turbo exhaust manifolds
 

Hi,

i'm looking into the available turbo exhaust manifolds, short of a custom jobbie.

I see CNK and KORE, pretty much same, stainless steel,
external wastegate port,
and the old Champion manifold from korea, not sure on its
wastegate options.
T3/4 flanges are OK, but not essential.

are there any others about? What are most boosters
using?

cheers

sup bry... well yea many are going with the KORE and CNK manifold, they look kewl in the engine bay, and perform good... The champion used to be one of those that many wanted to use, but it was a hassle bringing them in, and we thank CHEUK for it but I feel many are done with that one... the Alpine one is a log type like the champion and I think is only offered with their kits, can't be purchased separately...

And there are those out there that are incorporating the mitsu manifolds to the 2.0L, but I've only seen one done on an accent if I'm not mistaken...

but that's all I know

it was a beta i belive..

If I remember right, the guys using a mitsu manifold had the pipes line up right and almost all the holes. They had to enlarge a couple of the bolt holes to make it fit.

Which begged the question: what happens during thermal expansion? I'm not sure if that was resolved, but I vaguely remember the discussion.

I may be selling my old manifold as well. It's new, from Onpol's shop, sized for a T3 turbine and Deltagate. My turbo project's on hold indefinitely, and I may just go ahead and get a kit the second time around. Shipping to Oz might be a pain, though.

I've had good experience with CNK, too. Good quality work (did a downpipe for me).

later,
ac

hey, thanks.

I cant get any in oz, so shipping from the US is part
of my costs.

Bat, do you mean log as in cast iron?
How does the CNK manifold hold up under thermal
expansion?

I remember Onpols manifold, from memory it had very short
runners and the flange was vertically mounted.
Is that the same as yours?

thanks
bry

Bry, you might want to try CAPA. I know they sell Alpine's kits in Australian under their name, and I thought I remembered seeing the kit on their site.

bry, I'll take pics this weekend and post them.

Short runners, turbo hangs vertical in the center of the manifold. Wastegate port comes out the top/middle at a 45 degree angle upwards. not sure of the metal, but it was thoroughly coated in high-heat paint (outside).

Sorry Bry, I have the KORE one, so not sure on the CNK, but as of now, I have yet to see any cracking, any warping from expansion at all in my manifold, and we inspect it carefully... smile.gif

I didn't mean to imply that the CNK, Alpine, KORE, or Onpol manifolds would crack under the thermal loading. They are made for the Beta's pattern of bolts.

I think the old discussion was: if you drill out a Mitsu manifold to make it fit, would it be too tight on the studs and cause problems when it expanded?

Sorry if I caused any confusion.

Curtas I was more curious due to the stainless steel
nature of the manifolds.

I'd be keen to see your pics, thanks for that.

Hey Bry, long time no see. You still have the coupe hey. I think silverwater automotive might be able to help you out with a manifold.

Hey John, yeah its been awhile, still got car.

I've been trying to steer clear of silverwater, some of their
prices/charges are astronomical!

you still got the same car?

Bry

bry,
Here you go. It's a bit tough to see the wastegate flange, but it's there in the center.

Flange is sized for a T3 turbine. Wastegate is sized for a Turbonetics deltagate. The manifold is completely new (never mounted). I can also sell the wastegate, but it is used (was on Onpols first turbo buildout).

edit -- added pics that show the wastegate and side views. Unfortunately, the gloss black doesn't show up that well.

Bry, here is the difference between the KORE and the CNK manifolds.

The CNK manifold utilizes a collector in the end of the manifold while the KORE manifold does not. By having a collector at the end, the flow of gases are able to have equal pulse lengths.

The CNK manifold is designed to hold up to a great deal of heat. The flanges used on the CNK model is made from Mild steel while everything else is stainless steel. This is good due to the fact that the manifold will be allowed to stretch/expand from the heat while being very good at combating warping of the manifold.

Both, KORE and CNK manifolds are the only options I would consider if I was you. Both are of high quality, great style, reliability.

(Although I would take the CNK over the KORE. I may be just a little biased :D )

Wow those are some fine looking manifolds.
Yeah Bry still got the old girl, havnt done anything to it for a long long time.
yeah silverwater are expensive for sure but what they do, they do right. unlike some other so called hyundai specialists in sydney.

xtreem..
was that your car that was in hot4's mag?

Yeah mate thats my car.

I just spent a week down the coast there, f**ken trawlers
have ripped the beaches clean
nice to see it rains on my holidays!

Hey Bry how about taking another holiday then as we need more rain badly. lol

boss wont have it.
i caused one problem and fixed 3, so i'm ahead so far wink

You done much to your car since i seen it last???????? did you end up getting the haltech???

nothing exciting, no
i didnt get the haltech due to various reasons,
hoping to get one this month

guys, use email for your personal conversations.
