Default B-Line Motorsports Top Mount Oil Cooler Installed (With picts and video)

(This is pretty long so skip to the bottom for picts and cliff notes)

For several years I have been experiencing pretty excessive oil temps at the track (road course) so I decided to start looking for an oil cooler for my 2005 STI. I really wanted to mount the cooler in the hood scoop but I didn't want to go trough the trouble of fabbing up a custom bracket system. Fortunately I discovered the B-Line Motorsports top mount oil cooler kit and decided to order one. The standard kit includes a 25 row Setrab oil cooler, a set of extremely high quality fire resistant -8 AN lines that come pre-assembled with all the AN fittings, silver fire shield for the 3ft of the lines that are near the exhaust, a standard sandwich adapter (not a thermostatic adapter) and the custom mounting brackets for top mount fitment.

The kit retails for $565 but I was able to get it through a vendor here on Nasioc for $500 shipped plus and extra $25 for the upgrade to a thermostatic sandwich adapter. The only part of the kit that is 100% exclusive to B-Line are the custom mounting brackets. If you wanted to fab up the brackets your self you could easily save a few bucks by getting all the items from racerpartswholesale.com.

The kit came with easy to follow picture base instructions however, the kit was so simple to install that I did little more than skim through them before I started wrenching. Even though it was not in the instructions I attempted to prime the oil system before starting the car the first time just like you would for a new turbo or something. I unplugged the fuel pump relay harness (under the glove box) and cranked the motor for 30 seconds and waited two minutes before cranking it again. It was my intent to to do this for five cycles but during the third cranking cycle I discovered that something was very wrong with the B-Line supplied thermostatic sandwich adapter! I started to hear a sound similar to the noise that comes out of a squeeze bottle of mustard when its nearly empty (splattering and spitting with air mixed in). I got out of the car and looked under engine only to see lots of super expensive Motul oil shooting EVERYWHERE! After some investigation I discovered that the B-Line supplied thermostatic sandwich adapter had a design defect causing it to leak oil between the adapter and the oil filter. I immediately called B-Line and told them what was going on. The guy who answered the phone was very apologetic and promised to get to the bottom of the situation very quickly. We talked through the situation and concluded that the thermostat adapter would need replaced. Since they only had defective thermostat adapters in stock he opted to temporarily overnight me the standard non-thermostat adapter at their cost which I could then use until they figured out what to do.

I got the new adapter the very next day and repeated the install just the same as before. I was very glad I decided to prime the oil system because I didn't see any oil pressure at all until nearly the end of the THIRD cycle (~85 seconds of cranking). During the entire 4th and 5th cycles of cranking I saw about 65psi of pressure so I figured that it was safe to start the car. The initial startup was uneventful but I did notice that my oil pressure was down about 15psi from where it had previously been. FYI, I monitor the oil pressure using a defi oil pressure sensor in the rear oil gallery plug.

After the car came up to temp and I was 100% sure that there were no leaks I when out for a drive. The oil pressure was about normal for idle and light cruse so I decided to do a few pulls. After seeing that my oil pressure was down nearly 20PSI from normal at redline I became pretty concerned and headed home. I also noticed that my oil temps were starting to get very low (under 165F) which also concerned me. I kind of expected the low temps but the low pressure at redline was a real shocker. After researching my situation for a few nights I called B-Line back and explained the situation to the same guy as before. He was again very apologetic and told me that he would need to consult some of the other guys that he works with for advice. While I waited for a call back from B-Line I decided to give BAT Inc. a call to see what they had to say about the situation. Knowing that BAT had years and years of motorsports experience with oil coolers I figured that they would be able to help.

The sales guy from BAT was extremely helpful and made a number of suggestions starting with an upgrade to -10 AN lines. He also told me that the sandwich adapter that I was using (non-thermostatic) was of very low quality (it looked pretty ghetto) and was likely a large portion of my problem. He also suggested that I remove the factory oil/coolant heat exchanger since it would help cancel out some of the pressure drop experienced when installing an aftermarket oil cooler. Since I didn't have very much confidence in the sandwich adapters that B-Line was selling I opted to purchase a 200F MOCAL adapter from BAT. I went with the higher temp adapter because the BAT sales rep told me that the Setrab cooler would be "extremely efficient" when placed in the hood scoop and that a 180F adapter would most likely continue to allow the oil to go below optimal operating temp. MOCAL adapters use special dowty seal based fittings so I had them include a set that terminated in -10 AN (these are the black fittings directly on the adapter).

Once I got off the phone with BAT I decided to call B-Line up again to work out some kind of deal to get my project moving forward again. After all the trouble I had they were pretty eager to work something out which made me very happy. I was able to return both the sandwich adapters I got from B-Line, all the -8 AN fittings, hose etc so I ended up keeping ONLY the Setrab cooler and the custom brackets. In return, they "upgraded" me to all -10 AN hoses, fittings for a marginal fee equal to the sale price difference less the cost of the thermostatic sandwich adapter that I originally purchased. Even though the experience was far from perfect, I am impressed with the customer service at B-Line.

After receiving everything, I removed the factory heat exchanger and did a more or less custom install (didn't follow the B-Line instructions at all) using the new -10 AN hardware and the MOCAL adapter. The picts and the video do a pretty good job of showing what I ended up with and how I ran the lines.

Here is a bit of oil pressure and temp data from some testing I did today:

-100% cold start (not run in 24 hours): 98PSI / Ambient Temp
-Full temp idle (after driving for 10 miles and sitting for 1min): 40PSI / 194F (No change from pre-oil cooler temps)
-Full temp cruse at 65mph: 84PSI / 180F (10F drop in temp)
-Full temp at stock 7200 RPM redline (after several pulls on the highway): 90PSI / 190F (20F drop in temp)
-After 20min of hot laps on a road course track: SOON!


I am extremely pleased with the results. I basically have zero pressure drop from stock and oil temps


Cliff notes:

The standard B-Line top mount kit has insufficiently sized hoses and a low quality sandwich adapter that causes low oil temps and excessive oil pressure drop. Upgrading to the -10 AN line option and using a high quality MOCAL sandwich adapter (sourced elsewhere) makes the kit just about perfect. The center coupler needed to attach an aftermarket oil sandwich adapter directly to the block is Subaru part number 15018AA050.

The customer service at B-Line is excellent.

BAT Inc. is a great source for a proper sandwich adapter.

I'll be the first to say that it looks cool. Some people go for the stealthy look with their FMIC but when one looks into the scoop and doesn't see a TM..dead give-away. IMO this kinda hides that, functionality seems to be appropriate, and it looks pretty clean for being located front and center on the motor!

Looks like a very clean set up. I like how it turned out. I have been looking into getting a oil cooler for my Car as well. how much did that set up cost you?

I have the motor out of the car for a scheduled rebuild (not failure induced) so I figured I would snap a few picts. During the rebuild I added a KillerB oil pan and pickup so I decided to grind just a bit off the bolt on the end of the sandwich adapter. Here are some updated picts:

Hi Guys

I just added this fantastic thing to my car, I must say that is a great oil cooler. The only I will point out is that is not a perfect fit I din't have problems with the sandwich plate but my mechanic had to cut the screws (the black alen ones of the base) because they were to long and didn't get to the end of the base/stand on the manifold. Also we choose to run the lines on the right side of the car instead on the left like the manual said (this because of my headers). Finally I had to cut a little of the metal margin on the plastic hood scoop because it rubs a little with the base nuts when the engine shakes, other than that no problems or leaks so far.





I also added a ghetto style waterspray setup with coax cable nipple and some old boost hoses I found on my toolbox and it work fine. Best part it cost me $0.00 so I am happy with the results.

Dexterous, Figu,

This is a pretty straight forward and reasonable setup if you have the application! I insist on asking what your primary motivations were for choosing B-Line? Clearly the top-mount brackets are the only thing unique to this package as dexterous stated below. He also mentioned he didn't want to take the time with custom fabrication, which certainly understandable. I guess I'm getting at, is really not just going with a complete custom setup best? I need to price all this stuff and I would be nice to re-post those for the sake of others, but it is difficult to see what the "appropriate" application is here. Supposedly B-Line is a reliable company and sounds like it is working well for the both you. My 02 AWD Drift WRX build is going to require some power down the road and this is one area that I feel is subject to a WIIIDE range possibilities involved with oil cooling. So if I choose another option, what are your opinions on this? I will take your advice dex and talk with BAT, but I'm concerned. I need an unshakable product and it seems that having the cooler further back is better than running everything from the bumper. But to cut to the chase top-mount takes the risk out of smashing it to pieces in a crash!!! Oh nooos. I'm frustrated, yada yada ya... it all makes since though as long as you two think the results are in outstanding comparison to say a water/oil cooler radiator setup or front-mount setup. It just seems so clean and lowers the risk factor. I have to replace my oil pan and this is just annoying, I don't want to do this right now. Oil cooler education pleeeaase?

Also what oil pressure gauges are yall using? Of course this is 2.0 so idk about the -10 AN, are you running -8 AN Figu?

Also will get prices up on custom fab asap.

I guess I'll chime in as well.

I saw the B-Line kit a few years ago and really wanted to design my own, but time constraints prevented that, so I called them and ordered just the brackets and designed my own kit around that with a Mocal sandwich adapter and -10AN lines.

At the same time I figured that if I was going to mess with the oil system, I might as well install the accusump I was eying.

After I had everything installed, I found the location of the cooler to be sub par for my application, it was simply sitting too proud, as in too high in the scoop, causing air to hit the front rather than the fins of the cooler. So I took a saw and chopped some of the "feet" of the bracket, about an 1" worth, until the cooler was almost flush with the hood.

I drove the car for a few weeks like that, noticing a big improvement in oil temps, about a 20F reduction and never going over 210F on the track, where with the stock cooler I was sometimes hitting 230F.
This was all with a scoop without TMIC internals.

Then I figured it could not hurt to install the scoop internals and modify them to fit... Best idea ever! The temps dropped another 20F! The general rule of thumb I found is that the oil temps, after warm up, are now at about ambient +100F. This means that if I'm cruising at 60mph and it's 60F out, the oil is 160F. But on the track it never get's over 200F.

I am currently designing some machined brackets that will allow a 25 degree tilt, and about 1" fwd/aft movement of the cooler, to align the fins in the airflow better.

As for the person who said that the TMOC heat soaks, yes that's true, but it only takes about 15 seconds or less, depending on RPM, to get the oil temps down.

All in all, a great idea that still can use some refinement, but works great as is.

My setup:

Looks great, exactly what I want to do. I'm hoping I can get the stock engine cover on to maximize the ducting from the hood scoop

Is this something you might sell? I'd be very interested in a set.
