For Sale: I have decided to sell my favorite stuff.... I have for sale now an awesome DBW Grimmspeed Intake Manifold, phynolic spacers, and matching TGV deletes. The grimmspeed parts are ported, Polished, and thermal coated, they were on my 06 WRX for a couple hundred miles before I returned it to stock for trade in. I also figure if you would want to go so far as replaceing the the TGVs and intake manny you may want larger injectors and an awsome Agency power fuel rail kit. The fuel rail kit has never been installed and the injectors are Helix 860cc top feeds. Your price.... $725.00 on MN Subaru, and you can keep your Intake manifold and TGVs, no need for a core credit with me.
Ohh, I also have 1150cc low impiedence top feeds with an injector driver, and dark blue 565cc top feeds from an 06 wrx< if those would fit your build better, the 1150cc would be more $$$ though....
if you are considering a topfeed conversion from side feed... I think you my need a fuel pressure regulator for a top feed system? I dont know if you even need that.
Here is the best full-on write-up/instructions that I have found. The top of the article highlights required components for top-feed conversion: http://www.iwsti.com/forums/how-install/234601-how-side-top-feed-conversion.html
