ok, i installed a custom turbo kit over the weekend. the car in N/A form always ran fine and never over heated. After the install we started the car up and it ran fine and boosted 9 to 9.5 psi. The next day i started it up and it ran fine until i redlined it a couple times. Now everytime i start to get on it all it does is overheat. Than i turn the heat on high and it goes down a bit. When i drive normal it doesnt overheat. The coolant is full mixed 50/50. I burped the coolant line as well. The car runs and pulls hard. Please HELP me this is driving me crazy! I know of some possibilities i just need more opinions. Let me know if you need anymore info. Thanks.
Kit includes-
-14b turbo (coolant lines ran on it)
-HF mani
-VAFC hack with dsm 450 blue tops
-fmic
-2.5 in ic pipes
-dsm bov

 

is the reservoir overflowing?....also is there air pressure when opening your radiator cap (after cooling down) after boosting?

it kind of sounds like a headgasket leaking boost in the coolant passages. I've had that happen a couple times

Yes the reservoir is overflowing and pressure when i take off the cap. What can I do to fix it?? replace the headgasket??

 

yep, most likely replace the headgasket.

it should only heat up when you are in boost, so you will probably be ok if you don't get on it a lot. Just incase you can't change it right away.

Even with a bad headgasket could my car still be running good cause it runs good and pulls like a bitch. its just the overheating. this sucks!

 

yeah....my car still pulled pretty well when i had this problem. Its just that after pulling good....temp would always rise a little.

Damn it! Looks like more work on the hatch. How difficult is a HG to replace?? Thanks for your help also i really appriciate it.

 

headgasket shouldnt be too too bad. if that turns out to be your problem. instant message me on aim and ill help you with it

 

Ok, I just fixed a vacuum leak and now the over heating seems not to be as bad for some reason. (maybe do to lower boost?) Only boost to 8 psi instead of 9 to 9.5 now. After the vacuum leak fix it cools down right back to normal when I put my heater on high. This is weird. Anymore input on this would be great before I get a new headgasket as suggested above. Need more info on anything just ask me. Thanks
Some Honda-Tech at the Honda dealership said I am running lean from that dsm injectors. I dont know how that is possible. I checked the plugs and they indicate im running rich. I hear no detonation either.

Bump

 

if the temp is droping with the heater on...

then i'd say you need a better radiator!

Yager-

 

Ok, I tested the coolant with this Mac Tools headgasket leak detector my friend had. It sniffs the coolant, and the results were negative so it must not be a headgasket. I never retarded the timing, could this have anything to do with my engine overheating? Perhaps the coolant heats up to much in the turbo making it overheat?? Please help me out. Thanks

lmao the whole point of running bigger injectors is so that you don't lean out on your stock injectors

 

The problem is not the headgasket it is the stock single-row radiator. You will need to change out the stock radiator to either a fluidyne, C&R, or a more cost effective alternative is to get a delsol two-row. This will allow more coolant to be cooled down as it passes through the radiator unlike the skinny single-row stock jobber. When you boost you are obviously creating more temp. in the cylinders thus transfering to the coolant (to do its intended purpose) yet its not being allowed to cool enough before entering back into the engine. (when those rpm's climb very fast so does the speed of the impellers on the water pump thus pushing that coolant too fast through the boost inadequate stock single-row radiator) Hope this helps you...cant wait to boost on my y8 soon and feel that pull!!

Yeah I looked at a 95 EX radiator yesterday and noticed mine is a little **** compared to it. I'll need to pick one up, but im broke now . Thanks for your help. I hope that solves the prolem. I'll keep you posted. P.s. you are gonna love the boost!

 

Ok after doin another test for the headgasket we realized it was bad. I installed a new oem headgasket along with some arp headstuds. Its now running fine no overheating at all.

 

lucky man . . . . I got a over heating problem myself and can't seem to figure out what the problem is

 

me and my buddy had the same prob i put an teg. rad in and we put a dual row in his and 160 thermostat hope that helps car nevers over heats even on 90 degree days
