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

[CrankyOldMan]

Considering that a MAF flange alone is almost $40, and tubing another $20, this makes an excellent prototype source. I don't know why I never think of ebay for cheap parts, I had the same problem with my last big school project. Specifically, I was trying to source "cheap" parts from mouser and mcmaster instead of direct from China via ebay.

I don't hesitate to buy from ebay foreign sellers. Just bought this stainless steel resonator exhaust tip from Hong Kong for only $23 with free shipping. it's gonna look really neato on the center exit.



It was only 9 days from the purchase transaction to when it arrived today in perfect condition. Pretty good for free shipping halfway around the world.

This thread makes me happy.

Tooter - would you be willing to share your dimensions for the 1ZZ TB gasket channel? I've made a rough estimate from web images and I have a gasket here to measure, but I'd like to know what your functional dimensions are.

Here's what I have so far, as well as a crude mock-up of my idea:

Sure. Glad to help out, Cranky.

I don't have the CAD data so I did physical measurements:

O ring channel inside diameter: 59mm
O ring channel outside diameter: 67mm
O ring channel width 4mm
O ring channel depth 5mm

The O rings drop right into the channels with absolutely no stress, compression, stretch, or deformation.



Cheers,

Greg

Excellent. Now to take over the world!

Actively watching this thread as I know I'll be getting a supercharger someday.

The intake arrived yesterday and appears to be decent quality. The welds aren't flawless but the bends appear to be well made. The filter also looks to be pretty solid but I don't think I'll trust the filter media. The hardware is nothing special and the coupler looks to be rubber, but again it's just a MAF tube source.

glancing through the thread, the MAF discussion caught my eye. the K&N typhoon intake's ID matches the 1ZZ TB ID, and does not get smaller at the MAF spot. they overcome this by putting a small little piece of metal in front of the MAF at an angle to fool it into thinking it's the proper diameter. (i bet if we harass 4/20 never forget, he'll take a photo of it for us!)

[tooter]

Yes. I've seen that strange metal "ramp" on a K & N Typhoon intake. It's a creative adaptation.

Ladies and gentlemen, the time has come for me to introduce you to a whole new level of Smiles Per Gallon. The throttle response is nothing short of SHOCKING. If you have a Blitz, and have the mechanical inclination, DO THIS.

Here's a quick breakdown of the parts:
1. Blitz intake upper section from an xB kit
2. 2" to 2.5" silicone reducing elbow (and 2.5" inline metal coupler)
3. 2" 90° silicone elbow
4. Cranky's homemade 1ZZ throttle body adapter (see previous posts in this thread)
5. 1ZZ throttle body
6. 2.25" to 2.5" silicone reducer
7. MAF section of cheap eBay intake (mentioned previously)
8. 2.25" silicone coupler (from eBay intake kit)
9. Intake-side cutoff from eBay intake
10. 2.25" silicone coupler (from my Injen intake kit)

You can't see the rest, but it consists of:
* Filter-side cutoff from eBay intake
* 2.25" OD to 2.5" ID adapter (made from cutoff piece of 2.5" coupler)
* Injen cone filter

Of course you need clamps for everything, but you can figure that out on your own. =)

There are other details that have to be sorted out, but I have the vacuum lines from the brake booster and fuel system (?) running to a port on the Cranky flange. The PCV tube goes through a makeshift catch can and then vents to atmosphere. The "clean air" inlet is open to the atmosphere but should really be filtered (and probably metered to maintain the OEM configuration).
