I replaced my radiator two summers ago with another OEM radiator, but now that my Integra is turbo, I am worried about how much boost it will hold. My whole motor will be fully rebuilt and plan on boosting no more then 12psi.

stock radiator will hold 7-10 lbs on daily driven well tuned, maybe 12lbs at tracks. It's all about the tuning, make sure you have a perfect water/anti-freeze mix. lol

Most people used fluidyne radiators. I dont think there is hp range in which a radiator will blow-up. Most people with bolt-ons kits use their stock radiator.

they are only a few hundred dollars to upgrade, something i would do with anything over 200-250 hp...

As long as your headgasket holds up then a stock radiator will be good for 60psi, give or take a couple...

falcongsr

in other words....your radiator shouldn't be seeing boost!

*15psi
after that boost starts to leak out of it..

but you dont want to blow a head gasket with a stock radiator for the chance of poping the top off and shooting coolant everywhere. A aftermarket one will just ballon out.

Well, my OEM radiator handled 7psi last summer, and I'm putting on a new OEM headgasket and headstuds, so it shouldn't leak out.

hehe *grins*

Something about this thread makes me laugh...

All I wanted to know was when to worry about my OEM radiator blowing, and I get 10 different responses out of it.

I wouldn't worry about a stock radiator failing on a boosted engine unless you were subjecting it to hot track laps on a regular basis. You should be good to go

I plan on running a stoc civic radiator. I went way over budget a long time ago and honestly dont think ill need it for the short time it will be running on a drag car.

thats because the "how much boost?.......... etc." question is the main cause for litter on internet message boards. i thought honda drivers were smarter then the rest but nope, 95% crap burying the 5% of real information just like every other board.

p.s. Tony, damn you, haha. the first thing I thought was a smart-assed head gasket comment and you beat me to it. by about a week too, just like I get beat by a week by quick class hondas to the end of the 1/2.

if you blow your HG, the radiator will be the least of your troubles

Im sitting here thinking.. wtf? i know he isnt going to try to use a rad for a...
Yea the PWR flows better than stock..eheh..

I've had better luck with 10w-30 radiator oil at high boost levels. 2 quarts is usually enough to get the job done.

did you ever get the answer to your question?

rioninja

heheh.

Seriously though, there is a simple way to figure it out.
If you find your fan coming on after boosting, or while your NOT in traffic, then your radiator is too small.

Im running a new stock full length radiator in my CRX, and never had a problem with overheating. But, EF radiators are about twice the size of newer civic ones

what does your radiator have to do with your head gasket?

BlueShadow

At 12 PSI on an LS you're only pushing around 300 WHP +/-. So unless you plan on doing a lot of road racing, auto-x, lots and lots of drag racing or one really long WOT pull then a stock radiator will work. An aluminum rad will work better because no plastic endtanks to crack. You also might run a little cooler, and the rad might be less heatsoaked if you get an alum rad.

Why did you bump a 2 year old post to say this?

Your rad is related to blow HG's because if you blow a HG all that combustion pressure can get into your cooling system with nowhere to go.

Oh boy I thought this thread looked familiar
