so far i have spent like 200 just on the ITBs. the manifold i had sittin around. and im gonna buy blocks of aluminum and CAD them to make stacks. then just gotta buy hose and get a custom TPS setup which i already know how to do. so i could probably spend less than 500 and have them done. then i have to get my car tuned which it needs badly anyways with all the stuff thats already on it. 200 for a tune. so less than 700. and lots of HP!!!
