Hey everyone, So I am looking at selling my VZ SV6 Ute, and with that, and the money I have saved up I'll have a fair bit in the bank. So I am looking at getting a SV6 sedan either VZ or early VE and I have found a bunch of modifications that I need some more information about and whether or not they are even worth doing. First of all, if an Alloytec has been looked after, can they live past 250,000 KM pretty easily? Now for the mods: (If you can give your thoughts and opinions on them that would be great!) CPR6 Manifold/Cam Package = Heard good things about this, but it is very expensive. Cold Air Intake (Over The Radiator, or just the two hole mod) = Not to sure, the OTR is quite expensive with most brands. Air Intake Manifold Insulator = Don't have a clue what this does. Under Drive Pulley = Don't have a clue with this one either. Full Exhaust = Now I have found a few good bundles for this one, but I was also thinking get extractors remove that cats, and just have a full straight pipe from there. Now that would be cheaper and would sound amazing with the other mods but obviously be very loud, and illegal. Diff Gearing = Do not have much of and idea about this one either, with cost and where I would get it installed. Some sort of Tune = This is quite expensive, but would be needed with all the other modifications. Front Strut Brace = To stiffen up the ride a little bit. Brake Upgrade = Now not to sure about this one, but obviously it would be safer to have some better brakes. Maybe performance brake pads, and slotted rotors? I really don't know. Now would the engine/clutch survive this? And what about an auto, would the transmission be able to handle all of this? And I am assuming a if I got a Cross 6 I could do most of these modifications since it has the same engine? What sort of gains am I looking to get, and would a be able to get the estimate of a price? Is it even worth it, should I just get a track ready car like a 350Z or save up a bit more for a V8 as most SS owners would say haha! Sorry for the big read lads, but any help is greatly appreciated, if I go through with this build I'll make a thread! Cheers. P.S. I put a new engine in my ute, it was the 175 KW, now the 190 KW, and it keeps coming up with the error CHECK POWER-TRAIN, now I got the workshop to run a computer through it and it thinks that it is the Oxygen Sensor, has anyone else had this problem, and have they fixed it? P.S.S. How do you go about machining VE rims for a VZ?
