I built a a2w system on my lgt a few years back.. I used frozenboost's type 16 core. I was tired of blowing end tanks so since I had all the parts lying about I fabbed it up. Transient boost felt like a buddys ported td04 with a mbc with my vf52. It was instant.
I picked up a good bit on the top end by holding boost longer. And being able to lean the afr's to right around 11.9 and added 3 degrees of timing. I was seeing about 3.6grev mid range at 19psi.

Now a friend of mine has bought most of my parts. He has a perrin top mount right now but in a month or so we will be swapping my a2w setup on to his car. So that will be a cool comparison between the perrin vs the type 16.
