built gsr block aebs iron sleeves b16 head running 23 lbs on garret gt30r hybrid s300. car was completly tunned and runs like a top

problem is when i go in to boost it over heats waaaay 2 much...
i was told the coolent lines to the turbo are put in the wrong places well the return line it goes back to the im by the thermosta

is that route correct?

what set ups are you guys running ?


thanks for the help i can get pics up if needed

 

Just throwing this out there because I'm not familiar with B16's, but on an H22, the temp sensor is right next to the thermostat. So if it's similar on a b16, and you have the return line coming back right by the temp sensor, it will be reading alllll the hot coolant coming out of the turbo, as opposed to the "actual" engine coolant temp

Just an idea

 

thanks ,, i was thinkin bout that also, the temp on the b16 head is about 7 inches away in the middle of the side of the head any other opinions?

 

Coolant low, maybe a head gasket issue?

 

I run a gsr with a GT3076R and I use the B&R kit. It uses the block for feed and radiator for return. Simple and clean.

head gasget is perfect i run a racing antifreze it helped lower the temp quite a bit its alcohol based yea the coolent was the first thing i checked its fine



thanks ima try 2 find another route for thes dam lines

 

bump

 

Where are each of the two ends connected?

I've been thinking about mine. I just took the lines that normally go the throttle body and put them to turbo instead. I'm beginning to think about it and I don't think it's a good idea. I think with it set up like this, coolant comes out of the head and goes thru the turbo... then back into the waterpipe to be pumped thru the block without going thru the radiator.

If yours is like that, I could definitely see it causing problems.

 

no my return line goes to the inmanifold write by the thermostate the feed line come from the lower portion of the of the back of the block
thats how the shop build the line connections

 

Hmm... I'd have to see a photo of it to have any more input for this.

 

i have a 2.0L lsvtec with a top mount gt3076r and I have the coolant lines tee'd off the heater core hoses off the fire wall works great never had a problem.

 

is your block sleeved and do you ever read hot when going into high boost?

 

Yeah its sleeved no cooling problems and it never gets over normal operating temp.

 

retorque your head. seen it a few times under long periods of boost your pumping air into the coolent system causing bubbles then you get off boost and temp returns to normal. never comes up on a comp test either. you said your sleeved, but what kind of head gasket? O ringed? what was it torqued to? just my past experiences.

 

Exactly!!!! right when i get off boost it imedietly starts to cool down usually after a pass its super hot but when its dne its starts to cool . but also some hot days yes i live in yuma az its still 80's i c it get hot not that the car is adailly driver but we i do tend too take it out more then i should latley


ima get some pics up now of the set up so you H-T guru's (chough) shodan (ehhhaa cough)
can get a lil more of an idea what it might be b4 i decide to pull the cams off to retourqe th

 

here a few kinda crappy pics of the set up hope they help

 

pics no response?????/

 

How does the coolant route through the head once it enters? Does it quickly go by the coolant temp sending sensor for your dash?

I'm more afraid of the hose close to your turbo manifold that would bake and bust fluids all over your bay and cook your turbo.

 

well it goes strait to the im in the port on the head but the thermostate,

as for the hose bieng close to the manifold it just looks that way dnt get me wrong it close but the portion is actually wrapped in heat wrap and ive put plenty of time on that hose and i also pre op/check the lines b4 and after becuase of previous leaks

 

I was asking how the coolant routes through the head upon entering from the IM area above the thermostat. If the coolant gets routed to the coolant temp sensor right away then that would explain why you are seeing a quick rise in temp while boosting.

 

yes it does but wouldent that be pouring hot water straight in to the head ?
bad idea huugh?
