Coolant inlet
So I dont have a heater core anymore, is there an option to get rid of the extra stuff (the piping that normally goes between the block and exhaust manifold)? Like a Kia water neck? Thanks!

50 Shades Of Silver (Na Eunos) | Mighty5s UK MX5 Forum I've always disliked the route Mazda used for the lower radiator hose (okey, I understand it was standardisation for aircon pump clearance). but as my car had aircon removed before I bought it theres no reason to have the hose close to the exhaust manifold when theres plenty of room to reroute away from heat... so, ebay and looking at other things I tripped over the shape of the Lower Radiator Hose Water Outlet Elbow for Mazda 323F. part number B6BF-15-161 , found a seller in Cyprus that has new items for £16 posted (possibly plus import? will find out [img class="smile" also, will UK Mazda dealers supplu for similar prices??? ) https://i.ebayimg.com/images/g/lksAA...iA/s-l1600.jpg basicly aims straight out of the waterpump & has the port to take the metal heaterpipe so no further modifications. next to look more into diferent radiators, thinking 90's Polo and an expansion-tank system and another consideration on Mazda's design of the '5 was the waterpump's coolant outlet to the radiator & heaterpipe as this sends the pipework near the exhaust manifold... I had intended to fabricate a replacement flange & pipe to aim foreward but I remember seeing a diferent shaped flange on the 323 cars (I used to work on & service a 323GTX rallycar) so ebay again and a new / old stock item was on the way from Cyprus Attachment 227808 Attachment 227809 Attachment 227810 as you can see theres a bit of a shape diference! also, the diameter of the 'stub' that the flexi-pipe fits is a few mm smaller on the 323 item with the heaterpipe connection in a slightly diferent place also theres no metal pipe-stub for the thermostat bypass (although these shouldn't be an issue for me as I'm re-designing the cooling system &fitting a 'twin-pass' crossflow radiator that hopefully will be more efficient than the Mazda design huge item ) waiting for the radiator to arrive now, then the fun of making it fit and plumbing with the added extra of deciding on shape & position of the 'expansion-tank' that's needed for this setup .................................................. . naturally, in nearly a year, I've done nothing about this but have done lots of other stuff... my intention is to do away with the smallbore (5/16" / 8mm) pipe that runs to the thremostat housing (no reroute) and turnt the 323 manifold so that the pipe outlet points down, the 'heater' port will be pointing foreward but thats then left as either an aux pipe run or can be blanked / plugged. hope this helps?

Totally does! It looks really easy to modify where the stock one...not so much. Thanks!

Super easy to weld if you know what you’re doing. You can flip it and run a much simpler lower radiator hose as well. Goes right through the PS belt, so if you happen to do this with PS, it’s a radiator drain to replace the belt. Gives SO much room for intercooler pipes and turbo manifolds.
