    have a 97 p 323 coupe
    what are the parts required for turbo conversion
    i know the obvious, but are any engine parts needed ie: rebuild or is the standard engine up to the job?

    what about remap for the ecu?

    Thanx

    Alright Gav,

    I've not done the conversion but had a few turbo charged cars and built a 400hp nissan. In terms of whether or not your engine is up for the job it all depends on what power your looking for ?

    I'd imagine the engine would be good for between 350-400hp before you need to start changing con-rods and cylinder lining's etc.

    However you will need to change from the head up. firstly I would be looking at trying to source a low compression stainless steel head gasket. you will need a turbo exhaust manifold, the turbo, turbo-exhaust downpipe, a silicone adapter pipe for the air flow meter to turbo, a dump valve would be helpful.

    I think your main problem is how you are going to cool and lubricate the turbo charger. You will need an oil line in and out of the turbo and also a coolant line in and out, not sure if there is adapters for doing this ?

    Finally, I would be guessing you will need an ECU that can be fully mapped. The labour is that hard but it will be costly and time consuming. I would guess you'd be better off sticking an M3 Evo engine in there !

    hope this helps,

    G.
    You have to give me credit for trying !

    You would need

    Thicker head gasket to lower compression ratio (the US ones fit)

    ARp head studs, stock ones are sh*t and lift under boost

    Turbo

    Oil feed hose

    Tap the sump pan as a return oil feed

    Exhaust manifold

    Downpipe

    Intercooler and all pipework

    Custom remapped ecu by someone who know what they are doing, Active Autowerke in america offer a 'remote' service I think

    or technique tuning

    Wideband sensor and gauge

    Boost gauge

    and lots of other bits I forgot

    you will need wastegate, blow off, boost control, maybe bigger injectors, fuel pump and regulator. oil temp press gauges. it never finishes, but it is a lot of fun.

    manifold and turbo is certainly crap in this kit. turboing a car is not a cheap toy. you must buy good and reliable parts for your happy future.

    i would suggest you put an M3 EVO engine in it for better performance and more power and less trouble in the future! Turbo conversions are not very reliable from what i have heard!
    My BMW history= E36 318IS, 323I,Mini Cooper, E46 320 D SE and now E39 530D. awesome

    Are you sure that US head gaskets are the same with euro ones. Can I use usa cometic mls in my euro 328i ? Also where can I find arp head studs for my aliminium block 328i ? I didn't see it in any website. Websites has for iron ones.

    why don't you just supercharge it? bolt on kits, that produce 8psi and 80bhp. no need to change the internals either as these cars perform well with superchargers!
    there is a reason why there are lots of companys selling chargers, and not many at all that turbo them!
