My girl has a 89 honda civic and she wants to get a new radiator, the old one is giving out. Is it possible to put an stock eg radiator in an ef since the motor is a 1.5 and eg's also come 1.5.

 

You should be fine really. If nothing bolts right up, you can just fabricate it to fit properly in the honda. I took a Summit racing radiator and hacked it to fit and fabricated it to fit in the engine bay. I am not gonna lie though, it ended up being a VERY tight fit.

 

One of the bottom mounting points lines up. You need to make an upper mounting plate and lean back the radiator a bit.
