No intention of racing but I have a turbocharged 20B on a test stand I plan to boost to 450 HP at 6500 RPM. = I haven=92t gotten it started yet, though I should be any time = now.

Thomas,

     One of the first things = I would do is make sure the powers that be in the = Sport

Class will not restrict you to a traditional piston = engine (like certain auto groups did

when the early rotarys were beating their B#%%'s) or penalize you with extra weight,

etc............Then the next problem in my mind will = be finding a prop reduction unit

that will stand up that much power...........Tracy = Crook will be the first to tell you that

his RD1X units were never designed for that much power..........IMHO

 

Very Interesting and Ambitious Project Though = !...........I am sure the Rotary Group

will follow and pull for you and offer all the = help they can............

Here you go everyone: The engine should be stamped on all = the rotor housings and sideplates. Look on the top of the rotor housings = where is says "Mazda 20B"


Pre A code: 3 digit  numbers only, no letter
A code : Letter A and 3 digit #

Pat,

     If your core engine still has the waterpump on it count the number of bolts

on the pump........86-88 13B has 7 WP bolts...........89-91 = has 8 WP bolts.....

 

    93-95 13B has an all aluminum = WP.......This is quick and dirty but there are

other ways if WP is missing...........The 86-91 WP is cast = iron bolted to alum

housing.........
