I have a 1997 Honda Civic Dx hatchback, Can I use the stock radiator with a GSR (b18c1) swap? Does the radiator need to be from a manual car (ex,cx, lx or dx)

I know Del sol Rad. is the best suggestion just need something to get me by.

 

Have seen it done/ used a Civic single core myself on a b1 swap. Your stock radiator is ok, less than ideal but will work. Does not matter if it is from an auto or manual car.

 

Yes, you can use your stock radiator. The engine will run a little bit warmer, but it'll still be perfectly safe.
