Thanks to Dneg/Foamy, the head is now off getting inspected for damage and a basic rebuild.
Next step is to finish removing the block from the engine bay so I can strip it down and hone the block.

Big post, many photos, such update, wow.
 
Bought another motor for the SlushDub since it came up cheap.

 
Came with LSD gearbox too.

 
Then made a trip back to QLD.

 
Found some spare wheels for the drift session.

 
Loaded up the TrackDub.

 
Then ran into a spot of bother.





 
Had some laser cut flanges for the 1MZ/3MZ arrive in the mail.

 
Holes need drilled out 0.5mm larger.


 
While I'm lacking a workshop, it means going back to the basics to some projects.



 
With the stock chamber cut off, it will allow a newly shaped chamber of similar or larger volume to be welded in, but in a better shape to allow the twinscrew supercharger to move 25mm close to the head.

 
These studs stop the twinscrew from getting much close to the head even with a modified mount, so they have to come out.

 
However some factory 4AGZE flywheel bolts fit as great replacements.

 
And when it cooled of, I decided to wash the dust off the TrackDub.




 
And some free advertisement for Steve.

Big thanks to Steve and Iain for helping me get the damaged trailer home on the weekend. What started out as a simple pick up and run job turned into a 13hr day. Couldn't had done it without you blokes around to help!

IT was a great experience! My god I was exhausted then backed it up with a day at Wakefield!

Geebus, what happen on the trip? 

 

Back to Toyota's...
Bit more tinkering on the twinscrew tonight in an attempt to bed down on how it's going back together for Nationals. Finished a half assed mount for the supercharger top. Needs some plate welded onto the angle to reach the remaining 3 holes, however I might just make this part out of some 150x100x10 steel instead as it's easy to source and I can weld/cut it with ease.


I rotated the position of the bypass valve to provide more space on the head side for the intake manifold.


Some kind of intake manifold to be made in here. Will probably be ****, but I just want to get this running ASAP and it can't be any worse then the stock setup.


Lower supercharger mount modified to suit new position.


Quick layout of the belt position, however I might need to add an idler between the supercharger and water pump to provide more belt wrap between the two. Also added the oil return hose, just need to weld in a AN-10 fitting into the sump to accept it.


Oil feed for the supercharger, need to get a hose made up to this then plumb it into a spare port on the thermostatic oil cooler plate.


Fitted aforementioned thermostatic oil cooler plate.


Need to do a quick test fit into the engine bay tomorrow to see how everything sits and where I will locate the W2A core.

Another quick update.
Started making Sh!tManifold v1.0 to get this show on the road.
 
Bought a $30 vice from Bunnings and taped some random bits of alloy to it to make it into a pipe crushing machine.

 
Bought some 3" aluminium tubing and crushed it over a 36mm pine plug to form the plenum chamber.

 
Brings it down to below the 45mm gap I have between the chopped 4AGZE manifold and the twinscrew unit.

 
A quick dummy fit shows it will do the job.

 
Quick dummy up of the intercooler placement and intake pipe paths.

 
Had a friend weld some plate to the chopped 4AGZE manifold. Each hole is for the cylinder runners and needs ported out to suit.

 
First port roughed out.

 
Few lumpy bits to smooth out.

 
It's nothing special, but it will work.

 
I'm working with minimal tools at the moment, just a rotary file bit in my dewalt drill

 
The plate welded to the manifold will be trimmed to size once the porting has been completed.

 
Then a section of the plenum will be removed to match the trimmed plate on the manifold.

 
Then the two halves will be welded together forming a sealed manifold/plenum.

 
Quick fitment to the motor to have a look.

 
Add the plenum.

 
Another angle.

 
Till next time...

Wtf happen to your drill?

It's a 10+year old 2 speed Dewalt that I picked up at a yard sale for $5. Battery was knackered and I have oodles of Lithium Polymer batteries laying around, so I converted it to run off them. Normally the battery is ziptied to the base of the drill to make it mobile, but I had just swapped batteries and hadn't put it back on :P
