Still think the Stillen Stage 2 is the best "out of the box" safest kit. They offer a warrenty also. TN seems to have the best customer service (due mainly in part to people on here like Mia). Saftey wise, Stillen will get you what you want. Install easily in a day. However it wont net you anywhere near 400 hp.

 

don't worry for me about the installation...

When I said it is a pain in the *** to change my cat back, I was not speaking about the installation, but more about the fact that I will have to sell my new Vibrant, I buy another one... for me this part was done last summer....

and like I said, I did a search.. and yes I know what the installation will be, but like I said, my main concern it's not the level of difficulty of the installation, but to find the safiest kit out of the box...that will not blow my engine... that why I need to know the issues like the oil selenoid and the pressure drop on the APS kit...

except for MIAPLAYA, anybody has a TN ST S1 running out of the box without any probs ? would like to have more feedback about the reflashed ecu...

 

Haven't read all the threads but avoud any FI system that doesn't come with a tuneable EMS (computer system).

I do suggest turbos over superchargers and both the APS and TN systems rock but only if oyu have a good EMS controlling the power parameters.

The reflash just sucks in the long run.

Take this from a person that knows.

 

Again 50,000 + miles WITH the turbo kit no issues...

 

any more members in your situation with the TN ST stage 1 ?

 

taurran, 12NV, ryans350zpower (I think thats his sn), keeptrying, those come to mind immediately. Unfortunately I lost track of most of the people with kits installed. Too many cars, questions, owners to remember them all.

 

I have had no issues with the TN ST and I did a self install and I am not a professional mechanic I live in Hawaii so Temp variance is not a issue for me. I would think your best performance and safety bet would be to get a:

Tuner kit, 440cc Injectors, Return Kit and a UTEC with a MAP sensor but then again if you don't have a good tuner anyone can destroy your Z with any amount of boost so if you ain't ready to dish out the cost of a new engine you may want to stay NA.

 

Both great kit for sure, delevering very good power band...

But I think, the APS ST kit will be more safer out of the box... even with a boost drop... that can only help to avoid my engine to blow...

so many people (technician who installed both kits) told me to do not go with reflash ECU...it is for sure, no safer as the APS, directly out of the box... but if I what to go with TN ST with UTEC... it seems to be another story...

for know, I will probably go with APS... or maybe I can found a used TN ST lit with the proper fuel management...

I would like to have more feedbacks about Vortech owners... Dyno plots to compare turbo vs Centrifugal blower... like Vortech or ATI... both great kit again...

 

You can get a UTEC Base Map for the TN ST Online from TurboXS

 

hey I found a guy here in my own town with a G35 with the TN ST stage 1 out of the box...! only with the reflash ECU...

Work find until is engine blow apart... BUT at 15 psi !!!!

he told me that it would never blow at 8-9 psi.... air/fuel was perfect...


SO if I can sell mt cat back and my down pipes, yes 5 will go with the aps...but if I can't, I will go with the TN ST stage 1 with reflashed ecu...

 

Stupid is as stupid does.

 

Man you are starting to be annoying!!! You are so completely paranoid about blowing your engine and yet you don't want to do any tuning just to make sure A/F are just right. Do your self a favor, APS or not go make sure have it tune the right way and shell out 300-500 for your peace of mind. If you look at the entire picture here, if you are willing to spend at least $6-7K for the kit and install what is another $300 for a basic tune to make it safe... GGEEESSS if you are that cheap then don't bother to install FI on your car.

 

It's been good for me - it's all about tires and knowing how to drive in the snow. If you have summer tires, and or don't know how to drive RWD in snow, then of course you will have problems, turbo or no turbo.

 

i guess... but I wonder if you get the kind of snow i know they get in Canada...its freaking crazy up there. If you do cool I've just never been to Kentucky in the winter...

 

Every year is different. The first year I had the Z we had an ice storm, other than chains or studs, you are not driving safely in anything, there were SUVs and 4x4s wrecked everywhere. I'm from Chicago, home of bad weather, and have never driven anything but RWD there. Personally, I don't care for the handling of FWD, prob. due to my lack of experience with it.

 

Gotcha... well in that case props to you for that. I don't know how well I could drive a car through an ice storm...

 

I never take my Z in snow... I run it until the snow start to fall...

 

Hey, do me a fever, if you don't like the disscussion here and if you don't have the mind level to discuss with us in repect... there are plenty of threads on this forum...

 

I got an 03 G35 sedan 6mt with 36k miles. In Dec. 05 I did a self install of a TN ST, at the time the car had 28k miles. the only items on the engine not "out of the box" are amsoil twin filter and a cooling mist single stage water/meth injector. I live in Rochester, NY so the temps are similar to Quebec.

I've never dynoed my car, there are no dynos in Roch. and there are no adjustments to make on the mixture except to send the ECU back for a re-reflash. if it was going to blow it would have on day one, I beat the crap out of it and it has skipped a beat.

As far as cold temps, here is the equation ( 10f ( or in your case 2c ) + cold tires + cold pavement = wheel spin in 3rd gear ) I only do it now to scare my buddy.

hope this helps

 

What was I thinking, 10f = -8c (see previous post), must be the pain killers.
