Hey guys im looking into buying a turbo rx-7, needs lots of work but i havent own an rx-7 since 2007, what are the bad spots to check before buying ?

car has emission block off plates and idles a bit rough.

does the ecu reset and make it run weird on idle if the battery is completly dead for a long time ?

i dont know how to post pics since imageshack.us isnt working like bofore

If the emissions have been blocked off, then it is unsurprising it idles roughly. "Emissions" can mean many things to many people and sometimes includes non-emission components like the BAC valve. Who knows how the car has been hacked up...

No.

At the bottom of the reply, you will see a button "Manage Attachments". Click that then you can upload attachments. Probably need to resize them to around 250K before you upload them as most picture are several MB right from the camera.

 

check the back story on the car. how many miles/etc. why does he say it's running rough? what fuel/ecu setup does he have? car still have CEL if it's USDM?(guessing not since saw you're in canada) try to pull codes if possible. I know removed emissions would come up, but curious what else pops up. Like ECU not seeing an injector

Would be nice if you can take off intake pipe leading to turbo and pipe after turbo and check for oil to see if turbo is leaking oil into intake track. taking off intake pipe leading to turbo would just make sure it's not a ripped pcv valve leaking oil before the turbo.

Compression test it if he lets you, or at least crank with spark plugs out, or at least drive the thing and make sure it's fine in boost.

Check for smoke upon cold start. I always like buying cars that people haven't cleaned anything before I show up and I always like cold starting them to check for possible bad coolant temperature sensors, or seals going bad.
