The most interesting article about DISIs I've read in awhile...

There is some bullshit to sift through. There is A LOT of background to the thread. I know some of it, but certainly not all. I found the read to be extremely informative, and many topics are discussed. Read if bored.

Maybe we'll be seeing some 600-800whp DISIs in the near future...

If you mean the MZR DISI, I'd certainly believe it (but not in factory form, of course). Seeing that those crazy Puerto Rican dudes are able to push the 2.0 MZR to about 500hp without doing a whole ton of work to the internals, the MZR DISI certainly can be pushed further. It's a friggin awesome block, and very versatile too.
