Phil, this turbo seems too small for the engine judging by how fast it spools up. just in neutral I could get 10lbs. of boost by revving it up, thats crazy. on my little dodge colt turbo, it doesnt reach full boost (19psi) until 5100RPM and in neutral theres no way I can get any boost just by revving it up, there is not even clost to enough load on the engine. I want to find out what bigger turbo is an upgrade for our engine, ie. would a starion turbo fit and upgrade??? I dont know
