Turbo water lines?

[mugen_ctr]

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/force...ant-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.

thanx for the back up deano....lol

pppffft, ametures...lol

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.
