Turbo water lines...how important are they?

[92RT-TT]

I ran a set of 16g's with no water lines. Those turbos had 30k miles on them and still looked new, no shaft play, no issues. So imo I dont think they are necessary as long as you let it cool down first. I always try to take it easy the last mile or so near my house to let them start cooling off early as I figure if I'm boosting its just making them hotter.

TD04's can run with no water as well. It mostly just means oil can coke easier in the turbos, and you need to do the idle cool down when you park.

My understanding as well. I have seen many coolant-less setups work great. Still debating on lines for my Evo3 setup, since I have a turbo timer, they shouldn't be needed.

Just cool down your car sufficiently before shutting it off, and you'll be fine for a few trips. Few months. Few years.

Ok, done. I am going to go unhook my front turbo's coolant lines right now. I just know that one is going to end up giving me trouble and will leak. I guess it is time to actually use my turbo timer :P

I don`t run coolant lines either (WRX CHRA`s which never even had drillings for them..), way I see it is there`s no way I`ll be at sustained high boost within a mile of my house so they`ll always be cool when parked up. If you drive your car flat out right up to your house and then park it you may have bother.

I always run Slikolene Fully Synthetic oil and it`s shown no adverse effects..
