Montaje del Motor Renesis - Mazda RX-8 - NO REBUILD
Proceso de remontaje del motor Renesis de un Mazda RX-8. NO ES UN REBUILD
de Motor puesto que no se han cambiado ninguna junta de estanqueidad,
sellos de aceite o sellos de motor. Se ha limpiado todas las piezas y se
han reutilizado, con el propósito de practicar el montaje del motor y
almacenarlo de una manera mas compacta para en un futuro rehacerlo con
piezas destinadas a su uso en competición.
REPITO: NO REBUILD, el motor no funcionará puesto que no tiene juntas de
estanqueidad, es un video de propósito meramente instructivo.

Rotary 20B turbo RX7 - Dyno & track
Built as an all-round event's car, Charles' Mazda RX-7 has undergone
serious chassis and engine changes including a Promaz Automotive
bridge-port 20B rotary engine. Boost
comes from a Garrett turbocharger while
the engine runs on methanol fuel controlled by a MicroTech LT16 computer
and LTC dash logger. Backed by a Jerico 5-speed dogbox, the clutch was
suffering on the Dyno
as the Promaz team got the car ready for Performance Car Mania. [

20B rotary RX-7 Spirit R: The Ultimate Street Mazda
Built by Promaz Automotive, we think it's hard to go past Steve's wicked
Series 8 FD RX-7 if rotaries are your game. Limited to around 1500 unit's,
the Spirit R was the last of the RX-7's and featured a lot of upgraded
factory parts as well as a low 1100kg weight.
Now powered by a lethal Promaz triple rotor 20B extend port rotary engine,
power is aided by a Garrett GT42R turbo
and MicroTech fuel system and transmitted through an Albins 5-speed gearbox
and KAAZ rear end [ http://www.promaz.com.au ].
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
4-rotor. It is the first 4-rotor since the 787b to use triple spark plugs
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
custom Peripheral Port in each rotor housing (defined auto), Aluminum side
housings for reduced weight. Needle roller bearing in the center housing.
