Rebuild will depend on how badly it overheatd. Remove the radiator cap, start the engine and look for champane bubbles in the coolant. If present, rebuild, if not do a full cooling system check and repair.

how much would a rebuild cost me?

200 for a gasket kit, no hard parts and doing it all yourself, up to 4k+ for a decent race prepped motor.

since i dont know how to repair these engines i was wondering just a regular shop rebuild...just so it can get me to work so i can save up some dough to buy me a better engine.....

well i drove my bros car and i took notes on what it does...
-it vibrates under 1000 rpm
-Fan Clutch messed up
-popping noises when it starts
-minimal air bubbles in water
-after revving it above 1000 rpm,motor stops shaking or vibrating!
-doesnt accelerate fast..its does it slowly

can having faulty spark plugs or ignition system be the problem?

please help!

Coolant seal? I do agree with rebuild. Sooner or later...

rebuild...just do it

and the variable resistor is probably set to full rich...hence the vibration and popping @ idle....

You dont want to drive if its overheating friend that can equal death to the rotary not allways but i would not do it if i was you. The rest of the problems arent so bad but start saving for a rebuild you will need it some day lol .. welcome to the rotary world
