3.0L turbo mx3



  • youve all hurd of the klze 2.5L turbo mx3
    but has any one made a 3.0L turbo mx3
    this is my future project put in a klze to run for a year or so whal i save for the rest of the work
    then when my k8 is out rebuild it as a 3.0L new pistons and linters port the heads and over sized valves reground crank litend flywheel and many other litle jobs lol



  • sounds like fun mate.

    on a side note I'm not far from you…



  • would it not be better boring the klze to 3.0 rather than the k8? and then you only have to do one swap!



  • yeh but i wann have some more power for now to have fun with keep my mood up whal i wate coz its gonna take a year or to to save up for all the bits needed to make it a 3.0l



  • I'd love to see this, but I get the feeling boring out a k8 block that much is going to leave about 1mm of casing?! Would it not be easier/cheaper/better to overbore to 2.6 or maybe push to 2.7 and uprate internals - forged rods, wiseco piston heads etc then run a more reliable turbo setup? A few guys on mx-3.com have over bored, but I think its only to 2.65l or so. Good luck though, I'd love you to prove my thinking wrong :D



  • hum good pint will have to see what happens
    might just have to stick with a 2.5 turbo
    geting close to my ze only another 400 to get so nearly there but got to get tax this week so back down 100 damn so month or so till i get a ze then i must fined a 2.5 lsd box



  • Let me know if you source an LSD box. Seem to be like hens teeth! Also, if you really want to go turbo route the klDE is generally the better base, lower compression ratio = higher PSI. Lots of this on mx-3.com forums :wink:



  • true but its just not the same as saying youve ok a ze and the ze just has more power standard its gonna take a while to save for the turbo how much higher can you boost a de any way ?



  • If you want more power than a standard KLZE then the BPT swap will get you more… I have seen them well over 300+bhp. A KLZE turbo will only net you up to 250 bhp. A KLDE turbo will probably give you a bit more to play with.

    But at that much BHP whats the point of having a front wheel drive car? And would you really want it as road car?

    If you want to go fast cheap get a MR2 REV 3 Turbo with the GT4 engine in it, it does 0-60 in under 6 sec from stock and you can pick up a good one for under £4000. Or if you can streach to £4500 - £5000 get a Mitsubishi Evo 3 they do 0-60 in under 5 sec from stock. Or if you want to go really cheap get a Calibra/Cavalier AWD Turbo for under £2500 they do around 6.5 sec 0-60. Or if you want looks and speed for very cheap go for any MR2 Turbo 0-60 in under 6.5 sec for under £3000. Or the Honda Prelude 2.2vti its around £3000 and does 0-60 in 6.5 ish. And thats not going into hatchbacks as they suck.

    My point being, if you want a seriously fast 250+bhp MX-3 thats actually worth having then you need to do an AWD swap from a 323 GTX/R or spend a shed load on a LSD like Quaife (£1500) and a very good Suspension Setup at least another £600 - £1200 and a quality set of tyres £200+ and then you need new brakes so you don't wrap it round a lampost £300 - £1200, and an exhaust system up to the job £300+ then the cost of a KLZE swap £600 - £900. And the price of the MX-3 in the first place £400 - £1200 And you've still got a FWD car.

    If your an MX-3 nutt like me then fair enough, but if its speed your after then there are cheaper and better ways to get it than a modded MX-3.



  • Well lets not forget mikees/JTs klze turbo nos.
    Approx:
    1000 car
    650 engine
    2000 turbo & management
    500 nos

    350hp+ on 0.8bar for a bit over 4k. Beating skylines around a track, sounds like fun to me :D

    Yea there's better routes to fast cars than mx3s, but for me the mx3s looks and rareness add up to a car I happily blow money on.

    An mx3 with a klze is going to beat alot of cars often worth twice as much. But an LSD would make that power alot more useable, theres an LSD jspec gearbox on US ebay for $550 atm. So could probably have it in your hands for £400.

    this is what made me want to do a ze turbo
    ive got my mx3 allredy and love its handaling just want it to be a bit faster
    its been lowwerd dont know how much by but coments on hear looks to be 40-45 mm thers a ze in london dont 30 000 just imported from japan i can have for 800 i can do the swap my self and im shore that company could fined me the 2.5 lsd box
    not going as far as nos



  • cool, what company is it? See if you can get a quote for the lsd box, I would be very interested!



  • sorry to go off the point but is it easier to source a DE rather than a ZE ,and is it worth putting a DE in my mx 3.



  • yeh de are easyer to get but have less powere than the ze
    and im trying to get a quote for the lsd i sent them an email just wateing for reply



  • would be quite costaly to have it all bored out etc..

    better off putting the money into a engine with power from the start.



  • yeh think im sticking with the 2.5 ze turbo



  • just watched wellys video come on gt4 must be the way forward what a car :D



  • yeh if you like that sort of thing i love v engines so i couldent ditch my k8 for a 4 cylinder thing how ever powerful it may be



  • as Marco says, boring out like you want will never work, you'll blow holes in the cylinder walls at idle :?

    hmmm wrong…. there is a guy out here In Ontario whom I have met and seen his car since he built my buddys turbo setup. He has 540BHP on a ZE..... it's right here
