Basic maintenance. Don't even start until you've checked all the vacuum lines, coolant hoses, and everything else that is going to head south on you the instant you try to add performance to a 15 year old car.

also i don't think i would list the FPR as optional the whole way thru, i've heard plenty of stories about walbro's 'blowing apart' the stock regulator :0

my 2 cents, good to have a guide line though
