there are no bolt on let alone diagrams for turbo upgrades, those who have or are doing one, its all custom,
and bigger is not always better when it comes to turbos, size single/twin should be chosen from where you want the power to be available

and there is no main turbo they work at the same time, take off the factory bov, block the return pipe, and replace with your new bov

The turbos, I thought they work sequentially?

not unless you bought a subaru

2 td03's in parallel on the vr4

It kind of begs the question who suggested TD05s if they didn't understand the VR4? I'm not saying you don't want them, just wondering how you arrived at the conclusion.

A lot of people just assume...
If you actually look at the turbos it makes it obvious that they are not sequential!
