You all probebly know of my plans for going boost my 'DE this year.
Well I've got my oil lines and stuff together, but
not sure where to get the water lines on-/into. :(
I have seen differend waterline hookups, but I am not sure wich one is best. :confused:
And of course I have used the search, but I found nothing useful.
(Also have read the sticky's and how-to's)

I would like to know from you guys: wich is the best hookup place
(Water in -and out) and please give your motivation,
and maybe a pic of how you did it. It would be appriciated.

Thanks in advance.


Raymond.

It looks like the best way to do it. And the easiest ;)

I do have another question: should I go with the banjo connections
or 90 degree swivel's, what do you think, wich is best?
Examine your setup closely. I had difficulty finding a combination of fittings which would fit without hitting adjacent areas. It took three tries before I found a combination which worked. Hopefully your setup will be easier.

I have examined my setup, (gti-r mani./T28) and I think the banjo's are ok.
Does anyone know the exact threatsize for the banjo's or part# (e.g Earl's)

Water lines are 14x1.5mm, oil side is 12x1.25mm. These bolts/fittings are the same on both the turbo and engine sides.

Earl's makes these fittings. You will find them listed under power steering adapters. Good luck.

Damn TUNER, that Sunny looks absolutely SICK from the rear. I would give my left one for an AWD SR20DET powered hatchback like that.

I think is much easier to plumb it from the throttle body but thats just me.
Yes this is how I've always done it, but I guess the argument here is that water is not always flowing in to these lines, is that correct Lew? I have not studied the coolant flow of the motor, maybe it's time to crack open the FSM tonight and check it out.

Once the car is up to temp I checked the hoses and they were warm so I'd say the water was running through them fairly quickly. I'd like to know if and when the water isn't running through though. HMMMMM.

@ "cnynracer1":
Yes, I understand. Only mine is FWD.
And I hope this year it is going to be SR20DE+Turbo.

@ Everyone:
Hmm, wich coolant lines are it going to be? Throttlebody or heaterhoses?

@ "SERprise In WV":
I have looked trough the earl's catalog, but dit not found banjo's with the 14x1.5mm fittings, maybe is it in a differend measurement given? Or I overlooked it? Someone know the right partnumber ?

All those different measurement stuff, finding the right hosediameter etc.
I am calculating and converting etc. my a$$ off :(

The Earl's fittings are not banjo-type. They are 14x1.5mm-to-XXXNPT or AN type of fittings: You'll need to use a hose end that matches to attach the water line ends.

Read up on my turbo install at this link:

to get an idea of the fittings I used to attach the water and oil lines, then match them up to the Earl's fittings above. That's the best advice I can give you. Good luck.

What direction does the coolant flow through the throttle body? Just wondering as I may be doing that for my brother's install in a couple weeks as well. Is it front to rear?

*****Edit, I found it on your site Greg, day 4! It doesn't matter which way you hook it up for those that are wondering.

I did not connect to the throttle body hoses because they have a thermostatic switch in the line that opens only when the coolant is hot. I wanted water flowing through as soon as the engine started.

You can sort of see the heater hose connections in my original water line page:

http://www.brazosport.edu/~lshadoff/turbo/water.html

in the last two pictures.

Yes I can see it clearly. I guess this is not to much of an issue for me. I just want water to flow through the turbo when I am on the road course! Thanks for letting us know about the thermostatic switch though, I had no idea this existed in our engines!

Ok, if I understand correct...



I need two of these, to put in my turbo for connecting my waterlines onto?
Does this mean that "Earl's -4AN X 1/4npt" is/has an 14x1.5mm fitting for the fitting-hole in the turbo?

(For a guy like me, born in the metric-minded part of the world, it is all a bit of "ala-kaa-zam" it's kinda hard to see all this. :( )

@ "SERprise In WV":
Why is it that you ordered 1 x 90 deg. and a 1 x 120 deg. hose adapter
instead of 2 x 90 degr. was there not enough room for a 90 degr. piece?
