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

[Juan@BigBoost-Billet]

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.

[Juan@BigBoost-Billet]

What is the turbo?

61.0 mm compressor
59.0 mm turbine

61.0 mm compressor
59.0 mm turbine

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.

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!

This is 4th and 5th gear

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