20vt Intercooler inlet / outlet diameter

Im looking to buy a universal intercooler for my 20vt conversion. Can anybody help on the standard inlet/ outlet diameter, as I've seen many different sizes used for the conversions?

K03 & K03s turbo outlet is 50mm and throttle body is 63mm.

Cheers! Would I be best getting a 63mm outlet intercooler then, and having a step down section from the turbo?

Most people use this kit same one i used on mine fits nice just use the orig inter-cooler pipe and silicon bend from the turbo

Sound that is. Is there enough bends within this kit to make up the system. Because theres a number of different kits with different bends etc.

Yea you will have bends and silicon left over

Top man! Thanks alot
