1zz Tb on a blitz supercharger ... Any good ?

I could but sorry, I've already got my hands full making tooters. This is just one of the hobbies I do for fun in my spare time when I'm not doing my regular work.

Why not simply go to a non-CNC machinist? It's just a simple square piece of aluminium with 5 holes drilled in it. You could make your own tapered bore with a half round hand file and some sandpaper, and buy some longer metric bolts to hold everything together. I port match my flanges with a 30 year old Dremel and sandpaper...



There's another slightly more involved alternative. Cut off the existing flange with a hacksaw and have a welder weld a plate onto the casting. It's just soft aluminium. I had considered doing this on the tooters but it added an extra production step and more cost.

Since the intake on the blitz is smaller than the diameter of the 1zz TB anyway, will there be enough of a benefit to justify the labor required to make these adaptors?

There's only one way to find out for sure.

In my opinion it would work because the intake is not passive.

The supercharger is actively pumping air creating pressure in the head rather than the normally aspirated vacuum. So it's actively pulling in air through the intake casting and the throttle body. The butterfly in the throttle body is what controls the engine speed through metering the intake air. So a larger butterfly can meter more air. Even though the intake is smaller, the air will move at a higher velocity and at a higher manifold vacuum.

I'll definitely be interested to see what comes of this.

Don't hold your breath, mason.

I'll be back on the engineering campus this summer, so it would be fairly easy for me to fab up an adapter plate. I'm also going to talk to the prof. in charge of the casting equipment to see if I can learn how to use it.

I'd like to hear CTScott's take on this. He's been running a S/C for a while now.

Definitely interested with the adapter , cranky. Hook a brother up :)

Do it, Cranky.

Heck, you could do it with just a drill press, a hack saw, and a hand file.

[47_MasoN_47]

lol, I've made a few small gun parts with hand files... I can't even imagine how much work one of these would be.

[tooter]

Aluminium is soft and really easy to work with, and the supercharger adaptor is just a piece of metal with some holes in it. I'm already hacking up a manifold just to see what will happen...

[cali yaris]

^ agreed. Super easy to make an ugly one just to test it.

Agreed, though I would have a hard time using anything less than a knee mill. All of this of course pivots on me getting another 1ZZ TB, since the first one was given an autopsy to see how it goes together.

Looks like TOLMACH went and put an xB supercharger on his, and used the Tooter TB adapter to make it fit: http://www.yarisworld.com/forums/showthread.php?t=42913

Some musings in CAD. I've got a block of 6061 in mind for this, just have to make time in the shop for it...

[tooter]

While most of my concepts never make it to reality, this 1ZZ bellmouth adaptor actually did. It's 2 inches thick so there's plenty of material work with. And lots of room to drill a hole in the side to add the breather hose fitting.

$185 including shipping.

When I had one made for the experimental tooter et, I also made one extra just to see if there would be any interest in a Blitz 1ZZ Adaptor.

[CrankyOldMan]

My goal with this design is to use a 90° silicone reducing elbow (2.5" -> 2.25" or 2.0") or something of that sort to connect to the Blitz. I think that the xB intake tube would be ideal, since it's already cut and round, but convincing someone to swap could be difficult.

An adaptive slip on coupling is a good idea, Cranky. I had only thought of whacking off the throttle body base and welding on another one. Be sure to post some pics when you get it made.
