its more for a protege. i rather spend a couple more hundred and get the hiboost or the mam turbo. they have been proven to work with the mp3. some turbo kit like that i wouldnt trust, just cuz its cheaper by a little bit.
check the for sale section there's about 3 different kits for sale...Cwill is selling his old set-up...which you can even search and find the video where he was kicking A$$ with it on his car.....There's being about 2 members that purchased that kit from turbo specialties and there's fitment issues and also the installation instructions is not MP3,MP5, protege specific..more like universal..lol
that is the TSI turbo kit and as i recall it requires some modification out of the box to work properly on our cars, or it is not totally complete or truly compatible with our car. go with MAM or hiboost.
Go for the MAM stripper kit and upgrade later. With the MP3, you should get some timing control or you'll detonate with the advanced timing. Or keep the boost low until you can get more.
