I love you. Ive been drooling over this head for a while but have not had the balls to try it, can't wait to see your results. Awesome work!

Wow. What is your day job.

Wow... I like how you see things in perspective.
Does anyone has the part no. For that triggerwheel?

I got one from a junk yard. Don't know if it fits 1.8 yet.

I actually put a z5 bottom end with a b6 top end and threw it into my festiva, I took a look at the z5's head and threw it in the garbage... i thought all z series engines were the same i geuss not! i wondered why they looked so different at the junkyard.

great bulidthread

Do you have any pictures of the zm factory exhaust manifold? is it cast or tubular?

Thank you for clearing up my oil squirter debate. In for updates on boths cars.

Sigh nithing to add but bonnnwr

So, specifically, how has fuel consumption been a factor in parts selection/engine build specs and what do you expect in mpg? I've always wanted to build some extra power into my engine, but fuel economy is a big concern of mine. Thanks.

Why is fuel economy an issue?

I'm interested in modifications for my daily driver. I can't justify high output if I can't afford my commute to work, no matter how much fun I have on the way. And I'm frugal. :facepalm:

Just wanted to confirm that the MLS head gasket from the zm-de motor will infact work on the B6 miata motor (in my configuration IE:stock valve-train and Weisco 8.5:1 pistons). Just bought one and worked perfect, pistons still don't reach the valves even with the different thickness.

This is awesome. For my SSM car, for phase 2, I've been thinking about doing a 1.6L supercharged build to drop 40 lbs of nose weight (and 40 lbs off my min weight for the class too!) This looks like some excellent stuff to use, and factory stuff too (crank trigger wheel, woot!) I'll be back with more questions later this year. :)

I thought I would post an update to what I have been working on...

First of all, last spring I co-founded a Motorsports development course at CSU Fresno. We submitted a $60,000 funding request to develop the program (i'm expecting half the $), we then procured a 91' from a local Pick-A-Part and began disassembling. The engine was removed so we could begin doing development work on the engine dyno, and a custom rotisserie was constructed so that we could stitch weld the chassis and make various modifications to the suspension.

We currently promoting the new program and looking for sponsors. Here we are setting up for a photo shoot.

Hopefully, we will see some of you at the track next summer...

At home I have been working on various engine components as well as chassis and powertrain modifications for my own car (A few parts that are currently in development I hope to have on the market sometime next year).

Here is a shot of the turbo manifold I am finishing for the ZM-DE head. The runners have been finished and the collector is being welded inside and out before the very complicated collector divider is welded in place(twin scroll turbo).

The stock oiling system on the BP/B6 is very good under most conditions. However under certain conditions the oil can migrate away from the oil pickup. Rather than installing an Accusump to assist oil flow/pressure, I thought I would first improve on the existing system.

I welded some "baffles" to the sump of the oil pan. These baffles create a shelf between the factory pan baffle in the bottom of the oil pan and the surrounding structure. This is to reduce the tendency of the oil to leave the sump under heavy breaking.

I left enough of a gap between the factory baffle and new sections that their should be little effect on oil return to the sump.

I will find some before and after photos of the modifications if they are not clear.






Now to fix the 1.8 diff housing.
I decided to fix "fracture points" the 1.8 Miata housing rather than install my RX-7 housing, because I feel that the Miata diff housing has bigger/better cooling fins. Just my opinion.

I have a Moss Motors Miata PPF Stabilizer Kit on my DD. But I thought this was a better way to stiffen the PPF. This design essentially boxes in the full length of the PPF without adding much weight.

First I took a spare PPF and cut the horizontal sections so that they follow the curved vertical section of the original. Carefully placing it close enough to not cause interference with any other components but still having enough distance between the faces for the wiring harness clips and to create a "box" structure.

I then constructed a jig to maintain PPF bolt alignment.

Then welded the two sections together.

I hope to post some updates on the engine build as soon as possible.

As usual, bloody nice work.

Badass man. Seriously good work going on here.

Makes me wanna go to csu Fresno when I transfer and join your program lol

There is always a way to improve something if the time is taken to study it. Good job.

I have a question about the similarities between a ZM and a B6. I have a 2000 Protege with the ZM and I'd like to swap a BP from my 92 Protege LX into the 2000. Do you know if the two motors are similar enough that I could easily swap the two? I know the ECU and wiring are going to be different, but I'm more concerned with actually fitting the motor in the car, mounts, etc. Are they similar enough that I could simply 'bolt in' the BP?

Thanks!
