    i do see your point but its irrelevant on all but the last comment in terms of reliability though which is the issue here. as the thread is about upgrading to turbo power or converting to a yb engine and people are slating the yb i thought that the fact the yb will make 360 bhp for relative pennies was relavent although that may not seem clear in my previous post.!!

    325tds until i finish the skyline...........but i do quite like the tds!!!

    Not something the YB is particularly good at, i have seen numerous YB`s go wrong on every car site i have been on but never the M3 engine(including an m3 stage car). The YB was developed from the BDA, which was an incredible engine but the YB needs constant pampering to stay reliable. There is plenty of high mileage M3 engines that have only had the routine services but the YB cannot match that without a full rebuild. Personally i would take a silky smooth 6 cylinder purring away rather than a screaming 4 cylinder and im pretty sure most of this site would agree with me.

    take a 3.0 m3 to the equivalent bhp per liter (420) on stock internals, hammer it for 50k miles and see how you get on. in fact, just try to get it to 360 bhp and then consider how easily the yb achieves this with 1000cc less displacement.
    With a turbo the M3 engine will happily run on stock internals at 450 rwhp (500~ engine hp) for years....and thousands of miles. This has been proven over and over again in Eurpore and America

    The fact is they are far better built and engineered engines.
    Now dont get me wrong, the YB is a venerable old motor (and it is ...old....!!) but IMO its not in the same class as an M3 motor. Which run at 100hp/litre from the factory, naturally aspirated

    Theres alot of shit in this thread, its an engine at the end of the day. YB's are awesome engines IF looked after, just like any other 4 pot turbo engine.

    Several I know run over 400bhp and are totally reliable!! The thing about the YB is it comes in a saph, 3dr and a Escort, Saph being the cheapest and easiest to buy, and they get thrashed by people who don't know anything about looking after a car, There are alot of nails about, but there are also some lovely examples about, Like most performace cars.


    SCS,Reyland, and MAD engines running 600+bhp and get track abuse, day in day out are reliable, and thats still on a 20+ year old engine block/head.

    They are a great motor for sure.
    But for me a straight 6 will always win over on a 4 pot... its all down to the sound

    So you're telling me that they never have issues with their cars then?

    Totally reliable and never have a spanner put to it despite being thrashed on a track?

    I personally think that's BS but don't worry, I have a contact who is very close to the Reyland crew so I shall ask him to confirm this

    Reylands 700bhp Escort has had teething problems, but its never had issues on track.

    Look on passionford and have a search
