Cooler air means more power, right? People use intercoolers on turbo and supercharged cars to cool the air. Why not use one on a naturally aspirated car? Get a piece of 3" metal tubing 2ft. long ($9). Get some 5" pvc pipe 2ft. long ($10) and put around the metal pipe. Cap off the ends but only the area between the two pipes. Leave the metal pipe open so air can move through it. Drill a hole in the pcv pipe and fill it up with ice water. Make a plug for the hole so that it can be open/closed easily. Then just connect this to your air intake somehow. The metal pipe should conduct the hot/cold and cool the air flowing through the pipe.
After doing the throttle body bypass. Get a radiator reservoir tank ($5), some heater hose ($3), and a small electric water pump ($15.) Hook it all up where the pump will circulate ice water from the reservoir tank through the throttle body. This should cool incoming air and the entire intake.
Get 4 small pvc right elbows. Drill a hole big enough in the elbows so that you can slide them onto the fuel/transmission lines. Then slide some heater hose on and connect it to the elbow. Put another elbow on and connect it to the other end of the heater hose. Seal the holes in the elbows with something so it won't leak. Then run heater hose from the open ends on the elbows to a pump and reservoir tank filled with ice water. This should circulate cold water around the fuel/transmission lines cooling them.
Take off the exhaust pipe coming out of the passenger side of the muffler and plug the hole. Cut a hole into the bend of the pipe going into the muffler. Install removed exhaust pipe to this hole. Cut pipe and install a flat piece of sheet metal to each side. Using other pieces of sheet metal make plates with different size holes in them. Drill holes in corners of plates. Bolt plates together. You could even buy a Borla turbo muffler ($100) and install.
Take your current MAF and cut away everything but the sensor specifically. Get a bigger piece of pipe like some 4" pvc pipe and cut a hole big enough to mount the sensor into it. It might have trouble computing the quantity of larger air in the bigger pipe, but who knows unless they try.
Add a second MAF to your setup and have two air intakes running into your engine. Because the MAF measures airflow by using a resistor adn sending a specific value to the computer, there has to be some way to wire in another MAF sensor.
Get a bigger aftermarket MAF sensor made for another vehicle and have a custom computer chip burned that will enable you to use the different MAF sensor.
