The only reliability issue I've had with the engine is the intake valve seats. (And Im not alone there). And that would have happened 100 shy of where I actually was last year too.

I am excited about the new setup and am somewhat confident the intake valve issue is fixed.

My car's power delivery is very easy to manage. That's my setups goal. I wasn't interested at all in peak power when it was designed. It was manageable power delivery, usable power band and transient throttle reaponse.

I agree, your power delivery was great, especially with the traction control. Similar to mine once I got the wastegate issues fixed, you just have more of it.

Reliability. What do you think it would do on a road course doing 20 minute sessions with full throttle pulls through 3 of the top gears every minute or so? My experience has been that type of use kills stuff fast when its turned up that much and you are running a lot more boost than me.

I've reused the same intake valves since I first built it to 2.0 L like 9 years ago. I'm on the third bottom end rebuild and second head. I burned exhaust valves twice. I think if I only did autocross with it however I probably would still be on the first build.

A few pictures of the winter progress.

Upgrading the lines does you no good if you still have 5/16ths hard line in the tank....

And I decided to move a little weight around inside the car.......this picture stresses me the hell out.

Are you leaving the fuel pump wiring connector stock?

What are you running for a filter?

That charger made me think of

https://www.miataturbo.net/attachmen...ine=1449422540

:D (sorry of it have been referenced before)

What blower/what size is that?

lol at all the stupid comments on fb. "I'll take your megasquirt" "Are you building an Exocet" "I'll take your wing" :rofl:

Um no bitch. The engine is out for rebuild and I'm making it better. :party:

Got the ABS brick relocated, mounted and re-wired. Now just to build the new lines.

https://www.miataturbo.net/attachmen...ine=1449453886

Also if you have an old 1.6L SC that you don't need any more, I know someone who runs one that might be interested in buying a spare. :)

Got back from PRI on Sunday and had a few boxes waiting for me.

:Spent some time with the ACL guys at PRI. Explained my frustration with bearing supply in a very polite way and complimented their product by saying that even though I could have switched product lines, I wanted to stick with theirs.........apparently flattery get's you everywhere.

https://www.miataturbo.net/attachmen...ine=1450179709

At PRI I attended several informative seminars on engine bearings, engine coatings, engine building, cam timing and cylinder pressure.

Also...I think I have found the new blower setup for the car. A friend of mine snapped this picture of me looking at this setup just a little too hard.

https://www.miataturbo.net/attachmen...ine=1450179709

I also finished the ABS brick relocation project. All the new lines are made, in the car and bleed.

Can you not run a brake bias valve in SSM? Also, could you shed some light on the fittings you used in your distribution block. I have never seen anyone run SS flex line for brakes before but it seems like a great option considering how much trouble I have had with hard lines.

Yes you can run a bias valve in SSM. The entire braking system is free and urestricted other than the requirement that the rotor friction surface be metallic unless the car came with carbon brakes from the factory.

The lines are ss-braided ptfe lines with compression fittings. Stuff is available at any major parts house. Make sure you use the same brand hose and fittings. A few folks have has issues when trying to mix and match. All the lines have -3an ends and then a -3an to 10 x 1.0 inverted flare adapter. Total cost of the lines and fittings was around $300. I did all the brake lines and built a clutch line that goes straight from the master to the slave cyl.

Moving the brick took @ 12lbs off the nose and up high, opened up some much needed real estate under the hood and between the weight of the factory ABS bracket, weight of the new lines vs factory lines and the @5 feet of wire removed from the ABS harness. Took a total of @7 lbs off the car. Win, win, win, win.

What year ABS is that? I ended up with an 2004 system out of an MSM in my car. I like it, but it's still in the stock location.

Thanks, here's :likecat: 69 for you. :giggle:

Rotor friction surface has to be ferrous, not just metallic. So its got to be iron or steel. No such luck using those pimptastic super lightweight Ti rotors for wilwood.

Fuel pulse damper arrived today. I think that was the last piece of the new fuel system.

When aluminum Kirkey's are just too heavy!!!

https://www.miataturbo.net/attachmen...ine=1454724460

These showed up today....they are so light I giggle every time I pick them up. I had to bolt them down before they flew away.

Needs carbon fiber bolts. Normal bolts are too heavy.

:giggle:

Here are some more pictures of the off-season progress on the car. We designed an adapter in solidworks which would allow the new blower to mount to the "old" manifold. Once we had it all laid out we used the 3d printer to make a "prototype" and mocked everything up. Made a few tweaks then loaded the program in the CNC machine and made the final parts.

As part of the MASSIVE weight "program" for the winter...I went away from the belt driver PS pump to the Toyota MR2 electric pump in the trunk. With the new control arms, ABS brick relocation, PS and a few other projects we will have moved almost 50lbs off the nose of the car. That 50lbs along with a few other LBS we have removed with the seats and a few other projects....we will have a total of 70lbs of new weight in the trunk...That was MUCH needed as the F/R bias of the car last year was like 57/43

And just as a teaser.......here is one of the new seats on the digital scale :)

https://www.miataturbo.net/attachmen...ine=1454768039

Required to run a full-size seat on both sides, or can you cut the passenger side down?

What's the min weight?

When does the BP get thrown out. That's great ta be a big chunk of nose weight.

Are you using the super lightweight control arms V8R has just come out with? They aren't on their website except for a placeholder but I think they are aluminum and the name is X-treme or something? Being on the bleeding edge I figured you would have them.

They are supposed to be here in a couple weeks. They are supposed to save 12 lbs off the nose. They don't have the aluminum ones for the rear yet but I will be using their "pro series" rears

2057lbs is my min. And I'm not getting rid of the BP.

Yea. We have to run a full size, fully upholstered seat on both sides.

Time to bust out the spray glue and an old bed sheet to meet the upholstery rule.

https://www.miataturbo.net/attachmen...ine=1454809236

Annnnd there is the Power Steering pump mounted. That was an easier project than I thought it was going to be.

Was the electric PS pump a net weight savings or a f/r balance improvement?

Yes

The MR2 pump is under 6 pounds? I know the volvo pump isnt, heck the hydraulic hose front to back is like 5 pounds once you put ps fluid in it. I know I did mine just for getting weight off the nose and because my huge turbo was in the way of the stock one.

By the time you factor in the weight of the pump, the bracket, the fasteners, the PS cooler and the stock lines. Yes it is. The 10' braided SS line is actually lighter than the 2ft long stock hose.

Eric, I'm sure you have numbers. What's the weight of each system with fluid? As mentioned you have longer lines, so they might hold more fluid weight than the factory lines?

First diagnostic checks of Power steering pump, relocated ABS and re wired fans, ignition harness and fuel pumps worked flawlessly.

Pretty stoked I don't have to spend weeks going back through all that mess.

Started the day like this

Is that a soft blow hammer?

I see something in one of those pics that I despised the last time I built an engine (way over ten years ago). Manual ring filer, I still fucking hate you!

who did you have coat the pistons?

There is a STRONG hint who did it in a couple of the pictures.

:likecat: just checking

How does their price and turn around compare to swaintech? I've got a bunch of things that will get coated this year.

I really can't compare them to Swain tech as I have never used Swain Tech. But I met the guys from Calico at PRI and was very impressed.

If you are interested, call their office and ask for Brad. He will work you up a quote. I had a TON of stuff coated, valves, wrist pins, 2 sets of bearings, pistons, etc etc etc. So it's hard to remember what each part was...I just remember the total.

Turn around on every thing other than the DLC coating was just 2 or 3 days. The DLC is about 14 days.

Your last pistons you had polished pretty heavily. Why the change in approach on this build?

The conversations I had with the guys from Calico sold me on the benefits. We will see in a short time if it was the right choice or not.

did you do dlc on the intake valves?

I gotta get back...in...time

https://www.miataturbo.net/attachmen...ine=1455577252

I wanted to. I sent them the valves and their engineering department determined that tge DLC process isn't compatible with the black nitride treatment on the valves from the factory.

You could blast the meloniting off and have the face reground then get the dlc.

Not according to Calico's engineers. They kept referring to "outgassing" and I felt like I was watching Armageddon.

I guess your best bet if you want the ground face to get any kind of coating would be to blast and re-grind them and send them to a shop that does QPQ Melonite.

Making steady Progress with the new blower.

Then I decided I want to be like Pat:

:laugh:
well played

I have to say, two turbos work better than two superchargers.

Looking good though. What changes have you made on the SC setup?

Also since you seem to have a thing for light weight and reliable, you might consider replacing your t-bolts with ABA hose clamps. They work better, and are lighter. I've run 40 PSI on my ABA hose clamps so far, no boost leaks, no blown off pipes.

There are 3 Superchargers in that picture.

rotfl, I missed the 3rd one until you said something.

Not pleased until 1 supercharger/cylinder. :likecat:

+1

:bigtu:

Tonight when I get home, I have got to clean the trailer out and getthe car loaded up to head to Atlanta tomorrow. I have a stack of pulleys and a power goal that I think is within reach......we should know if all the work was worth it by the end of the day.
