I'm trying to decide which cooling mod or mods to do to my 04 RX8. I've got over 65k on the clock and I'm going to be taking a lot of road trips for work soon. I am worried about the increased heat of playing on the highway for long periods of time.

I was thinking of one of two of the following mods:

Beatrush Under Panel ($180)
RaceRoot's Oil Cooler Fans (Driver/Passenger/BOTH sides) ($195/$390)
RaceRoot's AC Fan Control Unit ($135)
Re-Medy Water Pump/T-Stat Combo ($300)
BHR's Radiator ($550)

Now I am kinda strapped for cash ATM, but which mod/mods would give me the most cooling for the cost?

Any input is appreciated.

 

BHR radiator or koyo radiator.

 

For the money.....since it's tight........I would go with:

RaceRoot's AC Fan Control Unit ($135), but at highway speeds most of the time, this won't be any real issue. If you are stopping at lights and stuff, then the A/C Fan is a good one.

I think the water pump would be the outright best(Mazmart one!)

 

fan control unit is good as well, I only said radiators because you can easily tell if it is working or not and the fact that he listed something up there for $300, but I guess a radiator is still kind of up there in price.

 

Mazmart Water pump / thermostat.
Then BHR Radiator.

I think last on the list would be the oil cooler fans since you're worried about temperatures at highway speeds, I don't see these helping you at all. I think the fans can help in stop-n-go traffic but the airlow is already sufficient at highway speeds. The key at that point is to make sure your coolant temps are under control.

 

You are right about the Oil Fans. At highway speeds they really can't help my overall temp since i'll be moving anywhere from 50mph to 80~mph.

 

that's why they keep me around.

 

btw: I have Mazmart's water pump, thermostat. They're excellent products.

The BHR rad is also an awesome upgrade. I've had it on my car for a while now and I've quite a drop in my coolant temps

 

Hasn't the Koyo radiator been proven to cool worse than the OEM one?

 

small secondary radiator that looks cool and cost less than $100.
It is the most effective cooling mod out there--especially when used with the mazmart pump.

Thats exactly what I wanted to hear. I was about to do some searching, but if Jedi says it, it must be so....

That was another Idea I had, but I have the AEM CAI, I don't know where I could mount a small radiator with the OE front bumper.

 

Yes, I believe that to be a true statement.

 

I did not know it cools worse than the oem one but I thought it was cool for the price. I know BHR works well.

 

The oil cooler fans are not needed in my opinion unless you are a track addict.

 

Just the Mazmart waterpump, and thermostat are the best bang for the buck. My car runs 10-15 degrees cooler on the freeway than before the pump and thermostat. Start with that.

 

thanks L337

 

Perfect.

Np man.

So Easy_E, for the installtion of the Water Pump...

Lets see if I have this right....

Drain all coolant, remove the drive belt(s) (yes?), remove the old water pump and T-Stat, install, re-attach the water pump pulley, and put the belts back on.

Correct?

 

I run a little more distilled water than antifreeze mix. I'm probably at 65 water 35 antifreeze. Although I don't drive it in the winter at all.

 

Don't forget to refill the coolant

 

Alright I just ordered the T-stat from Mazmart and im getting the water pump off kersh4w (THANK YOU).

I found the service manuals and found the water pump removal section. My question is, is there anything I should know before I start unbolting everything? Or if I need a SST or some odd socket size?

 

At track speeds you don't need the oil cooler fans (they might also reduce the flow at high speeds) because you've got enough flow through the oil radiators.
Slightly opening the vents in the wheel wells will help. Not too much though, there should be a diy that shows what i'm meaning.
That's a free mod too!

l337, good choice of products, i love my water pump!
Bhr or mazmart radiator would be the next upgrade. Panels and fans are not going to help much. Instead of wasting money on that you could just save up for an accessPORT and takecare of the fans without having to cut hoses etc

 

I have a AP with MM maps right now. I did see that DIY for the oil coolers, but I don't really want to open those splash guards up to more road debris. The roads in my area are garbage.

I was thinking about replacing the radiator when i hit the 100,xxxmi mark.

But after this, I'll keep up with reliability mods. BHR Ignition, RaceRoot's SyncroSaver, etc.

 

At least you are honest

 

Burn! Sick Burn! I'm coming to this month's meet!

 

I'll believe ye when me **** turns purple n tastes like rainbow sherbert!!!
