Honestly, I think it SHOULD be allowed particularly if another vendor is brought up. I think it keeps everyone honest and transparent (not that either vendor has been dishonest) regardless of potential cat fights.

Nope, no small frame dual entry turbos. Some crazy journal bearing Mitsu turbos are divided housing (I recall a twin scroll 16G from some JDM STI model) as are some other OEM JDM STI turbos from IHI, but small-frame twin scroll is hard to find and pricey.

Doesn't come off as disrespect, marketing tactics, or anything shady; I'll vouch for you. If the rules are read to the letter of the law, we're going to have no vendors here.

I agree, it should be allowed as long as its all civilised and with respect.

If everyone were as mature and level-headed as you seem to be, there would be no issues.

For people like me, who are new to the aftermarket forced induction world, it certainly helps to know why one option is cheaper than another. Are there fewer parts? Less quality? Does it come down to economies of scale or currency variations? Is that extra two grand just profit margin? A company may claim something, but it's not always easy to tell without first-hand accounts from third parties available. (again, speaking generally. I have no reason to doubt anything AVO or AP have said)

On behalf of CA FR-S/BRZ owners (and wanna-be owners) I would like to ask you to please provide an option for the intercooler/intake piping to be that black silicone/rubber.

It looks like it can sorta pass as stock which is a godsend for us over here who have to smog frequently and where the CHP is cracking down on illegal parts.

Stock airbox utilization is brilliant and gets us halfway there to passing without removing the kit.

I really like the placement.

...not so sure about that sharp 90 degree turbo outlet pipe though. Is there any room for improvement there?

Keep up the solid work!

Just remember AVO is JDM. If the Yen continues to climb, the price of the turbo kit will adjust. You can't say no to Legacy low-mount placement though.

While we are indeed very JDM, the main factory operation is in Thailand. We moved our head staff and equipment there a while ago due to some large scale projects in that location. It keeps our pricing from going completely off the board - USD has lost about 35% or more of it's value vs. the Yen over the last few years.

We won't be using a twinscroll turbocharger. While it's a nice idea, it wouldn't be practical. A single scroll turbine will provide excellent performance, and won't add another 1k onto the price of the kit. There isn't much that can be done about that bend, tight space is tight.

Most of the hoses will be black, issues with visual inspection don't just exist in California, or even just in the USA. The FMIC will be a Aluminum bar and plate with cast aluminum endtanks - like all our other intercoolers.

We hear you,
we've had the same requests in Japan, Australia, and Singapore as well as our Californian customers. Police inspections, CARB/EPA are getting out of hand in all areas.

All intake and intercooler piping will be made of wire-reinforced Silicone, and will only be available in Black. There will be a choice between the standard air box, or an aftermarket air box. The FMIC will be available in Silver or Black.

BOV will be an optional part, with an AVO 100% recirculate (or 50/50) available, as well as other aftermarket or even OEM. The flange for the BOV will be the same as the EVO 7/8/9, for customers that want a full "OEM" look to it.

there are "twinscroll" divided entry housings available out there I've used the .78, .82, and 1.06 housings on a divided GT3076r. The results? Monster response in the mid-range, gains of 40lbft at 5000rpm, with a 10% loss up top.

It isn't worth it overall. The small turbine gets choked powering the larger compressor, and the divided housings don't flow nearly as well as their open-counterparts. For response, the twinscroll stuff is pretty good. But to be honest, I prefer the top end rush the open housings give. The engine just seems smoother and makes more power on less boost with the open housings.

Increase the size of the turbine slightly, and match the turbine inlet area? If you say the top end loses power, then part of that response gain is coming from the increased exhaust gas velocity (and thus backpressure).

Twin scroll allows more efficient exhaust wave impulse transfer to the turbine, "all else being equal" (in this case I mean how restricted the turbine is).

Paul you've answered most of my questions so far, love the option for black fmic and plumbed back BOV. I hope there is a full sleeper mode kit (all black couplings, hose clamps etc).

Do you know yet what kind of waste gate you'll be using and will there be a plumbed back option?

They're not though are they? Aussie company with international offices/factory?

I can almost guarantee you this kit will plumb the wastegate back into the exhaust as standard. 95% of kits don't have open wastegates. Have you heard open wastegated cars? OMG
