think it would be very helpfull to hear from our members who have an APS TT kit installed on the Z. as a Z owner, i am thinking going FI, however i narrowed it down to APS TT. But i would like to know what the owners of the APS TT think of it.

what is your general opinion on the kit?
Have you had any bad experience with it?
Do you feel that the kit is good for a daily driver?
Do you like the results?
what would you recommend to be changed?
what would you recommend to be added?
Would you recommend it to others?

if you feel you need to give another opinion based on a different question than the above, please feel free.

what is your general opinion on the kit?

a true bolt on kit.. has all the pieces you need right out of the box

Have you had any bad experience with it?

nope

Do you feel that the kit is good for a daily driver?

perfect for a daily driver, once installed correctly you won't have to touch it

Do you like the results?

fantastic response, little to no lag noticable. great results

what would you recommend to be changed?

nothing on the kit if you are going to stay below 400hp

what would you recommend to be added?

the following if you are really going to get on it, upgraded radiator and oil cooler and clutch (JWT or Nismo will do fine for less than 400hp), true dual exhaust and 1 step colder plugs

Would you recommend it to others?

yes, this is the way the Z should have come from the factory


Overall a great package, you could drop this kit on a pure stock Z and not need a single item that is not included in the box. Everything else either will increase performance or improve the stock components to handle the power heat

 

what is your general opinion on the kit? Near stock looking fitment, excellent performance.
Have you had any bad experience with it? Smoking turbos, but my installer remedied that.
Do you feel that the kit is good for a daily driver? It is my daily driver.
Do you like the results? 462whp 445ft.trq w/ 18000+ miles after turbo, you tell me.
what would you recommend to be changed? Need tires, replace all fluids all of them, clutch obviously.
what would you recommend to be added? oil cooler, thermostat, radiator, guages. Things that would help, vented hood, diff cooler, maybe automatic gear ratios.
Would you recommend it to others? yeah if you have the money to play it definitely pays.

 

what is your general opinion on the kit?

I really like the quality of the kit. Looking under the hood it looks very nice. As it was said earlier in the thread...stock looking fitment.

Have you had any bad experience with it?

Not really in the three weeks I've beat on it I do seem to be burning some oil...not like smoking or anything. I was down a quart of oil after my first thousand miles after install. I am monitoring that situation know with my installer.

Do you feel that the kit is good for a daily driver?

It is not my daily driver. I have to commute quite a distance so I bought a Civic for my DD. I personally would have a beater car as a back up before doing such a major mod to any car with any kit.

Do you like the results?

I just out of my car from a drive on a cool night here in Northern Cali...my car loves that cold air for boost! What a rush. I blended some 109 octane gas with our crap California 91 to make 95 octane. Before I added the 91 my car seemed to respond much better and still does now with 95 octane. Don't know if that is possible since the tune of course is the same.
467whp 420 lbs. TQ

what would you recommend to be changed?

There are some things my installer mentioned to eliminate some of the insall issues people are running into revolving around smoking turbos / oil drainage. As far as on the car after the TT goes in: tires and clutch. You might get away with stock clutch for a while if your around 400 rwhp. I have Toyo 245/35 in the front and 285/35 in the rear on my stock 18" rims. My car is a total sleeper with it's stock appearance (sounds like an animal though). Most good installers for the kit can fab you a custom true dual 3" exhaust. This was cheaper than getting a "name brand" exhaust.

what would you recommend to be added?

You can see it in my sig. My installer recommended an oil temp gauge and of course a boost gauge. If your going with the kit out of the box these two guages should be the only required additions.

Would you recommend it to others?

Yes..if you have already decided to F.I. your Z. There is risk but you can eliminate a good deal of it by having a quaility installer and of course quality kit ( APS TT). I really love this car now. The Z is my first sports car and I could not believe how much I missed my car when it was under the knife for the APS TT install. NOW I catch myself at work fantasizing about driving the dam car and racing. It really is a treat. I will see how reliable my car is. I trustthe quality shop who did my work however I am running more power than just an out of the box APS TT. So time will tell...so far so good.

 

The response is due to what i think is the advanced timing in our car. When you blend which i do religously, the car knows this due to knock sensor and advances the timing. Thats why i think it rips really well at night especially with 100 oct mix.

Can you guys notice the sound. When i have 91 my car is noticeably raspier and rougher to redline and with 100 mix it swings to redline much easier.

 

doesnt that hurt your block in the long run since its tued to a 93 octane map? Doesnt it hurt to just higher the octane without a tune?

 

100 octane results in slightly higher EGT's but if the timing is properly mapped, which I am sure it is, it's perfectly safe to run 100 octane from time to time without a retune.

 

The higher octance burns more evenly and more completely in the cylinder. This in effect aids the combustion cycle by not leaving unburnt fuel which is why it decreases threat of detonation. Detonation being the major enemy of an F.I. motor as well as any motor. So the higher octane provides more safety in reality and gives "insurance" to your tune.. I'm new to F.I. so I am still learning how to listen for detonation which can happen with one bad tank of gas. The colder weather aids in less chance of detonation but now boost spikes need to be monitored. Now if you retuned for more power with higher boost pressure..you increase the chance of detonation, thus needing higher quality fuel and attention paid to the timing of the car. So it's kinda the opposite of your question- If you use lower octane fuel without retuning you will hurt the block with detonation.

 

sweet thanx sharif and calimarc.

 

what is your general opinion on the kit?

Very happy with it.
Have you had any bad experience with it?

no
Do you feel that the kit is good for a daily driver?

I guess it could be, but I wouldn't modify a car to this extent if I didn't have a backup car. The car is daily driveable, but I don't drive it all the time simply because I see no point in racking up miles on my trip to and from work where I can't have fun with the car anyway. There are many issues that can creep up with a car that you add forced induction to, so if it's your only car I would have a really hard time telling you that a turbo kit is a good idea.

Do you like the results?

Love the results...over 400whp and 11 second 1/4 miles, plus the car drives nearly like stock when it's out of boost. It's smooth, quiet, and very liveable.

what would you recommend to be changed?

A more user-end friendly engine management
user operated boost controller
different wastegate actuator options

what would you recommend to be added?

You'll need guages, upgraded clutch, better brakes, and some new bigger, sticker rubber to put the power down.

[bWould you recommend it to others?[/b]

Definitely. This setup hasn't let me down yet.

 

what is your general opinion on the kit?

It makes the car come alive and its a whole lot of fun! Why can't Nissan make it like this out of the box though?

Have you had any bad experience with it?

Not yet...

Do you feel that the kit is good for a daily driver?

AS long as you keep and eye on maintenance and upkeep it should be fine.


Do you like the results?

Anything over 400WHP makes it worth it

what would you recommend to be changed?

Fatter Tires (done) Colder plugs (done) Upgraded clutch/flywheel (done)


what would you recommend to be added?

How about a CARB Cert? ( think it will or wont happen?)

Ok well then throw a few gauges on (done)


Would you recommend it to others?

Well if you want to put your car into supercar type power without the expense of a supercar..why not?

 

I would expect this from someone who has "serious" personal problems in their life.

 

What do you mean RedBird???

 

Unfortunately, BriGuyMax's entire post was not picked up as a quote. when I made my post, see the end of his post.

 

Ahhhhhhh....you produced that famous quote. I'm sure it was taken out of context. Really no offense but I laughed my azz off when I read that. Of course I don't know you....but it is funny.

Peace

 

Maybe so, but I asked this because I have an automatic, and I don't know if there would be a difference between an AT and MT when it comes down to the amount of noise coming from the JWT flywheel and clutch, Im no mechanic, but Im just trying to find out these things from people who seem to be more knowledgeable at these things than I am.

 

what is your general opinion on the kit?

Wow, Love it, Couldn't be better

Have you had any bad experience with it?

Nope None...

Do you feel that the kit is good for a daily driver?

Yes I do, but of course this all has to do with TUNING and REAL USAGE SETUP, some of you know me already, and know that I can't say enough about KNOWLEDGEABLE and TRUSTWORTHY TUNING.

Tuning is NOT simply adjusting the boost & timing to get a A/F Ratio you are comfortable with.

My car is a Daily Driver, I Track It, I drag it, and I beat the hell out of it frequently. My car was tuned and setup for this and I am somewhere in the 20K miles on it since install and trust me, hardly any of it has been easy on the car.

Do you like the results?

Absolutely!

what would you recommend to be changed?

Oil Feed Connection May need to be jetted to better resolve
the smoking turbo issue.

Some of the hoses provided with the kit are not necessarily
the best fit to/from intercooler when "comfort" is considered,
(yes the included hoses reach).

what would you recommend to be added?

Oil Catch can should be a requirement and not an option.

Would you recommend it to others?

I do every time someone asks me, specially just after I kill'em

 

Hi Alpine,

Sounds like you are sold on the set-up. I have a questions on the APS TT, how low in the RPM band do you notice the power start to kick in? I was sold on the S/C for the low end boost, but it sounds like the APS TT boosts pretty low too.

Since I live in Denver, S/C doesn't seem like a viable option(only get 265 rhwp) with a Stillen Stage 3 Kit so I will have to go Turbo and wondered if the TT system was worth the extra money.

Thanks

 

SC is a joke for low end power. Look at my dyno chart and you tell me if there is any lag in power. boost is near instant:

 

StarChecker,

Let me tell you what, I was a few days away from getting a S/C myself.

There's nothing wrong with a S/C except for the limits you start with, and the cost to raise those limits.

I also have personal dislike for the concept of parastic power. Everyone will
jump in and say "yea that's the worst" and other's will kill you for even thinking it, but that is my opinion. And I know someone will jump in here and
tell me how awesome the S/C is with 500RWHP and 500TRQ and never had a problem... All of that is good.....

Anyways, if you would like to save some money, and get 85% of what a twin turbo does for you, I can easily recommend the Single Turbo from APS, it is basically the same on the top end but nothing will compare with a twin turbo as far as initial lag, initial kick in the pants, and overall power spectrum.

I've got boost builing between 2500-3000, full boost is available anytime after 3K and it's all the way through red line, all the way through all of 5th, and when you break 6th it's stil there, but you've gotten used to the sensation by then.

Bouncing off the rev limiter in 5th is always nice... and I've gone through 6th, since turbos, only a couple times.... it's kinda scary due to the distance you've traveled before you reach that speed when your boosting....

But with this kit, or any other FI solution, it's all about Tuning... Have it tuned for the way you are going to use it!
