OEM fans should have plenty of power to keep it cool. I did notice today that NA gen 3 fans have a massive dong out the back for some reason

Some factory turbo fans should work fine. They do on my koyo

Yeah gen 2 trims are all black, just grey roof liner

Defs needs a double din for carplay stuff one day

Didnt realise it was the wrong forum. Bugger it 

The tee for the heater core is most likely a "cylinder 4 cooling mod"

SUPPOSEDLY the coolant around the rear passenger cylinder gets stuck so the cylinder runs hotter. Hence the knock sensor being over it. That "mod" allows that coolant to drain into the heater core

OR

heater core bypass cos its fully/partially blocked

Most of the time the pump sock that comes with the aftermarket fuel pumps is rubbish and doesnt sit fully at the bottom of the tank which results in fuel surge earlier than it normally would. Best to use the OEM sock as brown as it is. 

A missing coolant temp sensor will cause a rough idle and hard start as the ECU assume its about to over heat at all times basically

With the right pump it should just plug into the oem harness. 

Otherwise id be buying a replacement plug and pin set and pinning the new plug onto the oem wiring. Biggest issue is insulating any joints you make. The fuel will eat most cheap wire/tape/heat shrink eventually

Plenty of stuff has happened

New job so dont have time/ability to write up forum posts at work anymore lol
