I have seen 1 of these for sale here in OZ for offers over $1000 (400 pounds) it does not have the fuel rails or the throttle body, is it still worth the money? Also what else would i need to get to put it on a big turbo escort cosworth. in the future i would like to upgrade the power on the engine should i get it in preperation? or is the money better saved and used on other engine parts? Eventually i would like over 500 bhp from the engine.
