Im stumped on this one guys, im not sure which IACV water line to tee off for my turbo water lines...
Which one do i cut an take a feed/drain route?
Ive got some idea because of this: http://www.d-series.org/forums/forced-induction/126928-how-hook-up-turbo-coolant-lines.html
But that setup looks different to my D16y8 setup and IACV :/

use the water line.from.bottom.of throttle body and the one that goes to the i let manifold/head lext to heater hose....

DONT TAP IN the throttle body
completely remove the throttle body from the loop
Just use the in & out off the block

ive never heard of ppl using this method... most ppl from wat ive read jus tee off the block an back into the rad, which i wont do since mine is oem plastic item rad, an 2nd i wouldnt know where or how to tap into the block lol

From that pic, you could use either.

keeping the throttle body in the loop adds un-wanted heat to the whole setup
= Less power
Just follow the lines man...

Whilst this is correct, i haven't seen anyone prove that there are any gains to be had on a Turbocharged car (Because of the hotter intake charge)

its more to prevent overheating than anything but why add heat when its so simple to remove in this case

not sure bout this convo...
but regardless where u take coolant from on the engine for the turbo....
ur coolant system is governed by a thermostat...so regardless wat theories are out there....
ur coolant temp will alwaysb roughly at ur thermostat's operating temps...

Guys
Think of it this way!!!!!!!!!!
You pay $$$ for an intercooler too cool your intake air down so why would you want to heat the same air up again as it goes passed the throttle body if left in the coolant loop?
No one in their right mind leaves the TB in the coolant loop when plumbing the turbo lines

I believe this setup with the D is different to say a B. As in the photo the IACV bolted to the underneath of the TB so you can't exactly isolate the TB from water entering it (thats how I see it). On a B you can totally isolate/bypass the TB because there is a hose from the TB to the IACV.
Removing the heated water lines from the TB is a good thing for performance. Who cares about proving it, to be honest, yes, its negligible and you probably would not see any gain at all. But it certainly a step in the right direction rather than a backward one. All little negligible gains add up to a larger one.

D and B are the same round abouts from memory
I did the same setup for my Turbo D16Y1 then my turbo B16A I believe
But yeah remove heat whenever possible IMO

ahhh cheers guys some good information.... ill def need to look into routing it from the block, once i get the car up 2morrw to bolt up most of the gear up

Nar, my B18C7 is different to the pic on 1st page, not sure about other B's.

My b16a2 i just closed off the coolant like Luke did.
I actually did this before i boosted it even. Had no issues.
He is right every little bit helps. The coolant to the TB is for japanese conditions where temps get below zero to stop a frozen TB.
Doesn't really happen in AU. ALso if you've boosted your car, lack of heat is certainly not a problem.
