The Eboost 2 looks bada** for sure. Very sleek setup.It looks like the pipes tuck up to the bottom of the kmember but make sure you have ground clearance for them.
I also have #80's and an HPX but I can't wait to get rid of the MAF once I get the Megasquirt up and running. The #80's will be fine especially since you'll be adding meth.
My car came with EMUSA Waste Gates and so far so good. Not sure of the blowoff valve tho.
I'm using an Eboost 2 for boost control. Too damn complicated for me but it works good.
