thanks every one for the input. by the way I plan on building one hell of a ka because after I buy all the nesscesary ems and fuel accessories and turbo accessories, if the thing ever dose blow up, I can just go to the yard grab another for a couple hundred, bring it to a machine shop and rebuild the bitch. where as some one with an sr would have to order it for anywhere from $1500-$2500, have it shipped here and hope it wasnt driven to hell.
