20b engine manual link? And compression?

I keep finding dead links for 20B engine manuals? Anyone got a working workshop manual link they can share please so save me posting a lot of questions!
One question I currently have is regarding compression. I presume the compression value is listed the same as for a 13b TT at 85psi? I ask because I have seen people saying they should be 110psi-130psi? Can someone please confirm.

Thank you
Lee

compression is linked to cranking rpm, https://www.rx7club.com/2nd-gen-arch.../#post12052728

the spec should be the same as the S5 13B, close enough anyways.

re the workshop manual, there is only the section F, the one for the emissions and fuel injection. the section for rebuilding the engine is not in the manual, and since it was only sold in Japan, its only in Japanese

I would have to check cranking speed on my microtech screen if I shows it? Rev counter is screwed and would not read accurate enough. So id the 13b manual os to go by and my cranking is in the ball park 90-92psi evenly across all rotors is pretty good?

+1 here! I have the Volume 2 of the service manual, along with the new model introduction book which has a breakdown of the engine with specs, but it's gonna be a LONG time before I can translate it. I'm still working on the wiring diagrams right now. For most things, just consult the FD FSM. The 20B is basically a FD engine plus one rotor with a FC style CAS & ignition system (1-2-3, then resets to 1)
