Hi any recommendations for the pipe sizes from the turbo to the intercooler and from the intecooler to the throttle body when using a FMIC.

Not using a kit as I am fitting a 94 wrx lump into something that isn't a Subaru, thus buying bends I couldn't use would be pointless

 

on my monster hybrid fmic that I had before I sold the car, I am sure the connecting silicone was 63mm (maybe 61mm)
Throttle body on mine used a reducer think that was either 73 - 68 or 71 -63

I may have an old hose so will check in the garage when I get in

 

Cheers

Last weekend I measured with verniers the OD (outside diameter) of the turbo outlet and it seems to be 48mm, and the OD of the throttle body seems to be 70mm. The intercooler in and out are 63mm OD.

Chances are I will try to run 63mm pipe from the intercooler to the throttle body but not so sure about the turbo to intercooler pipework.

It's going in a similar car with similar intercooler location to the one below but the intercooler has different inlet and outlet locations.

 

on mine the turbo I think used 51mm silicon on the turbo side, and then the pipework sort off flared out to the other diameter (possible 63mm)

 

Thanks again
