Today I received the 2nd part for the next phase of performance modifications for my car... it came in the form of the Newer Cast version of the Pure 800 Turbo.

My current setup is:
Stage 2+ BM3 93 oct map
XHP Stage 3
VRSF 4.5" Catted Downpipe
TU HPFP
TU Spark Plugs
MST Intake
Masata Chargepipe
Remus Catback Exhaust

As some of you know the Pure 800 has been a popular turbo in many B58 cars, but this newer Cast one is even better with more gains. It has a cast compressor housing along with a cast exhaust manifold, essentially built from the ground up. This turbo also spools up quicker than the older Pure 800. Another positive, there's no core charge with this so you get to keep your stock turbo too.

I bought the turbo directly from Pure Turbos EU. Very happy with the whole buying experience and service from them. I ordered it Wednesday evening and it arrived Friday morning.

Few more bits to get before everything gets done. I already have a 5" Osprey Performance Catted Downpipe waiting to go on. I'm also going to upgrade my coolant lines and coolant tanks to the newer versions that BMW released for the G30.

Looking forward to getting all these bits on and seeing where the build goes.

Please document as much as you can I’m very interested. Pics of the new vs old coolant stuff would be great, I’m not sure what is on my 2019 540. I plan on doing something similar with this car a little down the line but I already have a catless downpipe and stage 2 MHD tune. Will this be your daily driver?

Good luck with the modding.

I'll try my best to capture as much as I can. Might be a little difficult as the work will be done by someone else but I will ask for pictures etc to add to my write up. Yes, this is my daily car (even though I only drive it 2/3 times a week) so will be opting for a safe/more reliable map in regards to tuning. Then maybe something abit more at a later date.

Thank you

why are you switching downpipes and are there any gains with the TU sparkplugs?

My current downpipe is a 4.5" VRSF catted one. Osprey say their 5" catted downpipe flows the same as a 4.5" catless downpipe does... I'm curious about this and wanted to see if it would make a difference to the car.

As for the TU plugs, they were recommended to me for tuned B58 engines. The BMW B58TU spark plugs are the same as NGK 94201(SILZKGR8B8S) spark plugs. I did read that they help with knock resistance and misfire reduction...it's something I've tried and not seen any negatives, so went with a new fresh set. My last set of plugs were fitted at 45,000 miles. The car is at around 56,000 miles now.

Looking to upgrade to the Pure800 turbo in the future. Will be following and please keep us updated on your upgrades and the increase in hp gained. Good luck !

[AntWrig]

I wonder if I should change the following as well...

BMW V2 Coolant Tank
BMW V2 Charge Cooler Tank
BMW Coolant and Charger Cooler Tank Caps
BMW Coolant Tank to Radiator Pipe
BMW Intake Manifold to Charge Cooler Tank Pipe

I am currently awaiting..

IPOS Motorsport IM450 B46/B48 Turbo Upgrade
IPOS B48/B46 Upgraded Intake Manifold
IPOS Motorsport B46 True 4-Inch Catless Downpipe
B58TU/Supra High Pressure Fuel Pump

The car just went above 40k and it's barely driven for a 2018. Since everything will be out, I guess I might as well.

Do you have those part numbers?

Do you have any signs of leaking or any issues? I didn't have any leaks from the tanks but I could see the seam was starting to show signs. The car is currently in the shop having work done, when they removed the coolant pipe it cracked and broke in 2 - so I'm glad I had a new one to go on. I say for piece of mind, get them changed out while you're having the other work done as they will need to drain the coolant anyway.

Some nice upgrade for your car there! I've heard of IPOS - they have some decent stuff on their website.

Part numbers below for all the coolant bits:

17125A02485 - Pipe, Expansion Tank-Radiator

17117639020 - Coolant Expansion Tank Cap

17139846642 - Coolant Expansion Tank

17135A1BD89 - Charge Cooler Tank Cap

17139485733 - Charge Cooler Tank

17128602646 - Pipe, Intake-Charge Cooler Tank

I definitely decided to go a different route, hence taking the B48 to the next level.
The B48 modding scene has finally taken off its amazing seeing the numbers people are putting down.
Anyway, looking forward to seeing where I go. The car already brings a smile to my face every time I drive it.

Thanks for the part numbers!

I'm keen to do this update as well on the cooling side to prevent what sounds like a weak point in the older tanks. Odd thing I noticed with the Expansion tank is that RealOEM seems to list item 17139884859 as the current version. They state it Supersedes:
17139487210(02/01/2018 — 05/29/2019),
17138742975(07/24/2017 — 03/08/2018),
17138610656(07/01/2015 — 01/18/2018)

The part 17139846642 you used wasn't even listed on there. <confused>

When I checked one of the places where I buy my parts, they have it listed - 17139846642 superseeds 17139884859, as well as the other part numbers you listed.

17139884859 shows an 'up to' date of 08/2020

I don't think 17139846642 is on RealOEM as it's a part that comes on the LCI cars (which are not on RealOEM as you know) but the part is still backward compatible with pre-LCI cars.

Ah OK, was wondering if it was a case like that. Cool - cheers
Good to know the part numbers. I'm going to try and order through my local and do the upgrade as part of next service.

Keep us posted in terms of the mighty Pure800 upgrade. The car must be brutal with that on board.

[buddyboy]

I bet your wife can wait to get all those parts out of the house and fitted to the car ��

haha. She's grown immune to them and given up

[darkrom]

I'm super curious with the power on the 5" catted. I know a supra thread out there somewhere has a guy with an upgraded turbo wondering why he didn't make nearly enough power as he expected, and when he went from catted to catless it was a massive difference, not the usual small numbers people quote for a stock turbo car. I've been very skeptical of all the claims that catted vs catless is a small difference on B58, I'm not sure how that could be the case for just this platform specifically.

I guess we can always compare your car to a catless one with similar mods, but the tune and tuner and so many other factors will come into play.

I'm hoping it makes great power because my catless smells so bad right now I'm beginning to think I actually have a leak somewhere in the system.

[Junebug85]

Stage 3 ✅️... after posting and talking about it for a while 😄 the car is now stage 3.

New parts installed:
Pure 800 Cast Hybrid Turbo
Pure Turbos Silicone Turbo Inlet Elbow
Osprey 5" Catted Downpipe
NGK 94201 Spark Plugs

Other parts/work carried out:
BMW v2 Coolant Tank
BMW v2 Charge Cooler Tank
BMW Coolant Pipes
BMW Turbo fitting kit (gaskets and bolts)
Oil Change
Coolant Refresh (with system bleed on both circuits)

The work was carried out by my friend who is a BMW Specialist (RS Automotive). He previously did the stage 2+ setup on my car and has continued to maintain the car too, when it comes to any servicing work.

While I was having the 'Turbo' work done, I saw it as a good opportunity to have the coolant tanks and pipes changed out. Glad I did - as soon as the pipe from radiator to the coolant tank was removed, it broke in 2. You can tell the difeerence between the newer tanks from the older ones as the newer ones don't have the bleed screw/valve on the top near the cap.

The car is now running a custom tune on pump fuel (99Ron) from Velocity Tuning via Bootmod3. I opted to have the car road tuned rather than dyno tuned which did take a little longer (mostly due to the lovely weather we recently had in the UK 🌧🌧&#127783

There is headroom for more so will look at additional fuelling options in the future... as well as a new brake setup as I'm sure that will need doing!

My 540ix has been transformed from great car to an even better one. Power delivery is very smooth and the car just wants to keep pulling more and more. Stage 2+ wasn't slow by any means but it is now a whole lot faster and you can feel it for sure. Even when pushing on you can feel how much better the car is in terms of handling - that's down to the F90 M5 Sway bars and front and rear reinforcements. Very enjoyable to drive, more so than before.

I've not done any accounting numbers yet 😆... (Dyno or Dragy Times) but will do, hopefully at some point

So as it stands, the current engine build is:

Pure 800 Cast Hybrid Turbo
Pure Turbos Silicone Turbo Inlet Elbow
BM3 Custom Tune from Velocity Tuning
XHP Stage 3 TCU Tune
Osprey 5" Catted Downpipe
Osprey V2 Heat Shield
B58TU HPFP
MST Intake Induction Kit
Masata Charge Pipe
Remus Catback Exhaust System
NGK 94201 Spark Plugs

Please keep documenting everything. This is a sick 540!

Those bars in the engine bay idk what to call them, strut braces I guess. Did you notice any difference after installing those? They LOOK really nice in that engine bay.

Please get some dyno numbers! Great work keep it up.

To answer your questions about the brace - the feedback is positive. I've not seen any negative impact having this fitted. The car definetly feels more rigid and a lot sharper when turning in - I guess where the strut bar fits could possibly be one of the reasons why. But I also have a few F90 M5 parts fitted that have changed the way the car handles (sway bars, front and rear braces etc)

If I were to do it again, I would fit the Hardrace brace first and then work my way through the F90 braces and reinforcements and try to see what difference each part adds. I like to think that with all these parts added, they are now all contributing to the way the car handles and drives.

I set out with the aim of improving the handling and drivability of the car and I think I've been able to do so, to a certian level. I'm not seeing or feeling any negative or worse impact of all this. Steering is more sharper and tight and like I mentioned before, you can actually feel the increased rigidity when going round bends. There is a stiffer feel and the floaty like feeling has almost gone. Even my wife noticed that there was a change for the better and she only drives the car a few times a month.

I've also had fast road geo alignment done on the car which helps with all this too.

Thank you! I haven't got the car on a dyno, something I need to get round to sorting.

The car is running great and no issues since having the Turbo and other bits fitted. Since then, I have installed a Ross Racing PCV Breather Kit (v2) and a RR Oil Catch Can. This was just as a preventative measure to try and bulletproof one of the B58 engine flaws.

Car is still running on 99RON Pump Fuel at the moment. I have started to look at additional fuelling options to maybe run upto E30. Just looking and researching what route to potentially take with it... The way the car is now, it's not needed - but it's more of a nice to have
