m40 tuning
Moderator: martauto
i was hoping it would just be a slot in job like it is on the m44.NoTurbo wrote:The long nose version fits the M42 with modification.
Can you get them both to your mates machine shop for a look?
It will be interesting to see a stroked 2.1L M40
the m42 and the m40 block are the same if im not mistaken. so it should work with some machining if i can be bothered with it
do you know what the modification the m42 needs
The M40 is actually quite good for turbo, my brother runs a turbo on his M40, it made 318whp and 413wnm. This on 2.5 bar of boost. He has blown one original head gasket because of knocking because his map was roughly put together.
You need to cut a 2nd keyway in the nose right behind the original one. Then you have to add another plug to hold on the timing gear. It requires a half moon cutter to the same spec as the original keyway. Usual cost is about £45 at a machine shop.ejoeyward wrote:
