For those of you who have gone single turbo, what have you done with all those vacuum nipples(I don't know what else to call them)?

Someone responded previously that he had them all welded closed.

Is this the way to go?

Or is there some other way that's more convenient and easier?

 

Little rubber vac. caps you can find at any auto place.

 

Which nipples are you talking about?

 

Well there are at least 10 on the lower intake manifold and another 5 or so that are no longer needed when converting to a single turbo.

I have bought a set of rubber vacuum caps for them, but I thought that they may not be so reliable.

 

Those rubber caps are VERY unreliable. They shrink with the heat & will eventually crack & split.

 

If you get the silicone caps your good, but don't use the rubber ones. what I do is take a short piece of silicone and connect them together in sets of 2.. out of one and in to anouther, if you only have one left you can cut off a sort piece of silicone hose and shove a 10mm bolt in it and connect it to the nipple to effectivly cap it off. I do this on ones that can't be seen so I can keep everything looking pretty...

 

Thanks, this sounds like a good idea.

But does anyone know of a source for silicone caps?
Do they make them out of silicone?

 

They sell them here in Japan for like $4 ea for a 4mm then the get higher in colst as they get bigger.. So I use silicone hose...
