Size Of Oil Cooler

[CarRacer]

I'm going to get a air cooler for my oil setup. I purchased a 90 filter housing.

I'm putting together the other pieces and I'm trying to use stuff that I have laying around my shop.

I have a tranny cooler off of a domestic that's quite large. I plan on using a oil thermostat, like Cy has on his car. That's a really smart idea, due to the climate we live in. I'm just worried that even with the thermostat, the cooler will be too efficient.

Size is 14.5 x 10 inches.

thats huge man!!

i'm in texas and dont need anything that big. we got 110 weeks here.

I used a 13-row Mocal unit from Summit or RPW. No gauge to see if it actually helped to lower oil temps or how effective it is/was, but I made it through two seasons of events with no issues. As I understand, the 90 filter housing already has a t-stat inside, so my big one that we installed inline is redundant. You don't need two, but let someone else confirm that the housing has a t-stat inside of it.

There is a cooler bypass valve that's temp sensitive IIRC.

 

[CarRacer]

Is that the valve we port to lower oil pressure?

 

i used this ams oil cooler kit. comes with more than enough hose and all the fittings.

 

[Dialcaliper]

Definitely not.

The one you want to port is the "relief valve" that dumps back into the pan.

^^ Correct, here's a picture of the relief valve porting area and location located at the rear ( or closest to the crank pulley ):



The picture from Chris above with the braided line shows the bypass valve directly below the lines ( looks like a big castle nut with plastic cover ).

Here is a jdm one for reference :

I'll be sourcing all my parts from leftovers in my shop. Thanks for the offer though G.

As for porting and any information related to the 90 OFH, I found this thread to be the best.

If the oil thermostat would be redundant, I could build this one for the price of the adapter fittings to the housing. Pops offered some leftover -10 hose from his Camaro build. I'm not sure if I'll even use that hose though, as the tranny cooler has no provisions for AN fittings. I might get a different cooler though. I'm sure Summit has some for under $50.

maybe consider going with a stock rx7 setup. its huge

and mounts an lines look easy

the 90 housing has a thermostat inside and only puts 10% of the oil through the cooler if it's below 180*

Unless you think you might need a smaller radiator in the winter because your car runs too cold too /ubbthreads/images/graemlins/hsugh.gif

Fact is, thermostats are in there to keep fluids at a set temp, not super cool or let them get hot. Pretty nifty.

Are you planning on running a 90 housing, or something else?
