im gonna be using 2" piping from the turbo(DSM T25) to the intercooler(dsm 1g smic) and i was wondering what size connectors or transition hose i need to fit the turbo and intercooler inlet and outlet. will 2" connectors work on the intercooler and turbo or are they 1 3/4 or something, thanks.

 

measure the tubing on the intercooler and turbo, get connectors that fit accordingly. It all depends on what intercooler you have, and what turbo you have

 

yeh the size is around there
i dont think you will find a 1 3/4 reducer to a 2..i just can't recall seeing any
but if you get a 2" and clamp it tight it should be OK

if not got to AutoZone and get one on the metal ones used for the exhuast
put it onthe intercooler
and then you will have a 2" to 2" diameter

 

I had a 1 3/4 to 2.5 addapter made by turbonetics. If your willing to spend the cash they can supply you with one. But I say ---- that and clamp a 2" connector really tight. It will be fine.
