need bolt on HP

I'm normally on the MR2 boards, but a friend of mine bought an 05 sentra with the 1.8L engine. She likes the milage, but laments the lack of power. I told her I could help with that. However, in my searching, I've found plenty of parts for the 2.0 and some for the 1.6, but not many for the 1.8 (that's the QG18DE correct ?) My question is where will I find parts for the 1.8, particularly reasonably priced power adders?
Thanks
Pete

Good luck with the 1.8. Try www.hotshot.com for a short-ram intake. 'Bout all I can think of. There are some links in the Sentra Readme sticky.
