RX7 rotary power, meth or water?

Just getting back on the site after being out of the loop for a while. In the past, I know you were a big advocate for pre compressor injection , but I cant see it on either of these cars. Of course there's every chance I haven't been able to pick it up in the pics and it is there. So just wondering if you've changed tack a bit with regards to the best injection points?
