Engine swaps?



  • wow thanks all of that was really helpful. i do have a mechanic friend who will be doing most of the bolting up after i have got the 1.8 out. i will do as much as i can myself but just need him to assist me really to mke sure i do it right. how much do u want for the ze engine mate? i have gotta do some saving up lol. does it include ecu? thanks again guys. really appreciate it



  • guys who have ze engines for sale are ukadmin and kami, but admin is away on family business so wont be able to answer you for a while. If i was in your shoes i would buy djmarcos klze mx6. Take the engine and gearbox out as one complete unit. There would also be no need for clutch change, then take out djmarcos ecu and plug it into yours then i would take your 1.8 engine and gearbox and dump that straight into the mx6, plug in the ecu and flog the car on the cheap, as a 1.8 v6 lump is prob only worth £50. So you could prob sell the mx6 with 1.8 engine for couple of hundred, and re-coup some costs, or agree for your mechanic friend to have mx6 and 1.8 engine/gearbox for his labour efforts!!. I have seen a mx6 with a 1.8 engine in before and very little notice the difference lol.



  • oh if you do swap the 2.5 engine and 2.5 gearbox, the 1.8 flywheel is lighter so you would want to keep that to bolt to the 2.5 box, your get a better response with a lighter flywheel. You can get ulta light fidenza flywheels but are no way cheap!. Although if you have no intention of doing clutch change i would keep engine and box bolted and just drop it straight into mx-3.

    oh your also notice that the ze lump doesnt use a egr system, so your have no use for mx-3 1.8 egr system.



  • is marcos mx6 the silver one on ebay? i had a look at it earlier if it is. low milage engine. you guys are seem to know everything about these swaps lol. will the mx3 headers fit on a ze until i get the real deal? i know they are pretty restricted and wouldnt want to harm the 2.5 if i can help it. you must realise i am a complete noob at this. the only engine i have changed before is a 1.1 saxo engine which i could pick up myself. this is a totally different animal haha



  • It will restrict it and cause it to run rich, although it won't harm it. I had 146bhp with ze bolted to a complete stock 1.8 exhaust system and then after I done manifolds, sports cat, and exhaust went up to 188 bhp. Still got some tuning to do on mine. Mx3 gulf has 190 something on hes. It's not a bad idea if your trying to cut costs and do a gradual project build.

    Oh also also alot easier to do cam belt and water pump while engine out so I'd consider that too.



  • thats even better news for me as i am working to a budget. and besides 146hp is more than 130hp so it will make a slight difference with alot more torque until i get a stainless system fitted. i will try and save up for a full system from powerflow with sports cat etc but thats gonna be pretty expensive. as long as i know i can get the engine in and running the rest can wait for a few months. gotta save for an engine or mx6 yet. i would prbably do as you said which was to give my mate the 1.8 mx6 for payment. happy days



  • Yep. Metal prices are set for an all time high next year along with vat increase not good !.



  • might have to go out robbin old ladies lol. yeah its going up to 20% aint it? the best metal to invest in is gold by far! my partner and i used to buy and sell. our last batch went for over ten pounds per gram!! that was just your cheapy 9ct stuff as well. wish we kept it really cos will be worth alot more soon



  • sorry i forgot its a car forum haha



  • Just a quick word, DJ's MX6 is a auto so you will need to use gearbox from your car, I think the ECU is different on manuals & autos too, but not 100& certain



  • well m gearbox is fine. still feels tight. i will look into the ecu business. its ok if it is different as i dont exactly have pocketfulls of cash atm. i know i can pick up a probe round here for cheap so not really too bothered. i should get a job before i even think about big mods like this but i cant help myself :-)



  • If the ecus are different, then the vris points won't be the same, so they won't be compatible with each other, when I done KLDE swap, power gain was good :lol: if you can find a cheap probe thats a runner so you can see engine running then go for it, as you will have everything you need on car too, KLZE is more power but you will be looking at least double the price against a KLDE, + I have heard some KLZE's don't put out the alleged 192bhp, mines putting out 196bhp/180lb torque with a decat, stainless headers, lighter mx3 flywheel and uprated HT leads

    have a looky

  • just done a bit of research and it looks like an auto ecu will not work on a 5 speed manual gearbox due to the ecu having to know which gear it is in so it can change gears at certain rpm depnding on how hard it is driven. would a KLDE manual ecu work with a ZE engine.



  • i would hae a look but im on my crappy old tytn 2 phone and it doesnt do youtube very well



  • and yeah i can get a probe complete for reasonable money down here in the depths of cornwall. cars are cheap down here



  • For the ze there is two ecu s the kl36 for auto and kl31 manual. Either will run the ze coupled with a manual gearbox. Kl36 will throw out some codes on diagnostic mode as it won't find the auto sensors. there is no engine management light on obd1 so you will never know. However you won't be able to use your 1.8 back in the mx6 with the 1.8 manual ecu to run the mx6 auto box like you said.
    I use the kl36 ecu on mine and have no problems with vris points and dyno is pretty smooth.



  • Oh if you got ze engine you could use a chipped de ecu and de vaf. Search for probeinator chip.



  • Did not know you had a kl36 ecu garfy, apologies!! KLDE ecu will run a ZE same as a K8 will too, you just won't get full performance out of engine though



  • No but you can use a de vaf and de ecu get it chipped with even better vris points, improved rev limits and better no 118mph limiter as found on ze ecu.



  • 118mph? ive had more than that indicated on my speedo with a blip with a range rover sport. it was indicating 132mph and the wipers were being pushed up the windscreen. so anyway the ze will run with a k8 ecu but will run very rough right?and if i were to buy an mx6 auto would that ecu run with the auto box bolted to the 1.8? sorry for all the questions
