Hm,

as soon as the story breaks I might break down and get myself a decent muffler after all. I have to start working on the HE's anyway pretty soon and loose the stupid flip stud adapters. They leak and I lost one countersunk allen screw already. Now they leak even more. I'll have a welder cut the flanges on the HE and rotate'em 90 degress. Much cleaner solution.

Still other than on long drives the sound of Pauls old setup (glasspacks) on the stock 993 HE's is hard to beat. Under WOT it sounds like an attack plane. I was also told you can see some faint flames during shifting from a guy that rode behind me once. :D :D :D

Now you tell me they leak :D
Well at least I don't feel bad that the ones I bought from you leak too. At least I have the winter to try and come up with a better solution. I think Kevin Stewart on the board has a jig to allow you to flip and reweld the HE flanges.

Todd

todd,

mine didn't leak at first. Thing is that I lost one of the allen screws at some point and now they leak.

You don't really need a jig to flip the flanges. Just bolt the left HE to the right HE when welding it up. As simple as that. Then you only need to make sure you get everything aligned tilt-wise for the weld.

Ingo

Embs--weren't you going to go turbo?

Yep, still am. I am looking for an 89 (The best year for the 930 IMHO) Once I find one (that I can afford).

Ingo

I'm sure you don't but I find it easier to weld with them off the car, and the jig would allow that I believe.

The one adapter stud began to turn in the aluminum adapter and as such didn't tighten up very snug, so I'm sure that is where the leak is. I think flipping the flanges is a better long term solution.

Todd

What are you guys doing with the 993 HE's? All of the 993 engines I have seen have the heads drilled and tapped for any configuration? I am a little CORnfused...

OK guys i have a jig to lip the flanges if any one needs it, Kevin

They are installed on 964 engines, as such need the right side flipped

Todd

Todd,

what I meant is that you take both HE's off the car. You use the uncut HE (drivers side) as the jig and bolt the cut flange piecesof the passenger side HE to it. Then you align the cut HE to this setup and weld the flanges back to the cut inlet pipes.

The driver side HE serves as your jig basically. You just have to make sure that the tilt along the input pipes is close to or ar zero. Does that make sense?

The basic flaw of those flip stup adapters is that they are too soft. When you tighten them too much they bend and you loose the seal. The crush gaskets are very soft and don't require much force to compress and seal. But not torquing the srews very much causes you either loose them (ask me how I know) requires to glue them in with locktite. I didn't like that idea either.....

BTW: Are you still interested in the Dual-chip?

Cheers,
Ingo

So, whatever happened to your built 3.8? :confused: :confused:

Have you got a 2nd car now? :confused: :confused:

the jig i have has a piece of angle welded to to keep it flat,,,, the take one off and weld it to the other doesnt work, Kevin

Ingo

That makes complete sense, I think I will still try and borrow Kevin's jig, maybe it makes it easier to keep all of the flanges in plane with one another.

I still want a chip but since the car is put away for the winter it isn't really pressing and will have to wait until after Christmas now.

Todd

on the jig you take the HE and use a dremel or die grinder inside the HE to brake loose the flange, you then bolt the flange to the jig and weld the pipe back in, the trick is to not grind any of the header pipe away, you will be suprised how easy it is, Kevin

The 3.8 is taking a break, the 3.6 is going to be in the car for a little while (work the bugs out) then it is being traded for work on a 930 that I don't even have yet!! More confused...Then the 3.8 will go back in the car and life will be back to normal!

Kevin,

do you have a picture of your jig. I am still puzzled as to how it is different from using the other HE as the jig. Both should be able to keep the flange surfaces in plane, right?

I like your idea of cutting inside the header pipe. That makes good sense.

Ingo

Thanks! That clears it up. Keep us updated with plenty of pics... ;)

ingo we tried the bolt them together no good back wards, Kevin

Ingo is just waiting for my lift's floor bolts to be installed so he can get to the HEs.....he doesn't want to be the 911 pic of the week like that corvette guy......

Did not see the vette guy. What's the story??
