Yes you could use the Mx-5 SE short motor with the Astina BP-05 head. You need the FWD head as that IS where the thermistat housing lives.
The turbo engines have stronger pistons, rods and crank. The BP-26 head has a restrictor in the intake ports, some people at FL.com have substituted the BP-05 with positive results.
Oh yeah, good luck finding a well priced Mx-5 turbo engine :lol:


The pic above shows Rupwrechts engine during rebuild, you can see where the thermistat housing is located on the head.
