Motors usually don't blow with age if they are well taken care of, motors only blow when they are mistreated.































Rev the engine up and see if you hear any knocking or noises, that's your best bet to see if the motor has seen better days. If it still sounds new then chances are that motor is still in top shape.

if your worried about having to change the engine quickly...i would choose the supra over the fc anyday...for one, the supra engine is easier to rebuild and with proper care it will last for a long time...while the fc and its fast aging motor will need to have lots of maintanance time and care...also rotory engines are a pain to deal with....

The 7MGE and 7MGTE have a reputation for head gasket failure, but it is easily rectified by torquing the cylinder head bolts down more. Wikipedia has more info about it.































As for the FC, it depends on how it is cared for. A properly maintained one will easily reach 200k with no issues. on www.rx7club.com, there is a thread about an engine that reached 400k. Plus, my grandpa's RX4 hit 375,000 miles just before he sold it. It really depends on how it's treated.
