reversing water inlet on EJ20 TT?
72RSbug - May 8th, 2005 at 06:14 PM

I've seen it done on this forum but not on a twin turbo engine.
From what I can see on my TT is that the second turbo would be in the way but could be wrong.
Can anyone clear this up for me before I take of the intake manifold and find out it doesn't work?
thanks

I am in the middle of doing this on my EJ20T (single turbo). I have cut it and tack MIG welded ready for proper TIG welding. I will extend the wiring for the two sensors and hopefully reposition the small feed by the intake.
Maybe with my pics you will be able to work out if you have room...

PS I'll put up pics later today

Hope they help!

Thanks for the helpful pics ricola,If that end piece can be fitted on a slightly larger angle it might work.
I'll check with a local company that makes aloy stuff and see if they could weld it on for me.

It is quite tight to get the outlet missing everything. The fuel rail gets quite close if you were to change the angle too much from what I have.

I've just had mine welded, we decided not to try and move the take-off for the intake manifold as we don't want to risk leaking, I'll just extend the pipe.

The water on the subaru goes in at the bottom ( thermostat ) and out at the top ? me think


72RSbug - May 10th, 2005 at 02:08 AM

the thermostat is indeed at the bottom right side of the engine but from what I've seen (could be wrong here) the thermostat opens up when the coolant inside the engine reaches a certain temperature and let it flow towards the radiator making it the coolant outlet.

The hot water flows out of the top of the engine, however, the temperature is controlled by regulating the amount of cool water being taken in at the bottom of the engine by the thermostat. So, I think we are really talking about the coolant outlet manifold...

I took another look at the twin turbo and I really don't any way it could clear the second turbo.

I assume the "outlet" tube on top of the engine would stick out the rear of the bug when left unmodified, that wouldn't look good at all :jesus

Most of the cars I have seen use the stock coolant manifold, they normally use a 90 degree bend which goes downwards and presumably around the engine towards the front again. I think it probably goes across the back behind the valance to a similar position as the inlet where they both go towards the front. Don't worry, it doesn't stick out of the bodywork!

give you some ideas


72RSbug - May 11th, 2005 at 05:37 AM

That's nicely done seagull, is that aluminium or galvanised steal tubing?
I was hoping I could have aluminium tubes bent for coolant lines but was told they might nog be strong enough and wouldn't bend properly

The pipe work is 316 L stainless steel tube
this is the radator I have made ,three row with electric fan .
