i have something for you....i put on an HP Racing Intake mani...i can get you one for like $300 w/ the fittings to hook it all up....it'll save you some time! Then you just get a short pipe w/ a filter or just a filter on the end of the tb.....top end is sick!! That coupled w/ a nice 4-1 header and exhaust would rip!!
Here are some pics of the one i have on my 99 GSR
If you're interested just shoot me a PM....i'll hook you up w/ the mani, the parts to hook it up and the directions to remove the old one and install the new one......
