i have searched and the i am unclear on this, i am looking onto MSD 50lb, and I need a top feed rail. Will the MSD's fit into a GTI-R rail, yeah or nay.....I dont want to buy a 300 rail, i will just spend the extra for side feed 740's.....thanks

yes but you have to bore the rail out to 14mm or so, some people shave the injectors but i would never do that, gtir rails are way cheaper than msd injectors incase you mess up
