Triple Blowthrough Turbo

[Dat73z]

This evening I had an hr so I packed and pressed the rear end together with new OE bearings and seals. 

 

Unfortunately, one of the stubs was extremely difficult to turn when pressed on. This is a new one on me, apparently the dust shield was binding with the strut assembly. 

 

Fortunately I have a couple spare dust shields but I'll try and lightly bend this one out first before pulling all the studs out and starting over.

After disassembly it was apparent what had happened. The dust shield lip somehow caught on a couple of areas of the KW powdercoated strut assembly. After some beating with a hammer things looks better. I'll ensure there are no raised edges on the strut assembly or dust shield, throw a coat of paint on everything, and re-reassemble. 

 

Hopefully I can get it back together this next week or so, the general mechanical work is easy but time consuming. I'd like to get back into some welding and fab work.

It has been a ridiculous month and I had to take a break from the project due to working insane hours and balancing family time, but I'm back at it again. 

 

Since the last update I wrapped up the bulk of the suspension and brakes upgrades and started tearing back into the turbo aspects. 

 

I need to fully mock up the new manifolds and turbo setups into the car before we continue with the new cnc intake manifold setup so I've started tearing everything back out again. 

 

This will also allow me to refabricate my midpipe to downpipe connection.

Life got busy but I recently started working on the build again. 

 

Since the last post I've been cleaning out the garage and figuring out where things are at. 

 

All of the new suspension is on and I pulled the midpipe to begin refabrication around the new turbo setup. I also sent the vintage SK 50s out for restoration and started assembling my wheels with the 245s for more traction.

I had a couple of hrs this morning so I stripped out the old turbo setup and started mocking up the new Vband G series and wastegate. 

 

There is a lot of fabrication work ahead and it starts with mocking up all the hard parts in the car.

Had to take a break for a couple of months and go on a bunch of family trips. A few left to go but long lead-time parts are trickling back in. Had my vintage SK50s fully restored by Kyusha House as the older castings are better suited for the surge tank, they look fantastic. 

 

Once I get back in from traveling will see what it'll take to get the custom intake manifold cnc'd.

It's been a busy year but I've been making progress on the build. Since the last update I've installed a CD00A transmission, had a AL driveshaft made up, performed some retrofit modifications on the SK50s for boost/fuel control + swapped venturis, and in the final stages of the cnc intake manifold. 

 

This winter I'd like to wrap up fabrication on some new stainless fuel lines and the exhaust. If I can swing a trip down to SoCal I'll drop off the new exhaust manifold, turbo, and downpipe for inconel shielding.

Man everything looks great!  I have a Yoes oil spray bar, the one you have is HUGE in comparison!  I do have a question though......running carburetors....why a fuel setup more in line with EFI??  Surely 3-4 psi / standard carb flow is sufficient, or are you overbuilding for the future?  I don't even know HOW you found the HKS surge tank and stuff.
