Air pump removal and modifications

I have been thinking of removing the air pump and ancillary equipment on my '87 930.

I recently dropped my heat exchangers and boy what a ***** it was getting the studs and barrel nuts off... So my question is how bad and what issues will I face with the removal of the air lines which feed into the exhaust head...are they easy to strip.. can they be heated without damage... I know I have to plug up the holes. where you able to remove the lines without detroying them (I will want to be able to return the car to stock one day).

Also removal of the air valves and solenoids...issues concerns.

Cat pipe should I leave it on and plug it or get a replacement pipe.. ( I am not to concerned about emission issues where I live).

Lastly if I remove all this stuff ... should I leave the Lambda and frequency valve alone or would I need to do anything... gut feel is leave it alone... thoughts...

Thanks

I ruined those tubes for the air injection when I removed mine. The air injectors came out of the heads fine with no damage.

Peformance products sells purpose made injection port plugs that go in place of the air injectors.

jwmarc, the only thing I have ever done when removing all the garbage was take it off and plug all the leftover holes. The lambda sensor stays and I'm not sure which frequency valve your speaking of, but that probley stays the same too.
Sh!*can the cat, you will love the sound and it will spool faster and possibly better up top.

See this thread concerning air injection plugs.

CIS Air Injection Plugs - all are not created equally.

I have heard that removing the cat there are two options;


1. replace cat with straight pipe into original muffler.

2. Install new muffler that directly connects to the exhaust outlet of the turbo..

Is this correct... I suspect that a euro muffler would work.. what other muffler options???

Thanks for the info .....

Jwmarc: what was your successful method for removing the heat exchangers, all 12 nuts out ok?

You muffler choices are correct: cat bypass with stock unit or direct-to-turbo replacement Euro, B&B, GHL, Monty, Fabspeed, etc.

The removal of the nuts on the HE was tough... I left PB blaster on cotton balls stuck to the nuts for 3 days ( re-soaked 'em every day) before i decided to go for it... The barrel nut tool is definitely required and I purchased the 8mm long drive tool from our host. I was successful with 9 out of 12... 3 barrel nuts wound up backing out with the stud. Those I had to bench vise and work with Mapp gas torch to separate. Once separated I slotted the studs so I could use a flat blade screw driver to seat them in with locktite... I let them set up over night and re-installed new barrel nuts after lathering all parts with anti-seize....I feel comfortable that when I am ready to replace the HE with a new header set up I should be able to move pretty quick...

Hey rarly... thanks for the link ... while I respect John Walker I was concerned about his use of the 1/8 tapered plug... I do foresee a time when I will put everything back on the car... and I certainly dont want to damage the threads.

I got mine from Stephen. He said the seals that the injectors use will seal the plugs, new seals obviously.

$6 a bolt.... (oh yea, the copper sealing ring IS included though) And I thought the Weltmeister kit (which appears to use the same bolts/sealing rings as this one) was expensive @ ~$4 a bolt!

Do they have the Porsche crest on them somewhere??

Anything you buy from a tuner will have the P-Tax applied. They have a limitted buyer base and low production number products to sell.

You can get those bolts at a good auto parts store or a well stocked hardware store. They carry copper washers as well.

Man, I can't get the right washers anywhere here in my town, only from the main stealer...
The ones I got from IA didn't come with washers. I think you are supposed to use hollow crush rings, not actually plain copper washers ?
I'm hoping that when I get new rings from my stealer (same ones that seal the air injectors) that they are hollow rings. Anyone know for sure if they are ?
It might just be a language barrier between an Englishman and an American
