10p dead, upgrade to 15p

HI to all. My Defender 90 TD5 has blown a cam rod and needs a new engine. I believe it is a 10p but thinking about upgrading to a 15p. Are there any other adjustments/alterations that i need to do please?

Hi, just saw this thread, you need the 15P with it's own ECU, add one wire and plug for the 4 pin airbox sensor and add one wire to the 3'rd track of the TPS if it's missing(this one might be there) also a 3 track TPS if it's the early one on the vehicle... and a nanocom or similar to make the ECU learn the security code
