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

Parts to be Installed:

• Pure Turbos Pure800 Cast Turbo
• Pure Turbos Silicone Turbo Elbow

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 !

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.

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.
