    So here is my list of mods for my e30 325i: Thoughts appreciated on costs and options please ladies and gent. These prices are approx from various sources:

    Rebuild Engine @ £700 labour
    Schrick Cam @ £300
    Alpina Airflow header @ £700
    Stainless downpipes @ £400
    K&N induction kit @ £400

    Does this sound about right? I am currently sorely tempted to drop 6 cyl M engine in.....

    If it was mine, i would stick a 2.5 m50 24 valve engine in mate. Cheap as chips and a massive improvement over the old m20.
    IIRC they are not a massive job to fit in an E30

    Pending a compression test and a look at the pistons (I am thinking about posting some photos of these to get second opinions before I proceed with anything) I want to get another ~20 hp out of the engine.

    At the end of the day its a 138k daily driver (not high daily mileage) so my concerns are that I dont simply bolt a load of high stress ancillaries onto a tired/knackered lump. I would be delighted to get as little done as poss to get the increase I am after, the only reason I am looking into mods at this stage is that I am looking at a new head gasket & clutch in the next 1-2k miles and wanted to take the opportunity get it all done.

    The standard m20 is 170bhp and the 24valve is approx 195bhp.
    IMO that would be the cheapest way of gaining that power. You can pick up a tatty E36 325 for around 500 quid.

    Thats a VERY interesting point. I had considered a swap out at some length but couldn't reach a conclusion. What are the issues around transmission and loom etc?

    Ive got a feeling the engine and box bolt straight in, and you can splice the E30 loom into the E36 engine loom. Ill try and dig out some info at the weekend for you mate. Just PM me to remind me.
    Hopefully one of the other guys will read the thread and give you some more advice with this. A20 RYM is the guy on here regarding engine swaps.
    Hope this helps a bit mate

    The only prob is you might have issues regarding the EWS immobiliser system.
    The early E36 325s didnt have EWS so no immobiliser issues.
