I was there with my son, i had the white AW11. Told you that i could hear the big ends going.
I do have the loome and computer it is still attached to the 4AGZE that i removed from my car after blowing the gearbox. May be an option for you as it is setup to bolt up to a C52 gearbox that you have. It is complete with supercharger. Motor is in good condition never had a problem with it.
