Omega General Help / Re: poor headlight beam
« on: 06 December 2008, 16:03:23 »
before u do any light swaping try checking the voltage at the plug that feeds the bulbs, for whatever reason the voltage drops on a lot on cars with age, i know you might think it sounds daft but ive come accross loads, mk2 astra used to be tw!"s for it., they often had only 6 or 7 volts at the plug, you can usually just add a lenth of wire from the high low beam switch or fit a relay like u would on spotlights

if u are gona do the v6 i just had a thoght, if use 3.0 heads they might lower the compresion enuff because they probably have a bigger combustion chamber than the 2.5 heads and that way you wont need to mess with spacer plates and you will also get extra power from the 3.0 cams, thats assumeing the 3.0 heads will fit a 2.5 and assuming the combustion chambers are bigger wich they will be unless they have used the pistons to make them bigger, you should ask somebody on the forum that knows more about the v6 heads as i've never looked at them, if they can work you will save lots of time and money and do away with unreliable spacer plates

wow, you must really want some work to do, ive dun a few turbo conversions on non turbo stuff like, astra gte 2.0l 8v, astra 1.7d, astra gte 16v,xr3i, and a 2.0l zetec bottom end into rs turbo with standard 1.6 cvh rs turbo head and 2 transit 2.5d, the transit was the only on that was worth doing as oposed to getin the proper turbo engine
(thats only because those engines are upto taking the heat and boost with no mods) the pistons in no turbo petrol engines are cast were as turbo pistons are forged so non turb pstons will end up with holes in due to all the extra heat, if you only run 6psi they may take it but 6 psi with the lower compresion ratio will hardly be worth the bother, but if u do go thru wth it spacer plates can work if there made and fited corectly but they will alter cam timing slightly wich will reduce power, also the crank bearing shells in turbo engines are tougher so u will need to change them but u will have the sump off anyway to fit the oil drain 4 turbo , u will also need a oil feed to the turbo( oil cooler pipes are a good place for that, if u really want a turbo omega a c20let from calibre really wud be your cheapest and best bet, it might be 500 cc smaller but it will be loads lighter and so will inprove handling and all sorts

i wouldnt dream off changing the pump, i just wonderd if it was an easy job, but it isnt so i will just fit an old style relay set up that just puts the plugs on for 10 seconds everytime ignition is turned on, i know all to well how dear pumps are, i havent got enuff fingers to keep count of the people that came to me with dti ecotec vectras that i had to give the bad news to when i was still in the trade! vx are well out of order for those dti pumps they should of recalled them

« on: 15 November 2008, 17:29:17 »
not sure on the omega as it was ony vectra 2.2 and 2.0 but not to bad at all as i remeber, just a basic turbo change really oil feed and return off then down pipe and boost pipes, then all the manifold nuts, the car shud still start and tick over with sum fresh oil in, they tend to start to suck oil again if u rev them over 2 grand, if it does just make sure youve got it in 3rd or 4th with ya foot on the brake and just stall it, also some times all the oil goin thru exhaust knackers the cat so u should budget for a cat to be on safe side
