Clutch line and ABS relocation.

This week I worked on the clutch line. Since my car was an automatic I had to weld on a bracket to hold the adapter at the end of the hard line. SInce I was welding it on I decided to try angle it so that it would best fit my set up. I also cut the factory T56 clutch line down and attached a -4 end on it. I've attached a picture. Don't mind the scribbled "clutch" on the chassis. I'm not sure how i managed to write upside down like that at all. I'm a little concerend on how easy it will be to install the line with the headers on. I'll guess I'll find out later.

After modifing the clutch line I pulled the engine ando finished mounting the ABS in it's new location. I need to adjust some of the lines for better fit but the mounting is done. Now that the engine is out I'll finish the fuel and lines and work on the heater lines. For the heater lines I'm looking at making the bulk of it out of Hardline. I'll see how it turns out.

Wiring and fuel

After some more delays due to having to repair my tractorys Hydroic pump and also a computer hard drive crash taking my time I was finally able to get back to working on the car. Unfortunately most of the work is wiring. It was surprising how much time the wiring has taken. Not very difficult but time consuming and not very exciting to talk about. However I believe I have it done. All the wires are connected to where they should go. I need to re-loom the harness but other than that it is finished.

This saturday I started on the fuel lines. I looked at numerous ways to connect up the fuel lines and settled on using aluminum hard lines. The aluminum line can easily be cut and then beaded to have the ridge to keep the rubber hose from slipping off. They were also easy to form and smaller in overall dia than braided lines. I mounted the filter/pressure regulator (corvette part#) under the car. To do the kind of job I wanted I removed the driver seat and drilled a hole through the floor to bolt the pressure regulator. Then I welded a nut on the inside of the car to make removal of the pressure regulator possible without removing the seat. I probably could have used a sheet metal screw to do the same thing but I wanted something a little stronger.

From the pressure regulator back I used aftermarket quick connects then rubber hose and then to hardline. 3/8 aluminum for the supply and the factory 5/16 for the return. While I was at it I replaced the section of supply line that crossed above the tank with 3/8 aluminum line.

The portion of the fuel line from the regulator to the engine I have roughly layed out but I'm going to wait until I have the engine out to make the final shape and securely mount it. It'll be much easier that way. Oh also this weekend I installed the new P/S pulley to replace the one that was broken during shipment.

For now I need to turn my attention to heater hoses and the clutch line. The to do list is getting shorter.

Wiring and More Wiring

After a delay due to vacation I was able to get some more done. This week I mounted the PCM into the pocket in the firewall where the BMW had the DME and trans computer located. I did this by modifying the BMW computer bracket and the GM computer bracket and attaching them together. I only had to trim the pocket opening slightly to get the PCM to slide into it's new home.

With the PCM located I began the work on integrating the GM wiring into the BMW. I spent hours and hours reading the BMW and LS1 wiring diagrams. After a lot of thought I decided to utilize all the BMW fuses and relays. I did make a few changes to make the wiring fit a little better. I took the BMW O2 relay and used it for the A/C relay. I then used the A/C relay and used it for the 3rd Fan relay. This reduced the # of wires going through the main connector from the engine wire harness. I also found that very few of the engine systems for the BMW actually had replaceable fuses (protected only by the main fuseable link) I am not satisfied with this and will be adding 5 additional fuses to protect the main power circuits feeding the motor systems.

Also done this week was to fabricate a shifter adapter to move the shift lever forward about 40mm. This moves the shift lever to center of the BMW shifter location.

The First Test fit of the engine

I was heading out of town for the week so not much was going to happen on this project for sometime. I decided it'd be fun to have the engine sitting in the car while I was gone. so thursday evening I loaded it in. It's a tight fit but it's in there. I didn't have the driverside header on but I do have it bolted to the engine and trans mounts and to the car. I also test fit the driveshaft I have and it fit perfect. Lots to do yet but it is looking like it is going to work out.

Installing the clutch and brake pedal

The pedal set from a manual BMW was given to me as a christmas present (my car was originally an automatic). I finally installed the clutch and brake pedal into the car this week. The nice thing about installing it was that the bracket that holds the pedals was the same for both the manual and the auto so I just had to transfer the pedals and the master clutch cyl to the car. Sometimes I don't know what BMW was thinking when they desiged some parts of the car. The clutch mater cyl inside the car and not in the engine bay?? Installing the pedals sounded pretty easy but installing the helper return spring proved to be challenging. I finally got it. I found the bracket to hold the other end of the clutch hard line is not on the car and it appears that the electrical connector for the clutch switch is not on the car either. Small stuff but it still has to be done. It would have been nicer to have a manual trans car to start with



.

Power Steering Pressure line

Also done this weekend was the Power Steering pressure line. This I thought turned out really well. It was my first time making a custom powersteering line. Starting at the Power steering pump then working to the rack the part#'s are as follows.

1. Saginaw P/S Metric Conv Adapter (FBM2608)

2. -6 90 Deg Hose End, PS (FBM1389)

3. -6 AQP Pwr Steering Hose (FBG0600 aprx 1.5 feet)

4. -6 45 Deg Hose end, PS (FBM1386)

5. Male 14 x 1.5mm Metric Concave Seat to 6AN, Steel (3276-004)

6. 14mm Crush washer (I reused the one from the steering rack)

Part#5 I had a hard time finding in steel. I did find it at Pegasus. All the other parts were from Hoerr Racing.

Also done this weekend was to put the fireproof sleeve over the steering shaft. Aeroquip fireproof sleeve 1.5" dia was used. Purchased from Pegasus under part#3299-1.50 (aprox 15" worth) I also routed the wiring for the starter between the starter and the block to be farther from the header heat. Then wraped the whole starter in Heat Barrier (Thermo Tec Aluminized Heat barrier). Oh while I'm spitting out part#'s of things I've used. For the oil pressure switch I used a M16x1.5 to 1/8-27 NPT adapter (Equus part# 9848) and a pressure switch from Napa part#0p6613SB They said it was from a typical chevy product and was about $2.00.

Other things done this weekend were to begin the relocation process for the ABS unit, installing the clutch and brake pedal set (the car was an automatic) and relocating the heater valves. These haven't yet been completed.

Clutch remote bleed line

Finally the last fitting I needed to complete my remote bleed line showed up on the 14th. After weeks of being on back order I finally recieved the fitting. In the picture is shown the parts.

The parts starting at the slave cyl are.

1. 10mm crush washer (Pegasus part# 3241-3/8)

2. -4 to 10mmx1.5 metric adapter (Aeroquip FCM2967 or Goodridge 305-04-35P)

3. 36" of -4 teflong brake line with Straight/Straight Swivel fitting ends (BL-6104-36)

4. Female 10x1.0mm Metric concave seat to -4 Steel (pegasus part# 3265-19)

5. 10mmx1 bleed screw (bought at NAPA).

Part 4 and 5 could have been any thread that matched and not 10mmx1.0 but fitting 4 is the same fitting that could be used for adapting the BMW clutch hardline to -4 AN. I thought it would be best to make them the same. The parts that are not pegasus (http://www.pegasusautoracing.com/) or NAPA were purchased at Hoerr Racing (http://www.hrpworld.com/). I was unable to find part 2 and 4 at the same place. Oh well.

After installing the engine to the car I found 36" of line is probably too long but it all depends on where you plan put the end of the bleed line.

BMW engine removal

Well I'm not very good at keeping things updated. Last weekend I pulled the BMW motor. All and all it went fairly well and wasn't too difficult. One of the features I like on the BMW is the fact the hood will open nearly vertical. No real need to remove the hood. Also everything infront of the radiator unbolts so the motor can be pulled basically straight forward.

In the picture is the LS1 waiting to go in and the BMW motor hanging on the hoist. I spent the remainder of the week checking out the wiring and labeling the wires.

This weeks update

This week I finalized decisions on the fuel lines. I decided to go with the GM quick connects after all. I cut one out of the end of the loose fuel line on the engine to use on the fuel filter/pressure regulator. I also bought a tool from the local autoparts store to disconnect the GM quick connect lines. In demonstrating how the connectors work to my wife I connected the fitting to the fuel filter and then disconnected it with the tool. Or rather I tried to disconnect it with the tool. The tool (which is made exclusively for removing these type of connectors) would not fit between the filter and the top of the fitting so it could not be slide into the fitting to disconnect it. Have I mentioned how I hate these quick connect fittings?

I also ordered some more pieces to complete the Clutch line and clutch bleedline. While I was at it I found a steel version of a powersteering fitting adapter I needed (I had previously only found aluminum ones). So I ordered that too. I'll list all the part #'s and descriptions AFTER I verify it all fits.

I did sell some of the LS1 parts I didn't need this week. The unmodified oil pan, The Camaro pedal assy, the trans cross member and the catylitic converter. However, about the only actual work to the engine I did this week was to fabricate the driver side motor mount heat sheild.

Slow going.

Not much happened this last week. With the holiday weekend and going out of town there wasn't much time. I did manage to order a few things. I ordered most of what is needed to make the clutch line, remote bleed line for the clutch, Powersteering pressure line, and The heat shielding for the starter. Also collecte the fuel filter/pressure regulator (bought it at NAPA and they had to order it from their warehouse). Local parts store thought it was the most interesting thing ever. Guess they'd never seen one or sold one before now. Bad part is that some of the parts for the clutch lines were out of stock so it will probably be another week before I see the parts. Waiting for parts is the part of the project I hate. Good thing I am ordering parts now.

I still have to decide exactly how I'll connect the fuel lines. I really hate the GM quick disconnect lines. They seem really awkward and how quick do I need to remove the fuel lines anyway?

Motor mounts finished

Well it looks like daily posts aren't going to happen. Maybe I'll try for weekly. Anyway....
Didn't get much done this weekend as I had other things to attend to. However, I finished up the motor mounts. I welded on end caps and painted them. I've now been looking at making some heat shield for the motor mounts just to make sure they don't get too hot. I've also been researching and deciding on a few misc items that I need to buy.

I received the ECU back from being reprogrammed, VATS, skipshift, rear o2 sensor removed and the factory tune tweaked. I used the company http://www.wait4meperformance.com/ The price was good and they got the ECU back to me quickly. I currently have no way to test it to see if anything was done or not. For now it goes back on the shelf waiting to be installed.

Engine mounts

Yesterday I re-made the engine mounts. I replaced the solid steel mounts with some polyurethane mounts. More specifically ENS-3-1114G

Custom oil pan install and headers test fit.

OK. Been busy working on the project and doing research so I haven't done much posting.

Last week I mapped out the the engine wire harness.



Saturday I removed the stock oil pan and installed the custom made pan I have. To install the custom made pan required some trimming of the windage tray.





Last night I test fit the custom long tube headers on the engine. The LH header required a boss to be ground down to fit. 2 of The header pipes on the LH side fit very close to the block.

Look What Followed Me Home

My engine and arrived to day [4/25/2007]. I thought it would be funny to use the BMW to pick it up from the terminal instead of my pathfinder. (I put the hitch on for hauling canoes and bikes). The engine is from a 2002 Camaro SS 6 speed MT with 18,000 miles on it. I am glad to see after about 2 years of research and planning the project is starting to look serious.

Oh in the one pict you can see the custom headers for the project hanging on the Garage wall.

I plan to pull the existing BMW motor sometime in June or July. I'm still using the car to cart my kids to school. I'll wait until their school gets out then I'll switch back to driving my RX-7, powered by a Nissan V-6, while I work on the BMW.

Until then, I will spend my time collecting a few more parts I need, I'll figure out where all the wires go, send the PCM off for reprogramming and test assemble a few things to the motor. I am hoping to get a lot prepared so once swap begins it will go reasonably quickly.

Buy Conversion Parts

While still looking for the right LS1 engine the project made progress by buying a big box of parts from John Carps LS1-E36 that crashed. I'm hoping this will speed up my project. However I may remake the motor mounts as they are solid steel and I'd prefer something with some compliance since I'm building a street car.

Purchased items include:

• Exhaust
  
• Radiator
  
• Trans and engine mounts
  
• Misc Parts

Realizing I needed the modified oil pan that John had sold with the engine I contacted the buyer of the engine and offered to buy the pan. Since the engine was going into a Rx-7 conversion the pan was sold to me for just a little more than a used oil pan + shipping. What a deal.
While continuing my search for an LS1 engine and information on LS1's I found an add for headders for a LS1 BMW swap. Turns out they were the headers from John's car and they were up forsale for a good price. With a little luck I was able to grab those as well.

Some of the parts spent months hanging on the garage wall.

Fixing it up.

One of the first thing done was to sort out an electrical problem that didn't power the front windows when the key was on and the doors closed. Then to pass safety inspection the RH side mirror, 2 rear tires and a worn ball joint were replaced. The mechanical fan had broken and had been removed by the previous owner so I installed an electric fan. Figured I could use that after the motor was swapped out too.

The smell was removed from the car. The bulk of the smell was coming from a tar like substance in the trunk. Looked like something was spilled that was absorbed into the sound deadening material in the trunk. I also repaired the power locks and a number of other small items. When looking under the car one day I noticed one of the rear lower control arms was bent. Looked as though it had been that way for quite some time. So 2 new lower control arms were installed.

I figured the best way to find all the gremlins would be to drive the car. It did run and drive after all so why not. Can't drive without music so I replaced the head unit with an Alpine something. It had iPod controls thats what I cared about. Oh and added an iPod. I also installed 6 1/2 in mid bass speakers in the kick panel. Yes cutting is required but they fit behind the factory trim so no one would know. I also installed some after-market tweeters in the factory tweeter holes and a 10" sub and amp was mounted behind the the rear seat.

With school starting (I drop my kids off at school on the way to work) the BMW was pressed into service. All and all the car was pretty nice to drive. The inside looked pretty worn though so I replaced the worn stock seats with some nice looking leather E46 sport seats I bought of e-bay. Oh yah they are heated too. I've enjoyed that. Now my kids want a heated back seat too. Maybe someday.


After driving the BMW awhile one day the end of the thermostat hosing broke off. I've read Bimmerforums that this was common. However when I took the thermostat housing off I found that the end had indeed been broken off then GLUED BACK ON! What the.... An aluminum thermostat housing doesn't cost very much. Why would anyone glue the broken housing back together. An aluminum housing was installed with new gaskets and new thermostat. Car went back to the road again.

Step 1 - Aquire a BMW

Step #1 in doing an engine swap on a BMW was to acquire a BMW 3 series. This sounded easy but living in RURAL Virginia there aren't too many E36's near by to choose from. I watched for about a year for one to be reasonably close to me for a decent price. After barely missing out on what was probably the pefect car only 40 miles away I became frustrated and was about to give up on the idea. Instead I bought a car sight unseen of e-bay for $1600 just to get the project started. The car was 1993 BMW 325i with 200,000 miles and in need of some help.

I had never asked the mileage on the car or if it ran prior to me buying it. The owners excitedly showed me that it ran when I went to pick it up. Sadly the way it ran was probably the best feature of the car. Closer inspection showed that the car must have been run thu a wire fence leaving it with scratches on both sides and small dents in the doors on both sides. It was also missing one side mirror.
The leather seats were cracked from age.

What can't be seen in the photos is how the car smelled... Since the car did run i thought I'd try to drive it the 1.5 hours back home. In less than a 1/4 mile I was pushing all the window buttons trying to get the windows down with no luck. I was thinking if I can't get the windows down I'll tow it because it just due to the smell. I turned the fan on full blast and stopped at the first gas station. As I filled the car I found the windows only went down with a door open. Odd. Have to look at that later. But hey it ran and driveing it was more fun then towing it.

About halfway home the car attracted the attention of a local police officer who noticed it didn't have plates. He suggested that we should put it on the dolly and tow it home. Well.....it was more like put it on the dolly or it isn't leaving. Hey, Not a problem. That's why I brought the dolly in the first place....see it's on. Ok? He didn't write me any tickets so it's all good. I climbed up in my old Pathfinder, the same pathfinder that towed my Rx-7 project home (another story). And to my surprise it towed the BMW easily. Even through the blue ridge mountains.

All in all we made it home safe. And hey. Even with the worn shocks and a short drive I could tell this was going to be a fun car to drive.
