I don't have the final details or price of the upgrade. I know there will be an upgrade price for those Stage 1 owners who are looking to upgrade but as far as what that price is or what it includes/entails is still being finalized.

 

Not everyone wants twins for various reasons...

 

What are some of the reasons people dont/wouldnt want twinz?

 

I cant think of one reason people wouldnt want twins. Im not a TN hater as I loved my kit, and I like my Greddy kit as well. Id just really like to hear the answer to this one....actually only thing I can think of is that with the ST you can see the snail under the hood, thats about it.

 

Besides cosmetic reasons theres only so large a turbo you can put on each manifold in a twin kit due to space limitations. Of course with massive body work you could fit something larger but with just a fabbed up rad support Injected put a GT42 in there and could fit a Y2K or Thumper easily. Thats 1500-2400 HP on one turbo. Almost every kit on the market today (twins) has very limited upgrades available. The Greddy is a perfect example. No doubt it is the premier tuner twin turbo kit. But what happens when you want 1000 HP? An upgrade like Sharif did will get you compressors that can flow for that. But not the turbines. The only kit that comes close is SFR. If you have a single turbo and the piping is designed such that you can mount a larger unit there you swap one turbo (in the case of Turbonetics relatively quickly) and can have 500, 700, or 1000 hp without even having to modify the chassis. Of course if you are looking for 1500 HP like Injected some other measures may need to be taken but thats a different story. Some people also prefer the stronger mid-range pull and top end of a large single over a twin. In the end its personal preference. If I was building my ultimate turbo Z it would be a very large single turbo without a doubt...

 

you mention 700 and 1000hp... will that be in the Stage 3 Kit?

 

I remember reading a post a week or two ago saying there are shipping out GTK turbos mid FEB iirc. Is this still true? Have you looked into doing a group buy MIA?
Also, I know I and many others have already asked this, but it seems like things are almost done...but does anyone know an ETA of the status of Stage 2. I know its hard to say when noone knows b/c thers is still work to be done...but will it be in a month or two, or will it be more like 3-6 months?
If its going to be too long, I will have to sell my TN kit, and get a greddy. I have got to be ready by next drift season

 

**** if i had the chance to do it over again i would got twins. but i made my st bed and i have to sleep in it. i am going to push my little ST to its limit. i am pretty sure i will break 500whp. in the future if i am not happy i will get a TT kit. god know my motor will be able to handle anything i throw at it.

 

Just go twins now and save yourself the $$$$ and headache...

 

i would, but i shot my load on my motor build and the FCON.
honestly i dont need to be the fastest guy on the street, and i loved the power band of my st. if could get that same power band but in the 500whp range i will be a happy camper.
if i exhaust all options i will go TT, but i still have some research to do.

 

Good luck man...500whp is a huge step up from high 300's, that I was at.

 

thanks bro. cant wait. should be getting her back in late Feb. will post a full write up, pics, and vid.


now back on topic. wow that TN stage 2 kits sounds great.

 

No I never said that there will be a exchange. What we are highly considering is a upgrade for those existing TN kit owners. We have been working on a ideal and cost effective way of doing this for our customers which will benifit you guys better.

 

700 is stage 3, 1000 is stage 4.
That little writeup of how much more potential is in singles, as opposed to twins, was probably the biggest crock of propaganda BS in this site so far.

This is not nice to people. Some kids could actually believe it and then have their hearts broken by the TT people...

 

if you get the biggest turbo you can fit on a Z - the powerband would look like a crazy hp supra where there's nothing until it explodes with power 1500 rpms before redline. It'd be a pretty lame powerband, but would work out ok for drag racing

It's probably possible to get 1000hp out of a single turbo, but it'd be a huge turbo and probably wouldn't fit where TN's turbo currently is mounted.

 

Nah, it's the magic TN stage X kit. It will build full boost by 3300 rpm, make 1000whp at the redline and put all of the TT people into eternal shame.

Then it will cure the cancer, split the sea and turn water into wine...

 

thats the part i thought you said then ....sorry....still kinda eventually pointing to the same thing that somehting will be done for current owners

Anyways i love single turbos better personally if someone like bert says go twins and dont worry about the hasse, he i correct because there is not kit designed for those power levels of 550++whp . But it also means that it could easily change when someone design as kit for that much power and i think that will be seen sooner that later and it will be a great cause the install alone will be cheaper =] plus the better engine bay bling...

the spool time sure... 3800rpms is not like 2000 in twins, but then agian if you are racing you probably wont go under 3800rpms...

 

dont be such a hater with TN...their are not the only company that can properly design a single turbo kit out there that can perform well anyways

 

Trust me when I tell you, I have NOTHING against TN or TN products. In fact it is my opinion that SFR is the absolute best Z/G turbo solution, period (and you know what turbo's he's using)

But some of the points that were made in that write-up are on a borderline of BS. The 20G Greddy upgrade was conveniently overlooked, so was APS extreme. Noone in real life (at least to my knowledge) has maxed out either one of those, so all that we are talking at this point is theory.
And the bodywork to stuff in huge twins on the Z, is small potatoes compared with the rest of the work to build a reliable 1000whp car. But I'm guessing that in a single turbo's case the 1000hp setup will be a fully bolt-on affair, no?

I want to discuss this topic without namecalling, accusations of trolling, and people jumping out of the woodwork screaming that the thread has outlived its usefulness.

 

Since you are so confident in the abilities of the APS and Greddy 20G compressor to flow enough air for 1000 WHP please show me the data to back it up. I can tell you right now you won't be able to. The APS Extreme turbos and 20Gs can't produce that much airflow. At best the SFR turbos (which are 60-1 compressor BTW) could flow for about 58 lb/min each. Thats 116 lb/min combined flow. Roughly 1160 CRANK HP. Take away drive train loss and you are right at or slightly below 1000 WHEEL HP. Go look up a 20G compressor chart or the charts for the APS extreme turbos. The most flow you'll see from those is 40 lb/min each. And thats keeping the discussion to the compressors. The TD06 turbine section isn't going to support much more then 900-1000 HP either. With the Greddy manifolds you have no choice as thats the largest turbine that will fit on there. The APS turbine sections won't support it period.
Theres a reason why most of the REALLY high HP cars out there run single turbos. Reference the Injected car and its potential. I'm not saying you CAN'T make that kind of power with a twin turbo setup. You absolutely can. But not with the packaging/manifold constraints of this car.
