Xedos 6 2.0 v6 change engine to 2.5 (KL-ZE) ?
 

Change engine from 2.0l (KF) to 2.5l KL-ZE
Hello!
I would like to change my engine 1995 Xedos 6 2.0 v6 to 2.5l.
Is it just to change or do i need do anything special??

Will the mx-6 2.5 kl-ze fit??

Do i need to change the ecu?

Thanx!!

Ändern Motor von 2,0 l (KF), um 2.5l KL-ZE
Hallo!
Ich möchte mein Motor 1995 Xedos 6 2.0 V6 2.5l zu ändern.
Ist es nur, um zu ändern, oder muss ich tun, etwas Besonderes ??

Will der MX-6 2,5 kl-ze fit ??

Muss ich an die ECU zu ändern?

Thanx !!

Swap to KLZE is tricky, wiring is different. The KLZE has no EGR.

Easyer is the KLDE from X9 and it makes more sense.

KLDE block with KL31 camshafts and the straight short intake manifold from ZE.


Stable power around 170-180hp.

Wiring and ECU could be the same in this configuration.

A popular and often made modification is an engine swap to the standard european KL from 626 GE, MX-6 GE6, Xedos 9 or Ford Probe II. It's completely plug 'n play when keeping original gearbox, ECU, intake system with its mass air flow sensor, throttle flap, intake manifold and all other components from Xedos 6 - except motor/engine/cylinder block.

If doing so check if your original engine has a knock sensor - if it has a knock sensor you need a KL which has a knock sensor too. But as far as I remember all KL's have knock sensors.

If using another intake system with the different MAF/MAP sensor you will need the compatible ECU. But it depends on the intake manifold if it fits or if you run in trouble with insufficient space...

Wirthenson, could you please write exacltly witch KL engine you mean?
Sounds perfekt if its plug and play.

Im gonne buy engine soon so i need to now :)
My xedos is 1995 2.0 v6 nr2 KF engine.

How exactly do you need it? I don't know what I could say more than "standard european KL from 626 GE, MX-6 GE6, Xedos 9 or Ford Probe II". Just the KL (or often named as KL-DE) originally fitted to 626, MX-6, Xedos oder Probe... :think:

Ok so the engine KL is KL-DE.
I have one i could buy in sweden used from mx6 1992 2.5l manual.

Mine is 1995 (version2) automatic.

Could it be any problems?

So plug and play. I can use my databox ecu?
:)

Take that MX-6, take its engine, remove anything except from motor block up to cylinder heads and valve covers and use any other original part from your Xedos 6. Mount that into car body, plug in all that connectors wherever they were and you've finished. Enjoy that torque and forget the existence of all that KF-parts on your new KL.

Anything else is much much more complex...

Great!

And that i have second version is not a problem?
Automatic wheel from my to the kl engine( manual gear) ?
Intake manifold, startengine, steering cylinder from KF works with KL?
distributor cap is the same on 2.5 and will work?
Any more info thats important before i do this project?

Thanx!!! ;)

My car i automatic but can i use a engine KL-DE only with manual gear if the switch the wheel?

Thanx!

What you mean with "Wheel"? Stearing wheel?

I mean the "flywheel" between engine and gearbox.. Don't know the technical english word ;-/

Can i take the flywheel from my automatic 2.0 v6 engine att put on the mx-6 2.5 engine if its been with a manual gearbox!?

Wielen Dank! = )

Ok, understood!
Yes, flywheel is the right english word for that!

Ok Great!! = )
And if I want more power i use the KL-ZE air intake manifold instead of the KL-DE? How much does this? = )

Last question about this.. i think..

If I Take a Xedos 9 KL-DE engine the problem is the intake manifold is to big for Xedos 6? It will not fit in the engine room?

The MX6 engine is rare. Easier to get Xedos 9 2.5 v6 engine!

Is the Xedos 9 2.5 v6 also easy to swap like the mx6 engine?

That is no problem, cause you use the intake manifold from your X6.

It make sense to put the throttle from 2.5l on your X6 manifold.

I dont know about the one from X9, Probe and MX6 throttle fits to X6 manifold.

Compare with pictures will help you.

DISTRIBUTOR and THROTTLE
 

DISTRIBUTOR

Do I have to have the distributor from MX6 KL 2.5 v6 or can I use from Xedos 6 KF 2.0 v6?

THROTTLE

Can i use the KF 2.0 v6 Throttle to MX6 KL 2.5 v6 engine?


Any more I have to have to make it work?
I thought i could use the block and head and move the other parts from my 2.0 v6 engine?
I also se that part number is different if you have manual and automatic box for throttle
and part picture is different! :-/

Anders

You must use the DISTRIBUTOR from your X6 cause there different types.

You can use the throttle from X6 but with the one from MX6 it accerlerate better cause the diameter is bigger.

Ok So it will fit to the 2.5l head?

I have 7 ignition cabels. one for the ignition coil!

Yes you must change the complete, not only the cap.
Ignition must be regulatet after that with strobo light and the mark on the timing belt cover.

Should you set the timing for 10 or do you think 13-14 is ok?

yes! ok thanx for the help here!!
I think I've got it now = ))

Thank you very much!! = )

Ford Probe 2.5 v6
 

Will the Ford probe V6 engine work also?
If it has egr and nocksensor?

= )

Yes it work. The camshaft cover can be replaced with a Mazda signed.
In my opinion the X6 has no Nocksensor an he don´t need it. Thats no problem, all sensor witch have no part on the main wiring, need no attention.

Gaskets...
 

Hi there! = )
This week i will get the (ford Probe -93) KL 2.5l v6 engine!

I need to buy some gaskets. Kan i buy from a mazda dealer to the ford probe engine? I guess the answer is yes but I first check here with you = )

Thank!!
Anders

In fact the parts should be the same, if you by it at Mazda dealer or Ford dealer.
But I expect lower prices at Ford dealer!

You can also buy the gaskets and timing belt kit from Ebay.com

waterpump are different at the wheel.
There you have to look which on is the right.

Only from the camshaft covers you should buy original Mazda parts.
They are the only one who get seal.

When you buy from US the shipping is more expensive than Germany and you get tax sometimes..
Any good on Ebay.de ??

Thanx!!!

You need to compare.
I made the experiance, that althoug you have higher shipping costs and import taxes that its cheaper sometimes.

I don't know how its handeled in sweden, but I expect its similar as in Austria.
If I import from US I need to calculate the prices as follows:

item prices in USD + shipping in USD (good average 50-70 USD) = total USD

convert total USD to local currency and add appr. 23% (appr. 3% customs and 20% tax)


At the moment the Dollar-EUR exchange rate is not so good for this. But especially if you compare the prices from eBay.com with prices at local Mazda/Ford dealer it makes often sence to buy from US.

DISTRIBUTOR
 

Just want to check one more time that its possible to
connect the Xedos 6 2.0 V6 distributor to the head of the KL 2.5 engine.

Check the picture. They are different also. My Xedos 6 har seven ignition cabels. one extra for the ignition coil. The connection on KL 2.5 engine has one extra electric connection. (is it the coil inside?)

No problem to connect it?

Thanx!!

The connection to the camshaft is the same, that is the only important thing.

Youre right the KF in the X6 has more ignition cables, that is the reason why you must use the complete one from X6 KF.

The Xedos 6 with its original KF has seven ignition cables, because the seventh cable connects the distributor with the external ignition coil. K-Series V6 in other models have six ignition cables only, because there is the ignition coil integrated into the distributor.

Due to this fact, you can not simply replace the KF distributor with a KL distributor without changing the cable harness and the ECU.

Thanks!

I Will use the KF 2.0 Distributor!

Engine
 

Hello!
What direction do you take out the engine? Up or down? = )

The best and easiest direction?

Thanx!!

i guess that depends on your circumstances: if you have a crane, you probably want to lift it (up); if you have a service lift, you probably want to "drop" it (down).
i have removed some k-engines from cars and always lifted them. but don't forget: therefore, you need to detach the exhaust system first. i usually unbolt the exhaust manifold directly at the cylinder heads. therefore, it's best to go under the car (something like a service lift or ramp comes in handy) - also to detach the engine hangers (which hold the engine in the car) and the axles...

VRIS 2.0 to 2.5
 

Hello again and thanks for the help before regarding changing engine from 2.0 to 2.5 v6.

Intake manifold:
We are almost there but now is the question about the VRIS and its look like some differens. I have two pictures taken. please look at them an explain if it will be problems with something. The location is not the same and the vacuum is not exactly the same setting.

Do i have to change the to the intake manifold of the 2.0 KF engine or will this work also?

THANX!!

Hello.

I cannot answer your question, but I have following recommendation to you:
Would highly recommend to remove all original vacuum hoses and use new silicon ones. I did the same at my Xedos 9, because all of them are min. 17 years old and possibillity for leackages is very high. Especially in your case when all of them are outside the car.
As you in any case have them more or less "in your hand" and easy to change with disassembled intake manifold.

Greetings.

PS: I mean something like this: http://www.ebay.de/itm/Original-Samc...item51c60613f6

Just select the right inside diameter.

You have the answer some posts above.

Use the the complete manifold from KF engine.

You should transfer the throttle from KL manifold to kf manifold.

drive axel mount doesn't fit the 2.5 KL engine :-/
 

Not much left now for the engine swap to 2.5 KL but now the drive axel mount
doesn't fint from my 2.0 Xedos 6 to the KL 2.5. only one hole is there.

Do i need to buy other for the 2.5 KL engine? From MX-6 or ford probe?

Im added a picture.

Do you have any idees?
THANKS

Are you trying to use the gear box or drive shafts from the KL instead of the original parts from your Xedos 6?

You need to mount your X6's original gear box to the KL. The KL, KF and K8 are compatible, the gear boxes and the drive shafts aren't.

no I'm using the the gearbox from my 2.0 v6 Automatic.

Shouldn't this part be screwed to the gear box (which indeed is still the same as before)? Or do I remember wrong?

the mechanic man says that on the picture (KF 2.0 engine) the finger points at a hole that doesn't exists on the 2.5 engine.

?

Yes, this is wrong.
The "indermediate axle" will be mounted in the opposite way as shown on the picture. In the gearbox there is only the "teeth-connection" and on the right side there is the bearing. And the body of this bearing should be screwed to the engine block. In my case (Xedos 9 KL manual gear) there where 3 holes, but 2 screws.

@aw_309:
Please confirm: In your case only one hole of the bearing body will match with screwed hole of the block?

I made numbers to the holes in your picture:

https://lh3.googleusercontent.com/-R...2/IMG_3010.jpg


1.) Please confirm, that hole nr. 1 and 2 was screwed at your KF block.
2.) Please confirm, for which hole nr. now is missing screwed hole in the block.
3.) Please check, if at KL block there is a screwed hole at nr. 3.

"In your case only one hole of the bearing body will match with screwed hole of the block?"

Yes the 2.5 block, only one hole will fit the bearing body!

So now i need to buy the bearing body? from a MX-6 (2.5) or ford probe or will Xedos 9 2.5 work??

Possible to modifie the bearing body that i have? :-/ Maby difficult to get this part!!

Once I did my swap, I had the same problem and I had take the risk to use only one screw.
After 30TKM I had no problems. It make sense to check that screw sometimes.

I think you only need the part from Ford Probe MX6 ore 626GE
http://www.japanautoteile.de/parts/files//919280199.jpg

aha only one screw!? sounds scary? :-/


I checked the technical drawings and its a mess!!
They changed all lot during some years.

So now i know that the drive shaft BRACKET, SHAFT JOINT for the 2.5 engine is different then the joint for 2.0. I found out that Mazda 626 and MX-6 has the right 3 holes mount BUT will my other parts on the drive shaft work? i got new joint set outer.

ALSO the bearing balls needs to change to new one!

ohhhh when will my car be ready... i hope soon!! = )

PICTURES!!

yes (hörnchenmeister) looks like that will fit!! =)

maby i just do like you with one bult!

Another option would be to drill the hole bigger and cut a bigger thread in the engine block. Otherwise you can use helicoil ore threaded bushings.

What is this connections for?
 

now when they almost is done with the engine swap the have two electric connections they don't understand fully.

Do you see what it could be?
The grey is near the top and it goes under some place and the black to the right comes from gearbox.

hmmmm :-/

Anyone?
THANKS!

The first one could be the watertemp sensor nearby the fillcap.
Not all Mazda V6 have there a sensor.

Can´t you compare with your KF?

Have you checked Nr. 3?
As below:

If at hole Nr. 3 there is a screwed hole at the block you could drill a hole in the bearing body and use that for second screw.

Please check. Maybe this hole will fit with Nr. 3 of your bearing body:

https://lh3.googleusercontent.com/-P...c42/image1.jpg

Yes i will check! = )

I must say thanks for the help here! Without you guys it would be much more problems and stress for me. :-) :-) :-)

What do you think about the connections??

The grey one and the black from the gearbox?? :-/

The grey one is not the tempsensor.

Today I picked upp the car and checked it. I noticed that the vris system doesnt react. The two wings with the vaccum doesnt move when im use the gas trohtle.

The mechanic has no idea. :-/

I will check by myself if there is faulty codes.

Any idea?
Thanks

For understanding here are some desriptions

https://www.youtube.com/watch?v=W1Pwa8wQu8k

I understand what VRIS does but it will not start turning around the right RPM.

= )

Did it work before you have swap the the engine?

Are all electrical connections ok.

The vacuum hoses must be ok as same.

The two VRIS elements have each a rod. This could be rusted.

And sometime the vacuum is not seal. Then it works not, too.

Strange but after some days it works again! :-)
No faulty codes before.

I missed to remove the throttle house adapter plate when we used the 2.5 throttle house. That sits between throttle house and the intake manifold. Will it do a lot to remove it? Ive seen that others with 2.5 V6 does not have it attached!

What do you think?

I don't really understand waht you mean.

Lite bit hard to explaine but ill try again = )


on Xedos 6 where the Trottle body is located there is a metal plate between the

intake manifold to the throttle body.

INTAKE MANIFOLD ---> metal plate (with four screw) ------> Throttle body

On the 2.5l V6 (mx6, 626 Ge, ford probe) they use no metal plate.

Will the car go better without the plate?

Thanx

How thick is the plate? Which material? Which color?
Maybe you mean the metal gasket....

If yes, there should always be a gasket!

Its not a gasket!
Plate, about 5mm thick.

Metal plate

Aha, interesting!
And there are then 2 gaskets?

I guess it is only because of distance problems. I see no other reason to mount such plate.
The plate has no other holes? Or something other is attached to the plate?

Vibrations around 1300rpm not driving
 

Vibrations around 1300 rpm when im not driving the car. In neutral and park

Its like: wrrrr-----wrrrr------wrrrr------wrrrrr


Could it be the engine mounts? There is three. Witch one is it often if there a problem with them?

What could it be else ? The engine shakes to much then normal.

Thanks!

If the engine is off, can you shake the engine? If there is no clearance in the engine mounts, its another problem.

I would spend the money and buy new air hose between throttle and filter.

No i cant move it!

yes I will buy new but this shaking is someting else.

I have fault code 25.
Solenoid - fuel regulator.

Checked the vaccum today and there is vaccum. Strange is that i dont have 12volt to the solenoid when the engine is running but maby its only sometimes?

Then I think this is not the problem.



OK, this could mean problem with the fuel pressure.
Which solednoid have you used? From the KL or from your KF?
