best bang for buck in a vp?

[VP_commo_driver]

ok, get my licence back in may, spending moneey on engine. basically what gives the most power for my money? im getting port/polished heads, stage 2 cam and chip planned so far.

leave it at that mate ... change your engine mounts, welsch plugs, gearbox mounts while your in there with the motor out .. save you $$$$$ and headaches later.

with those mods .. you'l lhave a better package than whats getting around in 95% of vn's vp's vr's

Good advice. And if you don't already have one, grab a second hand performance exhaust from the wreckers.

When your heads are being ported you may want to have the compression increased a tad.

well atm i have extractors, CAI to my pod, 3/4 of a sports exhaust. already have to replace engine mounts, power steering rack and tirods. what will raising the compression do?

 

[VN Commy]

Someone will be able to explain it better than me but raising the compression basiclly reduces the size of the combustion chamber (easiest way would be to have your heads shaved while they're off), causing the air fuel mixture to be squashed into a smaller area. This mixture is then denser and a property of this is that when it is ignited it gives off more power.

It would be best to talk to a cylinder head specialist on how far to go. The more you increase the compression ratio the more engine wear will occur. If it's just your daily you probably wouldn't want to go very far. It would also be best to run it on 98 to prevent detonation.

Get the heads shaved as much as possible (ask the head guy) it will really make you happy with the cam, if you put a big cam with stock compression you will loose power everywhere except on the very top end and even then you wont gain much. So porting and shaved heads first then cam (do cam at the same time though), then chip then exhaust. In order of power per dollar on the V6
