Heater issue

[Jezza_hr]

Thanks as ever for your input jondee.

Upon reflection, upgrading my radiator to a mishimoto may have had a negative effect on the heater, as the flow through it may have had a lot less resistance compared to the old one.

To put some more perspective on the water lines on my 20v, the back of the head looks like this:



and behind the water pump, these two points are actually connected.



My first thought was to put a T junction directly behind the water pump leading to the core, but that would only negate the use of the thermostat. The blanking plate on the exhaust side would only do the same. My only real option with this kit would be to move the T junction on the radiator pipe so it's closer to the thermostat housing, or am I just going to end up in the same position?
