That website was just what google found for 2jzgte.

Im interested to see figures from other flow bench for M103 and 104 heads. If possible could you write them here in this topic?

My flow bench figures is tested in 10" of water, and that 28" field is actually calculated by program, so... lets not belive its absolute right.

Oh.. and i didnt say supra head is good, but in some videos it sounds just nice whith big turbo.

It's also quite a bit heavier than the M104... It does sound sweet though. But the shorter stroke M104's should be able to rev higher...

Comparing Toyota and Merc Iv been thinking about same thing. Keeping the stroke 80.25 and still having 3 litre 24v turbo . M 104 also have little bit bigger valves...

It also has a larger bore spacing, IIRC a larger coolant area in the block, a chain driven set of cams, bigger head bolts, and a better rod/stroke ratio...
