Ok, my stock ko3 had been making some noise indicating it was on it's way out, well now its out and has about an inch of shaft play, .

Well my car is due for inspection by the end of the month and I'm thinking of a ko4 upgrade, I know I'm going to get the ko4 and an APR ecu upgrade but what else do I need? I'm talking everything, like oil lines coolant lines, do I need a new "tube that goes from the air box to turbo"? I know I need a down pipe I've heard but luckily mine has a tear in the flex mesh part so I need to replace it anyways, please help just got payed not I need to buy the parts. Thanks in advance!

I would prefer to be emailed not pmed, or you could just reply on the thread whatever works for you. The life of my car is in your hands after all.

edit- figured I might actually need to give out my email for some replys. haha rouches2@gmail.com

 

That should be all you need, i would recommend a new hardware and gasket set, and if you don't already have an upgraded dv now is the time. Fuel injectors might be a good idea too, i would call apr and talk to them about it, you might be able to get more power out of it with just a couple more upgrades.

 

Since I am very late, I hope your problem have been solved. I am interested what you did and how you solved this problem?
