After many months of R&D we have a “deep breath”

Billet L5P Twisted T4 Pedestal with 45mm Wastegate Provision Prototype

After utilizing Fabricated pedestals in our L5P S400 kits and seeing failures we decided to design a more robust and bulletproof version

This is a prototype piece and will end up in a big fuel/big air non gated setup to push the limits of billet steel. The following run of pedestals will have much cleaner machining as we learnt from this piece. The best part, we partnered with a shop in Alberta to help us with this pedestal, nothing overseas here

Key features-

-Billet CNC Machined from a 140lb block of steel

-45mm Wastegate Provision

-Fully Divided Design with clean interior flow paths

-1” T4 & Up pipe flanges

-1/2” Steel Base plate

-Includes Multi-layer T4 Gasket and A286 Superalloy Stud kit

-M10x1.5 Up Pipe bolt threads are available at request

Wastegate Fitment

-BSI 45mm

-Summit 45mm Pro

-TurboSmart 45mm Hypergate

One step closer to pushing the L5P platform and one step closer to finalizing our L5P S400 kits. These pedestals will be included with every FKF S400 kit moving forward🤘

This pedestal is available on our website with a longer lead time. As we build stock this lead time will drop

Installed one of our 2019-2023 High mount 2G swaps on this 2021. Re coated his intake horn at the same time in Dirty Magic

A 2011 came in for more of a custom kit with a stainless Hoodstack and polished tip. We also re coated some of the parts in his engine bay to match (LP Blue)
