This is mainly for Boe since I know he water cooled his turbo(anyone can help out if you have input though).
1. Where did you tap the inlet and outlet lines to water cool the turbo?
2. What size hose did you use/prefer/what would benefit us the most?
3. Any other accessories other than hose and fittings needed?

thanks guys/gals

 

bump......anyone?

 

4. what size fittings did you use(3/8" NPT to 90 degree 1/2" hose barb seems to be one of the most common).?
5. what is the size of the turbo oil line fitting(-6 AN or -8 AN)?

 

m tsi turbo kit came with water cooling hoses and stuff, i havent installed it yet , i also need to know where the inlet and out lines need to be tapped

 

I just spliced into the heater core lines... used a 1/2" T and 5/8 hose barb fittings. Came out with -6 fittings used (2) -6female to female hoses about 3.5ft long. Used a 3/8npt to -6 for the turbo then used a -6 female to -6male 90 fitting to elbow it to the drivers side. Fit perfectly had no leaks and didn't effect my heater in the car one bit. Car ran cooler than ever and my spool felt a little quicker.

 

i tapped into teh throttle body lines, the lines were cheaper to replace just incase i need to =P

I thought about that but then i didn't like the flow rate... i figure more is better so i went with the heater core lines.

 

thanks guys.....much needed info!

 

I have been reading about turbos for almost 2 months now. I'm considering building a custom 16g turbo kit. I'm currently routing everything in my head, and came across a problem.

Where do I connect the water cooling lines to?

I searched and came up with this old thread, https://www.evolutionm.net/forums/sh...ad.php?t=96074 I was wondering if Boe's method is still the practiced mode of water cooling, or is there a 'better' way?

 

mine right now are t-ed into the throttle body lines. had leaked at both places when i first had it so i redid them and now they are fine.

 

I merged your thread into this older one since it has some answers already. Boe suggested the heater core lines because they have a higher flow rate, assuming that would be cooler than less flow.

 

Can you take a pic of this for me?


Or is there a pic of the heater core lines?



Thanks

 

Yeah, from my research most DIY kits tap into the TB coolant passages. But that's all the helpful info I've got for yah.

Good luck!

 

+1 on this, i'd like to see some pics of everything hooked up

 

thats the best pic i have for right now. i can prolly take another one after i get off of work
