A couple of thoughts regarding the KJZE....., if we're assuming the KLZE + KL auto won't fit in an MX3, then why would the KJZE + KJ auto fit? does someone have access to the KJ auto tranny for some measurements?
also to answer a previous question, the last major KJ thread came to the conclusion that the MX3 5spd wouldn't be able to handle the amount of low-down torque the KJZE produces (without alterations)
as for ecu/harnesses etc....., i figured it would be easiest to go with a standalone system
FlyingMXer....., if you're gonna put the KLZE into your auto MX3, you'll need to use the K8 ecu to control the auto computer/transmission, and an Airflow Controller to ensure you don't run rich (ecu just dumps the fuel)
when mine was auto i used an intercept link (search on here for more info..., it was one of our irritating, unrelated discussions
)
ADathomir....., seriously, have a real good go at learning a manual transmission (perhaps get Dallas to take one for a test drive!), cos with the amount of torque the KL produces, it would be a piece-of-piss to drive
