Decided to drop a bit of money on my E82 135i and one of the things Im keen on is improving cooling, is there a recommended path to take for uprated radiators and oil coolers?

I know the 1M had an extra oil cooler and a bigger rad but would they be a straight fit and if so where can I find them? If not is there any other recommendation anyone can give?

Cheers

Regarding radiator mate I'll be getting this one from mishimoto

Maybe my eyes are failing but I could have sworn that said £498 though .............

I've got the twin ER competition cooler setup on mine, which on track works a treat. Takes a longtime to warm up in the winter though.
Looking to swap out the water radiator for an uprated setup soon, as it still hits ~94degs with road driving.

My understanding is the rad is not the problem, but how your map manages your water pump.
Oil cooler is a must, keep the oil cool and your water temps will be easier to manage.

Best advice is to sell yours as is and then buy mine and save yourself thousands

On that note I must remember to wire up my oil temp and oil pressure gauge on my p3cars gauge

Are the majesty Chinese oil coolers good enough? How many rows we looking to use as an upgrade?

I think the stat is as important as the cooler to maintain a given temperature

Bumping this one back up, noticed that even with spirited road driving oil temp is getting up to 120C

Id rather buy one or the other and reckon the rad would be easier to fit and have the advantage of keeping water temps low too, is it going to keep oil temps down enough though?

Do you approve of the oil stat delete mod sold by Burger?

The rad won't be your problem.

My first port of call would be to fit the additional oil cooler from the 1M.

Sam can give you details of this, he's done it to his E87 1M, but the thread doesn't exist so I can't get you details.

By the way 120c oil temp is fine. You need to worry at 140.

The rad won't be the limiting factor at this stage, the cooler will be more so.

The thermostat mod simply increases the time it takes to get to operating temperature. It does not reduce the maximum temperature.

The PPK2 kit for the E-series has a secondary radiator included, but not a secondary oil cooler. Both have their advantages, but if I were to pick one to go for I would certainly do the oil cooler first with a Setrab cooler mounted in one of the lower bumper vents, using AN fitted braided steel lines and a decent t-off plate/block from the stock oil thermostat housing. It's not a difficult mod by any means.

P.S. The larger Mishimoto radiator is notoriously difficult to fit, especially on automatic cars, and the advantages are questionable.

1M has extra water rad NOT an extra oil cooler, and as far as I'm aware the 1M and 135i 6MT rads are the same (there is a different part number for the 135i rad with DCT trans, but I don't think there's any significant difference in cooling ability, just fitment?)

Upgraded oil cooler kits are available from the USA...as well as improved water cooling stuff.

I'm not sure you've got this right. Pretty sure in sams thread he fitted the additional oil cooler not rad. On a standard 135 there is one on the right hand side of the car I believe and the additional one is on the left.

Edit, so it does appear I am wrong according to real oem and the additional radiator is just a normal rad. Maybe this is a place to start?

As a first step I would price up and research the 1M additional coolant radiator as bmw have obviously researched and found that it helps, if they thought an extra/larger oil cooler was more beneficial over the complexity of extra coolant rad then im sure they would of gone that route, although as you have modded your car for more output over a 1M then maybe need to go bigger still, also if you havent had the water pump and stat changed then a refresh of that would also be on cards if it was me to make sure all is tiptop, alternative to the 1M setup is to get a proper upgraded radiator like PWR in there, not cheap but if you want quality it costs.

Reading on some on some tuners websites like Turner motorsports etc in the states they do say stock coolant setup struggles with higher boost, i know they are trying to sell products but what they say does make sense, if you can control coolant temps better it helps keep oil temps in line and you dont want to overcool the oil as it then becomes less efficient.

The 1M additional rad is the same as what came with the BMWP PPKv.2 power upgrade kit for the 135i, it was just standard on the 1M.
You could never order the rad and hoses separately for the 135i, but as it's a standard part for the 1M, you maybe able to from a parts supplier as opposed to a BMW dealer who will often want a 1M VIN number to order parts

alternative to the 1M setup is to get a proper upgraded radiator like PWR in there, not cheap but if you want quality it costs.

Indeed, the PWR rad would be the route I'd be looking at if I was doing it.

Cracking info, cheers

Should start by saying that this is all for track use, when the car is seeing 120 on the road then I think its going to need something to help track temps. I was thinking a 1M rad would be cheaper and easier to fit than an oil cooler but having had a look at the prices .......... PWR want £680 before shipping, I think I need a lie down.
@Element, where have you heard that the Mishimoto isnt all that? I dont fancy even asking what a genuine 1M rad would cost from BMW

As far as oil coolers go a quick research shows the Evolution Raceworks Sports Series cooler kit is recommended and at £550 its not too bad on price either, supposedly it drops oil temps by 10-15 degs on track and road which sounds good to me. Dinan do one but its about twice the money, Stett do one for about £700, I think what Ill do is log oil and water temps with my Cobb device on some spirited driving over the weekend (cheers Rich ) and make a decision next week

I've just checked the part number for the 1M and 135i rad. They're the same..... as I expected.

Why not just buy the additional 1M rad as we've said to start and see how you get on? Currently a genuine BMW on ebay for £160. That's got to be worth a go surely?:

http://www.ebay.co.uk/itm/BMW-E82-E...313763?hash=item1eb053ff63:g:mxQAAOSwu1VW32e7

Then if you're still seeing problems, an additional oil cooler (or uprated oil cooler) is the way to go.

 

[0l0dom0l0]

Another thing, looking at the part numbers for the radiators. The 1M is the same, as I've said, but the auto/ DCT has a different radiator in the 135.

It'll be bigger to cope with the additional cooling required for the DCT/ auto box.

So, you could also try that.

I don't know who make the OEM rads, but I know that when I pulled the rad out my dads 5 series, it was made by BEHR. Genunie BMW rads were ABOUT £500 but buying from Behr directly, I could get the same rad for £150.

So if you were really fussy, you could order a new rad (standard fitment) from an auto trans car and fit that.

But as I said, at this stage, I think the additional 1M rad is the way to go, especially as a genuine one is £160, add the cost of the pipe work and you can be sorted for £250 all in probably.
