i think theres alot of misinformation on this subject. People should REALLY research before they post. First off the bmw m3 uses itbs and a maf and is one of the best N/A powerplants ever for its size. Skylines use itbs and i believe nissan pulsars which was a little mini skyline AWD and TURBO. ITBs on our cars WOULD NOT COST 6000. The hardest thing about putting itbs on a car not equipped is tuning. Tuning off a MAP signal is very hard because it becomes very erratic when the throttle is punched dropping very quickly and rising the same. Thats y almost all running itb setups use tps signals as a main reference. but if u incorporate a plenum into ur systems u can now run a maf sensor which until now i never really thought about(being a honda guy for many years) which should really help that problem since all factory itb cars seems to have been running them m3, skyline, pulsar. So, if u can have a plenum attached to ur itbs, tuning with a reflash will be very feasible and i believe drivablility very nice due to our air metering sytem. But u may not be very pleased with them without larger cams(stage 2 and up) since i always hear about itbs responding well to big cams. But they would DEFINATELY be a upgrade from our VERY restrictive intake setup stock. Im always down to talk about some itb setups(i have 2 in my grage right now) so lets keep this topic rolling.
