1JZ E30 Vert Build Thread with Pastry filled wheels

I like the idea of brushed faces/polished lips, that’d look sweet. 

It seems so expected though..

Im really leaning towards diamond cut faces, it will add depth and dynamic to the large flat surface-

I got the wheels. Totally need to be refinished and will need new hardware. Still no clue what I will use them for.

I got some free time this morning and finally got around to making CAD models of all of the bushings Earl purchased for the E30/E36ti rear subframe, plus pedal bushings, diff spacers and diff inserts. This is great now because I have a reference if I need to make custom units. I need to drop my sub-frame and weld in camber tabs, which provides me time to upgrades the bushings that I haven't already.

Disassembly has begun again. 

I am late to working on this thing this year already as I was pretty much over dealing with it last year and haven't had an urge to really touch it. I got an itch to start working on it again after cleaning my shop, fixing the other garbage I own,  and seeing the lists of those other projects slowly shrinking compared to the length of the list for this car.

First I will list the things I want to accomplish this year for this car. I might not have it on the road, but I hope to get most of this stuff checked off.

• Higher spring rates in the rear
• ECUMasters management
• New engine harness
• Rebuild the turbo
• Z4 steering rack
• Repaint the engine bay

I have a huge list of little stuff that needs to be done too, but these are some key mile stones I want to finish. So I started last night by putting the car up on the lift and started removing the steering rack and removed the turbo. I found a place in Wisco that does turbo rebuilding and balancing- "Midwestturboconnection". I already have a rebuild kit but I do not own a turbo balancing machine. $400 estimate for a complete rebuild and balance. I hope to send it out next week. I also need to order inner tie rods and devise a plan for a new steering shaft joint.

Out of curiosity, what's the reason for the Z4 rack?

[Daggerty]

The exhaust side is what is usually in need of balancing the compressor wheel is light and is usually spot on. You can always use the sharpie method. 

The above video is how I did mine.

From what I have read, its the same as a Z3 rack ratio wise, but also adds a bit of angle if you have the room for it.

On top of that, I am using a 1JZ PS pump with a E36M3 rack and I keep having issues with leaks. (I think the pump is over powering the rack) Other threads have mentioned that the steering response is amazing and very direct, and its gearing isnt bad for street driving. I have had quite a few cars without PS and it was never an issue and I really liked it. I have a few options, but in addition to all of those, this adds simplicity to the car, and eliminates more items in the engine bay, which to me is my overall goal: Delete everything besides the motor for a very aesthetically clean engine bay.

Call me stupid, but I didn't see anywhere in that video of him balancing the Turbo shaft, so im not entirely 100% on how that works. Its only $400 including parts to have it rebuild and balanced using a specific "TURBO BALANCING MACHINE". If this was a car I didn't plan on getting buried in when im 85 years old, I would probably use magnets and shelving brackets as the gentleman and yourself did.   

[Daggerty]

He didn't show the process but basically the rig shows where the heavy spot is because that rests at the bottom then you grind off there and test again.

I know you like to do most everything yourself so I thought I'd throw it out there. Totally understandable for a real turbo.

[GunMetalGrey]

This build thread is boring

[GunMetalGrey]

So crazy enough, but a turbocharger compressor is usually balanced to a G2.5, which is pretty snug, but at work we were having balancing issues on rolls and threw a G1 on a roll. No surprise that they couldn't get it there, but it turns out we were having more issues with the roll material than the balancing itself. 
Now I'm the boring one!

[Daggerty]

I was going to say ask when the last time they had their machine calibrated, but sometimes that makes them treat you like garbage even though it's probably never been calibrated.

[GunMetalGrey]

It's our company roll shop so we wouldn't catch too much grief, but they stay pretty up on those things as it is their core business.

That's what she said...

I would be lying if I said I knew what a roll was and what you were talking about.

[GunMetalGrey]

Haha, paper machine stuff. Rolls that paper runs on, ranging from 18' in diameter

to smaller felt rolls about 12" in diameter

[Jdesign]

Now I know how you roll. That trailer is laying frame!

[Jdesign]

Have not really touched this car in awhile, I have been just really fed up with chasing the mystery boost gremlin using stock management. So to regain motivation, I just bought ECUMasters standalone EMU Black, a new lead harness for the entire engine, bluetooth adapter, and mounting bracket for the ecu. This should provide me everything I need, and I can stop messing with trying to fool the OEM management (which wasnt working).

Is that a popular system for Toyota applications? Looks fun!

Not common it the states yet, but its HUGE in the down under. For the money, and features, its the best management system I have seen, but I have no personal experience with it. I have read nothing but positives and they have a huge background of support for trouble shooting.

Got an email saying that they are done and shipping is starting today. Otherwise, not much here, just waiting on my ECU..
