Good luck with your turbo swap lol

To earleier post:

If you can help it, you don't want anything to make contact with your turbine/compressor wheel. Options for CARB issues would be return to stock for inspection or get a gutted HFC/Cat AND ensure that your tune can pass the sniffer test (if they do that in your area). If you run a HFC/Cat, you will need to inspect it quite frequently to prevent an "unfortunate" situation!

Are you getting bored with the 7AT?

^nah..it's just I haven't found any upgrades for that tranny and I'm worried that if I continue increasing the HP that I will shred to pieces. Tons of upgrades for the manual.

You say you want more power right? but how much of that time are you really going to use that power?

You do have a point there.....well you know that HP to us is like crack to a crackhead. Once you've tried you can't get enough.

Sure it is a competitors kit but it never hurts to ask. Plus it isn't like he is going to GTM to fix or trouble shoot the kit. He would only ask a general question about whether the cats would break or not because of the turbos. Heck he doesn't even have to mention to GTM about an STS kit or not for that question. Also, I only used GTM as an example too. It doesn't have to be GTM.

Seriously though, I still wouldn't run stock cats with this setup. Or you may end up like that plane in the water.

Very true. Once you get started you want more !

STS makes the kit not anyone else. HAvibg there techs can answer questions about a part being used with there kit is more beneficial then calling stillen and gtm and asking can I run stock cats with STS turbo when they have no part of making the kit

Honestly, I'm wanting to stop somewhere around 700hp....next major upgrade is the 4.5 stroker...hopefully will have it by this time next year.

this is especially true because gtm will say "meh if it breaks apart its no big deal because it's after your turbo anyways"

that would be like asking microsoft how to fix a mac

Haha, or like asking Microsoft how to fix a PC... :stirthepot:

I can go on and on with a simple search. But I guess everyone is right and that it's "not a problem."

well as the owner of a turbo car running 18psi i can tell you for a fact that having a stainless core cat will DRASTICALLY reduce the chances of cat failure. ceramic core cats are more inexpensive but often prematurely fail in turbo cars because of the excessive heat. many people dont consider this when goin from NA to turbo but its definately something to look into

You can always find failures on the interest of you search them theres people running stock cats with the system an that's what I wanna do if my cats explode then you can say I told you so, until then I will stick with what te manufacturer tells me as well as my vendor. Thanks for the concern

Of course there will always be failure. The real question is at what rate are the failures appearing.

If a product had 95% great reviews and 5% terrible, chances are it is a great product. If a product has 50% great reviews and 50% terrible reviews, it will make you think twice.

I was only trying to show that the cats are a problem when people say they aren't. I am just looking out for the best of others that are running this kit. I mean if you truly want to stick with the cats then by all means stay with it. But just saying "not a problem" is realistically not true because nothing is perfect.

Very true. I've got about 2500 miles on mine and we looked into the turbo about 2 weeks ago and it was clean. Spun the blades and they continued to spin a few minutes after. So everything so far is working but as you said Sh't happens and if spending a few extra hundred to save thousands doesn't really sound that bad of an idea.

Very true!

Just watched the driver invitational on Speed there was a red Z with STS that I caught a glimpse of. Wish they actually showed the car

Really...do you remeber the name of the show? STS is slowly putting videos of there system out there but the only ones I seem to see are the vettes.:bs:

A few pages back a member put up some vids up they were pretty good, I think those are the only good one's that exist cause I've been trying to do the same. The show had Goldberg on it and they never even pointed out the Z so it probably won't even be worth looking up. It aired at midnight last night if that helps any.

Yeah that was my Z ...... just was hoping to see another.

Out-Perform with OUTPERFORMANCE SHOP - Your one stop auto shop for performance parts, accessories, installations, and more

here you guys go, Nismo STS shop car...... few vidoes, pics, specs, etc.... looks like they did a great job! I can't get the link to work but it's on their site, go to the showcase section at the top left corner, they have a few shop cars listed.

That's funny....did they just finish this car? My gauges are in the same place and we even used the same insert for them.:koolaidwall:

Had a couple of questions about this system, i dont know if you guys could help me out with them. Since this system is mounted under the car and takes the extra heat out of the engine bay, could it be used for racing? Also did the problems with this system for the Z ever get resolved?

What problems?

do a little reading and you will answer your own questions. :tup:

I would but 58 pages of replies is going to take a very long time

what specific problems are you refering to?

Well I seen that Mike with GTM had posted a thread of why his system is superior to a single turbo system. So I took upon myself to send a message to Rick Squires(owner/CEO) at STS to come onto this forum and explain the system to everyone. Now if they actually do this is another thing. I'm hoping to recieve a response sometime tomorrow since I sent the message late last night.

The only problems I ever had was the fact that no one had ever done a automatic STS 370z tune for the AT7 and with the computer fighting us every step of the way. The computer was always trying to reset itself back to original. That was a fail safe for the car trying to protect itself from damage.
Since almost everyone does a manual build it was something I had dropped on them. It took a bit but it's done. The guys who installed my system had to basically design a new routing system it. Vernon a STS was the one who finalized the tune for my car. At the same time I sent them a message to ask if they had tweaked it any and if so to let me know.

The problem I was refering to was that I remember someone mentioning a while ago in this thread that more research needed to be done on this system for the 370z before it was released since it wasn't working right but I'm guessing it was the problem that tower74 mentioned

A custom tune will solve that issue. You will benefit more from a custom tune. STS does send there's but custom tune will benefit the car best

That is true but they (Vernon) will help in any way. At the same time here in KC if it's not a Honda or mustang your kinda screwed. Hell the shop I had mine installed was full of mustangs....2 twin turbos being installed, a twin corvette, another single mustang...seeing a pattern here?
I know of only one other mod'd 370z in town and he was waiting to the numbers on mine before he changed from his Stillen SC to the STS.
:worship:

I seeee. Wish I could help out more.

Ohhh you will some when I call you tomorrow about the CF Amuse kit..:leghump:....Still looking might have to drive to STL to find someone. At the same time that kit will help ease my pains.

I have about 2500 miles on my STS kit, manual transmission, I haven't had any issues however it was initially tuned in Utah and when i had it re-tuned here to my elevation it did make a world of difference. STS includes the uprev license with the kit so all it costed me was the dyno time. Only problem I have is having to wait untill spring to get back behind the wheel, it can't come soon enough!

Have u talked to MKC (modified by kansas city) about tweeking the tune on your car? my roommate just had his sti done there friday and they seem to have a pretty solid business going there. when i was there he had a few 9 sec hondas (of course), 2 supras, a couple evos, an rx2... basically u name it, he tunes it. give chad up there a call and see what he can do for you

Hit me up with a text with there number. When I get back in town in mid Feb I'll hit them up. They can probably fix the warm start issues as well and maybe pick up a few more HP.

tower y not do a log and send it into uprev?

:wtf:........I don't understand what you were trying to say....
