I would love to help you out but I am a factory technicians and I don't understand why you want to modify your engine. The factories spend millions of dollars in designing your car precisely, if you wanted a more high-performance vehicle you should have purchased the GTI, those are bad A$$, instead of spending additional money to make your Jetta into a GTI, my advice to you is sell your Jetta and buy yourself a GTI.
