Okay, first off I know very little about this stuff but just wanted to put a question out there for folks who actually know something about this stuff.

It is my understanding that twin turbo cars such as the 335i can have the 2 turbos set up in parallel like the 335i with both turbos spooling together reducing lag but sacrificing a little top end power, or sequesntially where the smaller primary turbo adds boost and prespools the larger one that kicks in at higher RPMs. It has also been stated that the 335i turbos are made of special material and attached to the manifold so it would be $$$ to replace them so would it be possible to add 2 more turbos so you would have a quad turbo with the benefits of both a parallel and a sequential set up at the same time? I'm guessing there wouldn't be room and I am sure there are technical reasons that would make it impractical or way to expensive but it is just a thought.

Concerning heat issues, would it be possible to add a larger Oil pan and 2-3 more quart capacity for not much extra $, and if so would this have a significant impact on engine temp or does the intercooler do most of the work so that the larger oil volume wouldn't have a significant impact?

Thanks
