At the moment I have a standard T3 turbo and standard original air filter box linked by a hose of 60mm inside diameter. In the future i will upgrade to a T34 turbo (but only once my T3 is totally knackered) will the 60mm hose that I have be suitable for a T34 or will I require a bigger inside diameter hose?
The reason I ask is that I want to buy a cone filter to use on my T3 but I don't want to find out that the neck of it will be too small if I have to fit a larger hose when I eventually get a T34, if that's the case I will just stick with the original air box until I get the T34.
