I'm thinking the right one is a greddy because the part that normally has greddy engraved on looks to be grinded off and is a lot smoother than the rest of it. I'll look through my emails and find whomever sold it to me. I think it was someone from the miata.net forums

 

weird...looks like a greddy but the flange is obviously different...

you say you bought used, was it described as cracked?

 

it was described as cracked, but the turbo was in great condition and it included an intercooler and piping for less than $500 from what i remember.

Flang cut off, and a 1.8 flang welded and ported onto it will be my best bet...

There are no shops carrying a greddy replacement manifold for the 1.8...
You can see some welds...

As the 1.6 has a bold in the middle of the runners, the 1.8 are off center...

 

acutally the flange does look welded on...

 

I'm totally confused. You have a 1.6? You have a used Greddy kit that has a busted up manifold for a 1.8. You have a ETD Greddy replacement manifold.

From the picture, the bolt pattern on the other manifold that isn't cracked looks correct for a 1.6. Is that your ETD? Does the ETD manifold fit? If so, why worry about the other manifold?

 

'cept Greddy never made a manifold for the 1.8. I think everyone is just curious as to what the cracked manifold is.

 

A paperweight? :gay:

Yeah, my vote is for a modified 1.6 Greddy manifold.

I have the ETD replacement and I love it. My only complaint is that, on the website, ETD says they have them in stock and ready to ship. They seriously need to update their status.

 

i'm pretty curious too what exactly the guy sold me. the etd is purtty but i was slightly dissappointed. it took about 7 weeks to get it, and i need to take it to a local shop to fill a hole they missed. still, i'm happy with how it looks and the reputation it has for not cracking.
