Anyone know who would carry low pressure power steering hoses in bmw sizes, just tried CarQuest, O'Reilly, Napa, AutoZone and only found 1/2"

Update - used http://www.autohausaz.com/pn/32411095526 as it fits perfect from the res to m60 hardline going to the power steering pump. Trim it to fit .

For the steering rack to res I found 1/2" transmission/power steering hose sold by the foot and used that.

Of course it wouldn't be my typical day if I didn't run into some issue. I ordered a replacement m6x 740i oil filter housing filter support element, and it doesn't fit. The one in my oil filter housing is threaded on the bottom, and it seems the only ones I can find to order are SNAP-IN with o-ring on the bottom ?!

Sigh. Looks like I am not the only one who ran into this - http://www.m5board.com/vbulletin/e39...r-problem.html still trying to figure out solution....

holy crap jean! this is one of the best and most concise engine swap threads i have seen here. good on you for posting your trials and tribulations. this will be so helpful to those that follow you in the future.

why no abs? i see you have an early 318 car. i assume it did not come installed from the factory? i am really happy to see the filter housing bracket worked for you.

do you plan to run air conditioning?

also....sub'd

Haha thanks man ! I know this swap isn't new, and crap I was supposed to have this one done 3 years ago but life got in the way and I had to pause it .

So yeah , lots of folks since then have completed this swap but there were certain areas that I thought I could improve on for serviceability and in some areas for aesthetics.

The car in question didn't come with abs from the factory and I never felt there was a reason to retrofit one , I've driven it through rain and California winter with both m10 and m30 engines and never had an issue as long as tires were good and you pay attention.

Now, ac was removed many ages ago and sometimes I wish I kept the hard lines in the engine ...I may add ac back in the car but what I have in mind will be also different from what people have done with this swap . The passenger side frame rail clearance does not allow for compressor to fit without cutting into the frame rail a couple of inches , that's something I am not willing to do . My plan is to utilize the stock mounting points for the passenger side bracket / engine arm and get a custom bracket fabricated to bring the compressor closer to the engine and also utilize a smallest compressor I can find to fit in there . Who knows maybe this won't even work, but that's an idea that I'll follow and see how successful it will be.

And looks like I've found out more about the oil filter housing support bracket , there was a service action by bmw to update the support bracket in order to allow for "more environmentally friendly oil filters "

I haven't seen anyone report this issue here yet , perhaps no one has tried replacing that part with a new part and then discover this issue :/

Update:

-got the power steering system/lines all finished up today.



The only thing I don't like about the power steering setup is it seems the return line from E30 res down to the pipe seems just a HAIR too lose to my liking, using a brand new hose and it fits the RES side perfect but the bottom isn't as tight.

Starting to wonder if there is a difference in PS res between e30 (what I am using) and e46 for example ...or perhaps there is not e46 rack banjo end fitting I can find with slightly BIGGER diameter to fit the hose perfect. The banjo end fitting on the lower pressure side would need to match the diameter of the plastic RES side.


-got oil filter housing lines/return line finished today
-oil filter housing oil bracket re-installed, learned that you can't order the center plastic support bracket that goes inside the 96+ housings, that's the screw-in part vs the plastic tower that snaps in in the earlier cars.
- removed spark plugs, put a little bit of oil in each cylinder, rotated the engine a few rotations to make sure nothing was binding and just wanted to get some lubrication in each cylinder
- torqued new plugs in place
- checked each ignition could with DMM , then re-installed in place
- traced the fuel return and charcoal canister lines
- test fitted smaller oil filter in the back of the car near the external fuel pump
- got the e36 lower radiator hose, don't like how it fits , it rubs against the oil dipstick tube too much, this is the GATES 22440 hose. This hose can actually be used for the UPPER radiator hose though.
- got the gates 20923 for the upper radiator hose, shortened it and it fits perfect as the UPPER radiator hose.
- got another gates 18965 long straight hose with the molded end on one side that fits PERFECT on the 325e expansion tank, and the other end fits perfect as well on the 740i pump side for expansion tank...hose is long enough to use w/o any splicing. This is the hose I used (shortened) for one of my rear heat hoses, the molded side is perfect size for the rear water accumulator side and the other end is perfect size for the hard lines for the heater hose connections,.

- test fitted stock 540i/740i lower radiator hose 11 53 1 741 407 and it clears the oil dipstick tube obviously much better than the e36 hose. I may try to use this hose instead.

- tried re-installing new 540i throttle cable and for some reason no matter what position I try on the firewall side I can't get the throttle body to close fully even when the adjuster own the cable is maxed out. I may end up modifying the throttle cable metal bracket instead. Not sure why I am running into this issue, using the cable everyone recommends, bracket appears to be stock 540i and isn't bent or damaged ...cable is new, gas pedal linkage has been shortened to clear the wilwood pedals .

- got two DME's ready for the swap, both are manual 404 black label non EWS versions.
One with manual stock 530i m60 chip with b40 maps from DUMD, and second one is a virgin 404 black 540i/6speed manual chip as backup.
Got a stock 404 auto as well, just in case so I can compare these run and read (code wise).

- my old 15x8 tire rack e30 specific wheels reinstalled with new Kumho V720 225/45 tires (wish I waited and new about the new 15x9 and 245 options out now :./

- Starting to trace wires for the harness.

TO DO list is finally getting smaller :)

- figure out the throttle cable situation
- install new throttle linkage bushings

- run new wires for the check engine light and speed sensor
- run extra wires for future to add additional sensors (oil temp, oil pressure, etc)
- run battery cable to the trunk and install battery box
- re-install dash / interior

- get the lower radiator hose option figured out
- get expansion tank mounted and hose connected

- install starter
- get manifolds modified and installed
- get the stock b40 y-pipes modified and installed
- get walker cats installed order correct o2 sensors to match the wiring harness

Can I get a picture??? This part will work for me i think with another extension piece.

The long straight gates hose is pretty expensive at local shops, so order it on eBay or Amazon it's almost half price there.

Here you go buddy! Tomorrow I'll get a new 540i lower hose and see how well I can get it to fit e30 chassis/z3m rad..as it fits much better than the e36 lower hose due it's perfect angle that goes around the m60 oil dipstick tube.

[Jean]

Got a couple more things done today -

- expansion tank mounted, I tried 3 different combination of tanks (e30 late model, e30 early model, and the e32/e34 tank that sits at the firewall) and picked the one I liked the most from aesthetics and serviceability.
- coolant hoses routed / test fitted
- fuel filter installed (used half of another external fuel pump bracket as a fuel filter holder)
- replaced some old fuel lines
- installed new throttle/gas pedal bushings (highly recommend doing this)
- test fitted hood to make sure clearance is good (ended up lowering the clutch/brake red about half an inch)
- tried both e36 lower radiator hose and e34 540i hose, went with 540i hose as it simply fits better after cutting about 1/2" from both ends and it doesn't rub against the oil dipstick tube (e36 325i hose does not have the needed curvature)









Need to get some heat reflective material/tubing to wrap the soft fuel lines in the engine bay and also power steering res lines.
Also will probably shorten the res lines and make a small holder/bracket to keep them close to firewall and away from back of the engine.

[delamaize]

Let us know how the power steering works out. I want to add it back to mine, but I'm lost on where to start. I have the stock M60 540i pump and a E46 330i rack.

Sure, you need to get a custom high pressure line made by someone who does these or transmission lines . Should cost you under $100 total .

The other two lines are low pressure , use half the hard line from the m60 pump as it routes up the engine bay past the alternator and exhaust and from there run a soft line to res, and another line from res down to the rack .

Do i see... ACTUAL CRIMP HOSE CLAMPS FOR FUEL LINES?!?!

I wish i could be as proper as you

[Jean]

Hahaha! They are so damn nice !

[Jean]

More progress made today, interior is starting to look like a car again and not a mess of parts.

I had an issue with the modified throttle bracket, I modified it per instructions (shortened to clear the wilwood pedal box) and then I noticed I couldn't get the throttle body to fully open at WOT ... my theory was that the shortened throttle bracket changed the ratio and accelerator cable was not able to have as much movement for throttle body to fully open from a closed position. I've confirmed my theory was correct, and it had nothing to do with the throttle cable adjuster position on the bracket. I ended up getting another pedal bracket and shortened it just enough to clear the wilwood pedal assembly but trying to keep the lever end as long as possible. This fixed the issue for good, new bushings installed and also went ahead added a factory spring to the gas pedal.

I didn't like how the pedal felt without the spring on the bracket and only relying on the throttle body spring, it felt "lazy" and just didn't feel right. There was a stud on the firewall that I attached a small bracket to and a stock spring to that.

First modified pedal bracket (too short, not enough reach for the accelerator cable to have enough reach to open the TB to WOT from fully closed position) vs. current.





Need to remove the bracket for stock brake switch, as I am using a remote bracket switch in the engine bay. Ran the wires to that, picked up some nice loom for it so it would look nice and clean. Fished some extra 4pin wire near fusebox for check engine light and speed sensor wiring. And also ran an extra 4pin wire in the loom for future, I may want to add oil temp/pressure gauges,.



Started working on moving the battery to the trunk, of course my car does not even have a cutout for the positive wire so I had to cut one. Need to pull carpet on the passenger side and run the factory positive terminal wire to the trunk.

TO DO list



Not sure what I am going to do with the SPAL fan, it appears that I can fit it in the engine bay as a puller vs as a pusher. I'd much rather run a puller than a pusher as this way I can make a more effective fan shroud VS. running a pusher infront of the rad. The SPAL fan that I have will fit in the engine bay if I offset it to a side on the passenger side, this way it won't interfere with the crank pulley or anything else from a quick test fit.

Still need think about this, and I have another idea in mind as well but need to sleep on it.
