i hope you get this resolved!! a TB that works really well for very little money is the ebay "ku engineering" , its a blue anodized q45 based tb made by 5 year olds in china and it works absurdly well.. especially since its ~75$
a cpl questions for you
-which cams are those? what did you set the cam gears to?
-why is the catch can breather in the same intake box as the filter? it seems it could pull in some oil vapors into the intake
-did you do any internal porting to the 1.06 hsg?
we dont have "Dixie" beer here

I can answer this one. Originally it was a closed system that went from the stock valve cover vent to the can and back to the port on the intake tube. The "can" was put inside the airbox at that time because of space considerations. Mainly because the ignition system was were I would normally place the "can". We later decided to increase crank ventallation by adding a second port in the vc, enlarging them both and adding a vent. Since the "can" was already there, I just converted it to a vented system as opposed to closed. The baffles and packing in the "can" separate any oil from the crank case vapor exhausting out of the vent. I'd be very surprised if this would ever pose a problem.
Honestly its pretty crude...along with needing internal port work, there are no recess's around the bolts going to the manifold, can make getting a wrench or socket on it very frustrating unless you modify the housing. Also any water fittings and oil drain line will be very tight.
The cams are a custom CNC machined billet. They are a proprietary profile, but give 272 deg advertised duration and 12.3mm lift. They are designed to take full advantage of this particular head. Despite their aggressive character, I have them ticking over neatly with the factory ECU.
I considered taking a Dremel to the inside of the 1.06 housing, but after giving it a look, I don't think it would have accomplished much.
As for Ku's TB, if I could be assured that it didn't leak, I'd actually consider it. Anything is better than the situation I am dealing with now. I just don't like the thought of having to remove this manifold, and sending it back to Tom to be reflanged. That just doesn't seem fair to either of us. Hypertune promised a replacement 2 months ago and now isn't returning my email. If the new TB isn't there and waiting when I return home this weekend, I will consider the alternatives.
If I have to pull that manifold, you'll see about 6 Dixies sitting under the hood ...
cams sound exciting, try and play around with some advance on the intake cam and retard on the exh...
i've sent numerous turbine housings for some projects we build to Dave @ headgames for cleanup/porting and after doing evodan's 1.06 he said those housings need more cleanup work than any thing else we've ever sent him. obviously they work great as-cast, but one would assume the gains would be improved through porting, particularly with the more aggressive hta compressor wheel
We run the Ku Engineering TB on our drift car, which is abused thoroughly (landed 3rd place at D1GP, top american finisher) we tack welded the tb screws for good luck, but beyond that it works well and has not leaked one bit. Another friend runs one on his consistent 9 sec civic and hasnt had any problems (screen name InDub on evoM), although im sure you really dont want to pull the plenum and weld another flange...

Yeah "Ku Engineering" has a nice looking intake manifold as well that looks like the HKS Kansai replica. I'd be interested in seeing some tests done with that since it appears to be the same other than it not being cast. That's pretty sweet that their cheap TB doesn't leak.
Hope you get it all worked out Ted. You'd think with the price you pay for the Hypertune products, you would get better customer service. Good luck.

The update is that as I suspected, the replacement TB that Hypertune sent me to replace the first one that leaked like a sieve was unusable for the reason I suspected - the return spring was too heavy to allow full travel. The replacement for that one never arrived, and Hypertune stopped answering my emails.
I successfully performed surgery to swap springs, and so now we'll see if that finally gives me a usable throttle body. This has been a needlessly frustrating experience.

Ted, have you thought about switching to something else if this doesnt work, if so, what?

I would figure with the amount of people watching your thread, that Hypertune would step up to the plate on this. It looks like they've lost the faith of a lot of potential customers here to say the least. Good luck Ted.
