radiator choice

supradrift · 05-18-2007, 10:48 PM

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.

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.
