The “Don’t Tell My Wife” Engine Package™ 🤫
You're looking at
@mikevanesch’s complete front subframe assembly.
This engine made 480 hp last year on a Garrett G25-550. The turbo has now been upgraded to the Gen II G25-585, paired with a custom 3D-printed turbo manifold designed by Mike himself.
The new setup addresses the sealing issues we had with the previous manifold, while the switch from a T25 flange to a 2,5" V-band gives us a significant increase in cross-sectional area, less back pressure and more turbine housing options. Together with the upcoming cams there should be some more power to be found.
Removing the complete assembly made a lot of sense here. With the tightly packed low mount turbo setup, it gave me the space to make sure everything could be routed properly and fit exactly how we wanted.
I designed a custom turbo brace to support the weight of the turbo, with the oil return integrated through the brace.
The manifold was welded by
@fb_awt and machined flat and Cerakoted in-house, all lines have been rerouted, and the 3" downpipe clears the
@spsmotorsport BMW gearbox conversion nicely.
The compressor housing was prepared for custom aluminum intercooler piping and more clearance at the steering rack. More on this soon.
This was a hell of a lot of work to make everything fit absolutely mint, but the end result was well worth it.
The
@supermiata Xidas aren't looking too bad in there either. 👀
