Here is an early drawing of a 3 stud engine I am working on.  This is what I thought Lego should have created for the Porshe GT3.

Larger size for bigger models. The piston is 2 studs diameter. The stroke is 2 studs.  New part allows for 90 degree cranks. works with existing engine block ends.  pins on top for creating cylinder heads.

If there is interest I may make available at shapeways.

May have to wait for brickshelf approval to see images.

thoughts or concerns.

Your engine would be too big for the Porsche.

Wait, Lego made a Porsche GTR? Where do I get one?

TLC should have come up with some new designs a long time ago. Now for the 42056 Porsche GT3 RS the scale of the 20+ year old piston engine seems to approach the real dimensions for the first time in history… If you mean by "3 studs" the width of each cylinder housing, it´s far too big even for 1/8 scale car models, IMO, I´d rather suggest – keep it by 2 studs.

Nice work anyway!
