Hey, my biggest worries are doin engine modifications for my 2.0 jetta, then down the line experiencing problems, however are there any side effects to replacing my cam, and adding an ecu chip for 2.0?, not lookin to race, just a lil extra kick
Gas mileage will go down. thats the only real issue. It will eventually wear seals and stuff down faster because of the higher output, but it might be liek 10-20K off the end. so 120K miles untill the seals burn rather than 140K? I dunno but that would be a hypothetical.
A cam with with a higher degree, anything above 256 for a 2.0L, will give you a little rougher of an idle, nothing big though. If you go above 270 degree you will most likely feel a loss in low end torque too.
