Jake's Epic BMW 135i Build Thread! (5+ Years of Ownership)

Yay for no more clutch slippage! So its looks like you just simply pulled the valve out and reconnected the lines? I've had customer's tell me they replaced the line with the E92 M3 line as they didn't come with CDV's.
Haven't heard of swapping the line, I know plenty of people have to pulled it out and re-connected the lines. Exactly what I did and works fine

It made me giggly. I did 6 gallons of 93 and 2 gallons of E85.
I am still a bit on the fence for running some e85. You had no issues at all? How close to empty were you and how many gallons does your tank hold?

I've put E85 in every tank since I installed JB4. As long as you're on map 5, you have nothing to worry about. I have had no issues at all.
I just PM'd you back, but forgot that you have a bigger tank than I do. Mine holds about 14 gallons. Also, you don't need to run 93, but I like to because it allows for more power.
With that in mind, here is what I PM'd you:
someone said:
I started with a 30% mix, but have ran as high as 45% mix already. I started with 6 gallons of 93 and 2 gallons of E85 from an empty tank for a ~33% mix. My last tank I did 8 gallons of 93 and 6 gallons of E85 from an empty tank for a ~43% mix.
Just make sure you add the 93 octane first. Then once you put the E85 in, do three 3rd gear WOT pulls from 2K RPMs up close to the redline. A good spot to do these is on a highway onramp. This allows JB4 to autotune to whatever gas you're running. You'll notice as you do more pulls, it feels slightly stronger.
Map 5 with E85 is significantly quicker than map 1. It's hard to go back. If you have a USB cable, it wouldn't be a bad idea to datalog. That way if for some reason it doesn't feel right, you can see what's going on. If your HPFP is dying, it might struggle with the E85, but otherwise you'll be just fine. Post back and let me know how it goes!

Did you notice a difference between the 33% & 43% mix?
I think I'm gonna mix it up when I fill up for the trip down to Scooters.

videos are a must!

Yeah, I think there were a few extra ponies coming out. Boost was a tad higher because it autotuned to the mixture.
I'd start with a ~30% mix your first time just to make sure everything goes as planned.
videos are a must!
Soon, I'm working on it
-
Yea on n54tining.com under the jb4 stuff written up by BMS it says you can run 30-40% with no worries so I think I'm going to split that and run a 35% mix.

What are you doing this weekend? I have saturday off, so we should assemble the crew for beer and hookah and do car videos
or sunday
or friday
This is a possibility. I'll hit up you.

Here is a photo until I install the downpipes and E85 fuel pump.

Unnf. This car though.

I installed my ZHP shift knob today.
Before: worn BMW Performance shift knob
Oooo, what's this? Excuse the fingerprints all over the top.
And installed... still fingerprints.

Much better! That old knob was ugly and probably way over priced!

Looks great!

Thanks guys, I agree!
I decided that I was gonna try to install the downpipes today. A few friends came over to give a hand... all of which are BMW owners.
On the forums, most people say that installing downpipes is a major pain-in-the-ass. They noted that they would rather pay someone else do it if they ever had to do it again. I went into this expecting it to take a while.
We grabbed gaskets from AutoZone, ordered pizza, and slowly got started around 1:45pm.
We were very lazy throughout the whole process. Ended up getting most of the bolts off, but one in particular was giving us trouble. It was in a horrible spot and we (aka Ben) rounded the nut off. This really held things up, so why not take a break and light up the hookah? Please note: Ben under the car realizing he really fucked up
Getting dark now... better get back at it. We ended up having to torch the shit out of it and use an air chisel to snap the stud/nut.
After we got that out of the way, we still needed to unbolt brackets, v-bands, four O2 sensors, and unhook the whole exhaust from the hangers. We even had to unbolt the steering rack and move it out of the way for more room. Maybe we should have started earlier?
Believe it or not, I did work. I just snapped some pictures throughout the day as I got tools and drinks. I wish I would have taken more pics (as always with projects).
I think around 10:00pm we finally got the catted downpipes out. I was hoping the car would be buttoned up and back on the road by this time.
Enough for tonight. Back at it again tomorrow after work...

I can't believe how quickly your making progress on her! ย I've always thought these looked like a Bulldog.

I have discovered you can't even get exhaust manifolds off of an m50 without unbolting the right engine mount and lifting the engine an inch.ย I can imagine how cramped it is in there after several more years of engineering...
It's not so bad where they connect to the exhaust (minus 1 bolt), but it's blinding trying to take off and put on the v-bands up where the turbos are. The bolts and O2 sensors are a pain.ย

I can't believe it either, I wasn't planning on very many mods but I can't stop now.
The downpipes are finally in.
Also, I don't have a picture of them, but I wet-sanded and polished my exhaust tips since we removed the exhaust. They were black and caked with crap. I always assumed my exhaust was some sort of custom setup but as I cleaned the tips they revealed a "Riss Racing" stamp. Sure enough, this thing has a $1300 3" catback exhaust!
And as promised, a short teaser video. I only recorded these to show what it sounds like in and out of the car.
Excuse my excitement as I grannyshift up the onramp, I've never lost traction in 3rd like that before.
(I'm not sure why my voice sounds weird right at the beginning)
After this video I put bus lengths on a new Camaro a few times from 50-120mph as he tried messing around with me. I'll drop the E85 fuel pump in next week and reflash the ECU more aggressively. Can't wait to hit up the strip and get her on the dyno again.

Where is the video?
Way to get this thing into beast mode so quickly!
