cheap or expensive parts dont matter it just feels good working on ur car and doing something different. there is nothing wrong with tuning ur car to keep a good performance. both fg's are great cars but if great speed is ur goal you got urself the wrong car. the k20 is faster than r18 but u can only go so far in speed with this cars. so whenever u top ur speed what do u do, get a faster car? swap engine? so why dont just get a lambo in the first place oh yeah can't afford it.

same thing as if u were saying why did u get the fg1 u should of bought an fg2 because is faster. (this is just a thought for the people making fun of small projects like this) anyways good job and good luck with ur car
