RX1 engine teardown and transplant question

[SRXNOMO]

After a few years of sitting and selling off parts from my 2003 RX 1T, I have decided to pull down the remaining parts and scrap out the chassis. Before doing so I attempted to start, which it would not. I pulled the coils and plugs and did a compression test and compression was very low. This surprised me as the motor was running great prior to putting up in the garage. I had also put oil down the cylinders a few times and periodically, I would rotate the motor thinking I was doing the steps to keep everything operational and lubricated. This brings me to my question

I want to pull the motor down and check everything out to see why I have no/low compression, I am assuming stuck rings from sitting. Is there anyone that has a downloadable PDF version of the engine portion of the service manual? It would be much appreciated. I did a search and found a lot of detailed pictures and information, however I’d like to have the engine portion of the service manual on hand in case I run into any snags disassembling, measuring, and reassembling once I procure all the new parts.

Next question, would the engine run without the factory gauge cluster? The application I am using the motor for, I would rather not have the factory gauge cluster and simply use tachometer, coolant, boost, and fuel pressure gauges.

Thanks in advance for any help provided.
