sorry but....

 

Ya................

You really should put your underbelly tray back on.

But to help: Koyo>Fluidyne

 

I can't believe that your taking it to a shop before you even know exactly whats wrong. Jack up the car and take a look, see exactly what happened under there..

 

That, or, don't drift near objects.

 

your hose probably did crack, it was just dark that time. it happened to my friend when he drifted. ended up being a cracked heater hose after i checked it

 

Do they sell underbelly trays still? I remember my friend going to a drift gymkhana, he didn't have one on his 240, cone came right under and clip his alternator belt. Sucked to change in 0 degree weather.(Ka24)

I would like to buy one!

 

I drift in my TII and I run a Griffin aluminum race radiator that was meant for a 350ci V8. No complaints here and it's cheaper than either the Koyo or the Fluidyne. Plus from what I have seen, it's a better quality than either of them. The downfall is if you don't have the know how to make your own mounting brackets. But it would only cost about $50 from a machine shop to have them make some for you. That would be my suggestion. I run the Griffin with a Flex-a-lite Black Magic fan and I have ABSOLUTELY NO OVERHEATNG PROBLEMS. Just my experience. Best of luck to you.

Why would I change a rad unless it's bad?

One other minor point on the Fluidyne. The overflow fitting is a 1/16" NPT nipple, available at any Home Depot. Since it's already threaded for 1/16" NPT, it's very easy to adapt for use with AN fittings. The Koyo requires you to either braze on a new fitting, or simply clamp the hose. I'm trying to eliminate virtually all clamped connections for reliability, so this is important to me.

 

FWIW, I've run my Fluidyne for a couple of years now with ZERO problems. Fitment is perfect. Quality is incredible.

During the time I've had it, I've had a stock 13B-T, a 1/2 BP 13B-RE and now a 20B. I'm finally starting to run into some issues with heat and so I'm going to sell my Fluidyne so I can pick up a custom, larger core radiator.

If anyone is interested in the radiator, it will be available after this weekend for $325 shipped in the US. There is nothing wrong with it structurally. It doesn't leak at ALL. There are some bent fins, but it is all cosmetic.

I have a k2RD rad....No matter how hard I get on it....she never goes above 180*.

 

I wouldn't reccomend a steel radiator for the rx7. Seems like my car wants to get hot in the 90 degree weather, either with the a/c or not. WIth the a/c on, it gets worse. I chose Fludiyne cause i had the extra bucks. I should be getting in the mail soon

 

There is a Fluidyne for sale on the second gen parts list for $320 ,no replys might check it out quick before its gone...
