The problem is you would still need the adapter plate, the oil lines to the thermostat, then find a way to get your oil lines to mate with the stock adapters. I think the cost would be about as high as this kit will cost. If you buy the kit, you trade in your stock oil cooler for a Setrab. |

I knew I had seen pics before of the OC t-stat...I had saved them on my computer from another thread either on this forum or on the other one. If you don't mind me posting them in your thread then here they are, otherwise I can remove them...save you some work anyway
For those asking, I would think you wouldn't want to completely delete the T-stat. For one thing it allows quicker oil warm-up, which is useful since the oil is working best when warm...and it could help build up oil pressure quicker when cold as well, since allowing oil through the oil cooler right away would mean a pressure drop for the system potentially.

Do you have the link where you can buy the kit? I don't see it on their site.

If you don't mind me asking, what did the whole kit cost you?

I wonder how much of the secondary oil cooler retrofit kit is actually necessary to do this?

Good review as always!
My two favorite things about this kit, is the overall lower oil temps and the Stett adapter plate! That little plate looks pretty damn cool!!

The kits are going to be a lot cheaper than AR's kit
If I recall it was under 600 for stage 1 before the GB Check the old thread or maybe its in my pms some where

As always Very well done .
It would probly be easyer to get a volunteer to do the same test and log for us on there stock oil set up. With the temps dropping around the country, to give us an idea of the how much the temps made a difference. As a fellow modder it is hard enough to get things just right with out the addition of taking pictures and logging everything, in between the four letter words, I really appreciate your time . Thankyou Sir |

Wow! Thanks for taking the time to do these reviews.
I don't know how you have the patience to take all the photos during the process. When I wanted to do my own slide show of installing and uninstalling parts, I am too impatient to take the time and snap a few photos... |

Not sure I like the idea of lowering the oil temp that much. I would imagine BMW had it in that range for a reason, and I seriously doubt oil temp affects emissions. Coolant temp yes because it directly affects proper combustion, oil temp I doubt it.
Also, there seems like there's quite a bit of fab work involved for the replacement. The Dinan kit seems to mount to all stock locations, but I can't tell if requires the removal of the front crash bar to install it or not, although that doesn't seem to be the case. Obviously this kit requires the bar to be removed because it mounts behind it, but I can't tell from the install if that was required to remove the stock oil cooler or not. Another question I have is why everyone is caught up on the Setrab oil coolers. It's not they are the only company to make high quality high pressure oil coolers. Derale has made them for years and their cores certainly cost quite a bit less. I guess I just don't see the appeal of paying that much extra for an oil cooler just for a name. Based on the pics of the stock oil t-stat, a properly sized replacement spring could do the trick if you just want to lower the temps without the hole filter housing replacement. Sounds like a fun project to me. |

Amazing review as usual! With the lower oil temperatures, the oil viscosity will be different. If our engines are indeed designed to be run at a specific temperature with specific oils (LL-01 approved), then will you consider using a different brand/weight of oil that has similar characteristics at the lower temperatures?

Another point to consider is that since the pistons are oil cooled, you can also change the heat expansion tolerance that pistons were designed for to not have piston slap. In a non-oiled cooled piston motor, typically the piston design would include greater tolerance to allow for greater heat expansion of the hotter aluminum vs. a piston that is being cooled which will not expand as much. Personally I plan on trying to come up with my own setup that uses a high efficient 25-27 row core, and hopefully won't require massive amounts of car manipulation to make it fit. We'll see what happens. Does the Stett kit include a proper louvered vent? Or is it pretty much just hack a hole in the back and let the hot air hit the rotor? I'm not sure I like how the air guide is just removed as well. Obviously it will still get air, but not as efficient as with a proper air guide. Granted none of that matters on the street, but running 30 minute sessions on the track with 100F + temps can find the weakness of any setup. Last edited by C4sF80M3; 12-04-2010 at 08:47 AM..

c4s335i,
If you think the additional oil cooler kits are not limping at the track, I think you should dig a little deeper. All I am hearing is that they are limping. Quote:
