HR Tri-Loaf FD3S (20B 3 Rotor FD RX-7)

HR Tri-Loaf FD3S (20B 3 Rotor FD RX-7)

Tri-Rotor 3rd Gen FD RX-7

Phase 1 Is complete.
Look for phase 2-5 to be completed soon.

Tri-Loaf, what is that? At HR, the term "loaf" engine is slang for the rotary motor. It's derived from the design & it's assembly/building process. The housings (& internals) are stacked together like a loaf of bread. Tri is a given, for the # Three. (3 rotor) Giving birth to the HR Tri-Loaf FD3S.

Starting with a 100% bone stock FD, Himni Racing Has Set New Standards & criterias for what a street driven 20B 3 rotor FD3S RX-7 should be. We have taken all the normal & conventional 20B to FD3S conversion methods, used by other shops & thrown them in the trash. HR steps up & raises the bar yet again, producing an extreme, well rounded & balanced street converted 20B FD3S. Staying true to HR form, the attention to detail is second to non!

** The HR Tri-Loaf FD uses a 100% factory front sub-frame, steering rack, & spindles to insure that the car will still perform as it should. No modifications or relocations were made to these parts. The engine sits clean & as low as possible. The weight was moved around intelligently to achieve strong a strong layout. The car is loaded with many one-off, HR hand made parts from the SS turbo exhaust manifold, to monster sized fuel rails, 4" exhaust, mounts, etc. There is a lot of secret work done to this car. Much off it was to carefully move the power band around to make it as potent as possible. The work & efforts paid off for sure on a grand scale!

This is another Himni Racing on-going project. The car will always be changing & upgrading so keep stopping by to all the new changes & completed build phases. We aren't even close to done with it yet!
