How much for the heater? Is it a straight swap?
Price id be looking for is £140 due to it coming with the custom items, Im not sure if it would be a direct swap but it can definitely be hooked up. I was going to use it in conjunction with my MPI engined unit, I think it can be swaped out fairly easily and will take up a hell of a lot less room than an original (think of all the activities you can do!!) and weigh a lot less than an original steel unit.
