Enhancing the performance isnt always about the motor. Suspension, electrics, shift kits for auto or short shifters for manuals.. heavy duty clutch, LSD... heaps of things play a part. Wat are you wanting? do u have an aim? and a budget? haha
First thing you need to fix is cut out at idle. there was a recent topic on that, try searching it. It could be many things. again need more details
But basically the first upgrades for performance are a cold air intake, a KN panel filter or POD filter depending on ur state laws and a full sports exhuast with extractors and y pipe. Depending on ur actual budget we can tell u a few more things you could do.. but they start to really cost the dollars.
Things like resetting the computer, cleaning the throttlebody and elbo and if its auto resetting the kick down cable are some free ways and usually make your car heaps better to drive. There are how to's for all of those in the how to section. |
Boost me, and double clutch me so i can get my. Loss of Traction! |

Going fast costs dollars. Usually lots and lots of dollars.
If I were you, the first thing I would do is get it as reliable as possible so fix all the little things wrong with it- and no doubt there's a lot of things wrong with it, just like most VNs.
Then I'd give it a really good clean and get it looking it's best. Spend some dollars on little cosmetic projects while you save up for performance mods. Not all of it has to cost much- polish your window trims and a few other parts under the bonnet.
In the past when I've had this discussion we've always ended up agreeing that the best bang for your buck performance mod is a new diff ratio- get some 3.7s or 3.9s and you'll scare a stock V8. |

they are all right above, but if u want some extra boost, a v8 t/b and a cold air intake straight into the air box will give you a bit more power if your not used to the vn already  there is sh1tloads more things you can do with out touchin the motor but u need to start some were. give us an idea of what your lookin to do and we can work from there! |

Most people don't actually want a fast car, they just want one that sounds tough as and goes a bit better than standard.
As Trizo says- what sort of thing interests you? |

| hey guys thanks yea im on a pretty limited budget at the moment and it sucks as i get only get my red p's soon which means any forced induction is outta the picture also because of the price.. the car only cuts out at idle every now an then sometimes it will run fine but then theres times when i'll be driving an come to a stop at traffic lights an she will die.. i was thinking of getting a pod filter an fitting extractors it has a 2.5 inch pipe on it which is how i brought it also i was wondering about a perfomance chip such as one out of a sv 3800 would this make a difference..? |

but ur not the only one man. but is annoying |
Take it sideways or take it home ;) |

It shouldn't be cutting out. Something is amiss but you could spend a fortune trying to track it down.
I'd go for the extractors and mate them up to the 2.5inch pipe- that's plenty of exhaust for a stock six. As for the pod, the better option- most people would agree- is a good panel filter and over the radiator cold air induction set up off a VS.
Performance chips are debatable as to whether it's worth the money or not. You don't need one with the mods you are planning but you might pick something up. Rather than go off ebay, I'd speak to Greenfoam at Justcommodores. Everyone who has one of his tunes raves about them and they are cheap. I'm thinking of picking on up for myself just to see what all the fuss is about. |

| yeah Id go the cai into the airbox with a pod or kn panel filter also a full servie can make a difference in power, as for you car cutting out sounds a bit like you have a busted manifold gasket! |

| About the easiest place to start would be your air intake and adding a cai. The cai seems to be a very oppinionated point, so with out any biased you have 2 options take out the paper filter that they cange3 every couple of thousand KM and throw it and get a decent aftermarket pannel filter IF you go for the OTR snorkel to the air box and change the standard air box top for the bigger one. If you decide to go for a pod filter then all this is not nessesary. Just do you research and make sure you do it properly. |

| your best bet for a cheap cai is ebay , around $70 from memory, as for extractors I have no idea what they would cost new, hunt around in the paper, they are fairly easy to fit your self just a bit of patience and a blok of beer will do it! |

Extractors vary in price depending on who makes them and the design of the extractors.
Pacemaker seem the most popular (I run Genie personally and had no dramas except they do hang quite low) and go for four into ones if you can. Cermamic coating is definately recommended or else they deteriorate relatively quickly. Plus it'll keep the under bonnet temps down.
Looking at my receipt mine cost me $800... but that was in Darwin. |
