There is a few different designs out there for re-location kits and i wanted to see if the original parts could be modified without buying a kit, so here is what i came up with

I fitted the engine and realised that it fits in the 86 with the heater and sensor block attached to the head if you remove the thermostat

So......

I wholesaw'd a piece of alu to make a blank for where the thermostat was and welded it up. Heater pipes were the next problem, one will work but has to be shortened to get a 90degree hose on it and clear the bulkhead. The other wont work so i welded it up


So i needed a return for the heater matrix so i used the original top rad hose position and welded a smaller tube into the original bolt on alu piece. Got some xtraflex samco hose to make a new heater hose


For the new top rad hose i used the original bullhorn head to water pump piece, cut it and turned it so that it now faces forward. I also welded in the rad fan sensor bung from the original thermostat housing bottom rad hose flange and this will switch the electric fan now as we have retained the 20v water pump system and havent needed to covert to ae86 water pump which i think is silly


So this is how the heater assembly now looks


This is how the bullhorn piece looks fitted and it clears the original 20v alternator in its original position. Now all thats left is fit a new top rad hose and a new bottom rad hose from the rear of the water pump with a couple of 90degree bends and an inline competition thermostat which will be drilled for water bypass during engine warm up
Whats with the red nut on the block and the blue rinse on the manifold ha ha
