Extractors? how to tell red from blue

[veeque92]

Hi all. was just wandering if someone can tell me how to tell the difference between red and blue extractors.
I have a set sitting in the shed that I bought for my blue motor but not 100% if they are for blue.
Also, there is a small flange welded onto one of the pipes was wandering what this was for.
Thanking you,

i dont think there is any difference performance wise and i think red or blue extractors would bolt on to either.

what color are they if any?
and i have no idea about the flange

I'd think u would have a hard time fitting red ones on, so if u have a blue motor and u fit blue/black they should just slide straight on..

the red ones require bending the end pipe closet to the enginebay firewall to fit.

Id only fit blue or black extractors on blue and black engines, fitting red ones is a waste of time.

You say u have a flange welded on... maybe there from efi ?

[frenchyvh]

From what i know, they are different extractors, the red motor has a 9 port head and the blue has a 12 port head, the blue's usually have two extra pieces of steel welded in the top of them to brace them as well.

Mine fit straight on from a vk "black" to a blue motor, manifodl fit no worries even when i put the vk manifold on. just needed the extractor gasket and that was it.

hey mate, i think tere for a blue or black motor bacause the small flange sounds like its for anti-pollution gear which the red didnt have. but im not 100% sure on this mate.

The blue and black carby motor extractors had 2 flanges which bolt up to the bottom of the intake. My EFI extractors only had a single flange which came off the first pipe if I remember correctly (haven't seen them in a while ), which connects to a pipe which then connects on the intake just under the throttle body (I think...I only now this from having a basic suss at an EFI engine). The red motors had no flange.

So if urs has just one single flange then possibly there EFI extractors, which will bolt up to ur head, but the intake won't fit back on, If u post a pic we can make sure, coz the EFI extractors had a different sort of setup then blue/black carby extractors.

As for fitting red motor extractors onto blue/black heads.....yep it can be done. Like Goon said the last pipe needs to be forced over a fraction so the bolt will go in the hole....only a few mm's tho. Also I had to grind a few small bits off the flanges which bolt up to the head, coz when I put the intake back on, the flanges hit the extractors flanges, so a smallish bit of grinding and that problem is fixed to. Yes the red motors are a 9 port head, and blue/black a 12 port, but the only major different from them is the intake ports...instead of 3 intake ports it has 6....exhaust ports are basically the same.

I was using red motor extractors on my blue 173 for months.

They have the single flange on the front pipe like you explained mate.
So does this mean that they are unusable for a carby blue 202 or Can i block off the flanges in the intake or run a pipe from it or wont it even bolt back on.
Thank heaps for the help

[DANNY8]

The holes on the bottom of the intake wouldn't need to be blocked off I wouldn't think. But yeah they won't fit anyways if there the EFI extractors. Basically the pipes on them come out further then the carby extractors, which in return interfere with the intake manifold.

I'll find a pic of my EFI extractors, and if urs are the same then they're obviously EFI extractors and won't be useful to u unless u go EFI.

[Goon]

I thought ucould use efi extractors on a carby by blocking the efi pipe off?

[DANNY8]

Nah EFI extractors can't be used on a carby motor. I tried it and the intake manifold wouldn't fit back on, the extractor pipes got in the way.

Here's a pic of my EFI extractors:

The flange on the first pipe has been welded up. As in my pic, pipe 1 and 6 join into 1, 2 and 5 join into 1, and 3 and 4 join into 1, then those 3 join into one. If urs are the same then there EFI extractors. All other extractors are setup different...I've only seen cheap red extractors and blue genies, but I got told the EFI ones were different from the rest due to that pipe setup.

Here's a pic of my "NOT EFI" extractors off a VK 202.

[veeque92]

Bugger me thats what I got. If anyone in adelaide has a set on non efi 202 Blue extractors they want to swap let me know.
Cheers for the info everybody.

I thought the carby blue/black extractors had the 2 flanges which bolt up to the bottom of the intake? The Genies we got on the skid wagon have them. The only extractors I thought came without the flanges were the red motor extractors?

go to a wreckers or upullit and u should find a set without to many hassles

I pulled them of a VK at the wreckers, they where in worse nic then they look, i clenaed them up but still have to paint them someday real soon.

Everything slide straight on no worries! even when i installed the vk manifold it was an even better fit. "extractors on first then manifold"

I've never seen extractors that bolt up to the manifold? no air comes out from the manifold in the 2 intakes under it, those intakes work with the old exhaust for pre heat.

I guess it's just the 'brand name' aftermarket extractors which have the flanges for the bottom of the intake. The Genies we have has them, we didn't bother bolting the flanges to the bottom of the intake, and as we killed the rings during the skid comp not long ago u can see smoke coming out of where it was suppose to bolt up haha.

I'll get a pic of them a bit later.

cool man, it's good to know the different types of extractors out there for the 202's!

i've watched a few of your videos i like'em
