No such thing as an American KLZE. There is an American Kl03.
KLZE=JDM, 10:1compression pistons, more aggressive cams, no egr, external coil ignition system, rectangular intake ports on head, rectangular intake runners on intake manifold, and a huge kick in the a$$. 197-200 hp
KL03=ASPEC, 9:1 compression pistons(most), less aggressive cams, egr, internal coil ignition system, D shaped intake ports on head(most), D shaped intake runners on intake manifold(most), and a slight kick in the a$$. 164-1701hp

Isn't it technically KLDE

KL basic engine series
D Double overhead cam
E Electronic Fuel Injection

Someone correct me if this is wrong, but I thought I read that 'KL03' is a misnomer based on some of the numbers on the block or other parts..

K stands for the K-series V6 engine family

L stands for 2.5 liters

D = dohc

E = electronic fuel inj.


the Z means "performance model".

J stands for 2.3, F stands for 2.0 and 8 for 1.8

And ya, ppl who call it a kl03 are mislead & incorrect. I see lots of ppl call their BPZE's BP05's too b/c that is what is stamped on the engine block.

Yes, KL03 is wrong, KLDE is right. Common error.

Also newer KLZEs come with 9.2CR and 187 hp, see this link . They are all from Millenias, so have the curved neck manifold, which is not an MS8 manifold - another common error.

Hmm, I thought the DE meant domestic engine.

Anyway, how "new" of a ZE in a Millenia would have the lower CR? Did you see any production years?

I don't think so - that engine is in cars sold all over Europe as well as North America. If it was "domestic" the domicile would be Japan!

I don't know - but I know a man who might - ask on http://autos.groups.yahoo.com/group/mazdamx-3owners/ ; you may get a reply from Vaughn.

There is also the millenia engine in addition to the small port MX-6/probe engines. The millenia is essentially a ZE with different cams and pistons. Not sure if the us millenia engine has a different desigination than the probe motor though.

1998 KLDE MX-6/Probe and 626: 170 hp @6000, 163 ft lb @ 5000
1998 KLDE Millenia (N America) : 170 hp @5800, 160 ft lb @ 4800

I never really bought the Hp rating of the millenia. It has the better intake and heads but yet makes the same power as the normal klde? You can bolt a millenia intake manifold on a probe engine and gain 8-10 wheel hp. Would make you think the millenia should make 8-10hp more at least.

Yea, what I was trying to say but a lot better! I thought that people mistakeningly called it the KL-"DE" (and DE meant Domestic Engine). Anyway, you're right, it wouldn't make any sense to localize the KL-"DE" to N. America.

At a guess, the difference lies in the camshafts. Put a MX-6 camshaft in a Millenia engine and then measure....
