Hoping my motor isnt weak
 

So I recently had my 2004 rx8 go down. Seemed like the starter wasnt engaging. Replaced that. Still not fixed. Figured maybe she was flooded. Got her unflooded. She started and drove a small distance and sputtered to a stop. Got her unflooded and got her home. Parked her. Got up the next day and tried again. Got her unflooded and got her running. Kept her running and monitored her ( this was the longest she had run since she went down without shutting off). Noticed she has a radiator leak. Shut her off then. My temp gauge is broken. So I'm wondering if her issue is just overheating cause of the radiator and then flooding. Or if my motor is bad. I haven't done a compression test yet (not confident enough to do it myself ). Any advice would be appreciated.

If its overheating to the point of shutting down, the engine is as good as dead.
Where exactly is it leaking and in what way is the gauge broken?

How old are the igntion coils? Can you pull the spark plugs to read them?

The plugs and coils are all new. The radiator is cracked and my temp needle is frozen. I got her running and shes dumping coolant into the exhaust so I know at this point shes fried. So what I need to know now is a good way to tow her without messing the up the body or suspension so that I can get her to a new home so I can start an ls1 conversion

A flatbed is best, I woildn't try other modes. Towimg with rear wheels on the ground is bad for the trans and towing with the front on the ground can end badly.

To be fair I'm not worried about the transmission cause I'll be replacing it anyway.

I had my car towed one with rear wheels on dollies. It's fine.

Just wanna check: you know the cost of an LS conversion, right? It's not really that cheap, definitely more expensive than just putting in a new Renesis.

I'm gonna be honest I bought this car specifically for this conversion. I just hoped I'd be able to make the renesis last longer. But to no avail lol.
