    have a look here mate

    http://www.mazdamad.forumwise.com/mazdamad-thread423.html

    and here

    http://www.mazdamad.forumwise.com/mazdamad-thread449.html

    Basically, I sold my old mx6 and bought this one then took it to the Nurburgring 10 days after I bought it. When I got back it went to a mate in Essex to get a full engine rebuild

    Then ran the engine in for 1000 miles and set about sorting other things.

    Its got, full powerflow exhaust system and stainless headers, thermoblock IM and TB spacers, uprated FPR, CAI kit, Tokico Illumina's and lowering springs, shortshifter, Fidenza flywheel and stage 2 clutch, Prosport gauges, etc etc.

    Getting megasquirt fitted at the end of the month then i'm either going Turbo or NOS depending on budget. I know the ZE is high compression so i'll have to look into what is safe to run with.

    Heres my rather eventful lap of the Nurburgring!

    @ab4c086206=Garfy1981:

    As far as i knew the mx6 only has a taller 5th gear. All other gears should be the same.

    **The ZE has a longer 5th and Final ratio.

    Also, those tyres will make the speeds 1.6% higher, give or take. Should still be good for 150mph at the top end.**

    150mph on a ZE?? No way you'd get that out of a K8 box, reckon mine will do 130mph - 135mph tops, Stu, we will have to have a drag race LOL

    **It's all down to the tyres.

    I've had 141mph (indicated) on Red. Gear ratios suggest that to be the maximum the gearbox will give. Tyres with a larger rolling radius lengthen the gearing.**

    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.

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

    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
