well, you can always mod an engine to make more power easy. But the trade off is always low end torque once you get serious. i know that cars in singapore are stupidly expensive as the tax or something is crazy. My bro moved there for work and he used to have a BMW M3 in the UK....now hes got a crappy Audi 1.6 A4! he hates it!!
whats the tunning industry like there, is it very professional or a bit lacking? this will give you your answer weather to bother or not!
you can get a few nice bits and peices, basically bolt on goodies, but for the money, it wont increse power by much at all.
gimie an idea on what your lookin for out of your car and i will try help as im in HK right now working for renault and am importing loads of tunning equipment....i can have a look at the 1.4 16V engine to see if i can spot any real restrictive part of it. ok?
