www.3rotor.com - FC RX7 Build

1989 Mazda FC RX7

In February 2005 I managed to pick up this 1989 Series 5 RX7.

My plan is to build a Bridge Port 3rotor with injection and install it.

Standby for updates as they happen.

UPDATE: March 2005

The 13B engine has been removed and work has started on
the engine bay de-loom.

UPDATE: May 2005

The rotors have been ligntened and balanced, I decided to use
S5 6 port NA rotors, high compression and light to start with.

You can see the meat cut out of the rotors.

Just about to start porting the sideplates.

UPDATE: November 2005

The inlet manifold is being made now for the NA 3rotor.
You can see the custom flywheel and new clutch also.

The bottom shots show the dummy block mounted and the
headers that have been made also.

We decided to go electric water pump and a nice
big custom radiator. We also decided to run an electric
power steering pump to try and keep the block as
bear as possible

UPDATE: December 2005

Here is the engine being built. We used this engine for
shooting of the DIY-RE 20B build video.

The 20B engine uses ceramic apex seals, is ported
and uses external oiling.

You can see the triple throttle bodies and exhaust headers.

UPDATE: January 2006

Here are some shots of some of the parts that have come back
from HPC ceramic coating.

I decided to get the engine bay repainted also.

We have now mounted the engine permanently.

UPDATE: August 2006

OK well a lot has happened over the last 6 months.

We have almost finished the RX7, we have fitted coil-over
suspension and new 18" wheels.

The engine bay is finished and we fired it up the other night.
Wow. 20B Bridge Port. Awesome.

UPDATE: September 2006

Here we go. Check out these videos of the FC 20B RX7.
AWESOME.

UPDATE: September 2006

FC RX7 goes on the dyno.
Today we tuned the car on the dyno. Man it sounds awesome
It makes power up to 9000 rpm, pretty scary since it has only
traveled about 50kms and isn't run in yet.
But we made it through the dyno unharmed and managed
300hp at the wheels. Not bad for a non turbo engine.
