Renasis vs. 13B short blocks
 

Anyone have any information on the differnaces between the the Renasis short block and the last incarnation of the 13B, aside from the port shape/location? I.E. does anyone have transmission bolt patterns, intake/exhaust manifold bolt patterns/ prints for Renasis or are they the same. Also, does anyone have information on the stock RX-8 Renasis intake and how it's controled (ECU or vaccuum)?

tranny is the same
