If you have updated info (preferably verifiable by pic of time slip or quote from magazine etc) let me know and I'll add it.


Here is a collection of what to the best of my knowledge are the world's fastest rotaries in the following categories:
*Quickest overall 1/4 Mile
*Highest Speed
*Quickest 1/4 mile for a "full bodied" car
*Quickest 1/4 mile for a "Legally Registered" car.


Quickest 12A in the world

The world's quickest 12A rotary over the 1/4 mile is this almost certainly this car.

Owned by Boris from Delirium Racing in Puerto Rico, this Datsun 1200 is powered by a 12A turbo. It's best time is 8.27 @ 160 mph!
This is quite an achievement as there are many 13B and 20B powered cars that are 2 or 3 seconds slower than this.

Here's what Boris said about the car (minor edit by me):
The car is a 1972 Datsun 1200 full tube mild steel chassis. It has the 12A with an Innovative turbo and wastegate, a Tial blowoff valve a Greddy intercooler with 4 1100cc injectors. The throttle body is custom made and has a Racing Beat intake. It runs the stock distributor with MSD 6AL boxes and coils. The fuel injection system is a Haltech F-9 programmed by Jorge "Oso" Juarbe. The engine has a port job done by Jose Burgos.
We use VP Race fuel with a Aeromotive fuel pump and regulator. We use a Mc Leod clutch with a G-Force 5 speed clutchless tranny. This hooks up to a 9" Ford rearend with 4.56 gears. The tires used are 29X12 Goodyear slicks.
Other members on the Delirium race team are Ismael Velazquez, the pitman and my wife Astrid Lopez who also helps out. Any other questions contact me at

Thanks to Rabule and Carlos from for sending me the photos.

This rail dragster is said to be the world's fastest 1/4 mile rotary, at 8.03 seconds/167MPH, using a 650hp supercharged 20B and weighing 650kg.

Highest top speed

Almost without doubt the racing beat Bonneville racer with it's 900+ hp triple turbo 13G engine is the world's fastest rotary car, at 242 MPH (387 km/h)

Until the appearance of the rail dragster at the top of this page, the world's quickest 1/4 mile rotary was this car, "Rafaelito", with a 510 bhp 13B turbo, using a Weber carburettor and weighing 770kg (1700 lb), it does 8.45 seconds/160mph
(Update - 14 May 1998 from Rafael in Puerto Rico, This car is down to 8.19 seconds)
(Update - 30 August 1998 from Vicente, Reyberto & Jose in Puerto Rico, This car is down to 8.07 seconds at 170mph. Thanks also to Vicente for the most recent pictures at the lower half of the pics above)
(Update - 25 November 1998 7.87/171mph , Thanks to Vicente of Cayey Racing Team, in Puerto Rico)

This is quite probably one of the world's quickest street registered rotary cars.

Owned by Rene from California, USA this RX3 is powered by a GSL-SE 13B with aftermarket turbo (for the uninitiated the GSL-SE was the highest spec 1st gen RX7 1st generation RX7 is 1979-1985 model (in Aus the series 1/2/3) with fuel injected 13B derived from the RX5 The RX5 sold in Aus/UK was known as the Cosmo in the USA.
This engine was different to the 13B used in the 2nd gen RX7 2nd generation RX7 is 1986-1991 model (in Aus the series 4/5). Given that the car does 8.8 @ 160mph and is the original steel bodywork I would guess this car is making in the 700hp+ region which is interesting given the basic engine was around 135hp.

Here's what Rene said about the car (minor edit by me):
Hi there, my name is Rene and I am sending you this little story about my drag Mazda Rx3.
This car may be one of the fastest all steel street registered Mazda RX-3s around. My car is non tubbed, all original with windows, original suspension except for the rear end and tranny, but it is street registered with only 26x8.5x15inch rear slicks running a record setting 8.80@160mph, 3000 ft above sea level in December 2001. I only have a 85gsle SE street port turbo set-up no NOS, running fuel injection. I have been looking at your website for a long time and I am interested in getting my little story out there if possible. Here are some pics of my car when I did my record setting time. Check out the registered license plate. thanks

<Craig note - I asked if the time was in street trim - i.e. with tyres as used on the street. response was:>

No the car was on full slicks when I did these times at the track but I change tyres for the street. Slicks are 26x8.5x15. Here are some more pictures of my car I dug out and some time slips. Check out some of the 60ft on this car, even today I get surprised about the 60ft

Perhaps this is the world's quickest rotary over the 1/4 mile that is "Legally Registered".. Yes this car is in fact "legally" allowed to drive on the road! (though I suspect the police would throw the book at you if you tried!).
It has a 550hp 13B turbo and does 9.41/145mph
(Update - 17 November 1997, this car has done 9.36/142mph)
(Update - 16 June 1998, 9.05/ ? mph)
(Update - 23 June 1998, 8.78/154mph)
n.b. This section was originally added in 1997 and I have since been told by several people that it was never actually streetable.

Most Powerful 13B?

Japanese Specifications (640x480)
Specifications (in Japanese) (640x480)

This FD3S (3rd generation) RX7 is made by a company called Esprit.
It is powered by a 13B-REW engine which the modifiers claim makes 700ps (ps is 'metric horsepower', and is measured differently - probably about 650 SAE horsepower).

Turbo: Single T78 @ 1.5 kg/cm (21 PSI boost)
Muffler: Stock
Computer: Stock
Injectors: Six 550cc and Six 440cc

It also features a lot of HKS equipment such as boost controller, auxiliary fuel computer.
It is a pricey conversion at over $US 10k as you could build a 20B for the same price.
The car is on page 49 of the Japanese book 'Hyper-rev RX7 FC3S & FD3S', published in 1992 in Japan. This book is available from time to time in Japan and is a Japanese RX7 fan's bible. Unfortunately it is virtually impossible to get outside Japan.

There is another 13B of comparable power made by a company called 'Scoot'. It uses a peripheral port and single turbo.
Pictures captured from a video that's on the web. There's 3 guys sitting on the back of the car to try and help traction on the dyno!
(Update Dec 2002 - the esprit RX7 was made in 1992, 10 years ago at time of writing. this was leading edge at the time at it took until about 1999 before I heard of others making 600-700hp 13B-REW engines with mostly stock internals, I have heard reports of 740, even 800hp from a 13B-REW on nitrous. It would be feasible to set up the intake ports, turbo and fuel systems for 900hp although this is really in exploding engine territory)

Most Outrageous car?

20B Clubman engine (640x480)

20B powered clubman (640x240)
400HP 20B clubman

This 20B powered car is perhaps the world's wildest rotary. Perhaps not the best overall handling, top speed or accelerating, but a 400hp 20B in a sub-1000kg (Probably about 700kg) would be pretty hard to match. Unfortunately there are no more details available.
See links below for another similar car.

While not quite in the world's fastest category, this car is still very fast and I've included it for the spectacular picture; it is doing a big launch (the car bent the panel at the front when it hit the ground) at a 1998 street meet in Adelaide, Australia.
The car now has wheelie bars fitted but has not done a pass with them yet. The owner hopes to beat their personal best of 10.22 @137 mph.
Also note the blue flame roaring out of the wastegate near the front right hand side wheel.
This car was built by Tim from RPM rotary in Adelaide

... I also wanted to let you know that unfortunately, for Rafaleito Racing, there is a new BEAST in Puerto Rico, I am talking about Siguel Racing's new 20B powered RX-7. This thing is wild, and from what I've read in the local magazines, it is already in the low 7's, 7.37 @ 180 MPH to be exact. It was published in Super Compacto magazine August-September 2001 issue, but unfortunately I'm not quite sure if this ET is official. just wanted to keep you informed, hopefully you won't take this in a wrong manner, but raher informative. Thank you for your time.
