this is correct. fact is a single turbo 1.8t in either chassis, no matter the orientation, will have more room than the twin turbos, vr’s and v6’s. 1.8t parts are also infinitely cheaper and easier to get, especially when you start to consider the 12v/24v change over. I would say it is true of both performance and oem parts.
There are some great online place to buy parts at a more reasonably price than many dealers.
