i want to take an 87 Rx7 off my bros hands...it has a problem....it turns on and everything but after 20 mins or so it starts overheating.....what can i do about this? can i drive it like this? or do i need a rebuild? please help any advice will help! Thanks!

 

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.

 

Thanks! i apreciate the help to get me into the car of my dreams!

 

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....

 

is there anyway i can fix these problems....while i save up for a rebuild?

 

check you catalyst. fix the fan clutch or put an electric unit.

 

it doesnt have cat...and it has an electric fan too....whats next? do u think i can drive mean while?


Thanks Everyone!

 

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
