what does this mean? "4rum"
Also the coolant inlet and outlet does not matter too much on the turbo side since you could have it bottom mounted or top mounted. The oil is the most important, make sure you have the correct oil restrictor for the ball bearing turbo.
And if you dont want to use the boost controlled simply DO NOT install it. You can use the stock actuator thats on the s14 turbo and be done with it.
