motor mount inserts will go a long ways on a MT car. With my auto I have no problems but they're definitely a good mod to have for you. AGP wga will definitely net you some good power up top just don't overdo it. Keep it under 18 spike and you'll be golden. Another thing I would recommend is plugs and wires...pushin more air up top makes the stock plugs unhappy. Plugs and wires can be had for about 55 bucks for both if you play your cards right (msd wires are 44.99 at modernperformance, ngk 4306s are cheap but reliable plugs).
