i dont think a complete tear down manual exists (may be wrong). there is information avaliable on different sections engine, brakes, suspension, transmission but no one stop shop. scoobynet is good for technical stuff i find.
we could be more usefull when it comes to a specific task.
what information are you looking for first. are you making rolling chassis first?
also is car going to be standard and are you fitting original phase engine etc into it. you could end up with a bit of a diy job on wiring loom if trying to mix and match ecu, loom and engine.
