with just n/a mods, it probably would just be a 2 whp difference with the lower im. I hadnt seen anyone say they noticed a difference with a ported lower imherbtea said:On the NGM site it says upper only 24 whp and then again on the combo it says 24 whp. Hmmmm
get the combo. or take your lower IM to a machine shop and have them port and polish it for you. it'll be a lot cheper than buying one from NGM and paying the core fee, or shipping your oem im back.sharky1 said:should i get the upper only or get the combo
Herb, I notice somthing when we put n your stage 4 Im. When we took of your stock, there was a little oil in it. Do you remember that? I don't think you Catch can is working properly. When I removed mine to install my headers mine was super cl;ean and my car is older than yours and have tice as much mileage. You might want to double check yours. Just lookin out bro.herbtea said:My brake booster line made it to the closest fitting, the pvc line I extended but I have a catch can so no biggie and the sensor one fit with just a bit longer hose. I had to plug one extra hole because the FPR line is routed differently on the 04 and up where as on the 03 it goes to the IM. (that one threw me off during install lol)
Oh yeah, I just got the stage IV upper and damn ........... I'm way happy with it!!!
Is the stage 4 install just as easy as that ? It seems that you're saying everything just bolts up,,,but then you have to add longer lines,,,,it that all ?If your talking about the stage 4 from TC, you have to buy new fuel injection hoses. About 2 ft of 5/16, 1/4, and I think 3/8? dont really remember the last one
