the GSR option from bimmerworld is definitely the best option out there. I've seen documented cases where the oil pump nut is secured with a wire or loctite and when it's time to blow, instead of the nut breaking off, the entire shaft breaks. there are also a few people on this forum who have used the VAC option and, because of staying in the upper rpm band a lot, have found the unit to still fail.

Hobbits input on this: "I don't think it's the power, it's the rpm combined with the harmonics of the 3.0 crank. The Rally Road Oil Pump Nut should be fine for under 7100rpm"

So it sounds like everyone says the failure is caused by vibration from the crank, but that vibration really only becomes a problem at higher RPMs... The upgrade makes sense on a track car where you are hitting high RPMs constantly, but on a street car where you rarely are in the high RPMs it sounds like the oil pump will manage with just a secured nut.

Im undecided on the matter... I know i will never track my car but seeing all the horror stories scares me

Just Another M54 Turbo Build. By the People, for the People

Yeah I'm going GSR for peace of mind. Good points from all around, however since I'm in there already to install the turbo oil drain I figure I might as well. Also using a S54 timing chain tensioner.

But for example, I don't think the ati damper is worth it, as you can buy a used motor for the price of the unit...

Put the GSR oil pump on the engine.

The ATI damper is not necessary for a street engine.


A stock M54B30 starts to nose over at 5900 RPM. Adding boost hides this a little bit, but the pumping efficiency of the engine still goes down above 6000 RPM by a lot. Focus on making power under 6000 RPM, and you should be fine.

As an odd side note, I recently grenaded an alternator spinning an M54B30 over 7000 RPM. It looks like the cooling fins on the stator flew apart taking out the coil assembly. I'm not sure if it was a vibration issue due to the bearings, or some sort of damage/failure of the fins, but a 15+ year old alternator probably needs to be looked at. (Or replaced) In my case, I have packaged so much stuff around the alternator, that removing it was a huge PITA. I had to remove the crank case breather, oil cooler lines, charge pipe, power steering reservoir and bracket, power steering pump and bracket, and put the car 2 feet in the air to get at stuff from the bottom. In retrospect, I should have just ordered a new one when building the engine...

think about it this way...you already have to take the oil pan out (which isn't technically difficult but can be time consuming) to secure the oil pump nut. so while you're already in there, why not just take the extra step and install the GSR unit? then you've got it and never have to look back because it'll always be there.

if the stock nut comes off for whatever reason, then you're stuck pulling the oil pan all over again to fix something that could've been fixed the first time around. in the big scheme of things for a full turbo build, I don't think $400 for a quality part that will also give you peace of mind is too out of the question.

Just Another M54 Turbo Build. By the People, for the People

Installed stage 2 today.

I have never had a crank pulley/harmonic balancer that was so easy to slide off the crank and reinstall. I usually have to wrestle with a puller but this was a breeze with a cheap three claw puller and little effort to get it going. I just grabbed around the outside edge. The only issue was I used the starter motor to loosen the crank bolt. I placed the breaker bar against the ground and turned over the motor break the super tight bolt. The breaker bar rebounded and took out a chunk of the brake duct. Ouch. But not a big deal, and I will be replacing this soon to accommodate a new bumper anyway. Be careful if you ever try this.

On a side note my old harmonic balancer was toast. The rubber was totally distorted and coming out of the front groove. Wish I changed this a while ago and hope it hasn't been this way for too long. My engine has 125k on it. I'll post pics of it tomorrow.

The CSF radiator makes the fan a super close fit to the pulleys. It also takes some ingenuity to mount correctly as obviously their jig isn't perfect, but wasn't a big deal. I used new pulleys and belts with this install as well.

The turbo cooling hose adapter is right below the vanos, currently plugged, but will be easy to access when I install the turbo.

I also installed a S54 timing chain tensioner that I purchased used. Didn't notice any difference but I didn't expect too, just for peace of mind.

Anybody have any exhaust/muffler/resonator suggestions or diy kits you like? My friend welds really well so I was thinking of fabbing it up instead of having a shop do it. I don't want it to be too loud though.

Why not build a y-pipe to connect to the stock exhaust?

Keep in mind the turbo will "muffle" the sound also. When I helped a friend recently with his turbo E46, we used a 3 inch stainless setup, one cat, one straight through unbaffled muffler, and the sound isnt over the top, it is just awesome

As a side note, we did install some V band joins in case it was too loud. At least this way it was easy to add ot take out components to fine tune the setup

I am going to run some straight through Magnaflow bullet mufflers on 3" all the way back.



The manifold and downpipe came in and all looks well.

However, my turbo outlet is a 3" 4 bolt design, while my DP inlet is a 2.5" 4 bolt. So I am left with 3 choices...

1) Have a custom 3" DP fabricated using the current 2.5" as a "model". Upside- Max performance. Downside- Expensive and chances are it will end up not fitting for some weird reason.

2) Run this turbine housing- http://www.atpturbo.com/mm5/merchant...Category_Code=
Upside- All my stuff will fit...I hope. Downside- 250$ and how much power am I losing from a 2.5" outlet?

3) Have the end of my 2.5" DP lopped off and a 3" flange welded on. Upside- Cheap. Downside- I feel like there will be weird effects, like turbo lag, from the hot expanding gasses coming out of a 3" outlet, into a 2.5" pipe, and then back into a 3" pipe. I am not running a lot of boost, does this even matter or will it not effect me much? I wanr to keep my driveability ok.

I have been reading and cant find a stright answer if going 3" is needed or will hurt the way the car drives. I also read a smaller DP will help torque and spool speed? Lots of bench racing and conflicting info on the web...

Also here is the harmonic balancer, you can see the rubber all squirmy and coming out of the front of the groove it sits in.

Also I think I may have a custom 3" DP welded up. I don't want to do this twice so might as well.

Also the PMAS HPX maf came in. I suggest you buy their complete kit on ebay, it comes with the housing and PIG-VI wire for much less than their online store.

The pinout if the maf is as follows

Hobbit, THE man, let me know to "Wire the signal to the yellow wire in the harness, the power goes to the red and white. Sensor ground goes to the black, and then the other ground goes to chassis ground. I used the oil dip stick bolt because it's close. The iat wires can be left alone."

The housing is also much too long so I am going to drop it off at a shop, which will likely be doing my DP in 3" as well, this week to be cut and a bead welded around the outside edges for hose connections to stay solid against.

Thermal efficiency seems to be my theme as of late so I also took some time to cover my charge pipes with some gold heat tape to hopefully keep the intake air just a little bit lower.

Also I am selling my Wavetrac lsd, included is the unit with a 3.07 ring gear attached to it, new bearings and races from diffsonline. The pumpkin is not included. This wavetrac is for the 3.07 and 2.93 gear size pumpkins. It has about 500 miles on it. Brand new bearings with 0 miles. Works great, 950 shipped. Use your own gear from your stock diff and this makes a nice drop in unit ready to go. Will post pics when I remove it from the pumpkin(had issue with pinion bearing).

Just met with a cool garage and coordinated welding up the exhaust. Am going to run one vibrant ultra quiet resonator and a magnaflow rear race muffler.

Also am going to control boost through the ecu via hobbits method and run a innovate lc-2 wideband AFR gauge.

It's looking like it's going to be installed the first weekend of May! Can't wait

The cx manifold causes some issues with ac and there's almost nothing you can do.
I am almost done with my 330 and the ac came out within the first 2 days. I tried to bend the lines out of the way and they crimped and busted. The ac compressor didnt clear the manifold on my car, so I had to take it out.
There are a few ports on the back of the manifold with rubber plugs that I connected the bov and map sensor for my scg 1 to.
If you have any questions about your build, I'm in the middle of mine right now so everything is still fresh in my mind. I might be able to answer some questions that you have
