KL - DE

hgallegos915 · Post by **hgallegos915** » August 7th, 2004, 2:06 am

Im noticing that KL DE swap is more likely to happen than the klze. Since its way cheaper and I can do the work myself. I tried using the search tool but well no luck there. Im guessing the swap is the same as the klze? what about sensors? and do they come with a curved meck? Its 190 hp right? and around how much does it cost?? what exact year make model car does it come ? my car is a 92 manual mx3. any help and tips appreciated. Oh and what about the ecu? do i have to get it also and the vaf?

the swap is the same as doing a KL-ZE, the sensors should all be the same, they come with a shot neck intake that will fit in our car fine they come from 626s, MX-6s and Probe GT i dont know years and you will need the ECU and VAF

Two of the four articles in Engine Swap Info on this site are KLDE swaps. The engine is 165 to 170 hp, depending on year/model, but the torque is nearly as much as a KLZE.

Sorry to steal the thread. But I'm also gonna do a KL-DE swap. Just want to check so I'm 100% sure. I have a '93 MX-3 and want to know what KL-DE engine I should get. I think I read somewhere that '92 and '93 KL-DE fits with no problem, but that the newer ones (starting '94) has other O2 sensors, right?

The O2 sensors aren't on the engine themselves, so it doesn't matter. You're just swapping in the block itself, so as long as the ECU is a 93-94 you're OK.

I also want to do this swap, I just need to know from what exact car oes it come from. I have been quited from 300 to 500 for a klde engine..not bad for almost the same torue as klze, and not to mention easier to find. I hear some even come with a curved neck already. I guess they are from a 92 probe gt? since my car is a 92 gs? also 93 works i think? anyone?

The year simply does not matter. Just get one you think has the least miles and the best compression (usually goes together

)

The only points of difference over the years are that they stopped fitting the third coolant temperature sensor at some time, and the distributor 3 pin connector wiring changed. If your MX-3 has that sensor, the KLDE ECU came from a car which had that sensor (or you don't know and it might have), and your new engine does not, either fit it into the coolant neck, or swap coolant necks while the engines are out of the car. As for the disty, just use the one from your MX-3, then the harness will continue to match the distributor.

The stuff about OBDII is irrelevant. The engine does not change. You still use your old exhaust tract, so you keep the two O2 sensor setup.

I think the IMs out of N. American and European Probes, 626s and MX-6s are short straight ones, which will fit your car. (Someone correct me if I'm wrong on that) The IMs which won't fit (without some imaginative messing around with engine mounts, anyway) are the long straight ones on KLZEs, which is why people want the curved neck IMs from Millenias. If your new engine has the short straight IM, or the curved neck, just use it. If you have a choice, go for the curved neck, because it came from a Millenia, and Millenia drivers tend to be less exuberent. You are unlikely to find a KLDE with a long straight KLZE IM, but if you do, walk away, it's probably been hammered by a swapper already

Thanks IanL.
The KL-DE engines here has straight IM, but it looks short to me. So I think that there will be no problem.

Will the exhaust (extractor??) from my K8 fit the KL-DE? Or do I have to modify it to fit?

Going to buy these things:
Mazdaspeed engine mounts (do I need SRD Engine Mount Member Bushings if I buy the engine mounts?)
Cork Sport Bronze Oil Bushings
Cork Sport SS Clutch Line
Exedy clutch (AC2 2 is too expensive, and I think that it'll be enough for the KL-DE, not going to dragrace with it)
SRD Shifter Extension Rod Bushing
New waterpump
New timing belt and the two other belts

Anything else I should think about? Or anything I have forgot to buy?

exhaust for your K8 should bolt right up.. in long run you might want to replace that to get a little more performance, but for the moment your existing exhaust manifold should work just fine

far as your list goes...
gaskets?
Plugs?
Plug wires?
oil & filter
coolant

when is last time you changed trans fluid? If it's time for that, it might be easier to do that when you have engine out of the car

Yepp, will buy a new exhaust sytem after the swap. But standard will do until then.

Yes, I will change transfluid also (Redline MT90).
Of course I will change oil and oilfilter. Cooltant, plugs and wires also, but thanks for reminding me

How about the NGK 'KL-ZE' Spark Plugs (ZE, V6)? Are they good for the KL-DE also? Or should I buy standard NGK?

What gaskets do I need?

I'm so excited. I hope the swap is quite easy. A friend of mine has changed engine in some old volvos, so I hope he can help me. Though old Volvo engines don't have that much technic stuff, but I hope that the workshop manual can help me if we bump into any probs.

Everything interchanges...I don't see why ppl keep asking "does this fit, does that fit?".

To answer all future questions: ALL FRIGGIN COMPONENTS OFF ALL K-SERIES ENGINES INTERCHANGE!!!!

This means, if you get a klde with only 2 coolant sensors instead of 3, just swap the neck. If you can't fit the straight-neck manifold, use your K8 manifold. The exhaust manifolds are all the same, hence why aftermarket headers fit our car as well.

Everything interchanges!!!!

Consider a KL or KF or ZE swap the same as taking your POS K8 out and installing another K8, its the same amount of work.

The reason that I ask, acording to you, an obvious question, is that I want to be 100% sure about the things before I start. In my world this swap is a big thing to do, and I don't want anything to go wrong.

MikeUK · Post by **MikeUK** » August 9th, 2004, 5:34 am

Id be the same, any time your attempting something new you want to ask as many questions as possible so everything goes smoothly. Theres nothing worse than starting a project and then finding out half way through that you forgot something or something dosent fit. I didnt know every thing was interchangeable with the K-serise engines, cheers for clearing that one up. Good luck with the SWAP.

Wasnt there a guy on this site who was going to do a web page dedicated to the Engine swaps? What ever happened to that? It would be good to have a page on this site dedicated to the facts of doing the Engine swap?

Tempus · Post by **Tempus** » August 10th, 2004, 2:40 am

There are several swap pages.. you can find links to a bunch of them from the main 'engine swap' page here at mx-3.com

Once you get the existing motor out, compare all the mounting brackets. Depending on where your KL came from, you might need to swap a few over. (as an example, mine game from a ProbeGT, and the one under the timing belt cover had to be swapped for the one that was on my K8.

I will get the engine from a 626. Is there anything better with a newer engine (except that it is new)? Found one from 1993 for $650 (180000km) and one from 1996 for $1000 (152000km). But maybe it's better the find an engine with good compression than a newer one?

Oh, and I still want to know if I need SRD Engine Mount Member Bushings if I buy the MazdaSpeed engine mounts?
