plumbing in a turbo - Saxperience

jsdvtr · 13th August 2012, 18:59

How is the best way of running the water feed and return to and from a turbo?

Where from and to?

What should i use for running lines from coolant system, t piece?

Anyone?

plumb into the heater lines is easiest. You don't want to use an inline t, you want to force water through the turbo. Extend the matrix lines to the turbo, then from turbo to matrix again. It can be done in a tidy way. You may see photos of people who have just put a T in the matrix line but this wont force water through the turbo, as the water will just flow through the T on the path of least resistance.

Mines t'd in

With a restrictor in the to persuade the majority of the water through the turbo and let a small amount head straight through the T

Got any pictures?

Is it best to do before or after the engines in?

This is the ticket.

Would the T piece go in the hose from radiator into back of engine or one from back of engine to heater matrix?

What would you use to restrict it?

Matrix

I used a copper washer betteen the T pieces

Good idea that blackie

Iirc shaun (106moaners) took his originally from the top rad hose but IMO its easier to use the matrix lines like blackie and I. Pipe size is similar etc.

Advantage is also warm air quicker thanks to toasty turbo

Yeah it's mint in the winter

In theory.

Just tee in to the line, the system runs at pressure, so it will flow. The vts oil cooler is a prime example, it'll be fine. Your best off looking to direct water from the bottom of the rad or before it enters the engine as the heater pipes have already come from the engine so they are hot.

What size T piece will i need? I know the T off will need to be same size as the feed to turbo which is between 12-13mm. Just need the main part to be the ID of the hose to heater.

I was also told i could do it from the header tank, not sure if this for the feed or return (if it had 2 outlets aswell as overflow).

Ross^p · 17th August 2012, 19:36

I'm not with the car at the mo so going from memory I think it's 17 or 18mm? Blackie will know off the top of his head I suspect when he gets notified about the thread.

e8_pqck · 17th August 2012, 20:37

Edit! i'm guessing 17mm. Had the outlets modified on an alloy rad once but can't remember what they were!

blackie_2k5 · 17th August 2012, 20:42

i think its between 17-19mm

i bought 19mm outer diameter T's iirc? struggled but got them on, the outlet and pipe im pretty sure should be 19..but id imagine i struggled as the pipes have probs shrank a bit over the years

Something like this be ok for the coolant feed and return?

Struggling to find correct size t piece though.

The outer diameter of the feed on my turbo is 13mm so that means i need a 13mm water lines and a 13mm t off.

blackie_2k5 · 25th August 2012, 12:32

If its 13mm then that's the size you want mate

The pipes you want you should get made from a hose place local to you, decide which type of fitting your going to use to connect to the turbo (i used banjo bolts)

Decide how you'll connect the pipe to the t pieces.. I got straight hose tails and use some extra pipe and jubilees

Go to your hose place and get them to make the pipes in the correct length you'll need them in nylon water pipe with stainless over braid, silicone would melt being that close to the turbo
