Is the timing belt going to need to be a custom length?

Love this project and the good cross platforming going on here. Just out a of curiosity, Did you happen to to try to see if the zm-de cams fit in the b6 head? If so that could be a cheap easy way to convert a b6 to a solid lifter setup.

Anxiously awaiting an update to this thread. I know it's been over a year since the O.P. updated, or was active on this site, but this is a very well thought out and documented hybrid and it answered some the questions I have had regarding the z series engines. Does anyone know if the valve footprint of the ZM head is drastically different than the B6? Basically, will the valve reliefs in my forged B6 pistons work with a ZM head?

Cool

Hi all,

Exellent thread!

I had some left over question about Z engines and some were answered here.
Great works on that B6 lump.

Now I'm asking myself if the ZJ engine (aluminium block and oposed intake/exhaust head) can make a good source for a aluminium block. (with ZL VE head on it)

Can't wait the next part of the story

I picked up a zm to do a hybrid with and Im doing some testing while I tear it down. Haven't dug out one of my b6t heads yet to try the zm stuff in it, but this is what I've found so far.

B6t cams in the zm. The cam journal spacing is correct and so is the cam diameter (checked with a micrometer).


Intake cam wont fit without some trimming.


Now while the cams do fit in the head there are some things that I think will prevent us from using b series cams in a z series head. On the exhaust cam there doesn't appear to be any oiling ports in the head at the camshaft journals. It looks to me like the cam has the oil passages drilled into it and oil is fed through the cam from a main port at the front journal to the other journals. For some reason this is only on the exhaust cam though.

Exhaust cam oiling port


Feed port on exhaust cam


You can see the feed in the left journal and lack of ports on the right journal


Then on the intake side there's ports in both


And no holes in the cam either.


Now the lifters. They are the same height and width(checked with micrometer).



So they will fit in the lifter bores on a b series but the height inside where they touch the valve is different. The solid lifter is .368 thick and the hla is .721 thick. So I doubt we can use a zm lifter in a b series.

From what little I've read on the the zj/zy motors I'm starting to think that they are based on the mzr not the b/z families. Aluminum block, reversed head flow and it uses a timing chain. If you look at the air filter on this cutaway its labeled mzr 1.3.

Hi, thanks for your input!

I made some ressearches about the aluminium block and sadly I think there is no cheap way to have an alloy block for our Head.

I found this picture of a ZJ Head and I think the holding holes are not matching

@B6Tfastiva:

Do you know the ZM head volume? I need that to make some compression ratio calculation

Great!

What do you think of the ZJ head bolt spacing?

The head bolts look like they're right but the oil passages look wrong. I've been searching for over a hour and this is all I've found.

From here: HALF WAYbf~I Rv[gGW

The bell housing bolt pattern is different you can see a pic of it here:

Here's some info I've found on solid lifter conversion in a b6 head.

I gave up searching too soon. Found the head gasket for a 07+ zy-de
reinz part #61-54045-00

Hi,

Interesting things on tapets!
I read somewhere that Kia HLA are a good alternative as they are lot lighter than miata HLAs

The KIAs HLA are from KIAs' version of the BP engine?

For the ZY block I am afraid there is only a "almost match"

I put over some head gasket to compare, all of them have an advertised bore of 79.5 to 80mm

B6 over a ZL gasket (reinz 61-52425-00 over 61-53450-00) All; belt side on the right


B6 over a ZY gasket (reinz 61-52425-00 over 61-54045-00)


For the Lubrication of the camshaft I will check on a french sport engine to see how they manage that (TU5J4 engine)
Hope there is way to just drill right into a head oil pipe

Even if the head bolts did line up I'm wondering if it'd even be worth the effort. It'd be a lot of work to convert to timing chain and properly oil/seal it. I wonder if the internal are the same and it'd be possible to use b6 pistons and rods in it. It'd be easy for us fwd guys to just swap in the whole motor and trans. It uses a variant of the f series trans that we already have in some of our cars. It'd be a little harder for rwd unless there a trans out there with that bell housing pattern.

Yeap you're right.

In my project I will swapp the not so good design from mazda B engine by a mix of part which allow me to obtain a nice R/L ratio.

So we definitly see there is no easy/cheap way to have a hi tech light alloy block.

Yup no easy way. I just checked to see if the nc miata had the correct pattern but its wrong.

Oh, the alloy Z engines didn't even share duratec's/L engines bolt patern?

Secretly I was dreaming of cutting into the Z alloy block to keep the B6 starter arangement

Do you know if it's easy to freight an engine from Japan to France? (or anywhere)
Company name? cost? Tax (my country is a leader in Tax creation...)

I would like to rebore the ZL or the B block to 81mm (i saw a 81.5mm miata from okinawa)

Can you tel me how much meat ther is between cylinders bore?

I know over here its pretty easy if you find a importer. Thats a zl-ve misslabled as a zl-de.
TorontoJDM.com - Total Japanese Domestic Motor - JDM ZL-DE PROTEGE 1.5L DOHC ENGINE & AUTOMATIC TRANSMISSION
I have no idea about over there.
Iirc the max overbore was 1.5mm and that's pushing it. You should double check that though.

Thanks, I already talk to the seller => does not sell to France

When you see that lots of Japanese perf parts seller who start to sell piston for roadster starting at 81mm not sr the max is really +1.5 (so 79.5mm) overbore.
