I have a 14b turbo on my civic. I have the HF cast iron manifold. I just found a manifold that looks like it would probably be better than my current manifold.
Would this increase my horsepower like it says it would? It sure as hell looks alot nicer!
Suggestions?

EDIT: I'm actually now looking at these:

Do either of these manifold really gain hp over the hf manifold? Is the first link i posted worth the extra 30 dollars after shipping?

 

They look cheap to me, stick with the manifold you have.

 

both of those are more than likely junk. You're better off with your HF manifold, it will put up with tons of abuse. Just get it jet-hot coated if you're worried about how it looks

 

Ok and i was looking at my car I don't think the manifoldwould fit because of some piping for my turbo.
If those manifolds didn't crack or anything, would they give me more power over my hf manifold?

 

who knows....get one, get it dynoed before and after and tell us. I personally wouldn't buy that, but that's cause I can afford to buy something better. It might actually show an increase in performance...

 

Well the problem is, thats the only manifold I have ever seen that is for a d-series engine and a dsm turbo (14b). That 2nd link so far looks like the best manifold out of the two because it has a lifetime warranty against cracks and defects. Where could I find a manifold that will give me better performance?

Also I have an adaptor plate welded on so the HF manifold will fit. Is there anyway to make this manifold fit?

 

send me your hf manifold and i will port it out for you. make it flow a little better

 

I would love to, but the problem is I wouldn't be able to drive the car without the manifold...buying another manifold and having to pay for my current to be ported would be expensive and seem hardly worth it, especially because the adaptor plate wouldn't be able to be ported because I can't take it off.
How much of a power gain could I see from having the manifold ported? Shipping would be very expensive.
I'm wondering, even though i have an adaptor plate welded on, do you think a shop could get it off so I could have a manifold that fits directly to the turbo, like the manifolds I linked?

 

Don't trust ebay warranties, most of the time they are fake and they don't back them up. If you want more power get a boost controller and turn up the boost.

 

if it cracks you can weld it back up....just get it dynoed before and after, it's the only way to tell.
