I will be parking my car for the winter in about 4 weeks. I have to get a couple of other things taken care of, and then this project will resume. I hope to have a solid update late November.
Are there that many people actually interested in the kit, or do you guys just want to see me build it? Just looking at the ST kit sales being very slow this year, I don't know how these more expensive TT kits will go. Just thinking out loud here…as R&D is time consuming and can be expensive.
Feedback here on the question in bold will be appreciated.

this +1000
this forum has more dreamers than any forum i've ever been on.
on that note, if i didn't have my big single from you already in here i would have loved to get some twin 5557's under my car.
too much time and money set aside so far to make the switch.

This is what I am thinking as well. If this kit was out tomorrow, how many people would actually want to buy it? It is hard to justify spending money on a project like this, and doing it just because people want to see it get finished.
lol, i wouldn't mind the 5557's for more midrange torque and faster spool but 500+ mid 4000 rpm range is nothing to complain about and definitely not worth the time and money of a new setup.

. You will probably see 16psi by 4000rpm, and that will get you some nice torque down low.Jeff, you would want those in a T3 configuration correct, or something like this:

The V-band housing are now available in .64a/r and .82a/r. These would be easy to fit, much easier than a T3.

i'd imagine with the high number of used kits on the market, crap economy, and severe reduction in FI interest in general for the VQ35, I doubt trying to build a TT kit will make sense financially.
can you break even on R&D if it takes you a year to sell 3 kits? Not to mention, the buyers will need aftermarket headers unless you wanna run into the same power issues, which add into the cost and complexity of the install.
low hanging TT kits have alot of compromises as well. I think people just wanna see you build one, but they would most likely not buy it unfortunately because they wont buy the low hanging kits that are already on the market.

Other than that performance will be the same.
i always get the feeling that people are expecting you to build a TT kit that will only cost a couple thousand bucks and come in way cheaper than anything else on the market.
that's just the impression i get everything I read people saying they'd buy the kit ASAP.

Heres what you do Sasha, do a group buy of 5-6 kits with money up front and make then 20% cheaper than it would be after the group buy. Once those slots are filled you at least have your backend done on the kit and can justify the expense. Need to come up with a build path on how much time and materials it will cost.
You have to keep your best interest in mind. I don't know how much it will cost you to build it, or how mucj you'll sell it for. I asked for progress because I've been interested in FI for my Z for almost 2 years now. But there in lies the problem, its been two years and i haven't done it. I've had enough money for a single turbo setup, but if something were to go wrong I'd be without my Z for a couple months if not more. If i wasn't still in school it'd be much easier. I'd like for you to finish so i have more options to weigh against the Greddy and GTM kits. However, I can't tell you that I'd even be about 25% certain on buying your kit if you finished. If you do it, do it for you with no expectations of making tons of money. Best of luck to you whatever your choice may be.

I still do this because I really enjoy it, so motivation is not an issue at all.
As far as the pricing goes, I was thinking being in the $5600-$5800 range using the GT2871R turbos for a tuner kit. Other shops for example have a kit with these turbos listed at about $6500 (also tuner kit), so the price would be an advantage. Installation would also be an advantage, especially if you already have aftermarket headers. I will more than likely finish the kit I started, and perhaps sell it to somebody with a built engine, to push it and see what it can do. These turbos on a VQ are advertised to make 800hp, so I don’t think performance will be an issue.
Then, if there are more requests, I can build them to order. It will be easy to make the jigs for the exhaust side, and IC piping should be simpler to duplicate compared to the ST kit.
Our winter here is 6 months, I need something to keep me buisy.

what was the last twin turbo kit released for non HR 350z's? the gtm kit? i dont think a lot of those have sold and lets not make this into a gtm sucks discussion. i would probably avoid building another TT kit unless you can do something that makes you stand out...similar to when everyone jumped on PowerLab's single kit when it came out because no one wanted to run the shitty turbonetics kit.
only speaking from my experience, but being a sedan, the only FI options are Greddy, GTM or Vortech (i'm leaving Stillen out cause well..their product here has a bad reputation) because of fitment issues. SFR's kit wasn't made with a sedan in mind, and when i called he wasn't sure if it would fit. Same goes with all the ST kits. I was only able to get a Greddy kit because of the deal (4K)..otherwise Id probably go with the Vortech.
I'm not sure all of the exact differences, engine-bay wise, between sedans and G coupes/Z;s, but if somehow you could make a kit that was reasonably priced, and was compatible with both sedans and Z/G coupes, you may have more options for selling. And given the projected price you're listing at, you may get more sedans jumping onto your kit...I know I would've purchased your ST tuner kit if there weren't concerns about fitting it onto a sedan.
But therein lies another problem...not many people would be willing to go without a car for a period of time to allow you to test fit and make appropriate jigs.
