For sale:
Unique Ex PP Turbo single 13B rotor sport sedan engine block



Item Condition:
Excellent condition except for Reasonable PP Rotor housing

Extra Info:
Was used in a Mk1 Escort and made aroun 280hp at the engine built in the mid 1990s
until owner went to the wrong engine a heavy Cleveland big bore after blowing the
clutch at 11,500rpm and damaging the firewall and some of the tunnel.
I have sourced machined R5 side endplates untouched port wise as original turbo PP
setup endplate, dowels & rotor were misplaced. The PP rotor housing is still there with
higher inductioin position to suit better timing for boost.
Have all bearings, counterweights just missing rotor which was a stock Rx5 one,
sump and needs new seals. Perfect E-shaft all oiled and wrapped up.
Also cast iron custom brazed single turbo manifold to suit 12at made custom from 12at
exhaust manifold. Front timing cover with all internals for pump, bearing and other bits
even spare set of dowels to suit but need shortening pretty much just needs Rotor,
custom sump and your choice of induction, turbo and port/assemble it to your needs.
Will weigh about 47Kg all complete and can make 120hp NA or 220hp Turbo at the wheels. 

Can also be used as an ultralite engine, trike, motorbike custom or lightweight turbo 1000,
mazda 800, lotus 7 replica or deadly lawnmower

Very interesting and most intriguing! I wish I had enough coin to make the purchase.

I'm completely bemused. I have never gone near a rotary. Would definitely give this a go if I had the spare cash. Interesting stuff. Hope the sale goes to someone who will put it together and use it.

Depending on wether you source parts from ebay
 
eg.
new seals
 
mazda, forums, auto-one, repco or rotary workshop it can cost from 500 to 1500 to finish this rebuilt single rotor all depending on your choice of hp, using the following video which there are many available on cd.  
The most tedious bit is machining the new side seals but if you get a second hand rotor then they can be re-used and avoid the tedious machining of new side seal but having said that its halve the amount of work as show below. 
 
Rotary rebuild instructions 
 
Thats the good part of building a single rotor in that it requires almost halve of parts of a rotary build so in this case it needs a rotor and rotor housing along with the required seal kits, depending on your rotor of choice if low comp for turbo or high comp for NA. 
Best to buy a second hand rotary block which ususally sell cheap when a rotor housing is not usuable the use the good one. The rotor housings are the expensive units now to buy new but if you dont buy a complete short block, you can always buy good second hand ones anywhere from 150-300 dollars each depending on who and what they want for it.
I was going turbo so I could make around 220hp with with LPG as rotaries and LPG are matched perfectly but using a high comp rotor from the latest Renesis engine and Single 2 inch Su with reace extend porting can make around 140hp at 9000 rpm.
 
The R5 rx5 endplates Im supplying just need to be extend ported or used as is for turbo. Essentially the smaller 2 inlet port on the centre plate are deleted in this build meaning the 2 larger outer inlets are kept and supply more air stock copared to a twin rotor. 
It all depends on your intended hp but turbo would cost about the same as extend porting it whether you wish to run it in LPG or a Single SU in drawthrough form or race extend form with single SU Y style manifold.
There is also the choice of going rx8 inlet ports which support 140hp NA as the endhousing front and rear plates have massive ports compared to the centre plate which is not used eg. low kms RX8 endhousing on ebay: rx8 front and matching rx8 rear plate

I can also supply a compact oil cooler and oil filter housing that usually feeds a twin rotor and will more than adequately cool a single with turbo or without. The gearboxes I recommend are the earlier light S1 to S3 smooth case as even some peeps have just started experiencing issues from their S1 boxes after many years spirited driving and some abuse from 200hp extend port 12a engines. 
I could also be interested in a part swap for a turbo manifold you are making if that helps.

In 1996 I rode an NSU in Japan with full extend port 500cc single rotor and revved it to 16,000rpm and made around 138hp according to the engine dyno it was tuned on it is owned by one of my good friends who wouldnt sell me his 1967 cosmos that ended up full of rust due to been left outside along with all his other rare rotary treasures.
 
The RE5 suzuki had a short stroke for a rotor so was able to rev very high while the 13b has more stroke and still able to rev to 11,000rpm with ease compared to a twin rotor due to the e-shaft not suffering the flex of two rotors. There are counts of lawnmower racing revving them to 13,000rpm in single form. 
 
I guess with boost 8-9000rpm should be enough kick in the pants 
 
Do you have any spares for an early 13b rx4 rx5 etc. eg. rotor housing and rotor?

Mr.Teves,
 
Thanks for the kind offer. I have too many engines on the go simultaeneously, will have to give this one a miss. Interesting little unit though.

I am interested in some pictures if i could please?

Link of pics as requested PMd
take note most of the parts where partly glad wrapped
and oiled so a little dusty in some places but all good.
Just forgot the engine dowels and studs but they are
also part of the deal and have other spare dowels etc.
