BigBoost Turbo about to release B58 turbo upgrade and Port Injection!

Hi all,

Last week we got our own M240i for parts development. After doing some baseline runs at the dyno, we finally got to work on it. Our plans are manufacturing a stage 3 turbo and a port-injection, both to be released by late May. Stages 1 and 2 with direct replacement turbocharger will follow, no estimate time of arrival for those.

It Fits both RHD and LHD vehicles! :)
We'll keep you updated on progress!
*Update*
We got the manifold yesterday and will be testing the kit with just JB4, EWG Wires and Meth injection, while PI is being manufactured.

Awesome, can't wait for updates

The B58 engine is a stout mill that is going to be with us for quite a bit as it represents BMW's new modular engine design. As far as tuning is concerned, it responds well to bolt on modifications but there is a fuel cap in the ECU designed to keep owners from taking it too far.

Well, good luck with that BMW. BigBoost Turbo is readying a port fuel injection system which should provide the B58 with all the fuel it needs to run their upgraded turbocharger.

You can get an idea as to how much bigger their turbo is than the factory unit in the pictures provided.

It is very early in the B58 tuning game so it is good to see turbo vendors tackling it.

Ok guys,

So today we have machined the manifold that arrived yesterday from the foundry. We have test fitted it and looks great, we took some pictures to share with you. Port injection is now on CAD design, we hope one month from today we will start some testing.

This is the Stage 1 or which turbo setup? How do the stages differ exactly?

This is stage 3,

Stage 1 will just change the compressor for a larger 7 blade billet wheel in the stock cartridge
Stage 2 will be larger turbine and compressor wheels.
Stage 3 is complete new manifold with complete turbo, downpipe, inlet pipe and chargepipe.

What is the turbo?

This is huge. Nobody has a big turbo B58 upgrade.

That's going to be VERY nice.

Looking forward to the testing results from the various Stages.

For sure we will post results! At least for stage 3 now.

What will control the port injection, jb4?

Yes, JB4 integrated PI controller

Here's the baseline for the car:

stage 3: $3750, giving pre-order at $3199
Stage 2: $1750 + core
Stage 1: $1150 + core

^ wow, great pricing as well. Looking forward to seeing where the B58 will go. Great job so far guys!

Port Injection almost ready! :D:)

Some more records coming soon!

Bump for those that didn't see this.

dyno ?

Correct me if Im wrong but if you didn't jack up the motor mount or removed too much from the engine bay the B58 looks like there is alot of room to swap turbos compared to the N55.

Anyways good work man!

A lot more! I take about 8 hours to install a kit on N55, B58 is only 4 hours!

What are the mods on this run?

Lol this makes me so jelly! I wish my m2 had the b58 lol. The only reason why I currently, importance is the key emphasis on currently, prefer the n55 is because it's an older motor so development is finally happening on it so there are abundance of parts now coming to the market. Also because it's race proven (correct me if I'm wrong) on the m235ir unlike the s55 or B58 (safety cars don't count imo). Personally I'd probably like to have a B58 for the sole reason that it seems so much easier to work on, not so much about it being better closing the deck can be done after market and a turbo is easily upgraded imo.

On the M2 it is a proven race engine as the oil pan and pick up system is made for high G's on cornering, as well as the M235R (same oil pan as S55) However a regular N55 does not have that oil pan and secondary pick up and suffers from oil starvation on the track. The B58 looks very promising and looks like it has potential for racing. I have gone to track days on our M240i and it definitely moves! The oil pan design on the B58 is good for the track and looks like the oil starvation problem is solved on this.

yup another reason why i went m2! I love this car and am looking to equip it in the future with your stage 3 kit or speedtech!

Because we are committed with our customers we have a fully developed wastegated exhaust manifold which allows full boost control without compromising performance!

The reason we developed this new manifold was because some cars varying on weather conditions and additional hardware were building boost very fast while the DME wasn't fast enough to control the boost correctly, causing throttle oscillations. The external wastegate keeps the twin scroll division so the awesome response these cars were having is kept but allowing full top end performance without throttle closures.

All these tests were done on 93 octane fuel and throttle body injection.

Mods: Stage 3 turbo with wastegated manifold and manual boost controller, Throttle Body Injection with #24 jet, Jb4, BMS intake. Stock catback exhaust. V.8 firmware

Here there are different maps and settings, dyno and log.

Most graphs have the boost which is named as user analog 1.

Attachments were broken. My apologies. Fixed now. I'll clean up the big boost post for them if they want.

attachments still not working
