Very nice engines there!

Usually i re-build and tune many BMW engines.. i enjoy so much the 4 cylinders also (many don´t know the potential of BMW 4 cylinders engine even in naturally aspirated form)... even the old M10 surprise us when catch it up to current technology.

I made a full rebuilt in a S14 engine, stroked and rebored to ~2.5 liter (using Evo crankshaft).. it´s surprised me how strong is and the health to eat high rev.. 8.000rpm it´s only begin to play.. any rpm you release in rev limiter, it will eat and keeping the power curve usefull!

M42/M44 also are very health engines and small improvement in inlet manifold and camshafts, gives a big increase in the power output..

Your setup using 4AG throttle bodies appears to fit perfect!

What is it like to tune BMW engines? Just purchased an E46 323i(1998) and was contemplating fitting my M800 to it.
