I bought a 1987 rx7 na for $400 with only 91k on it. Runs good but it overheats. I have changed the thermastat and rad cap. I will post pics later. Just going to need some help with overheating issues. I live in cny.

 

Welcome! That sounds like a good deal! Check the undertray, fan clutch, water pump, radiator, etc etc...

 

Yep and now i need to rebuild the whole motor.

 

dont assume you need a new engine until you rule out some basic stuff first! Does it drink coolant or simply overheat? Like funkjaw said check to make sure the undertray is still there (can you see the ground if you look under the hood?), as well a a GOOD condition radiator, clutch fan and fan shroud. There are inexpensive options to have the stock radiator repaired. Your key to determining if the engine coolant rings were damaged is wether or not your burning coolant. Open the rad cap on a COLD engine and look for bubbles when started... etc etc. 8 years of second gen exp now, lemme know how u make out

 

I took a video of it so i am almost 100% sure it is a coolant seal bad.

For $400 sounds like a steal. Worth putting to dollars in to fix the overheating for sure.

 

yeah, sounds like a good deal, good luck

 

sounds like you got a good deal on it man. ive been looking for a fc lately myself. good luck with fixing the over heating issue!

 

Nice deal. good luck with the fix.

 

Super deal right there! Hook me up lol

 

That price is unbeatable super conratz !

 

That's a steal!!!!

 

now thats a deal

 

that is a very good price in deed! i bought an 87 turbo 2 last year around this time for $700 all original everything was there on it motor was blown but i took care of that =) but u came uo bro

 

nice deal!

 

You got Yourself a good deal right there. lets just hope the overheating can be fixed without too much trouble. please put up some pics of the car and keep us informed on what happens to be the problem.

 

that's a great deal hope it only something cheap

 

too bad bro looks like a bad coolant seal> does coolant resovouir smell like fumes?

 

Dive right into that rebuild and post pics!

 

Just bought my 87 turbo II looking to sell it though as i know nothing about em!

 

Welcome, I own an 87 myself. Hope you get your problems sorted, if you haven't already. Fun little car.

 

Heres an option thats going to draw a controversy but its a viable one. Buy yourself the best copper stop leak you can afford. I use the bars bottle that doesnt require you to drain the coolant. Everybodys going to say it ruins your radiator and blocks up your coolant passages trust me it does NOT Ive used it twice and it saved me almost 2 years of no rebuild so far. Your at a point with that engine where it doesnt matter if it clogs anything, its either coming apart, or youll buy yourself a few years. You may want to add it with a spare radiator then switch to one you know is in good condition after. Say what you want...Ive had great luck with it with almost 400whp for 2 years now!

o yea, sorry for so many replies but thats definately a blown coolant 0-ring!!!

 

Sorry for the long absence been very busy and now the car sits. Cost to much to rebuild the motor and some stuff on the motor are going to need replacing. So now my question is there a Mazda 4 cylinder motor that will fit with out much modifications? Or i am going to sell the car for $400 to the first person with the cash on hand.
