just a question guys will the scion tc headers fit the rav 4.2???
This could be because you said headerS, not header. There is only 1 header on most 4 cyl. engines. Once you get into 6 cyl and on, engines tend to have 2 headers.zoomie said:all i know is when i hopped into the dealership and I talked to one of the mechanics there, he gave me a weird look when i said headers. Does our car even have headers? i'm sure all cars do, but somehow ours is a quite different than the ones we're typically used to seeing.
beware of me. this is all coming from a guy who knows practically nothign about engines.
Well as an experienced old school hot rodder I would believe that they would function well togther (assuming everything fit). Exhaust mods are important to do in combo with engine mods to achieve maximum benefit. A critical determinant to optimizing the combo would be tweeking the RAV4 ECM to reflect the mods. As a newbe to RAVs I have no idea if dyno tuners have mastered reprograming of the RAV4's ECM.pyxy_567 said:i have no clue about upgrades in performance in engines but .... installing a header and the supercharger together is it OK or only one should be installed...????? ...SORRY , i feel like a moron right now for asking.... :?:
