ebay cast iron top mount issues
i began to port match the runners when i immediately noticed this issue
if you look at the port on the left, you can see the gasket wont get squished between the flange and the head, i fear this is going to blow the gasket out.
some ideas ive have is to slot all the holes for the studs to center all the ports ans get a good clap on the gasket....
or weldt more materal to the flange and grind down flat to create a larger area for clamping.

Holy crap! I'm soo glad you posted this... I was looking into one of these for temporary use. Now I see that isn't a very good idea.
My first thought was also slotting the mount holes, but even then you're going to have so little material in front of the first runner and behind the last runner. Looks like an 1/8" right?

I welded more material on mine. I forgot about this.

I was going to suggest the same thing. Prob needs to be resurfaced anyway. Man that's a lot of match work!
Not to treadjack, but is the single cam version just as bad?

Here is mine. I did not mind cause it was a cheap mani and I wanted to test out my HX.

Thanks for posting this, i have one sitting on my table here that i have been meaning to port out.
Im going to be doing the same thing plus maybe welding on an angled flange to make it a bottom mount. Just giving you an idea

Did you guys port your head already? It wont leave a lot of room for gasket seal but should look like supas
My ports are stock and ive got a bit of room.. you can see where the rtv squished up into the port and then came off
You can just slot the bolt holes a little and have the manifold hang down if it truly doesnt line up well

Re: ebay cast iron top mount issues
i made 276hp 280 tq with this manifold unported in my ka. after 2 years it started to get hairline cracks(i bought a cast to avoid this too!) then finally saved for a better manifold never looked back

Re: ebay cast iron top mount issues
Damn.. MY manifold is getto but at least it all lines up lol..
I will think twice before buying an ebay manifold.. who else makes cheap manifolds for SOHC ka's?

Re: ebay cast iron top mount issues
I've had a RevHard (what the ebay cast manifolds were copied from) on my car since 2001 with no cracks (so far!)
Do not slice the reinforcement bar between the runners. It keeps the manifold from trying to twist.
Slot the bolt holes like the stock manifold to keep it from cracking.

Re: ebay cast iron top mount issues
still think this is the best budget build option out there. just had my younger buddy get one of theses. 80$, gotta work with a budget. freeing up 300$ worth of manifold gave him money to play with elsewhere, like going for nismo injectors over DW. or being able to afford nistune. we'll grind the ports square and weld on some more to the flange for sealing. flex pipe as closr to the turbo as possible and a few years is cool with me.

Re: ebay cast iron top mount issues
I agree with you daigle. I've been running that cast mani for some time now. The ports are definitely not matched to that ka head, which is weird to me; but its worked well so far with no leaks. I think if you port match the Mani, you will get better flow and faster spool time.

Re: ebay cast iron top mount issues
all im saying is there is another design on ebay that is $99 with much bigger ports and lines up well.
the disadvantage is the turbo is closer to the bmc.
nevalift had to revert back to this one after upgrading to a ebay t3/4. he did slot the holes to move the mani over the port and its working great.
