its in the car and pulls like a mother ****** for a factory motor.
he is willing to let me have the motor/trans/ecu/harness for 2300.(if i help him take it out)
i am curious if there is a difference between the efini motors or not.
the motor is really clean and i can believe its a efini but i am not sure about the braghthurst..
if someone can please enlighten me i would appreciate it..

"Bathurst" info:
http://rotarynews.com/node/view/60
http://www.turborx7.com/efinirx7.htm
http://www.ultimatecarpage.com/frame...hp&carnum=1070
The name Bathurst was chosen to commemorate the Bathurst 12-hour car race in Australia, where the RX-7 has been victorious for three consecutive years (1992 through 1994). Since that time all limited edition versions of the RX-7 have carried the Bathurst name.
Sales of the RX-7 Type R Bathurst R are limited to 500 units for all of Japan.
PS, the 787B was in 2nd place at the LeMans race, with no hope of winning until the 1st place car (Mercedes, I believe) broke.

I'd be inclined to doubt that it's a bathhurst engine- but if it is and you can prove it I imagine some people on the forums might double your money.

what about all the other laps where something went wrong with the 787 or the porsche's,
that's what endurance races are all about, if it's luck, call it what you want, but it happens to every manufacturer. how many porsche carts were there to mazda's?

i agree.. if it breaks in the race.. it should not win.. endurance is key.
but HOW WOULD I FIND OUT IF ITS A BATHHURST ENGINE?
if it is.. i would deffinetly consider sellin it.. but i will need a complete swap too!
AND IF THEY WON IT 3 YEARS IN A ROW HOW IS THAT LUCK?

The 2001 Spirit R Bathurst edition used the same motor as the Spirit R, which used the same engine as the RX-7 RZ. If I had to guess, I'd say that nearly half of the RX-7's produced after 1999 had the 280hp engine. The main differences in the special editions (RZ, Spirit R, Spirit R Bathurst) were the wheels, suspension, and interiors.
With regards to the Australian Bathurst endurance race, the cars that won those were Australia-only RX-7 SP editions. Here's a great website that gives the history of the RX-7 SP: http://www.rx7.net.nz/sp1.htm
This website gives a great RX-7 overview, and includes the SP as well as the US and Japanese models:
http://www.mazda-rx7.info/history/
With regards to Lemans endurance racing, I think the 787 was a great race car, but it would be a lie to say that the rotary made more power than everyone out there just because it didn't have pistons. The rotary is great for racing because it's very compact and relatively lightweight, and can tolerate sustained high-RPM operation.
To be quite honest, there are better ways to get 300hp out of an FD. All you really need is a good ECU, and upgrades to the fuel system, cooling system, downpipe, intercooler, intake, exhaust and a high-flow cat converter (or catless midpipe).

it doesnt have the airbox.. it has a apexi intake kit on it.. however he has a diff sitting on a shelf in good shape he says came out of the same car the engine came from that he is claiming is 4:33 gears.
i dont know how to tell difference.. and i dont know if any of the rx7s came factory with that gearing in the differential. does anybody else know?

There has to be a casting code or something that designates it as a newer motor. Is the motor actually any different in the 99+'s? if the motor isn't any different i'd just look into the turbos and any other different parts.

looking at the specs makes me wonder why they used the engine at all especially at the cosmos last year (1995) considering that the REW was obviously developed before then. *shrug*

The 13b re was designed before the 13b REW was . and it was designed with a heavier sedan in mind.
I think that was the era when mazda wanted more rotary engines in there cars. They did some RandD from the S5 13BT and came with the 13B RE . More refinement and the 13B REW was born.
( RE turbos are ht10 and ht12 and they have the restrictor in the exhaust port , while the 13B REWs have the ht12 twin setup and a freer exhaust ) .

Would you like to drive a Bathurst?
Just a little interesting side note:
I discovered the other day when shopping for my daughter (who loves video games) something interesting to FD owners.
If you would like to test drive a realistic Bathurst, they have one in Gran Turismo 4 for the Playstation 2. I imagiine that the Playstation 3 will have a similar version available if is not already. They have over 700 different cars. I had a lot of fun racing my daughter while behind the driver's seat of a 2001 Bathurst R. Very cool!
