i'm about to do this as well. for the water outlet of the turbo, i would have guessed to tap into the hose which goes from the water outlet on the back of the head (next to firewall) to the thermostat. for the feed i would have guessed to tap into the hose from the water pump?

 

not entirely sure how your setup is at the moment, but mine has no heater hoses attached.

i have been told there is no in and out of the turbo so it don't matter where you put the in and out of the turbo

is this true and if not which 1 is in and out on the turbo side???

 

I'm not running a thermostat and the hoses that come off back of head i have blocked as it was hitting firewall as its in a small car

 

I'm running similar to you at the moment

1 is coming off the bottom radiator hose that feeds water pump

the other is running to the back of the water neck on top hose where them hoses off back of the head originaly run to.

 

is this ok???

 

also

 

where is the original thermostat located???

 

thanks mate

what car is it in?

 

i'm not sure where the thermostat was original, i have a 4ac thermostat and used a photo on the Witzl's guide on toymods. i thought you had to have the water outlet on the back of the head coming back to the thermostat?

don't quote me as i could be wrong but that sounds wrong to me

the outlet on back of head with 2 sensors feeds hot water back into head when cold to reduce hot spots

the 2 sensors are not needed when using a aftermarket ecu as I'm using a vn como sensor in different location

so i blocked off

 

as for thermostat

where are you running it now as there deigned to stop flow to heat engine up quicker then when hot open up to let cool water flow through engine to cool down

so i don't get why you would have conected back of head to thermostat as it would defeat the purpose

 

so if your not sure where it was originally \where are you running it now???

I'm not sure about the hole inlet outlet thing or if it matters,

 

My water lines are plumbed from the outlet on the back of the head, and there's a hose fitting on the side of the block just behind the outlet for the oil sender. Not sure myself if this is an ideal setup, but it's doing the job so far.

i thought the connection from the back of the head was to allow water to flow around the head (even before the thermostat opens)

 

 

mine is similar to this setup (taken from witzl's guide)

ok that makes sence the way you have it

and yes thats what the pipe on back of head does i just worded it different to you

and what cars does that thermostat come off(year,make,model) as i may make a similar setup

 

now

my water lines go to

where you wrote cut these oulets here and here(pipe goes to back of the top radiator neck)

other goes to where you wrote(bottom radiator hose) i made a t piece in between 2 radiator hoses which on your picture would be between the radiator and your thermostat

IS THIS CORRECT????????????????????????????????

 

 

as for hrv oos

i was originally going to put where you did but from factory it looks like its some kind of bleeding valve located between oil filter and oil turbo and gauge outlet

 

which should i do or should i leave it

I'm parranoid as when i start it for a few seconds turbo pipes and exhaust side of head gets extremely hot and i put a gauge where outlet goes and its 20 to 40 deg hotter then engine temp
