No, I did not put pvc piping on it.....if you didnt read i have mabe driven the car 5 times max. Im trying to get a stock B.O.V. so i can make it recirculating because I cant stand when it boggs. I did not put that coolant hose on there either. Those will be going soon enough. I SAID I got these headers because the stock ones on there cracked really bad. I WOULD CALL THAT MAINTENANCE. But look at is as you please. 750cc injectors will be on there BUT I know im in need of a fuel pressure regulator. I was told not to run a Evo III 16g on stock fuel pump and injectors, so I have not beaten on the car. I got the fuel pump in today.
