1 Series M Coupe stock front mount an upgrade for a 335i

TwinSnails · 04-11-2011, 10:27 PM

I like the idea that my car as stock as possible, saves me the hassle of changing the car back to stock form before taking it into the dealer. I've been a bit hesitant to get an aftermarket IC because I'm a bit nervous as to what the dealer will think, but would like like an alternative over the restrictive stock IC. Possibly the front mount from a 1 Series M Coupe? I would imagine that Bmw would make it larger than the stock 335i IC, it definitely looks larger.

The stock 335i IC is: 7620 cm3.

Do anyone know the size of the 1 Series M coupe stock front mount? Checked real oem w/ no luck.

I wouldn't be surprised if it was the same. They took the engine and cooling parts from the 335is / Z4 and those don't have upgraded intercoolers. We'll see soon, but I fear it might be the same.

don't believe so

i believe they are the same, but the 335is has more cooling features than the 335i.

Forget the intercooler! I want to know if the differential from the 1M is transplantable into the 335i!

just as much as the one from the M3 is

Agreed swapping that diff would be EPIC

Sure, but they must have designed new half shafts in order to fit the M3 diff into the 1M. As far as I can remember, it was the difference in the half shafts that prevents us from bolting up an M3 diff into our 335.

Just go quaife.. Easy and works great with less maintenance. Only professional drivers would feel a slight improvement with the m diff.

BMWeber · 04-12-2011, 12:32 PM

the whole rear end of the 1M, sub frame differential and all are identical to an M3 so transplanting a 1M diff would be the same as a M3 diff.

The half shafts of the M3 fit in the 335. They do not fit in the 135 as it has shorter half shafts and differently designed hubs.
The only custom thing that needs to be made is the propshaft from M3 to 335.

As for the 1m diff I am sure it will bolt in with its own driveshafts. Don't know about prop compatibility though as I believe the 1M is using a M3 gearbox so the lengths are going to be wonky.

Blk07335i · 04-12-2011, 02:19 PM

Confirmed...intercoolers are the same from 335i to 335is so I would assume that the 1M has the same one.

They have bigger OIL coolers I believe, not FMIC.

968tomr · 04-12-2011, 02:32 PM

Are the same changes as the 335is and z4 Sdrive 35is - new cooling fan, remapped water pump, and a secondary water radiator on the drivers side of the car. It is similar to the BMW Performance Power Kit available through BMW Performance from a cooling perspective. Very different from a drive-line perspective though.

I hate to be off topic but just a quick comment. have you researched this at all? because just about every thing you just said is incorrect. do a little research and few part number comparisons

zsapphire7 · 04-12-2011, 03:23 PM

what i want is the 1M steering rack

Sorry whilst you where comparing part numbers I was busy fitting the M3 diff to my car. I should of phrased it that the half shaft does not go in as deep in a 135 therefore it has not enough space to push in a M3 shaft. But what do I know.

I think I miss stated my point or did not give enough information. the only difference in the 335i rear and a 135i rear end is the actual hub. 335i and 135i use the same shafts, wheel carriers, subframe, suspension links virtually the same. seeing as I have fit 335i hubs to my 135i to give me the ability to use a wheel with a 10mm lower offset. and in the proses I bought the whole rear of a 335i to make sure I did not have any issues. and plan to switch to an M setup in the future and the only sure way to fit a M3 or 1M diff is to have the entire M setup subframe, diff, shafts, hubs and wheel carrier.

so my comments were in you referring to the 135i being different to the 335i and also the 1M uses the same transmission as the 135i. in general the 135i and 335i are identical under the body 95% of the parts are the same

the 1M has the same bolt pattern as the 335i on the gearbox output flange (105mm instead of 110mm for the M3)
