KLZE vs MX3 gearbox



  • speedos are not accurate, I have hit 120mph and road angel was saying 112mph, i'm on standard 15" rims



  • Thats what i'm after, lower top speed but gets there quicker.

    Might have to just bite the bullet and try it, should be fun.

    Paul, you're about 300kg lighter than me and mines only pushing out 188 bhp mate so you'll whip my ass.

    Once i've got the megasquirt on, and a shiney bottle of nos, then come and see me :D



  • **Preaching to the choir - I don't even read my speedo in Red. But do the math.

    K8 5th - 0.795:1
    K8 Final - 4.388:1
    Engine speed 7,000rpm = output shaft/hub speed of 2006.62rpm

    205/55R15
    Tyre diameter = 23.877"
    Tyre circumference = 75.015" (distance per revolution)

    2006.62rpm * 75.015"/revolution = 142.54mph @ 7,000rpm

    205/40R17 tyres are 1.6% smaller, which is good for 140mph (140.03mph). Push the revs to 7,200 and you have 144mph (144.03mph). Close enough to 150mph for my likes - and the ZE should have enough power to overcome the MX-3's aero limit.**



  • i'm on 205 40 17's mate, whats that calc at?

    Also, I have no limiter but according to my dyno run I make peak power at 6250 rpm so would only take it past 7k in 5th anyway.



  • Sorry, mistype - that is for your 205/40R17s.



  • I'll have a mx3 box out of the 3 im breaking at the mo if your interested?
    Also dont mean to be stupid as im still learning but what is "megasquirt"?



  • ECU piggyback (or standalone) designed to extract more power by adjusting the fuelling and fuel/air ratio.

    Cheers famine, was on the verge of google-in it.



  • I'm going for a stand alone megasquirt which does away with the VRIS, VAF, Dizzy and ECU and replaces it with a mappable ecu, coil pack and EDIS unit. Should gain me about 25bhp and as said, it controls fuel and spark.

    Once fitted I will have a KL36 KLZE ecu for sale :D

    brilliant thanks so thats 1st dibs lol

    sorry guys a bit off topic

    when i come to do my ze i have a choice between a kl-de and a k8 gear box im using the car for drag racing so would it be best with the k8 box or the kl-de box the engine is a millenia ze curve neck



  • K8 Box 100%



  • thanks mxgulf



  • **Agreed - on a normal road, you might struggle for grip booting it in 1st or 2nd, but on a high-friction drag strip with slicks or cheaters, the shorter ratios will be win.

    I still have a spare, 86k old K8 'box :D**
