I wouldn't be on your spec, as I would be sensible enough not to dig my heals in about certain aspects of the spec. Cams are cheap enough to change / reprofile, so I would speak to ONE person who I had decided I would take advice from (Mark is talking to you at present , so LISTEN to him ) and see what they thought.

My final advice would be to NOT chase numbers, and go for driveability. This WILL mean cam changes AND lowering the c/r to achieve the figure you want and make the car drive nicely.

I love the way my car drives (and would NEVER go back to the likes of my Sapphire), so I would suggest a GT30 and some short duration cams to get it on boost ASAP. This will mean the car will not be as exciting to drive as your last conversion, but will mean you will probably get more from it.
