Also, according to Mazda, the Japanese Rx7s had 207HP in 1991...but I believe it had to do w/ emissions or something....

Cone intake? Heck I added 10hp alone with my Rotary Engine sticker and some yellow electrical tape!

You'll have to switch the front cover and oil metering pump to the 87-88 style because on 89-91 cars the pump is computer controlled. On 87's it's mechanically controlled. You'll also need to use the 87-88 sensors.
I recently broke my 88 engine and had to buy a 89+ jpec because of the cost, availability and ease of swap.
So far I'm very happy with my s5 engine, it feel much stronger and smoother than my s4 engine. I didn't bother swapping out the turbo with the upgrade one i had. The turbo it came with had no shaft play. I didn't bother changing the front cover to go mechanical OMP. there was no oil leaks coming frm the front cover area so I better not play with it because is not broken and run premix.
