I have an AE80 hatch that is well, showing signs of wear. It is blowing smoke and I think it is the valve stem seals and if it is not I'm going to change the motor, I'm not after performance I just want a newer motor I can get from a wreck rather than buy an old 4AGE have power I'm not going to use, having to upgrade the brakes and struts on the rear. I could have a motor lined up for 650 with 45,000 km on the clock, it's either 1.3 or 1.5 have to double check and I think it would suit what I am looking for quite nicely. The orientation looks the same. I'm wondering what the issues from changing the side of the exhaust to front and then running it under the car is going to be, and has anyone considered doing this. Any help will be greatly appreciated
