Tapping into 4AGE block for water feed/return

[daveskatesallday]

I don't have heater or A/C. Was wondering where most people tap into the block for coolant for turbo lines.

Anyone have pics maybe?

I teed into my heater lines. Since you aren't running a heater why not just devote that whole circuit?
If I was in your place I'd probably weld or braze AN fittings where the heater hoses connected.

Oh yea, I was thinking 20v. If you are 16v then run the line from the throttlebody to the turbo.

that could happen, the heater lines run to the back of the block correct? I never had heater so I really don't know

also I have a T25 (SR20 redtop) turbo, some people have told me that I can get away with running just an Oil Feed & Return line with no problem, of course I'd like the extra cooling for peace of mind but my main concern is getting the car started first but I do want to look into the coolant lines if it is that necessary

If you use the iacv/throttle body lines make sure hard lines aren't gummed up (common problem). I'd do what the guy above said and use the old heater feed/return points for the turbo.

I'd personally go with a turbo that's oil cooled only for simplicity, but that's a subjective thing. It's probably not a good idea to run oil only on a turbo that was designed for oil and water.

Yea I might consider doing that, I may even just get the car running first then go back and add the coolant lines it shouldn't take too long I'd assume.It does have the oil and coolant ports BUT I've known some 240 guys to run without the coolant lines with no issues and have beaten on them. I'd like the peace of mind though so i'll definitely see what I can do

The water lines are primarily to prevent long term coking of the oil and this is the worst on shut downs.
If you are religious about letting the car cool down before turning it off you will have less to worry about. If you don't mid risking blocking off the oil passages in your turbo some day go for it.
Really though I wouldn't. Might as well try and extend it's life as much as possible.

If you decide to go AN and want someone to weld some nice fittings on your heater inlet and outlet let me know.

I understand thanks for the info I'm sure I won't run it too long without coolant lines going into the turbo

sent you a pm btw

It would be nicer to pickup coolant from the block rather then stuff already heated up in the head.

true but would it really matter that much? some ppl get away without running coolant and have no issues

it would be convenient from the back of the block so you wouldn't have to run lines from the intake side all the way over to the turbo
