need confirmation

[DJester187]

I tries to do a search for a definate answer on my own only to come up with conflicting answers. So, (i apologize i do not have pictures) the engine that i swapped in, under the vanve cover has the kl01 stamped on the cams, but also had the "V-6 24 valve" stamp on it in english, as well as "mazda" up above it. It also sports a curved neck mani. with my vague description can anyone confirm which type kl engine i got? thanks.

Try this section of the engine swap FAQ

yeah, the engine came with no egr, but a place for the egr to be bolted. the manifold says kl86, or kl68 i think, if that helps. any ideas? or ways to solidify the kl type?

[Tempus]

What's on the heads? that's the definitive number to look for, according to the FAQ..

or post pictures, other folks might be able to tell you from them..

I cant find anything on my heads except for KL somewhere on the block with a buncha numbers under it....

The v-6 24 valve and mazda are on the manifold? If it is a curved neck manifold there isnt any place for it to be writtin on it.

you probably got a j-spec millenia engine..kl01 cams kl stamped on block curve neck manifold and no egr..looks like a ZE to me...about the mazda 24 valves written on it..it must be on the valve cover

[DJester187]

yeah blue is right, it is stamped on the valve cover. i think i said that in my original post. i am like 95% sure it was from a millenia, based on shematics and wiring and such. so then it is a ZE?!

[babyblueMX3]

yup

[DJester187]

awesome, thanks. now this would be the 197, or the 175 hp? i read on a post the curved neck ze's are lower compression or something giving it only 175. is this true or am i @ 195hp?

[babyblueMX3]

hrmmm..I guess it depends on the year of your ze..not sure if the 175hp ze had kl01 cams..We don't have much info on it...sorry bud can't help you with that...I know it exists but never heard of a person who got the 175hp ze..or didn't know about it

Not entirely true - it applies to later (don't know from when) curved neck ZEs, not early ones. I think it dates from a more stringent emissions policy in Japan, to which Mazda responded by de-tuning the engine a little.

[DJester187]

ok, so besides getting it dynoed is there anything i can look for/check/do to get a better idea of which hp model it is?

[PATDIESEL]

The only definate way to check is to look on the head or have it dynoed. I'm not usre if the old and new ZEs have the same head code though.

[DJester187]

ok...so does anyone know the the codes for the 175hp, and 195hp ZE? or is there any other way to identify them (outside of getting it dynoed of course)
