This page is dedicated to BMW Mod Guides. Guides range from 500+hp N54 bolt-ons, N54 port injection, S55 turbo guides, B58 downpipes, and plenty more. Check out all of the awesome BMW turbo engine performance content.
BMW’s N20 engine comes from the factory with respectable power and performance. However, enthusiasts often look to simple bolt-on mods for impressive power gains. An upgraded downpipe is one of the best bolt-on mods for the N20. Removing the restrictive catalytic converter from the downpipe helps unleash the N20’s true potential. In this guide, we…
The two predecessors to the B58, the N54 and N55, were notorious for busting chargepipes left and right. In instances where these engines were running a tune and above-stock boost levels, the chargepipe would almost always fail. One of the main reasons these chargepipes failed is that they were made out of plastic. The chargepipe…
An often overlooked performance upgrade on the BMW N55 engine is the cooling system. When you’re focused on horsepower, it doesn’t seem too appealing to spend $500 on a “mod” that doesn’t really produce meaning performance gains. However, an N55 upgraded intercooler (FMIC) is one of the best modifications for tuned N55s. Rather than being…
Upgraded intakes are our first mod recommendation for people just getting into modding their BMW’s, but also for people looking to push crazy horsepower. An upgraded intake is the building block to further modification as it provides the engine with the additional air capacity needed for high-horsepower applications. Additionally, it’s a great bang-for-the-buck mod if…
The BMW B48 engine is a stout motor from the factory. However, many look to bolt-on parts to take the B48 to the next level. Towards the top of the list lies an upgraded B48 downpipe. Remove the restrictive particulate filter from the downpipe to unleash the B48’s true potential. In this guide, we will…
An upgraded intake is one of the best bang-for-the-buck mods you can get on your B48 turbo engine. Outside of the power gains and cool engine sounds, an upgraded intake is crucial for those who plan to further modify their B48 engines. We always recommend an upgraded intake as the first mod to make on the…
We believe upgraded front mount intercoolers (FMIC’s) are one of the most under-rated mods for the BMW N20. Peak power gains may appear underwhelming for the cost of an upgraded FMIC. However, upgraded intercoolers are excellent on tuned and modded N20 engines. In this guide, we will discuss the many benefits of running an upgraded…
When it comes to exhaust systems on turbocharged vehicles, specifically BMW turbo vehicles, everyone talks about the downpipe instead of the traditional cat-back system that people are most familiar with upgrading. That’s because cat-back exhaust systems and expensive and don’t really provide any power benefit. They sound great, but we’re bargain performance guys here! The…
Yes, the B58 engine does have an intercooler. However, it is not the common intercooler setup you would see on most turbo vehicles. While most forced induction engines use “direct” air-to-air cooling, the B58 intercooler uses an “indirect” water-to-air cooling system. The B58 intercooler is integrated into the intake manifold. Compressed air flows through the…
The exhaust downpipe is the first part of the exhaust system on the N55 engine. It bolts-up straight to the turbocharger and passes air from the turbo to the cat-back portion of the full exhaust system. The OEM downpipes have catalytic converters on them, for emissions purposes. However, the catalytic converters are extremely restrictive and…
A lot of people cringe at the idea of a “cold-air” intake. Theory has it that a cold air intake has a bigger filter which lets in more particles which kills your engine life quicker. And that they don’t offer that much of a performance benefit. The first part about engine lifespan is blah blah….
The BMW S63tu is a 4.4L twin turbo V8 found in 2012-2017 M5 and M6 models. It produces an astounding 560hp and 500 lb-ft of torque from the factory. Even better, like many BMW engines, the S63 is also underrated. Aftermarket dyno tests show the S63 around 530whp and 520wtq. Nor does it end there….
