I've been browsing this forum and other web sites looking at mod'ing my '03 R25. [It's a 1.6 injected auto with I believe a 52 mm throttle body as st'd]
I've already done the 'dirty airbox' mod'.
I'm going to put new piper cams in [ARKBP270H ]
and a full janspeed exhaust system [ with sport cat].
Some questions: Are vernier pulleys essential?
Do I need to upgrade the valve springs?
comments on a replacement ECU? reprogrammable?
Induction stuff - I'm undecided here.
Lots of info' on what induction kits will do - perhaps but at quite a cost!
Looking at one of these: Pipercross Viper, BMC CDA, ITG Maxogen - all expensive.
I want performance, better fuel usage and little noise.
I have read an article about using a K&N panel filter and carefully rerouting the cold air feed [bigger bore -less kinks] for a power gain proven on a r'road
Comments and advice on these points would be welcome.
Ta very much, HTR
