is it worth my time swapping a d15b7 to d16y4

It's an obd2 motor, non-vtec, rated at 120HP. So that's 18 HP more than a D15b7. Not worth swapping an entire motor for 18 HP IMO.

I'm not worried about the performance I'm not modifying it just seeing if it worth buying a new motor instead of fixing the head gasket on the current motor

Thanks for the advice I'm going to replace the head gasket found out why it went so quick ends up that it was the distributor shaft that has caused the head gasket to give way
