It is a little bit hard then just making mounts. You have to put in a hydraulic clutch and on the KE20-25 you have to get a new sway bar made as the big ass sump on the 2tg will hit it. (this is where i got to with my conversion) Gearbox and tail shaft will bolt up if it is a manual car. With the mounts you can dodge the old ones to fit but the motor will not sit in the middle of the car, it would be easier just to cut some off a TA22 cross member and bolt it all to the motor and when it is in position just weld it up to the bare KE25 cross member.
