KLDE/KLZE Gear box
Quick question are they both the same?
**I researched this a while back, but I've lost all my sources. Put as much faith in this answer as you think it deserves.
The normal MX-6 has the same gear ratios as the ZE, but the output shaft is geared 4.388:1 compared to the ZE box's 4.110:1
So at 7,000rpm in 5th (0.717:1) your wheels (assume 225/45R16) are turning at 158.7mph with the DE's box compared to 169.4mph with the ZE's box.**
