Can I possibly port and polish the MEVI to allow more airflow or is that simply impossible?!

 

What you'd probably benefit from is port matching your heads and intake together. I'm working on a set of heads and noticed that the intake runners don't exactly match up to the heads, there's definately some power to be had there - may not be a whole lot though.

I do know that you can port the heads, as stated above, I've been working on a set in my spare time.

Once they're done, I'm going to take a trip to EIP Tuning or TurboXS and see what the dyno says
