    E46 M3 Turbo questions

    Im currently building an E46 M3 RHD turbo

    Im building the manifold so that the turbo will mount where the aircon pump used to be.

    My question: Where can I run oil feed and return? and where can I run water feed and return?

    Man this is going to be tough to get an answer to.

    I only know of HPF doing RHD turbo kits. As far as people doing it themselves on a RHD, you are the only one I have heard of.

    same as lhd. If you're mounting the turbo that low, you'll need a scavenge pump. It's nice to have the pump sit low as well. But the water lines don't change at all, neither do oil lines, turbo is still on the exhaust side of the engine.

    What will the car be used for? Track, street, drag race?

    For track turbo cars you have to design everything for high flow and extreme, prolonged heat exposure. I've seen some pretty decent setups that fail miseably on track due to the nature of the long time under boost. Water flow is easily taken from the block drain (M14x1.5mm banjo bolt and fitting works well), and return to the inlet of the WP. On the S54, there is the suction pipe from the expansion tank to the back of the pump via a small 1" rubber hose to a metal pipe. This ensures a high flowing water circuit to prevent cooking the turbo and promote rapid cool-down after high boost runs. Oil can easily be taken from the back of the oil filter housing (M12x1.5) or get a filter housing cap that has 1/8NPT or M10x1.0 fittings. An AN-3 oil feed line is more than adequate, but you will need a scavenge pump if you mount the turbo that low as Bluejeansonfire mentioned (nice SNL reference, BTW).
