Speedtech releases N54 cast manifold single turbo kit - 810 whp

[Sticky]

Speedtech is known on BimmerBoost for their N55 turbo kit but now they are releasing an N54 single turbo conversion. The N54 single turbo kit market sure is crowded and increasingly so each passing day but Speedtech seems to bringing some big guns to the mix.

First, their demo car is a 2010 BMW 335i running a Borg Warner SX-E 364 (8776) turbocharger.

An 810 whp dynograph at 29 psi definitely will get attention although keep in mind Dynocoms read high:

What are some of the kit specs?

Manifold/downpipe/dumppipe arrangement advantages:

• Efficient flowpath with consistent boost control
• Keeps wastegate cold-side in cool air for reliability and easy spring changes
• Places O2 sensors in ideal location to keep sensor body temps down to prolong life and allow easy access for service.
• Fewest joints and welds for leak free, trouble free operation
• Provides ample clearance from all hot-side components
• Allows use of stock motor mount isolator

Cast manifold:

Similar to our N55 manifold, we designed the N54 manifold to not sacrifice on anything. Maximum bend radii, flow simulation, stress analysis, thermal cycling analysis… This manifold design takes an OEM approach to making huge power.

There are plenty of turbo options to choose from:

• BorgWarner
  
  • SX-E 252, 257, 362, 363, 364
  
  
• Garrett
  
  • G, GT, GTW, GTX 3076, 3576, 3582, 3584, 4088
  
  
• Precision
  
  • 5558, 5858, 5862, 6062, 6262, 6266, 6466, 6766, 6870, 6875, 7275

The pricing is aggressive:

We'll see how the N54 community responds to this offering but it is yet another option to consider.
