Default 1uzfe vvti cooling issue

looking for some help, info and suggestions.
last weekend i had my track car out that i done the 1uzfe vvti conversion on and had an engine failure
so im looking to know is there anything i can do on the cooling of the vvti version engine to allow coolant flow more easily around the engine?
basically the engine started to put up pressure in the coolant system.
for cooling i have a large capacity koyo alloy rad fitted with 2 spal racing fans, so cooling should be more than enough.
the issue i think is that the coolant system is pushing water out of the engine and out the overflow of the header tank.

if you cant get a larger radiator, get a higher pressure cap if your radiator can handle it, and run your heater wide open...

where is your radiator placement versus the engine? is the engine overheating? what car is the motor in?

i believe the issue here is pressure management since your motor is seeing higher RPMs thus pumping water around the engine at a higher rate. i am with billy in suggesting to get a higher pressure radiator cap first and try again.
