1.6 ZM going forged

Good luck on that insane brake kit. I already had the 5 lug swap in the works when biknman started parting out, otherwise I probably would have picked it up right away.
 
Front and rear brake upgrade info

Maybe as I did with the DIY turbo kit under my listing for the exhaust flanges I have for sale http://www.mazdas247.com/forum/showthread.php?t=123691052 I'll do a big wight up how the front and rear brake kit s evolved so it documented. But not snake Whichdoctor thread any longer I'll start a new one.
Good day :)

As Witchdoktor is doing by documnting the forged build of the ZM motor. If the two guys I've sold the fornt BBK kit and rear drum to disc conversion kit are willing to make some drawings(tracings) on graph paper of the brackets along with listing all the diameters and dimensions before they install them, that would allow all the the other 3gen 4x100 Protegees to build their own front BBK and rear drum to disc conversion kits. Also would need a list of either the part numbers for the Wilwood calipers and rotors or detail descriptions i.e. caliper mounting hole/tabs length, distance, and diameter then the rotor hat dimensions with the rotor overall diameter and thickness measurements. Armed with all that info one could get the brackets made at machine shop or make them yourself and then give all the info on the rotors and calipers to say good race shop like HRP WORLD, CDOC, Wilwood direct , AWR, etc and they be able to get the proper caliper rotors and some stainless brake lines with proper adapter to hook up to the stock hard lines and calipers. I had all the info but after several computer cashes and my home burning to the ground in 04 lost it all.

Thanks

No mean to jack your thread but I have a 1.5 japanese ZL-DE. Im looking to rebuild my engine and maybe forge. Will the rebuild kit for the 1.6 ZM work for me and also will I be able to go the same route as Witchdoktor with forging my engine with the miata parts or will it be too much to bore?

Jsut to clear up some stuff:
- Bore out by 0.5mm
-Bellfab Rods
-Unmodified Arias Forged Pistons or do they have to be machined?
-Will the Miata ACL race bearings work for my ZL?
-How about the Head Gasket, did that work direct for u or did you have to shim it?

no need to apologize for jacking threads. the pistons can be made to a different bore size. the question is if the ZM and ZL are the same.

first thing to find out is if the crank is the same for both the ZL and B6. if so then that's a good starting point....if that's the case you can use B6/belfab rods, B6 bearings, and if the ZM forged arias pistons aren't interchangeable with the ZL (which i think is not the case) you could contact kooldino to go about having them made.

head gasket I haven't figured out yet, cometic looked at my stock zm gasket and couldn't make one from similar templets they got.

First I'd try giving Mazdaspeed Motorsports Development a call might want to join them first and see what they can help you with then obtaining the Factory service manuals for the ZL and ZM engines for the detail information of the internals. I do know my ZM engine block has ZL cast in it in several places.
Next research the flowing links:
www.protegefaq.net the greats resource of Protege info out there
http://mazdaengines.aokforums.com/ forum for the family of Mazda engine only
http://rebuilt.com/Mazda_Engines.htm a Mazda only re-builder
http://www.mazdaclub.com/mctech.htm Mazda owner site with lots of cross reference info
http://www.imazda.com/forums/index.php Mazda forum from around the world the Aussie and Kiwi's can be a wealth of knowledge on the 323 familia
Lasley I've heard tales that it is possible to bolt a ZL variable valve timing head on to a ZM short block so the quickest way may be to get a ZM short engine block and crank then forged rods and pistons Witchdoctors has sourced and bolt on your ZL head. Or buy from a bone yard, eBay, or www.car-parts.com a piston and rod pull your motor apart make the comparaisons. That's where I was headed I got a used BP piston and rod the factory manuals next would have been to pull my block apart and make the comparisons. Untimely nobody is going have the answer you'll have figure it out yourself as Witchdoctor did for the forged internals on the ZM engine. THe ZL and ZM family is just to small to get attention from the industry even though the little engines are proven beast for boosting.

FYI I have the factory service manual for the ZM short block if you need any info or would like to purchase it. They can easly be found on eBay, Amazon, or though Mazdaspeed Motorsports Development.

Good luck,
Dave

That more for repair manual mainly but a very good resource to have. It will not give technical details on the engine like the Mazda Facorty feild service manual would. I'll try and take a picture of the cover this weekend and post it.


Found it one http://cgi.ebay.com/ebaymotors/Mazda-Protege-Engine-ZM-Service-Manual-1999-and-newer_W0QQcmdZViewItemQQ_trksidZp1638Q2em118QQcategoryZ34226QQihZ011QQitemZ320182059690QQrdZ1QQsspagenameZWD1V

Ok, so if the stroke is different, the rods are probably going to be different too.

However, the pistons that I had made for witchdoktor should work.
 
^ if any ZL person wanted to send in their rod/piston I've got the stock ZM rod/piston to compare

post up or send me a pm

IMO I think that the difference is in the crank shaft (I don't know if this word is correct in English but in Spanish is cigueal) because of the higher RPM of the engine, but that is my opinion, if someone can compare both rods and/or crank shaft please post which one is different (dunno) cause I do know that piston size is the same.
