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.

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

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!
