Hey whats up guys i was wondering if any of you guys are running and hks cast iron manifold on a 1.8 miata. My question is if you are running it can i see some pics of it cause i just got one and it doesnt say hks on it anywere so i want to make sure i didnt get hosed. Thanks in advance.

 

post a pic of yours and we'll tell you, only a few members here with an HKS manifold and they dont post much.

cjernigan has one IIRC.

 

How about you post pics of yours, i'll tell if you if it's an HKS.
Here is what it should look like though.

 

i also ordered mine, got it from racerwheel. It does look like it, but does not have any stampings like yours does, thats why I also was wondering if it really is an HKS. I will try to post pics of mine when I get home.

 

nice mine looks exaclty like that one thank you guys

 

My HKS came on the car. It doesn't have relief cuts and it appears to be welded on the bottom. You guys might want to make relief cuts between runners 1-2 and 3-4. Vertical cuts right on the bolt hole. That will relieve some stress and help keep it from cracking. That is common practice amongst the Greddy manifold users and their manifold is very similar to the HKS.
