question concerning coolant seals
my car 87 rx7 n/a
ok the coolant seals are blown in my car i originally wanted to put the internals from a parts car s5 engine i have into it but i dont really have any tools for workin on a rotary engine...so my question is being i have talk to the previous owner he says the engine was rebuilt around 15,000 miles ago...if i buy an engine gasket set can i just open the engine up an just go in an change the coolant seals an put it back together or are there going to be things i have to take apart that i need special tools to put it back together?

There's no reason you can't just do a soft-seal rebuilt (basic gasket set, plus front and rear seals)... unless overheating the engine damaged the block (ie, cracked the place where the coolant seals go, rusted the coolant passages or chrome plating, etc).
Ideally you might as well replace the hard seals (and port the engine while you're at it...it's not something worth pulling the engine to do if it's already running, though), as an extra 800 dollars will give you the much better long-term performance and reliability.
Make sure to buy the measuring tools (caliper, feeler gauges, dial indicator) and check that everything is in spec... replace what isn't.
