Re: 9-3 'HOT' ECM question Posted by JimBlake [Email] (#141) [Profile/Gallery] (more from JimBlake) on Fri, 18 Dec 2009 06:25:56 In Reply to: 9-3 'HOT' ECM question, scanav, Thu, 17 Dec 2009 14:59:06 Members do not see ads below this line. - Help Keep This Site Online - Signup |
There's a whole lot of hardware differences between a T-5 engine vs. a T-7 engine. Regardless of HOT or not.
T-7 has air mass-flow sensor, T-5 does not.
T-7 has motorized throttle body, T-5 does not.
T-5 has AICV (idle control valve), T-7 does not.
Lotsa wiring-harness changes to accomodate all this stuff.
You would have a much easier time swapping T-5 base for T-5 HOT, but there are still some hardware changes. Maybe the turbocharger itself is different?
