Orphan

Lol I just realised that was my first post, i've had an account for a while and just lurked now and then. Tony I was in Canberra until the start of the year and have since moved up to Brisbane. Speaking of the 1UZ thats what powers my soarer Do you know Neil out at rush imports? He has a S13 with a 1UZ in it, last I heard he was putting on a 2.3L whipple supercharger and going to push boost down it until it broke. The VTC on the VH45 is controlled by two solenoids on the front of the intake cams, I'm not 100% up to date with how they opperate but I can dig up a pdf that explains how it works if you would like. It just runs off oil pressure so it might be tricky to get running without the ecu as when the revs go up so does the oil pressure meaning that less oil has to be let through to keep the same cam position. As it is just a solenoid it could be possible to have to run off a switch but then it would have to be manually activated and i'm not sure if the solenoid some how keeps the oil at a set pressure in the VTC system or if that was handled by the ECU. In short if your carbing a VH its not really worth the trouble to get the VTC working. Do you have a S30 Tony? I was planning on putting together a manual VH45 260z but after working out all the costs I think going with a VQ30DET would be a much better option as the engine is much lighter has a factory manual that will bolt up to it, sits behind the mid line on the strut towers and has a CR of 9.0:1 so upping the boost a little or using a bigger turbo is an easy option for a little more power. The engine is 270bhp standard in the older models and runs around 6-7psi from memory so with a front mount and exhaust you could probably get a good 300 at the crank which is more than enough to push a 260z around nicely. And when the 3.5L sounds like it does the 3L turbo should sound quite good as well and be the perfect little classic sports car, not to mention the VQ30DET has a stroke of 73.3mm and a bore of 93mm which makes it perfect to rev up to 7,500-8,000 with just new springs and retainers. Check out the video link below for a 240z with a VQ35DE.

You certainly can but you have to run a stand alone ignition system. There is a motorsport category over in New Zealand called superstock and there are quite a few VH's running and by the rules they have to be carbed and 4L or less. They sleeve them down to 4L new rods and pistsons + cams and springs dry sump carb intake and headers port polish and rev them to 8-9,000 and make 450-500ish hp out of them, not bad for a 4L.
