E39 Touring 6speed Build

Going with M60 down pipes is the way to go, I'm planning to go that route in the spring.

I’ve decided to cut the pre cats out and added a vband clamp to the factory header.

Last week I replaced my old android for a avinusa 10.25 android and it fits the interior nicely


Friday night I pulled the motor out, didn’t feel like removing the front end and removing the ac/ps so I was able to pull it up without the trans



Today I took the transmission and all the under covers home to clean and reseal the transmission




Few more seals and I will be dropping the motor in.

Then all I have to do is figure out the easiest way to reset the self adjusting clutch.

Looks really go, was there a reason you didn't opt for the M60 exhaust manifolds.

I have the M60 exhaust manifolds and the Y pipe from the S62, but not sure if it's the right setup.

I hope you mean M60 style and actually have M62 manifolds.
The pipe stagger at the collector is flipped between m60-62 .
I have both but haven't bothered to check if the amount of stagger is the same between them, which would allow you to cut the mid pipe at the first curve in and flip them side to side.

No one locally is parting out a pre face 540i, as I would need the headers and the mid section.

And I didn’t feel like waiting or buying a set off a wrecker for 2x it’s value.

Most likely M62 non tu headers as m60 wouldn’t clear steering box unless it’s not a E39

When the border opens, pm me.
Also the biggest hassle is lengthening the O2 sensor leads to the rearward position.
Not just wire, but shielded wire.
Having done the swap, not sure there's much benefit. The tu manifold flows well. Ditch the pre cat, although I'm not saying cats hurt performance.

Thank for sharing that information. I need to get it out my head that going without preCat provides big HP returns.
I recall removing Cats on my Toyota Cressida fitted with Supra JZ engine and transmission.

I actually cut the cuts right up the o2 sensors, and will be welding a vband flange there.


I also cut the post cats and dudmd codes out my rear cats

Been busy this week trying to get the motor ready to get dropped in before the New Years.

Welded up the vbands on the stock headers



Got the motor all assembled, had to swap the front driver timing cover as the one on the new motor had stripped threads for the vc




When pulling the timing cover found the issue with the old motor.


After I messed with the motor, I started to replace all the heater hoses, replaced the power steering lines and all new crush washers, and installed a front eibach swaybar.



While having some sun this week cleaned the engine bay.


Before I put the motor in decided to work on the sc mount as it seems to be slight off


Hopefully next update motors in.

In my experience, the pre-cat exh manifolds on the M62tu Tourings are definitely restrictive. In comparison to swapping in the M62/S62 exh manis on the M62tu I cannot say, as I haven't done that swap. But I can confirm that there's power to be gained by replacing the M62tu pre cats manifolds with long tube headers. In my case I installed the Supersprint headers. The gains documented with these SS headers in the S62 world is between 20-30 WHP, and this is going from the already better flowing M62/S62 exh manis -> SS headers might I add. If you're boosted in my and in karies case, freer (sp?) flowing exh manifolds can only be of greater benefit. No......I didn't dyno my car after installing the SS headers, but the gains (aka butt dyno feel) associated with the S62 isn't that far off on the M62tu, based on the 30+ years I've been modifying cars with performance parts. Take it as you will, just my experience + just my $0.00002 cents.

It would be interesting to see if there are worthy gains to be had by just removing the pre-cats and keeping the M62tu exh manis like karies did. Regardless, I think we can agree that it can only be a positive in terms of performance. Hopefully he'll be able to go back to the dyno one day and give us some data. Keep up the great work karies, I always look forward to reading the updates on your build!

Yeah stock catted headers i think would be very restrictive, inlet to the cats are 2.75" and the outlet of the cats are 2.5 then into a dual walled 2.5" mid section to a Y and 2.25" inlet to the resonator.

the car will be going back on the dyno and well be able to see the gains without the cats as that will be the only difference in the setup, im predicting 20whp gains my tuner thinks it will be alot more so we will see.

thanks whiteghost1!!

Got the motor and transmission all buttoned up!



Just missing fluids and finish up some wiring clean up.

Also installed a slimbones front lip and it makes it look better I think.



Going to start it this weekend and start building the exhaust next week.

Welp this week was an interesting one.

Built my mid section with 2.5” piping, but I will be cutting it to add a flange to make the Center section removable.


After this was all done went to bleed the cooling and found a huge leak coming from the new URo valley pan. So got a replacement today and swapped it out.

While bleeding the cooling the cam sensors seems to be failing and code is coming and going, injector 3/4 don’t seem to be working also for some odd reason has almost no run time.

I’ll be looking into this before dynoing and after putting some mileage on the fresh motor.

But overall I took the car around the block and wow big difference without the cats! But now to see what the actual gains are.




Once I get back on the dyno I will post the gains without the cats.

URO valley pan? Nooo! Those are known to not be great and fail prematurely. I use genuine valley pans only...

[coolpersob]

Damn that car is clean. The paint matched door moldings make it look sharp. Wheel fitment on point.

They’re pretty good, I’ve used 5 and this is the first time I’ve had a failure. Atleast it’s pretty easy popping the intake after you’ve done it a million times lol

Interesting! I've only heard bad stories about anything URO. Good to know someone has good experience with them.

I didn’t say all uro parts hahaha, just their valley pan is probably the best option. Other uro parts aren’t great

I was nervous to install the URO jack pad I purchsed but I think its still good. At least its still attached to the car...

Car is now running but im having some issues which is delaying me from driving it home.

i keep getting ENGINE FAILSAFE PROG and a code of 67/103- control unit monitoring, which im having a hard time trying to find info on. So i have a bunch of good spare parts which i thought might help but its not. replaced TB with a known working one nothing, Replaced Pedal with a working one same issue. ive also tried to reset the DME adaptations and its not changing anything.

as for drivability i can get a few blocks before the error and i just re-cycle the key an its back to normal, its like the throttle is opening and closing while im driving.

so this coming week im going to bring the car home and out of the shop and remove the ECUMASTER DET3 and see if it will run with a stock DME, if that doesnt help i will try another DME with EWS deleted and possible swap in a new wiring harness i have sitting around to see if it will make a difference.

Now i have a big oil leak! lol i think the new rear main seal is leaking so im going to pull the trans at home and double check before i make my FCP order.

[karies]

So bit of an update, car is not dialed and tuned.

Plugged in the laptop and erased the timing off the det3 and car ran mint.

So we strapped it on the dyno and cleaned up the tune. I’m pretty happy with the outcome considering it’s only making 4psi.



The end result 332whp



I have some videos but for some odd reason can’t seem to post them on here. But I did add it on my IG: @arise88

Next few days I will be putting the car back together and figure a location for my wideband.
