Jake's Epic BMW 135i Build Thread! (5+ Years of Ownership)
-
Are these installed yet? Is it done yet? Are we there yet?
-
I'm imagining you turning into Kurt Russel's character from Death Proof once this is done. But instead of a Nova or Charger it's in a 135i. Not to say your going to turn into a murderer but people may get that feeling after going for a ride.

I think his plan is to see if he can slow down the rotation of the earth.

Lol
No progress yet. Still waiting on the last two batches of parts to come in. Trying to have it back on the road by July.

Stock vs. not stock.

Probably a bit of a heavy assembly. Is it a difficult to reach area for install? I had enough fun with my M20 stuff and there was a lot of room
It's best not to think about it. Even with the subframe dropped there isn't much room to work with in the N5x turbo-side of the engine bay. The problem is only amplified by having a larger turbo housing.
Shop time calls for roughly 11.5 hours +/- to replace/swap turbos on these cars.

Bringing this over to the next page, just because.

As Jordan said, this job sucks. I wish I could say that I already got my stock turbos removed, but the ones in the picture above are from my friends N54.

Finally cleaned the white car this weekend and filled in some small paint chips.

Update on the 135i:
I had a BMW technician friend do some work to the car. I didn't want to deal with dropping the transmission while laying on my back on the floor of my garage. I just wanted to concentrate on the turbo install, so he did the following:
- Replaced upgraded clutch with an even more upgraded clutch (Spec Stage 3+, kept my MFactory SMFW in there)
- New bellhousing bolts, throwout bearing and clutch fork
- Replaced transmission mounts with poly upgraded mounts
- Replaced shifter bushings with upgraded parts
- Replaced rear pinion seal and flush/fill the differential
I picked up the car and expected the clutch to be a pain to drive. Surprisingly it isn't much worse than the OEM 335is/550i clutch. Definitely daily driveable! The shifter feels tighter and notchier, I'm very happy. I put about 30 miles on the clutch and brought the car home to get started on the turbo install. I put the car in the air and took off the front bumper right away.
I don't have the most tools in the world, but I managed to get the subframe and steering rack out in about 4 hours. Another 2 hours and I had the fan, engine mount, downpipes, intercooler, inlets, outlets, water pump, and coolant lines out of the car.
I felt pretty accomplished after all of this. I discovered what coolant tastes like and was covered in grime, but knew I was making good progress. I decided to call it a night and clean up the garage so I could get a fresh start after work tonight again. Next step is to remove the oil pan and replace that gasket, and then remove the stock turbos.

Nice work=) Have you don't any suspension upgrades or a refresh on this yet? I can't imagine how original bushings would feel with all of this power
Nope, all stock. It's lowered on springs, but that's the only "upgrade". I plan to do rear subframe inserts soon because people say really good things about them. A full suspension overhaul is definitely something I want to do, but probably won't happen for another year or two.
-
Were the bushings ever done before you? I can't see them being in all that good of shape now if not
Not that I'm aware of. I'm sure the car could definitely use a refresh...
Green coolant tastes rather nice.
Those pictures scare me, but my ideal car would have 6 feet of clearance on every side of every fastener.
Nice work digging in there!
Sadly, this was the blue stuff. Doesn't taste nearly as good, but thanks!
Any plans for an LSD?
Eventually, yes. I'm sure it will need one. Probably a winter project - I'm tapped for funds right now.
-
I'm really surprised the one series don't have a factory LSD besides the 1M? Is it available as a factory option at least?
