Something to consider is that your v4 bottom end is phase I and has a center thrust bearing. If you were going to use that block for a stroker, you would want to
A. use a phase I Ej22T or Ej251 crank, or
B. get someone like Cobb,Crawford or Axis to rebore the block for a phase II crank.

That said, if you want more displacement, I don't see any reason to use anything other than an Ej257 bottom end. It will be the most cost effective and reliable. If you want something unique and different, then go for the stroker set up. But you are going to spend $4000 on a block when a $1500 STi block will do the trick...

Oh, and of course, this puts you back into the engine management portion of things. You will need a PowerFC, or some other tunable EM to do this.

On the V4 heads, they flow really well. I don't have the hard numbers, but I can tell you the ports are huge. Heads will in no way be a limiting factor on this build. Getting the right turbo for what you want to achieve is the single most important piece of the whole puzzle...
