Direct replacement to Greddy manifold
 

Hey... I've been searching all over the forum since I registered for information about that *"!*% greddy manifold. I just bought a 1990 Roadster with a greddy kit with fmic. About a week after, I started hearing an exhaust leak and found out about the crack and how (on this forum) they just all do it..

EVERY thread (they're quite old) mentions the ETD manifold as a replacement... Are they still alive? The site seems down since may... I found the BEGI manifolds, some ebay ones, etc... None of them seems to be a DIRECT replacement to the greddy one... They all have a curved flange, while the greddy one is straight up...

Could someone please help me find some model (new/used) that will fit there, and problem solved?

Thanks a lot... (flaming suit on)

yeah they dont appear to offer any manifolds anymore.

You may want to see if artech (site sponsor) could maybe make a replica for you.

Thanks, I'll take a look. Would this one fit? It seems to be straight up and "better" than ebay ones... but no year, no fitment chart, etc...

dunno much about that one. could be an HKS replica.

It's a t25/t28 manifold, so it's not going to work with the greddy turbo.

the GReddy turbo has a t25 footprint...

That is definitely not an HKS copy. My HKS has the outlet centered between cyls 2 and 3.

That looks like a strait up GReddy copy.

Random pic I have of my GReddy manifold.

Send them a request for a larger picture or a drawing. It certainly looks like my GReddy.

Did that yesterday... no answer yet.. Would be cool.. Can't find anything else online... Got a friend selling a full engine/tranny/turbo kit, but don't want to buy the whole thing just for the manifold...

And yes, it surely does look like a greddy one...

Weird, I thought it used a mitsubishi style mount. My bad.

Did you get a reply in the end?

Nope... ended buying a full block with 2 tranny that the same greddy kit on it hahahaha ONLY for the manifold

I got my replacement for the GReddy manifold from Artech, love it, much flowness.

How well do they fit? straight swap and bang all done!

Interesting!

I'm also looking for a new one.

My manifold seems to be growing in width, so its getting fixed on the studs, weird...
This is the second time this happens, first time i had to drill the holes bigger to fit again.

So I stay busy until my studs break, I'm afraid :vash:

yeah, had to get a crowbar in there to take mine off, just keep drilling the holes.

This happened (notice the cuts between the runners closed up over time too :

Yes indeed, i also had to use a crowbar to get it off.
I don't want stay drilling the holes, like your manifold.

You mean this Artech?

There is too little information on this site about the manifold, so i have sent them an email, and still waiting for a response of them, maybe i'm too impatient..
