New project,20b short block renesis in FD RX7

[dthebuk]

so has this 20b been made from 1 and a half renesis engines?
i take it u cant buy the 20b\'s there putting in the concept cars yet

Hallo,
A nice surprise to see this being done! But the designation shouldn\'t be 20B, though as they are very diffrent. Are you using RX8 stationary gears as the centrel bearing support?
 
Thnks

Hi RH,
Strictly you are right yes speaking it is not a production 20b with the larger center plate but the capacity is the same as a 20b. We call it is short block 20b for ease of understanding.We are using a modified FD RX7 stationary gear and bearing for the center plate.

Mazda did make a longer 20b 3 rotor engine that was in a car called the Cosmo,it was made from 1991 to 1996.
The engine we have done is built from all renesis parts,but the eccentric shaft is custom built two piece.

I thought the renesis was all aliminium?  Looks interesting :cool

Renesis is a mix of Cast Iron and aluminium the same as every other rotary that Mazda have made with the exception of the Cosmo 110s that had aluminium side plates.( Circa 1967-1972)

Yes it is but it is a great pity that it is not in production yet!
Should have been put into the new RX8!

Carl, where are the 6 port inlets for the centre rotor?

[20B_boy]

Guess it will be PP\'d?

[SmbFD3S]

Very nice Will be interesting to see main power differences between this and an REW shortblock if they can be given....

Good point Mullins well spotted, does this mean the centre Rotor will get different air flow then Rotor 1 or 2?

I\'d assumed it will be PP\'d, as with a \'normal\' 13B 3-rotor? Matching them otherwise could be interesting :3Confused

Was told by somebody else that the rx8 rotors are lighter too ! Will rev much higher too !

The RX8 rotors I have seen are no lighter than FD ones.I don\'t see any holes for peripheral ports,probably a good thing as we know how slow that would be!

I don\'t see any holes for peripheral ports

I was thinking it was a mock up block, but it looks like the poo\'d up so may be not.
