No oil cooler. Invest $80 in a Turbo Timer (allows the car to run wo the key in) and you'll avoid a repair later in life (if you still have the car then). I have min eset for 30 sec on (less then 90deg) hour drives and less, and 1:15 for anything more. You can customize them just about anyway you can think. The fan running is for the radiator and engine. Mine runs for like a minute or so. I'm not so sure on the water and oil thing...I'm pretty sure its an oil cooled turbo (I cant see coolant being anywhere near it-oil and coolant dont mix all that well).

 

well what kind of turbo timers do you guys have installed? does it make a difference wat type it is?

 

Try GReddy, HKS or APexi (quality circuit boards). Doesnt matter which you choose, stick with a brand kinda thing (ie, HKS exhaust, timer, turbos, GReddy timer, gauges and BOV). I have the GReddy and found its easy to use (like most) and installs quickly enough.

 

ive heard that some ppl have been having problems with the greddy tt, most ppl are startin to go towards Haltech
