Check this: http://www.twelve100.com/faq%20and%20tech_pages/EC U%20USA%20AW11%204A-GZE.htm, that guy is saying, he's running a 4AGZE with Corolla GTS ECU and Supra AFM without to many trouble? So maybe 7M or 5M will work?- Maybe you can drop him a line. Would be interested, too. (Personally would say 100Aus$ aren't to much, have seen one some time ago on the net for 100US$- private sale), cheers.
