getting a skunk2 pro manifold for my 98 GSR. I read around and do a little research to get a little bigger thottle body. the stock gsr uses 60mm i was thinking 65mm-68mm. i also have skunk2 tuner stage 1 cams i will be throwing in there at the same time. what kind of numbers you think i can put down with I/H/E, Skunk2 Tuner, and the Skunk2 mani? trying to hit 180-190whp

 

get a 70mm tb its really worth it
