1G Fp turbo coolant lines or no coolant lines

[Bird58]

Hey guys, I’ve been trying to get as much advice as I can before I keep going. I’m near to completing my 4g63 build but running into questions if I should runcoolant lines for my freshly rebuilt FP Red. The reason why I’m leaning towards NO coolant is because I already shaved and welded all the nipples shut on the water pipe and also running a FF OFH.
My 1gb will be driven more on a day off cruise/NE Dragway and a couple car meets. Spring to fall then put away to hibernate in this wonderful Massachusetts unpredictable weather . I know and heard to let the car idle for a least 3-5 of not more minutes before shutting down on hard passes

I would like to hear your opinions and or experience thx in advance

below is a pick of my water pipe

Water isn't needed if you are going to properly cool the turbo before turning the car off.

No coolant- it's only necessary for hot shutdowns or endurance racing. Ball bearing turbos require coolant due to the tiny fraction of oil they pass, but journal bearing turbos are fine...especially those fed from the filter housing.

No need to waste fuel idling for 3-5 minutes unless you're doing boosted pulls into your driveway.

Follow @JusMX141 's advice. I run Holsets and no coolant. I don't do a pull on the way home, turn in and shut the car off though. If you do a pull, let the car cool and you will be fine, if like said, feeding from the OFH for more pressure. I pull in, let the car idle down and settle in and shut her off. No turbo timer crap just common sense for your turbo. It is daily driven (when it is running and not having issues) to the store, fast food etc. No real cool down when you are just driving like a normal person.
