The turbo should be the biggest factor. I was already planning on using a fuel return system, so I have that. It is the exactly same turbo with different internals, so there shouldn't be any modification necessary. The other two item that will make a noticeable difference in the stage II kit should be the 750 injectors which I don't plan on running due to them being hard to control near idle and the wastegate. I agree that for most people who haven't already started the part buying process like me, it would probably be wise to wait. They are releasing it in the first week of November. I think the most interesting thing to see is the GTK turbo performance!

 

You are missing some other stuff from Stage 2 like the included Spearco Water Injection system, Unichip Q and its add ons, etc.

 

I didn't know it came with the water injection system, that pretty cool! no pun intended. I plan on making my own water misting setup from a junkyard windshield sprayer pump, tubing , and diffusers. I Also have already the U-TEC and am having Turbo XS tune it for me after I finish breaking the new engine in.
It sounds like the stage II kit will be pretty nice, I'm just curious of the $.

 

I have the turbonetics kit, and will want to get the turbo upgrade w/e it is from the stage 2 onto my car. I have the bigger injectors already, a Utec,(dont have the mist sprayer thing, but dont care for it). Is turbonetics using theyre head and testing the stage 2 turbo, to be able to fit with the same piping as the stage 1 kit?? or am I gonna have to change a whole bunch of piping to do the turbo upgrade????????????????????????????????????????

 

Of course they are testing it with the current piping.

 

Your the one thats gonna need luck, simply slapping on the T66 upgrade wont get you close to 550whp. There are restrictions in the kit, I know of 1 guy, actually in VA who had this done, and he couldnt make power. HP flatlined at 5000rpm's and TQ died, it would have taken so much work with the current kit he sold it. There is much more to it than slapping on a larger turbo. Id say you'd be lucky to even hit 500whp...

 

Alberto Ive seen your posts everywhere, and envy you on your driving skills with the quarter mile. I have to ask though, what do you mean by were gonna need alot more stuff?? Im just wondering what you mean by that?? DO you think you could name some of the things you are saying we would need??????????? plz????

 

I'm curious too. I'm guessing head work...springs, cam,etc. I have been told many different figures for expected HP, so for now I will just see what I get. It's too late for me to change directions now.

 

What he means is tuning, turbine housing changes, possible turbine wheels changes, wastegate swap, etc, etc

 

Ok but alberto is saying that your gonna need more then a turbo upgrade. You just listed mods of mostly modding the turbo we have or w/e. I can see that yes the wastegate is a limit, but for some people like me who have a utec, bigger injectors, fuel return, and exhaust already I dont see what else I would need to make more then 500 whp besides a bigger turbo. You understand what Im saying I hope?right lol???

 

Exactly^^ TN is a GREAT company with exceptional customer service, my advice to peaople with a TN kit who want big (500+whp) power is to wait for TN to release stage 2. If you dont your gonna spend $1000 and basically be doing R&D work on your own, as you know and as 2 guys that I know of have found out, things dont always work as planned. SEMA is in 2 months, wait for the kit and enjoy it then, dont jump into customizing a stage 1 kit, its not going to work and you wont be happy-it takes more than a snail to make a turbo system work up to its ability. Im sure yuo have seen D350z's "T66" TN car, it makes 525whp on a dyno that reads high, on a dynojet he'd likely be at high 400's whp, and IMO and I mean no offense to him the powerband is awful. No power under 4500rpm's and no TQ above 5000rpm's, wont make for a very good setup IMO-but what do I know....

MIA or Sharif can chime in as I dont recall the specific restriction in the exhaust with the T66 set-up. Sharif found out the T66 and 60-1 share the same turbine/exhaust housing-some$hit? I could be off, but it was a limiting factor in making power with a specific T66 TN set up and it wasnt something that was going to make power even with a high flow exhaust/utec/fuel return-the restriction was in the exhaust somehwere, and was so bad that it wouldnt allow the T66 to make power to our cars peak.

 

Thats the answer I was looking for lol you always come through some how. I wish I was closer to you to be able to see you run at a track. Trust me I understand what you were getting it, just wasnt sure. I AGREE TOTALLY that people should wait and let turbonetics do the r&d. Im just worried you know b/c it was a restriction, b/c I remember that too and its gonna suck b/c it might involve changing alot of piping to get the higher HP numbers out of a TN kit. Your the man alberto, always inspiring, confident words come from you lol.

 

I'm really glad we had this discussion! I am definately going to be waiting. Thanks for your help alberto! I just got the call that my engine is ready and hopefully should be getting it Monday! I am going to run the normal setup for now after the breakin period until SEMA. I work in la plata MD, and go to MIR once in a while with some friends. We'll have to meet up. Just let me know. Thanks again!

 

No problem, we can def meet up. What cams are you running?

 

Im actually running stock cams b/c I could never make up my mind. I didnt want to buy the jwt cams b/c they were more made for N/A application. I have heard that they just came out with an application for F/I, so Ill probs check that out. What are you running, maybe nismo ??

 

Actually the T66 and the 60-1 can use whatever turbine wheel and housing combination you want. The key is in picking the PERFECT turbine wheel and housing for the type of compressor you are running, amount of power you want to make, and amount of exhaust gas that will be produced. That kind of R&D takes time. As Alberto said Stage 2 will be worth the wait.

 

What are you talking about? I already told you the same thing at the end of the last page.

I've seen nut hugging before, but damn...

There are not only changes to turbo and wastegate that will need to be made, but also changes to key points in piping configuration to promote flow. As stated, it's been done, and without the best results. Saying you can't wait two months for a properly R&D'd kit is ludicrous.

 

i highly doubt a selling product will be ready b4 sema i hope b/c thats when im getting a new kit when the new stuff is out i was tired of 400hp

 

taurran go hug your own nuts, you didnt answer my question so thats why I asked it. You suggested that I was just talking bout the turbo kit itself, and I wasnt. I was asking about supporting mods AS WELL as the turbo kit itself. Dont go getting smart when your not. Main thing thats sux is that its probs gonna end up costing more money to mod a stage 1 kit to get more power. Once you have to start modding the pipes, thats it right there alone it starts to get pricey b/c the install is gonna kill you. Your going to have to take off your whole turbo kit probably and replace all the original pipes.

 

Um no you aren't. At most you would have to replace two pipes. And if you can't replace them without removing the rest of the kit you have no business near a car.
