Looking to get a little more power out of my stock VT, nothing extreme but just some nice mods for a little more. I want to keep the car looking and sounding as stock as possible to avoid additional unwanted attention. So far people have suggested performance chip which I am looking into (with greenfoam) and also a slightly lumpier cam (crow cams 8531561 so minimal extra work is needed to accomidate. I am not to sure on the cam and how worthwhile it is so help there is appreciated I can live with a little extra noise as long as it isn't boomy or excessive, the quieter the better. Cheers
cold air intake - $0 to $300 depending on what u get panel filter - $100 or pod filter setup about the same 1.9 roller rockers - $700ish 81* thermostat - $20 if ur give it alot of stick oh and stickers +50kw
the factory holden supercharged one is pretty good and just bolts in also u can get from local holden dealer or wreaker but just get the ratio rockers they worth every penny ( pitty they cost so much more in nz ) and if u can by law just remove the back muffler and put in a st pipe it dosn't make it much louder and keeps in the cats as u need them in aussy ha ha
ours has a shaved head, bigger stainless valves , flow tested, bigger exhaust but same size mufflers to keep it down. chip redone and is getting a cold air intake when i get some money
