Wouldn't you need a different manifold for that?

A little update and a possible problem. Installed the crank and can't do anything else for now as waiting for piston rings. I've done some reading online and found this: Wiseco Turbo 9:1 Pistons from Flyin'Miata for BP . It seems that i have the same and they don't work with a 99 head. Has anyone tried these pistons with a 99 head?

Installed 1 piston to see if it hits the valves. Rotated the crank without touching. I guess they will work.

Some progress. Almost ready to start. Turns out these pistons touch the valves at top dead center and the valves fully open. No contact with the cambelt installed.Not a non-interference engine any more but meh, hope it works.

Im glad the pistons are working for you. Are the FM Wisecos somehow shallower on the valve relief cuts than the off the shelf Wisecos?

More like the the diameter of the reliefs not big enough. Maybe doesn't have this problem with the bp05 head but as far as i know the valves are the same size so might still be the same.

Made some numbers. Running 20psi. Experiencing major heat soak issues. The red line was with the hood closed. So next up air box and ducting.
