ace0r-
my friend wrecked the yellow car...grrr
the red car does 0-60mph in 3.2seconds
so its not stock...the black car is my daily driver at run the 1/4 in a not to shabby 12.7@108 on street tires. it has 108,000 miles on it with stock motor/turbos
i dont know what year rx7 your brother has. but, if its a turbo, the first thing to modify is the downpipe. the basic stuff is usually an hour job for each item
ie. intake, exhaust and ast(air seperator tank)
the downpipe i'd take to mazda. they'll do it for 100-150 bucks. its a 2-3 hour job and i dont recommend it unless you have a lift or really good jack stands
email me or tell your brother to email me at
[email protected] if you want to mod the car.
