will a 1.8 intake pipe fit onto a 1.6 throttle body and all those hoses that it needs to get hooked up to? im wanting to run a larger diamater intake pipe over the top of my anti-freeze hose. then im going to run it to the Rx-7 AFM then to my diy TSI. i figure since the RX-7 afm has a 3" outlet then it should have a bigger pipe to run to the throttle body. now my original idea called for pvc, but when i saw those hoses connecting to the intake hose before the throttle body it made my plan much more complicated. so im trying to find a way to make it happen. any ideas?
