After much head scratching and thinking about the radiator situation I listened to Koro @sheepers and just got a radiator that fits. Using the telstar rad as a template as its the perfect size I went down a rabbit hole of radiator websites to look up dimensions, turns out the perfect fit while fitting the criteria of cooling a forced induction 2L engine is a EVO 1-3 unit but i wasnt going to drop $500 on a brand new one incase it wasnt going to fit so haggled a deal on marketplace for this Fenix unit with electric fan for $150, few bent fins to straighten and a rattle can overhaul but im not complaining for the price.
Yeah it just fits but I couple of quick mods will give me as much room as im going to get without hacking the whole front of the ute to bits. Water outlets will be easy to run with a few bends and straight sections but glad to have that headache sorted. Just the loom to sort out and mount an external fuel pump somewhere then il be close to firing it up
