New learning about the RX7
After letting it sit behind a shed for a decade, my dad finally agreed to let me get his 80 rx7 running again! Going to be my first time tearing down a rotary engine, lets see how this goes.

Can you turn the engine over by hand? If its free you may want to add some marvel mystery oil to the rotors and spin it to get some lube in there. A compression check is a good test to know if you need a rebuild. Normally, its the fuel system / carb that needs attention after sitting for prolonged periods.

My dad tried to get it running for 3 months before he let me look at it. My mechanic friend who is walking me through all of it said that the engine wont turn and I guess failed the compression test he did? The oil we took out also was more gas and unidentifiable sludge than just old oil. My dad also is okay with resto-modding, and I want to make it fuel injected, so we are doing a ground up rebuild at this point.

That's a beautiful Solar Gold 80 GS! That car has a lot of potential and I would no doubt restore it! Here's hoping you start a restoration thread on the car in the 1st Gen Builds section!! My 80 is the same color but it's the Leather Sport trim level!!

If the engine doesn't turn over, it's impossible to do any sort of compression test.....yes it looks like a teardown is in order. My concern would be the housings. A stuck motor could mean an apex seal has imbedded itself in the housing. They are NLA and difficult to find in good condition. Not impossible mind you, but they probably won't be cheap. You need to think about how far you want to fix it. Do you just want it running and back on the road or more of a total restoration?
Be aware, things like the door cards, dash and many other trim and interior parts are also hard to source. No aftermarket company currently makes any new replacement parts. Not to discourage you, just providing the hard facts of what you will face. I realize there is probably a sentimental attachment to the car. Your best bet in the long run, may be to try and find a donor car to source needed parts from.
