Aussieyobbo16 7 Posted June 20, 2020 Looking to put a healthier low ks motor into the xg. Can I use any sohc motor with relative ease or is there a lot of difference in wiring and ecu. Likely looking at ef/el but possibly also au. Or would be better with just xg of eb/Ed Share this post Link to post Share on other sites
SPArKy_Dave 8,873 Posted June 20, 2020 Have you done a compression check on your current engine? Failing sensors, injectors etc, can also cause a loss in power. Share this post Link to post Share on other sites

deankxf 20,288 Posted June 20, 2020 if you want to read a LOT... but learn a LOT.. this thread below is all you'll need probably. if you ask Me, the AU is too hard into XG due to the alloy sump.. (mate of mine did it, paid $400 for a TUFF MOUNTS Barra conversion sway bar..) then you still have to do the same mods as for EF/EF which is either use the serpentine belt setup or convert it to the V belts (EF onwards water pump outlet is smaller, so you need a custom joint in your radiator hose for that.. if you get an EB or ED (or even EA if they still exist.. 3.9, 3.9 was also in series 1 EB, which My brother thrashed the shit out of one to 400,000km and never had any issues other than a head gasket and dissy worn) if you do a compression test, and it's fine.. i'd consider not changing it.. unless it has worn bearings and other problems. depends on the budget also..
