    No, M20 B25 has +2mm valves on both sides

    all regular eta engines have smaller valves. only 1988 super eta has bigger valves, just like the 325i. the difference is all valves are 2mm bigger for the 325i.

    Also,

    about halfway down the page i asked for some 524td parts and you said you had them, I emailed you and I haven't heard anything yet, let me know if still got the stuff i need. Thanks

    I'm thinking of building a stroker turbo engine too. What size stroker are you thinking about?
