As you all know Evolution 6 speed trannys are notorious for crapping out on the track due to 4th gear heat issues. I track the hell out of my Evo. In order to try and hang on to my 6 speed as long as I can I am building a tranny cooler. I got the idea from a fellow Evo owner on the board (QuickOne). I want to give a big thanks to MCS Motorsports (www.mtbuggies.com) for the sponsorship on all the Earls fittings and lines. All the brackets/mounts turned out amazing.Today I got the cooler mounted and pump mounted. Tomorrow wire it up/install a switch in the car and plumb all the lines and done All keep the pics coming.

The Car.


Pic of the front before anything was touched.


First things first. In order to get the Fluidyne cooler to fit properly a section of the original mounting tab had to be cut and new holes re drilled.




Next was to create a bracket for the cooler to rest on. Opted to make this piece out of mild steel. Once the piece was fitted it was marked and drilled.


Since the lower bracket is mounted into a boxed part of the Evo's body (can't access to put a nut on or thread it) I used self expanding rubber pieces that are threaded on the inside.


What the bracket looks like installed.

Next we fabbed up the mount for the oil pump.

This is a pic before the bracket was made. We used 3 existing mounting point to build upon. Used mild steel strap to create the bracket.

Next a bracket had to created so that the pump had a mounting surface (This was plug welded.)



Fast forward. Bracket painted and pump mounted. Looks factory.

 

Update: Finished

Ran into a slight problem with the original mounting bracket. I had some clearance issues with the bumper therefore I had to drop the cooler down a 1 1/2".


Therefore lowering the bracket


Thanks to SW20-AE86 for making the lines for me

AND DONE!!!

 

That's pretty sick, I'm sure if you're willing to mass produce it, there's going to be MR owners out there that are willing to buy it.

Other's might think different, but I think that's a great job.

 

 

How much did this setup cost and how much extra fluid capacity are you going to have? I've thought of doing this too, glad to see someone testing. Is there any danger of starving the tranny with the pump?

 

estimated cost? i work at a shop so labor, materials, etc... will be cheap. just tell me around what it cost you. very nice work btw!

 

Count me in for one!

 

nice

 

Awsome set-up I would love to get my hands on something like this!!!!

 

I have about $350 into it. (Mind you I got all the earls lines and fittings free through my buddy) With that said Parts would be around $450-$475 plus fabricating costs if you don't build it your self. As far as fluid it adds about 1 extra quart. Starvation is not an issue since 1 extra quart has been added.

 

how hott does the tranny get @ the track? would be interesting if you could install a temp sensor to see how effective this pump is...i have the same parts and wanted to try it but wasn't sure how much it would benefit...great work though!

 

you can count on a couple hundred deg

 

OT: Where did you find that tow hook?
And how did you mount it, weld to crossbar?
any info is appreciated greatly.
Nice work BTW on that tranny cooler.
I want one too for my MR....

 

it's bolted on by 3 bolts/nuts on the cross member...look at the first couple of pics.

a couple of hundred degrees?...reason why i ask is because the pumps operating temps...and it keeps a constant temp of about 265degF or 130degC....if its beyond these limits the pump could fail....unless the effiency of the cooler keeps it well below this threshold...i guess we wont know until he takes it out to the track

 

thx, didn't see that pic.
looks sweet.
