im trying to build a rx into a track car. im possibly going to swap out the turbo for a wrx unit, but what i need to know is, are there any other mass air sensors that will be a larger diameter but still compatible with the rx, ill most likely be installing a larger throttle body and an intercooler along with the new turbo. i know that the cars run like crap without the sensor, but the stock one is too narrowand it wont allow the use of an aftermarket cone style air filter. any suggestions or advice?
