Bruce,
If you can find the aluminum 20B intermediate housing anywhere please= let me know who is making it. The price for the STOCK cast iron 20B inter= mediate housing has gone to about $5000.00 on the retail market. I know,= Steve and I have been trying to buy one! The stock 20 B intermediate hous= ing weighs 49 pounds! The side housings George was mentioning were custom= lightweight housings made in steel that weigh about 1 pound more than the= all aluminum housings IE. in a 2 rotor they would be about 3 pounds over= the all aluminum parts. The advantage is that you can gas nitride th= em just like the stock parts. None of the available aluminum housings has= ever been run in a long term high-output engine. The Factory Mazda 26B 4= rotor Le Mans engine used aluminum sideplates with an exotic de= tonation gun applied ceramic coating. No one has reproduced those hou= sings for sale. To my knowledge none of our flying rotaries has used the= Racing Beat housings, which are available only for the 13B and are VERY= pricey. They also have been notorious for extending delivery times on tho= se housings.
