Jarret,
I will try to get some better photos of both housings.............I have several I took
while doing the small amount of machine work (milling machine) to adapt the Mistral
back-plate to my 13B front hsg but they may not be detailed enough for your needs
and a good rear view of the Mistral 13B with water-pump and alternator.........I have
determined that the Renesis front hsg appears to be a direct bolt on to the 93-99
13BREW and the Japanese Cosmo 13B and 20B with only 2 existing machined pads
that have to be drilled and threaded for 8mm studs............The main possible conflict
that I have eyeballed may be if the left side of the Renesis water-pump comes too
close to the top left (from the cockpit) mount ear or the mount itself......That possible
problem might be surmounted by adjusting the pump position slightly with computer
magic..........The problem with moving the pump position using the Renesis pump is
the studs do not move and might end up in the middle of the pump.............If that is
the case a pump closer to the size and shape of the Mistral pump would need to be
sourced............This conversion would need to use the Renesis frt hub, pulley and
timing wheel plus the ignition pickup sensor................The Renesis frt hsg will bolt to
the 86-91 13B but lacks the afore mentioned machined bolt pads and would lose an
important stud next to the top left mount ear and one further down the hsg that is not
as critical for structural integrity.............Will send what photos I have in another post
as I am not on my home computer...........
Best Regards,
