Hi guys i got an edelbrock turbo kit installed on my 2000 civic ex a/t. problem is the car overheats. I believe it overheats for 2 possible reasons 1: the exhuast 2.25'' magnaflow exhuast is too restrictive. 2: the tranny is cooled via the radiator and is not big enough to cool the tranny/turbo/engine.
question: Can my 2.25' exhuaust be causing the overheating do to too much backpressure

Im guessing the fix (other than getting a 5spd which i will be getting on SOON.)
would be getting a 3'' exhaust
or a trans cooler but i dont really want a trans cooler since i will be getting the 5spd soon.


thanks guys... please keep ur negative **** out of this thread.

 

is your overflow tank getting full once you notice it start to over heat?

 

i ran a 2.25" catback on my 07 si turbo for a long time, and when i switched to a 3" i noticed no real changes in terms of heat generated.

i dont really know the layout of the 2000 civics, but i'm assuming the exhaust manifold on the front of the block near the radiator like most hondas? if it is, i would highly suggest wrapping all of your exhaust components and getting a turbo blanket

 

I know for a fact that your exhaust is not causing you to overheat unless you have a cat in there.

Do you compression test. If you didn't use aftermarket headbolts then you already know why its over heating.

and is this car an automatic? If not, there is no transcooling going on unless you put one in.

 

Blown headgasket due to a poor tune and the car trying to run too much timing in boost.

 

isnt the tranny cooled by the radiator? cause thats what i meant... and was thinking a transcooler would keep it at norm temps.


the turbo manifold also gets pretty hot... like glowing red after driving it like 1/2mi.

it doesnt overheat when its not moving.. I can leave it on in park and it wont get hot at all
hope that helps a bit. thanks guys

 

FYI, auto trannys have coolent lines that run in them. 5-speed standard trannys dosn't have coolent lines.. Also i can garrente that is NOT your problem, and having back pressue isnt going to give you cooling problems aswell. Make sure your coolent level and oil level is good. Any leaks? also make sure all fans are working properly and blead coolent if needed. hope this helps.

 

Compression test and test coolant system pressure. I hate to seem short, but this happens a lot with Dseries engines.

 

is your coolant bottle overflowing when this happens?

 

This would be my guess as well

 

Its also not under any kind of load/stress as it sits there and idles. The exhaust isn't your issue.. Neither is the auto tranny cooler. Follow some advice. You asked, but then you don't want to hear what people are telling you.

Auto Honda trannies SUCK when it comes to large power increases. Simple I/H/E can hose these trannies. Your first order of business is to correct the overheating issue, then you should do whatever you can to get that 5 speed swap done ASAP. This isn't going to be anywhere near a reliable setup until you do.
