Hi guys and girls !

Does anyone of you know the dimensions of the 6 rubber sleeves between the air box and the intake runners on a 78 3.0L engine ? I plan to change into Samco Silicone hoses and need to know the corect dimension to order. I did a search but couldnt find anything. I need the inside diameter.

Thanks

V8 Man

Oh, thank you sir ! I`ll be waiting

Sorry , I chucked em , but i did measure the runner of my spare airbox ( 78 with the larger runner ) it was 45.3mm od. so that should give you some idea of what you need for size.
Personally unless you are doing something special i would not vary from OE.
They are cheap from sunset Porsche, they have spots for the clamps to sit , they are fuel resistant ( although not explosion resistant ) and thay are plyable enough to manouver when you are trying to put the " spider" back in place.

Good luck . i replaced my airbox fairly recently so if you have any more q's fire away ...

I have to run out to work ( yeah i know , that keeps geting in the way ) but i iwll lok again tonight because I am a pack rat and it is unusual for me to throw such a thing out.

V8 Man

Thank you so much for now !

The reason I plan on using non OEM parts is they are EXPENSIVE in Norway !

If I remember correctly they are 39mm. The early runners are larger than the later ones. BTW - I'm sure somebody here could buy the OEM ones here and US post them to you for big savings. Let me know, I can help you out.

V8 Man

Thank you so much butzip ! I`ll find out exactly what they cost in Norway and see what the savings are.

Thanks

No problem! happy to help.

I assume these are the same size for the 82sc 3.0L? I too am looking for a set. If someone could confirm this part: http://www.pelicanparts.com/cgi-bin/...911%20(1980-83)

V8 Man

4 bucks each ? I think that says it all Screw the Norwegian vendors

That should be the number for a US car, which is the smaller 39mm runners.

ROW cars have the bigger intakes, 928-110-158-01.

theiceman

okay slow down a little . The 78 and 79 US cars had the larger runner like i described. from 80 on on the SC they went to the smaller runner and smaller port on the airbox. I think the cars in Europe would have the same size.

genripper

Fairly confidant in my assesment as my 81 ROW Targa has the bigger runners.

In 81 the ROW cars went to the higher compression engines, 930/10, and also confirmed that number on the PET for ROW cars in 81-83.

FWIW.

Sorry i need to clarify .. what I meant was 78-79 ROW an US are the same runner and boot size,and as pointed out very cheap.
