radiator choice
 

i have an 87 turbo and the radiator started leaking, so i had it epoxied. turns out the epoxy only lasted a few months, now i am looking for a new radiator. In the future i plan on building the motor to about 400 whp but since the radiator is leaking now i am going to replace it. when i rebuild the motor will i have to buy a high performance radiator? id rather buy it now instead of buying the stock one then find out i need the nice aluminum one.
any information on this will be appreciated.

I'm running a Koyo and I'm very pleased with it. The Koyo isn't a 100% direct fit, you need to shave a little rubber off the lower mounts, add a plug from a subaru to the temp sensor location (unless you're adding a temp sensor or going 1JZ) and add a small piece of metal to clamp the aux fan down at the bottom... all in all it took me about 30 minutes.

There are really only a few choices when it comes to preformance rads that are made for our car or that fit with minimal effort. Koyo, PWR and I can't recall the other I was just thinking of.

The Koyo can be had for just a little more over what a replacement stocker would run... I'm referring to replacements without plastic endtanks. Replacement rads with the plastic end tanks cost about as much as they're worth.

I have a koyo on my 1jz car and a Fluydine on my 7m. Both work great, the koyo looks a little better if that matters to you.

There is no temp sensor on a 7M radiator.

All the temp sending units are on the water outlet housing or the thermostat housing. Even the low coolant sending unit is on the coolant recovery bottle so I have no clue what you are talking about.

Lol.!!!!

That's some funny stuff.

Yup, that's why you need to plug the hole on the Koyo rad that's for the 1JZ's sensor. :P

????????? ??

I was referring to HH saying he didn't know what the guy was talking about.

I thought it was funny because that exactlly what I said to myself when I finished reading it. So I'm not as big a tard as I thought I was is all.

is there any modifying to be done to put a fluidyne in? and are there any advantages to putting it in, so if i put more hp in my car will the radiator be necessary or will a stock replacement hold up?

The OEM rad is a pretty good unit. However, if you've got to replace it going with something with better cooling, higher capacity and less weight is always a plus. Especially since the price isn't much more.

If you just want to stick with the stocker you could always rebuild it.... that's right it's rebuildable. Look in the TSRM and EPC for info.


EDIT: IIRC, the fluidyne drops right in.

so your saying that eventually its going to need better cooling anyway right??

I'm saying that what you're going to *need* will depend on your build. BUT, if you're going with a new rad might as well pay a few extra bucks and get a good quality high flow one and have all the bases covered from the start.

EDIT: Also, since you're going to have to drain the system, you might as well take the opportunity to flush the system well, replace the thermostat and rad cap. ;)

well thanks for the help im going to go with the fluidyne and see what happens

thank you for the input everybody, i went with the fluidyne and so far i am happy with it i put it in no problems everything worked great and looks awesome just to let anybody thinking about a radiator it is worth the money

do you have an electric fan to go with it? i heard going electric add up to 15hp rather than using a belt driven fan.

Radiator
 

I went with a CSF Racing radiator! They make the stock replacement and within the last 2 yrs started making drop-in race radiators for the 7M. Cost is great and so is performance!

i jsy got a new head gasket fixed n i got a new radiator after that n just today my radiator blew up i thought it was the engine dump that blew but wen i refilled the radiator it kept leakin n never filled up....did my radiator blew out i think but im wonderin wat was the cause does anyone have a clue o n i filled it up with 50/50 coolent so pls help im fucken pissed n confused

did it start to heat up did you notice when it happened? repair leak let it run see if it heats up for the price of a thermostat i would start there.if its another bad head gasket after you repair the leak check the over flow see if its bubbling like there is compression in there
