Handbuilt 4-Rotor Engine
This was a project that took about five years of weekends to put together.
There was a lot of trial and error as jury-rigged parts were improvised and
revised, leaks were identified and plugged, and byzantine electrical
diagrams were decoded. It still does not run smoothly, as there likely is
a problem with the intake system that has prevented smooth timing at idle.
But she runs!
lots of people wanted to know where the E-shaft came from: it was custom
ordered from a shop in New Zealand.

Mazda RX-7 Spitting Huge Flames from Exhaust!
When I was driving back from an event, this turbocharged Mazda RX-7 FD3S passed me in a
tunnel. As you can see this tuned Mazda RX-7 FD3S was spitting some huge
flames from the Exhaust! Hate it or
love it, I really enjoyed it! :)

Sapore di Super - Motore Wankel e Mazda Rx-7
Molti di voi sicuramente non sanno cos'è il motore Wankel. Alcuni di voi
ne avranno sentito parlare. Questo video è destinato sicuramente ai primi
ma anche ai secondi, perché una cosa è averne sentito parlare o essersi
documentati con libri o sul web, tutt'altra cosa è vederne uno aperto. Il
Wankel-devoto Diego Gisti ce ne illustra passo passo il funzionamento
ruotando a mano l'albero motore di una unità Mazda 13B, per poi procedere
alla dissezione dei singoli organi e alla descrizione degli stessi. Il
video si conclude con alcune immagini della sua Mazda RX-7 che tra breve
verrà rimessa su strada con il suo bel Wankel rimesso a nuovo - Sapore di

Mazda Rx7 4-rotor race car. The making of a Defined Autoworks Beast. [Offical Video]
Never before seen footage showing the assembly/start-up of our custom

per rotor. It is also the first since the 787 to feature telescoping intake
manifold. Custom made slide throttle body system. A world first however is
the use of a center main bearing and 4-piece eccentric shaft. Quick specs-
9.7:1 rotors, lightened and race clearanced. Race main bearings, and race
rotor bearings, ceramic NRS 2mm apex seals. Custom stationary gears, Full
