Ok heres the deal my girlfriend and i both have 5gen civic dx,and we are getting a lot of money soon. So since i have two to mess with, do you guys think i should i go ahead and swap both out or just one and see what i can get out of one of the d15? This is just a thought or maybe i should do a swap and turbo at the same time on one and leave the other alone....choices choices....as of right now im leanin twords doin 2 swaps.The main question is:is the d15 really worth boosting. thanx
