That picture came from here:
http://koti.mbnet.fi/trc/technic.htm And that engine made 564 rwhp.
I have done this
main cap mod to several VW diesels myself, since these tends to
crack main caps. This 1.6 turbodiesel made a little over 200whp, before it threw piston pin out :lol:
Just mill main caps flat and make steel bar on top.
