It could be a number of things causing your problem. It's likely an ignition, fuel, or MAF problem. Weak or failing coils? Check your ignition coil harness for any damage or broken insulation. Did you replace the fuel filter when you swapped the motor? The fuel pump may also not be getting a constant 12v supply so try hard wiring it. I know you said you cleaned the MAF but RB25 MAFs are notoriously finicky! See if you can temporarily swap it with a known good MAF and see if the problem goes away.
Good luck! It would also be better to post this in the technical section under the RB sub section.
