Deleting Inlet Side Water Lines? Rb25Det

[midnight]

Hi guys did a search but couldnt find much...

I want to delete as many coolant lines as possible under the plenum on a s1 rb25det...

I ditched the heater core and currently the lines are just looped, but im wondering what I need to keep / what I can block. and the cleanest way to do this...

thanks.

Id be plumbing the lines back into each other so you dont air lock the system. Are you keeping the throttle body heater line?

no its aftermarket plenum so thats already gone.

I found a picture of the lines on a 25..

can I just loop the 2 big ports, and use the small port (next to the water outlet neck) for my turbo water feed?

the big ones are fine to link, as to the small one im not 100% does it come from a similar place in the water jacket compared to stock turbo feed? if that makes sense. all would depend if you got enough flow through it maybe someone else can confirm

ive just got my bigger 5/8(i think) fittings looped with a bit of hose. The smaller 5/16 fitting is just blanked off.

You can use the factory turbo water fitting on the exhaust side of block and if needed (depending on plenum) use the smaller fitting off thermostat housing as the other water feed
