Factory Rebuilt Motor
 

hey, ive found a car that i want to buy, its a 3rd gen RX-7 and its got a factory rebuilt motor in it with 20,000 miles on it. I have hurd all factory rebuilt motors have been rebuilt with used parts and they blow up after 25,000 miles. is this true? should i stay away?

"Factory Rebuilt" motors are not rebuilt by Mazda. They contract the work out to USA based shops about every 2-3 years. Therefore the quality can and does change over the years. A remanufactured engine will NOT use all new parts. It will use used parts which are within spec like any other rebuild. An engine which uses ALL new parts runs about $8000. Those can be had from Mazdatrix. The problem comes more into the QA that happens (or doesn't happen) with the remanufactured motors.

The warranty on them is a 12 month or 12,000 miles warranty (i.e whichever comes first). These motors don't last 200,000 miles anyway. If replacing a motor is an issue for you, this is not the car for you. At some point, these engines will give up the ghost whether its a Mazda remanufactured engine or an engine built by a specialty shop.

Sometimes, sometimes, they last 26,000 miles.

well i've found a 3rd gen rx7 i want to buy but it has a factory rebuilt motor in it for 20,000 miles. The last thing i want to do is buy it and have it blow up on me? Does anyone have experiance with these motors?

Yes, I do. Ran one for a few years. I only put about 25k (that was over about 4-5 years) on it before it blew, but that was because of other reasons. It had nothing to do with the motor itself. Had I not been beating the crap out of it at the track several times a year without the proper mods, it would still be running just fine today.

Ignore Rich. He was abused as a child. :D

The motors are as good as you treat them. Its not going to blow up as soon as you get it *if* the car is relatively stock; however its not going to last a 150k miles either.

Ha. Not abused, just feel like abusing people that don't know how to use the SEARCH function ;)

Mine made 26,500+ change......it must of been really well built. :rlaugh:

my reman lasted about 40k before losing a coolant seal. It was never overheated and was treated very well.
