pleased with the difference. It builds up revs a damn lot quicker now and overall just runs a lot better with them on.

I degreased the engine when the intake and exhaust manifolds were off.....although it's a hell of a lot cleaner then it was, there's still crap everywhere, lol.

The aircleaner is the same one that was on it when I bought the car just over 2 years ago. As far as I know it's just a stock one.

I'll put my new set of extractors on soon, but right now I have to find and put in a replacement diff. I blew it friday night so that sucks....but hopefully I can find a VL diff to chuck in

[figjamidhVK8t4]

how did u connect extractors to exhuast did u use a sleeve n clamps or get it welded...reason i'm asking this weekend i'm working on my vk such as changing head,central locking, and i'm converting to an aussie4spd so i was thinking about throwing on the efi extractors that i have if they will bolt straight on.....cheers

[DANNY8]

I got mine welded up, but my efi 6 extractors has a flange, so I'll be bolting them ones up. I've also got a new peice to go from the flange on the end of the extractors, down to where the box use to be behind the diff, so I'm also replacing everything in the middle.

As long as you have a blue or black 6, ur efi 6 extractors should fit.

Goon: Here's a link to an aircleaner like mine on ebay. So far it's at 99c with over 3 days to go, so check it out.

[Goon]

Cool thanks mate I'll test my luck..

Just brought the gasket today after i searched everywhere and could only find one at Repco

[Goon]

Hey all

I'm just about to weld my exhaust to my extractors in the next few days, though would anybody be able to tell me if 4 advice do i block the 2 holes under the mainfold with something? or not?

Thanks
