Common VW turbo inlet/outlet sizes?

[Smokey Eddy]

What are the sizes (inlet and outlet) of the kkk 24, kkk 14 and a Garret T3?
Looking to order silicone couplers for said turbos.
thanks.

K24 is around 2.5IIRC The inside is small but the coupler will need to go over it all. IIRC what I bought it 2.5. The T3 should be the same. K14 I have  no idea. That is just for the air cleaner to turbo. The Exhaust to downpipe is around 2" or so. The boost pressure out let

GB will know I am sure

I know the outlet on a T3 is a bit smaller than 2", but I use a 2" coupler and seems to work fine.  I think the inlet is about the same.

KKK 24:
Inlet is 60 mm.
Outlet is 50 mm. (outside measurement)

So K24 is on the 49mm side of that, K14 on the 46mm side... is it better to run a 2" or 1 7/8" on the K14? How stiff are the silicone couplers?

[GEE-BEE]

Smaller is the turbo side, ( outlet) to the larger size  manifold inlet

They dont stretch as much as the epdm rubber..

i'm running a 2" coupler on my k14, secured with a t-bolt clamp, and it's been fine pushing 18 lbs

X2, make sure you run good quality t-bolt clamps, not cheap ebay kit ones, I snapped 3/4's of the ones my kit came with so I had to go buy some good quality ones.

I include 100% stainless steel lined clamps on all my products

The adjustment bolt is s/s also , all made in the USA and is aircraft quality

If you dont use a lined clamp , it will cut into the silicone....
