Default 1999 miata dies when cluth pushed in - MS3

car is a 1999 with a reverent or likewise MS3 ecu

work i performed:
built motor with forged internals (machine shop did all but assembly)
car has a flyin miata stage 2 clutch kit
got the car running and idling and even driving well, however, everytime i start to push the clutch in, the car starts to stall out, even when im barely putting any pressure on the pressure plate.
ive gone through and tried adjusting rpm timing correction, etc. had to raise idle to 1500rpm to make it not stall with clutch

when the guy brought me his car it had stopped running and when i disassembled the motor the thrust bearing was heavily worn into the crank on one side. could this issue somehow be the clutch being too heavy? cant imagine it is due to the fact it starts to stall out befor i even have to put any effort into the pedal, but you never know.

had my son push the clutch while i watched for thrust play and saw none while he pushed it in. no noises or anything, just dies. afr is good throughout the whole stalling process

out of ideas and need some help
