I am a proud new owner of a 54k S50B32 and I would like to know what the valve lash specs are. Also what weight oil do you guys reccomend?

Thanks in advance,

Ed

Just curious, is this engine going in your M coupe? I also believe a 40 weight is pretty commonly used in the S50B32 but others will chime in.

Yep. The engine should be bolted in and running by the weekend. Just working on cleaning up the valve cover and aluminium intake manifold. Also doing a valve adjustment.

For the valve adjustments I used 0.18"-0.23" on the intake and 0.28"-0.33" on the exhaust side. As for oil I am currently using Amsoil 5W40 oil and I am very happy with it.

Congrats! I wouldn't mind looking into that swap...however in CA it is rather illegal (OBDII to OBDI). Would have to pay someone off lol.

I have a year and a half to figure out what to do with emissions inspection....

may i ask what kind of engine was original in your ride?
I thought all M coupe and M roadster are with s50b32 pumping out 321 hp!!!
Sorry, I am not in the US, you guys might be getting something else.
I had driven my friend's m coupe here in hk...man, that car was a beast, damn fast

In the US for `98 M roadsters and `99-`00 M coupes we got the lame duck US E36 M3 engine which was not a true Motorsport engine but simply a stronger M52. It was 3.2 liters with 240hp...nice mid-range but top end was boring. Luckily the `01-`02 MZ3's here got the S54 engine :)
