toybox Posted October 17, 2006 Report Share Posted October 17, 2006 hey people I'm looking down the path of a 12a or 13b swap into the ke38 just wondering if any one has tryed this before? Quote Link to comment Share on other sites More sharing options...
ScottKE1X Posted October 18, 2006 Report Share Posted October 18, 2006 Plenty of rota rollas about, it can definately be done... All i would suggest is that a NA 12a may not be torquey enough in the wagon. My bro put a 12a in his mazda 626 and it wasnt all that good. my 2c. so yeah, how much cash you got?

pozman Posted October 29, 2006 Report Share Posted October 29, 2006 you have to be creful, a mate and i looked into this a while back for a ke55. you can only legaly go as big as a 12a they wont rego a 13b as its over the size limits. remember legally the rotors are refersted as double capacity. i.e. 12a =2.4lt and 13b =2.6lt Quote Link to comment Share on other sites More sharing options...
PMP020 Posted November 1, 2006 Report Share Posted November 1, 2006 legal schmegal. bottom line is yes it can be done, and has been done many times before. if u got the brains, times and moneys, get it done coz a rota rolla wags would be phatness. cheers scott Quote Link to comment Share on other sites More sharing options...
Jordan Posted November 4, 2006 Report Share Posted November 4, 2006 (edited) don't bother much with a 12a, they're all older than 1988, and have all been thrashed. (Hey it's a rota, they all get thashed) 13b-6ports that came in the NA FC3S RX7 (series 4 and 5) are not bad if you're not going to be porting it. If you are however, get a turbo block (4 port) and have it rebuilt with NA rotars (higher comp) with an extend or bridge port. A single 48mm IDA weber and the thing will sound tuff as nuts. Out of a good bridge port you can be looking at 130kw+ at the rear wheels. Keep in mind though that the wilder the port the worse the low end ride. BP's wont idle much below 1300/1500RPM andmay buck and kick a little while cruzing at low speed. jordan Edited November 4, 2006 by Jordan Quote Link to comment Share on other sites More sharing options...
