Radiator Cap

After chatting on a thread yesterday I have now been told that the non turbo rad cap should be 0.9bar. I have also been told by Toyota that it should be 1.1bar. Searching the net brings up all different answers.

 

So i was wondering if n/a people could tell me what they have on their car currently. :) Cheers in advance.

Anyone else :)

 

TRD do a 1.3 bar high pressure cap, reason behind the high pressure cap is to keep the coolant in the system longer to allow it to cool more ; just go Stock OEM as the high pressure will result in unnecessary pressure in the system and put unnecessary strain on the heater matrix/Components

 

Long story short go with what Toyota says 1.1 bar ,I think its safe to say they know what they are talking about :)
