if you gonna run boost, vtec is hard to make reliable power with. it takes 2 sets of MAP readings, 2 sets of tuning. its just easier to run it withiout it. my friend ran into all those problems with his D17A2 with the T25 setup. we basically disabled Vtec. set it so high that it never engaged. over redline with the turbo on there. for a B18, T3/T4 doesn't spool till way late. go get a GT25 or a t25. gt25 is better of course, will be more reliable. superchagers are for rednecks though, and the S2K. autocross cars, and straightline. downside to supercharging is gas mileage. and mustang guys will tell you all up and down they get "GREAT" gas mileage with their Jackson supercharger... they might be lucky to get like 20mpg. turbo can be driven easily and under boost. of course, without the boost, theres no power, but the gas mileage...its AWESOME. my friends D17A2 with the T25 setup, he drove that to about 2k-2.5k rpms, without the boost for the gas mileage, it got liek 40mpg. no shitting. on boost the fuel gage just kinda took a nosedive though. but it kept with the mustangs, at 170whp... does that say anything to you? mustangs aren't all that fast anyways. now....bikes are another matter. those things are geared to do like 75 in 1st gear... if you wanna go the fast route, go buy yourself a bike. 1000cc. turbo setups can be done to be extremely fast, but the bikes come that way... or if you wanna embarass some dickhead, buy a shifter kart. like 400cc motorcycle motor, or 600cc motorcycle motor.....go get the 160mph mark on the interstate.
