Thats not normal. Change rad fluid...
How are you running the fuel management? Running Lean?
I usually see those stock radiator do fine with boost, locally. So im sure that wont be to big of a problem.

Re: is overheating normal after installing turbo? (synik)
im only running an fmu but its rich all the way to redline...also im running a slim fan but im not sure what brand it is. is anyone else only running one fan or am i supposed to be using two? maybe one in front and one in back of the radiator. could the intercooler be restricting airflow to the radiator?

Re: is overheating normal after installing turbo? (Jeffescortlx)
the timing is the same as before it started overheating...im not sure what its at but it was marked so i put the dizzy back to where it was set...but i did add a blaster ss coil to my 6a which was running with the stock coil before...i cant remember if it was overheating before or after i installed the coil...

Re: is overheating normal after installing turbo? (kun3racer)
after it cools down (test drive) im gonna take the top radiator hose off and spray water into it to see if the coolant flows well out of the head...or ill remove both hoses and see if it flows well out the other end

Re: is overheating normal after installing turbo? (kun3racer)
Not to be negative, but is you overflow tank filling up (could be lifting head under boost)?

Re: is overheating normal after installing turbo? (kun3racer)
there are several factory here.
is this a custom kit or a manufactured kit?
what kind of boost are you running?
are you using an intercooler?
when was the last time you flushed your coolant system?
is your coolant level low all the time? when was the last time you put on a new rad. cap?
when I went to 9+psi on my old greddy setup, i was forced to upgrade to a larger racing radiator because of flow issues. not so much cooling, but the stocker flows like (_)_). yea like (_)_). the end tanks haev tiny 1.5" openings and then cut down to 1.25 in the plastic end tank. so if you get a newer larger one you get like 1.75 to 1.75+ endtank that can more than handle the flow.
finally are you running properly mixed coolant?

its a custom kit running 7psi and a small fmic. the coolant is never low and i flushed it like 5 months ago. also ive been boosting for about a year with no probs till now. oh the cap was changed about the same time as the flush
no its not filling up

Re: is overheating normal after installing turbo? (kun3racer)
Check your oil and coolant to see if they are mixing at all. I've seen this type of thing a few times. Mostly it was a head gasket problem becuase the head lifted slightly, people don't retorque their heads like they should. Another time it was a bad radiator.

I would replace that first, because it is cheap and easy, and also a possibility.

Re: (CivicGSR225)
you shouldn't be overheating with the turbo kit.
1. put a thermostat back in there, shame on you. If you're super paranoid just get a 180 degree stat.
2. Fill the radiator all the way up to the tip top and leave the cap off. Crank the engine. If water starts spraying all over the place or bubbles quite a bit then you've got a blown head gasket.
3. If you have to, remove the turbo kit temporarily and go back to stock and see if it continues to overheat. If it does then you know the turbo was not a factor and there's another underlying problem that just happened to pop up out of coincidence.

1st> Never run w/o a thermostat on the street.
2nd> Ditch any SOHC rad you have, you pretty much NEED a B series Rad or even better an aftermarket one! SOHC ones are really 2 small and unless you are getting really good airflow! They have a tendency to slightly over heat! Let me guess, you are running a bar & plate intercooler that pretty much fills up the hole in the front bumper
3rd> Straight water always runs cooler
Try mixing like 25%fluid 75%watter!
UNLESS it’s really cold where you are!
Also how do you know its running rich? Please dont come back and say because of your A/F gauge or the black smoke out of the fart pipe

the water stays pretty calm until i rev it then it overflows but theres no bubbles at all. i just assumed that it was from the water pump pushing.

i'm supprised no one has mentioned how sensitive they are to air in the cooling system.
my stock b18 will overheat like hell if there's air in the system
park your car front end first up a big hill (or use jackstands/ramps) run it up to temp.. then right next to the upper hose coming out of the head.. turn the bleeder on the cooling system.. have someone rev it to like 2k or so.. when your shooting a stedy stream.. tighten it up...
its easy.. and will also let ya know if your fan is kickin in or not

Re: is overheating normal after installing turbo? (kun3racer)
in the beginning when it started to overheat i would turn on the heater and it would cool down really quick. now it takes a long time to cool down so im assuming that the water pump isnt pushing it through the heater core as quick as before.
