Why are companys like JWT and Stillen so reluctant to reply to e mails from England. Over here nobody really tunes the SR20DE. I now have two SR20DE 94 onwards spec motors sitting on the workshop floor ready for mods. I would love to use American based companys but my enquiries go unheard. I have a rough idea of what can be done to these great motors. But I would like prices and specifications and power output figures.
