Hi Turboists

I tried searching many times for the answer but cant find anything, I need your help

The rubber intake connector from my intake pipe to the compressor housing has a hole in it.

I obviously need to replace it (I guess with a silicon connector) but I cant find the sizing anywhere.  I'm guessing its 4 inch on the housing down to 3.5 inch on the pipe (all stock piping on a BA).

Your knowledge will save me having to pull it all apart to check and may help fellow tuboists in the future

it's a 3inch outlet from the stock compressor housing

Thanks for the reply.  I am however, looking for the inlet size

I'm pretty sure that it's 3 inch all the way from the outlet of the airbox to the turbo compressor inlet. It might be bigger on that flex pipe between the airbox and the crossover... it's very easy to unclip it and measure it yourself, though, to be sure.

No worries.  Thanks

The compressor inlet is definitely bigger than the pipe as the current connector changes size (steps up)

I'm 100% sure that the compressor outlet is 3inch.

 

That "s-shaped" pipe fits inside two silicone joiner pieces which are obviously slightly larger than the pipe itself.

 

The "flex-pipe" between the crossover pipe and the airbox is the one you'll need to measure as I'm not 100% sure of the size there.
