Engine swaps? i dont understand but i am new



  • @b9d8306477=ukmx3admin:

    Fuel filter £2.5

    Tell me were you get your fuel filter please, mine cost a bomb?



  • Mechanic,

    Does your 1.8 gearbox not screem with the 2.5 bolted on? It will only do 135mph in 5th a 7000rpm..



  • It does struggle a bit, i have a spare K8 gerabox that i am gonna play with.
    My KLZE rev's to 8000 rpm, i dont hold it in that band but when i need to get moving i do use it. :shock:



  • I guess that give you a theoricial top speed on the limiter at 154 mph on standard 15" mx3 alloys? Im surprised the gearbox and clutch can handle the torque…!!

    Makes me want to replace my engine! I must affect the handling though with that extra nose weight?



  • I have a stage 1 exedy clutch, a little heavy but doesnt slip.



  • @4d09ae790a=pdtrewern:

    It must affect the handling though with that extra nose weight?

    It's 6lbs heavier than 1.8 ;) Replace the stock exhaust with ebay headers and you've probably less weight over front, so don't worry about that!



  • possibly yess with the theoretical top speed, but i saaw 157.8 on gps down hanger straight in min
    bearing in mind i have 2 fiberglass buckets and a roll cage and a relocated battery and had virtually nothing in the tank, but… personally i rekon she had more
    i run an mx6 box with a "3" flywheel in mine though, only difference with the 6's box is it has a longer 5th... possibly the reason??



  • yea think the mx6/626 box has taller final gear, meaning all gears are longer, but also a longer 5th. I can never remember that correctly though :lol: But that's some speed, well done! And legal :D



  • yep that's the reason you could reach that speed…

    normal mx-3 tranny wouldn't go that high with the gearing...



  • With standard MX3 tranny i got 145mph on the GPS at just over 8000 revs.

    japs always get it right.
