for the fc, ...and that will still fit with (mazdatrix's) ss oil cooler lines?

if so, who makes the unit?

What are your current oil temperatures? What is the primary use for this cooler? Drag or road racing?

the stock one is pretty damn big... Why do you need a bigger one? I think some good ducting will probably go farther...

i'm putting a paxton blower on an s5 na, and it's in florida. i dont know what the temps are of the oil, or are going to be when i'm all done, but it couldn't hurt to upgrade, could it? not to mention having extra oil

is there any negitive side effect of getting a larger cooler?

the car is for long, abusive cruises, and whatever else i may feel the need to partake in

the engine is going to be worked, and worked hard whenever i'm in it

You're better off with a custom dual oil cooler setup behind the openings where the fogs are on a s5 bumper. Your lines won't work with this but if you care more about proper cooling than line fitment this is the best choice.

You don't need a large cooler.

Finding a cooler larger then the stocker is going to be bard.

And when you do, it will be expensive. I've seen some direct stock replacements made in Oz but the price is about $800 AUS.

And probably unnecessary as well. The only time you run into oil temp issues is with a FMIC and sustained high RPM driving (ie. on a road course).

The blower isn't going to make near as much power as you think it will. And the power band will be very peaky with a centrifugal blower.

con: Cost of oil change.

I run 6 qaurts and it cost me almost $50 to change the oil myself... :\

i'm putting the e8 stand alone with rb true duals, and street porting the motor, i'm not going for any crazy times. just want something that will be a little more fun to drive.

as for the bumper, i'm putting the fc2000 front on it.

paxton changed their blowers around some, i'm putting the 1200 on, they said it's good for 6-8 psi, and with som etuning and dyno work, and all the other mods, i'm sure it'll be a nice ride.

i'm not too concerned about the money, my fience is fronting the entire bill, and said i can put anyting i want on the car, and i wanted to go a different route then the evil snail. i was thinking, a less evil snail.

Most people in real need of more oil cooling simply run two stock coolers plumbed in parallel.

Mazda Comp used to offer an MFR (Mazda Factory Race) unit that's larger than stock that bolts into the stock position.

thanks.

hey, i saw someone's site, the build up of the dual oil cooler, pic posted below, are one of those coolers larger than the stock one? i went to the site of who makes those, and they seem to have all sizes

what is the capacity of the stock one, so i know how big to get a larger one? is it measured in that it holds x amount of quarts?

I think that initially- especially since you want to use Mazdatrix lines- you might be better served by some creative ducting to the stock cooler (which is giant compared to most OEM units) and take steps to decrease the engine bay heat soak- i.e. vented hood.
This assumes you've already increased the water cooling capacity since the water and oil temps are closely linked.

Do you have A/C? If you plan to keep it, I can see an upgraded oil cooler possibly helping. But I never had cooling problems (once I finally got all the stubborn air bubbles out) with my nearly 400 rwhp T2 using the stock oil cooler, no A/C, and Fluidyne rad--and that is despite a big Greddy 3 row FMIC in front. The stock oil cooler is pretty sick, I've never seen a bigger one on a car before. Upgraded oil coolers are much more important for FD's.

I'll say this again. You don't need a larger cooler.

The only time oil temps are an issue is with a front mounted intercooler under hard driving or with an undersized fan.

First, get an oil temperature gauge and monitor your oil temps. Just adding an oil cooler is going to be useless. You'll add weight, cost and receive no benefit.

At least measure your oil temps before you decide you want to spend time and money on upgrading the cooler.

My car with an FMIC, GT40R, Fluidyne rad, Pontiac 6000 e-fan rarely sees more then 190 degrees of oil temp in traffic. Occasionally I've seen it as high as 220, but not for more then a few seconds after the fan ramps up.

If you track the car hard, then it's quite possible to need more oil cooling, but yes, most people don't need anything but the stock one.

agreed with aaron.....it isnt needed.


90% of the aftermarket or OEM replacement oil coolers for the FC, that i have seen, are hardly any better, if not MUCH worse than your stocker. IF You are worried about oil temps, get a oil filter relocation kit, with lots of hose, and use a larger oil filter. this way you will end up with more oil volume, and more cooling area through the hoses and larger filter.


if you are still worried about temps, get creative. cut out the front 4 plastic bars in the bottom of your bumper, make sure your oil cooler is clean (mine was half caked with 20 years of oil+dirt...) maybe remove the AC if you have it, or make a small air duct to get the air to flow directly to the rad and oil cooler.

ALSO remember that oil temps and water temps are related. excessive heat in your oil will make the engine temps rise....and vice versa. if youve got a good working water system or an aftermarket rad, the oil shouldnt get too hot if the rest of the engine isnt. ofcourse it can get temp spikes if you run hard, but generally it all works out.

(down a lil on the right)

these guys have one but you have to mod it to work with the mazdatrix lines

thanks. i guess i'll first see what the temps are, then decide, but from the sound of it, they'll be fine.
