I agree as far as motor operation is concerned, I was strictly talking about driveshaft/ujoint angle… that’s independent of chassis angle.
ehh…chassis angle affects the angle the motor is set at, which has an effect on the angles of the drive shaft in that it determines what has to happen with the rear diff.
i wasnt just responding to your post, it was more so this:
you want to level the car not on the wheels from the frame.
IE jack stands.
this car does not have a live axle in it.
OP, is that a cue ball for the shifter? i used an 8 ball before, actually quite comfortable lol
It’s not a physical cue ball, but a Hurst (style) shift knob. I was going to do black but wanted it to stand out a bit in the interior. Mine doesn’t have the logo.
Halfway through building manifolds/headers now. 2-1/4” mandrel bent mild steel that will be welded to the OEM BMW ball flange for compatibility with the stock exhaust. The 1 piece BMW headerback exhaust is staying almost nearly stock, with the exceptions of the modifications I made to it over the last year or two, which includes a 3” QTP cutout y –pipe before the Y-res, deleted scuba tanks, and Y-res converted to M5 style by adding a turndown in the “dead end” portion (dual dumps now instead of single). If you count the cutout pipe, I actually have 3 dumps underneath the car. I plan on welding a 3 bolt flange (have a few laying around) to the Y-res dumps so that I can tune the exhaust sound to my liking by simply adding a cap-off plate where necessary.
I was searching for a stock LS1 fuel rail/injectors online, and stumbled upon a screaming deal for an LS6 intake, throttle body, higher flowing Ford injectors, and OEM fuel rail for $300 shipped. Can’t beat that. It’ll be here tomorrow.
Took the day off on MLK Jr day. Bundled up with my fiancée (only about 20*F here this week) and drove out to the metal yard to scrap the BMW pre-cats in the headers. $75 for both.
Next stop was the junkyard. Grabbed a set of 8 EV1 injector pigtails and 90* intake elbow off a 1998 Cadillac Deville, a set of slim(ish) cooling fans out of a 2005ish Monte Carlo (along with mounting brackets, rubber isolators, and harness/pigtails), and a M60 intake manifold off an E32 that I will sell. I may be back to grab a few more things off the E32, namely the magnesium valve covers, the OEM HID headlights, a sidemarker, and anything else that I can sell. What an odd design throughout that engine bay. Brake booster by the headlights, coolant tank by the cowl, front hinged hood. Cool stuff.
Wish we had more euro-based u-pull yards locally, I forgot how much fun (and how cheap) it was to go “pickin”.
The JY in Bergen has a random selection of bmw/audi stuff from time to time…
Since it’s too cold to work in the garage and fab the manifolds, I figured I’d start on the harness in my living room.
few questions regarding wiring the LQ4.
I’m at the point in my swap where I’d like to start cleaning up the GM harness for use in my car.
I don’t want to tackle GM w/ BMW wiring integration yet, because I’d like to have a cleaned up GM harness first. The harness I have is an uncut, OEM stock harness that came with my LQ4–all out of a 2003 Chevy Express Van. I’d like to unwrap my harness, remove any unnecessary circuits/connectors (depin them as well) and shorten/lengthen the remainder of the GM harness to fit the dimensions of my engine bay.
The harness PCM connectors are BLUE/GREEN on my harness, so I’m following this website for reference:
I am using this website for all my reference.
http://www.lt1swap.com/2004vortec_pcm.htm
I am running a T56 from a 2002 Camaro SS for trans.
Ok, now that the backstory is through 
1. Which circuits are unnecessary for this swap?
Right off the bat, I plan on deleting the 2nd O2 sensors and VATS when I have the PCM tuned.
I would assume these are the 2nd O2 pins to be removed?
Pin 25 TAN 1671 HO2S Low Signal - Bank 2 Sensor 2
Pin 28 TAN/WHT 1669 HO2S Low Signal - Bank 1 Sensor 2
Is VATS only removed via tune, or are there wires as well to remove from the harness?
What about removing anything in the harness labeled for automatic transmission?
For example,
Pin 32 Transmission Range Switch Signal A (A/T)
Pin 72 Transmission Range Switch Signal B (A/T)
Pin 32 AT ISS Low Signal (4WD w/MT1)
I’m running neither 4WD nor A/T so it makes sense to me that they’d come out, but the website does not make mention of removing these.
2. How is the OEM GM automatic harness supposed to interface with the T56 manual? Although my T56 came with all sensors, I don’t have any of the “connectors/pigtails” that plug into the T56 since my harness is from an Auto.
3. While at the junkyard, I picked up EV1 connectors that I’ll resolder into the harness to be able to run a car style intake and injectors. No brainer there. While at the junkyard, I also grabbed a dual fan setup out of a 2005ish Monte Carlo (harness included, I clipped it well aft of the pigtails, which are still plugged into the fans. Would controlling the GM Monte Carlo fans with the Van PCM be as easy as adding pinouts into the van harness? Are there already pins there for contolling (what were) the van fans? The stock van fans had to have been controlled somehow.
When are you thinking this thing will start?
I’m shooting for April or more likely May. It’s a bit too early to tell when exactly it’ll be done since there are a million details to button up, but I’m getting there. I got some great feedback on wiring from another guy on bimmerforums who did this swap a year ago, so I’ll be diving into the harness tonight.
I’m here for the Engineering gang bang.
In my opinion the angle of the engine and the drive shaft joints are a moot point almost. Seriously if you’re in the ballpark you’ll be fine, this isn’t a purpose built race car lifting the wheels pushing 1000hp. Look at everyone that lifts or slams cars, they operate ok this has been figured out already. I think people often over engineer things… sweet project! Get 'r done.

Also anyone remember doing super shitty fast swaps and how well they turned out? I’d be interested to see some super cheap budget V8 swaps done as cheaply and quickly as possible. I drove around a truck that had one motor mount. The engine would literally move about 12" if I mashed on the gas. Worked fine for about a year haha.
You will tune out all codes. Secondary O2’s will be removed in the tune so you can pull out those wires if you want to. VATS is tuned out as well. You can get the ECU flashed for a M6 and just not worry about the connectors for the most part.
T56 = Backup lights, CAGS (skip shift) solenoid, VSS, reverse lockout solenoid

:bigtup: jumping on that harness tonight
when i removed the BMW engine the right front motor mount nut was so loose that the crane was able to lift the motor about 3/4" on that side until the mount hit the bottom of the nut.
oh and meant to ask, since this is a local forum, who does local PCM tuning?
I’m looking to do a few things:
Delete:
VATS
2nd O2
CAGS (when/if the PCM has to be enabled to M6 operation)
As well as mild performance tune for:
LS6 intake
42# Ford greentop injectors
317 heads milled to 66cc chambers (still have to calculate what compression ratio this gives me)
Definitely a cool and unique project
Norbert? Damn dude I recognized these from fb! Awesome build thread!
Go to NewEra for any sort of tuning. I highly advise you stay far away from JNJ.
Why did you go with those injectors?
+1 for NewEra
Tunedbyfrost.com minglor had his tune done by him. He’s got a pretty quick turnaround
You need VATS turned off and an injector constant put in there. You can get away with a slighty modded OEM flash
Your pussy still hurt because I wouldn’t illegally roll back the odometer on your leased VW?
I lost $6,600 bucks like a man I didn’t need your illegal shenanigans to do anything for me. Although i do know someones lease you will be rolling back once its up. Truthfully I’d like to spit in your face when I see you.
You can PM me if you’d like instead of cluttering up a good thread.
Norb, messaged you.
There’s a ? for Luke L…
