Aftermarket Headers

[e30polak]

Also, Polak...I am trying to understand. So you put 3/16 worth of washers bewtween the passenger side motor mount and the engine arm?

Yup. Make sure to either flatten, or remove the body side heat shield on the passenger side firewall.

he may have a point. Stress one end, and the other end could still crack, it all depends where it puts load. Headers are not meant to flex at all. Maybe you could take a few pics of your setup?

I didn't get my exhaust done yet, i still have open ebay headers, and they look dangerously low. I'm not sure how it's going to turn out...

I was wondering that at first but one of the guys I used to work with said it would be fine. He has been doing welding for over 30 years so I trust his judgment. It really isn't alot ether but just enough to clear them. The problem with shimming mine was each time I would add one to that side it would raise it and then instead of rubbing on the cross member if would kit the bottom of the cabin.

I did. I had to heat the crossmember up and beat it with the ford tool till it cleared.

For something as important as that crossmember, which supports the engine and the lower control arms, is that not sacrificing some structural rigidity there?

And this is not to be offensive by any way I am genuinely wondering.:)

I believe you, it's just weird why it's happening to some of us and not others. I probably wont make it to the picnic, I'm too broke. :(

Aw that sucks. I dont know why this is.

[e30polak]

And you think I dont :p but mine has no clearence for some reason. I have no clue why. None of my friends who have swap cars had to space them so I dont know. O well its done now. If you come to the picnic I can show you. You wont believe it.

I seriously have 3/16ths clearance from the sub-frame. Since I flattened the firewall heat shield i have no contact there as well. It is tight, but the headers have show no indication of rubbing or hitting the sub-frame, and I drive th hell out of my car on a daily basis! :-D

It was spaced but when going into a turn they would hit and cause vibration.

WTF??? Are you guys spacing the passenger side of the motor? I put 3/16ths worth of washers on the passenger side and have no clearance issues. It's close, but no rubbing or hitting on anything.

You're talking millimeters on 20 year old cars. I can fit a sheet of paper both between the suframe/header and between the body/header. Probably couldn't fit 2 sheets. It probably hits under load.

Hey anyone with the Ebay Super sprint replica headers in their e30 having issues with one of the headers making contact with the engine crossmember?

[SamE30e]

i have neither of those.... the ones i had were 2 piece, kinda a hybrid between the 2 you posted there.

Same ones I have, they look low but my car is stock height for now so I can't tell.

Dude! I am having this same issue right now!! the O2 sensor won't go on header 1-2-3 because fuckin' header 4-5-6 runs into it!! Where did they come up with the locations for these bungs!?

Same problem, I just added a bung after the headers before the cat.

[WADE30]

Yeah, they look like the ones I got which look like the ones you got. Mine are a pretty big pita though because the O2 sensor bungs are in shittarded places. One will hit the other header and the other will jam into the firewall. I'm going to have to get a bung added elsewhere. It shouldn't be a big deal going a couple feet farther back though. Stock position for the bung on E34 and E36 is at the y-pipe just before the cat.

Those are my headers. See the resemblance?
