If you were getting them for the same price each, which kit would you choose, the GReddy TT kit, or the APS Single Turbo Kit? Why?

 

i'd get the aps st simply because it's ready to be slapped on right out of the box, whereas with the greddy tt you will need additional parts in order to be running safely.

 

If you want my opinion, unless you are some kind of monster tuner or something, you don't want anything to do with Greddy.

I think that Greddy makes "ok" products, but in regards to quality, without having to concern yourself with all kinds of issues and mixing and matching Greddy and other components to give yourself a overall better product you should go with the APS ST.

The next thing on your list of concerns should be installation/tuning.

There is no "slapping" this kit on and running with it, and that actually goes for any kit.

You want to make sure you have an experienced installer available, and I know that "experienced" with this particular product may be limited in itself, however an experienced tuner is absolutely required.

The kit will do what it's told to do. The kit does not know what you intend to do with it, or what other modifications have been done to the motor, drivetrain, electronics and exhaust most importantly exhaust.

Another thing the kit does not know, is how you intend to drive the car, and under what conditions... this is what you and your tuner have to determine in order to deliver you the best performance and safety combined to YOU uniquely....

If you are in the los angeles area, and/or you are capable of getting your car to los angeles, I would highly recommend Brainstorm Performance, so long as Ed is still the Master Tech and Top Tuner is on staff.

I can tell you this after 20K hard miles, installed in Nov '04, the car is a daily driver, tracked, dragged, and flogged regularly through ALL WEATHER CONDITIONS including 110+ ambient outside temperature where the integrated thermometer shows 100,110,115,120!

Did I slow down? Just a little...

Did I not jump on it back to back? Maybe not as many times in a row....

The APS TT kit rocks, as does my installer, and the only difference between the TT and the ST is just a little longer delay on boost and easliy 5K less after you install and customize at TT.

Good Luck!

 

My guess is that people on this forum will be bias, so I might as well be too.

I have the APS TT and have no problems just like Alpine. I have had it on now for a year and the kit is complete. You don't have to do anything more (maybe the exhaust, but not required).
I think Greddy makes great products too, yet be prepared to get addition parts to make it run safe.

 

so the single turbo may be better for me because i dont plan on upgrading suspension. i dont want my tires spinning for the first few gears. but what would be the 0-60/1/4 mile differences between the aps single turbo and twin turbo.

 

Man thats a tough one! Everything for the Greddy can be bought to make it safe. Do a search on the APS ST and it also has its share of problems. The problem with teh ST is there is a lot of guessing as of right now when it comes to its problems. No guessing for the Greddy everyone knows what to address.

 

I know you didn't ask, but I'm just curious, is there a reason why you're not considering other kits (like the Turbonetics S/T? ). It's always interesting to see what people base their decisions on in purchases such as this, so I was just curious. The Turbonetics S/T tuner kit would be my choice if I had it to do all over again.

 

why not s/c? there's an article around that compared these kit and the vortech actually faired pretty well........ do a search on the FI forum..... read about it..... interesting things....

 

I had the APS ST kit and if I had to do it all over again I would go with APS TT kit. That is the best kit and is the most reliable IMHO. I personally don't like either of the ST kits. You may spend a bit more on the TT kit initially but whatever problems they had have been remedied by now and most people will be familiar with them. I'd stick to the proven ones even if it means spending another 3k....

 

for $8.5 grand, installed, you could get the new VRT / J.W.T. Twins turbo... installd with the "works" & professionally tuned... that's what I was just quoted $8,500 not bad for a complete set-up. Worth a look

by the way I have an ATI procharger(7 months now) still very happy

 

Hmmm the price I got was a LOT higher then that.

 

The one I got was starting at 9k.....I guess they have a lot fluctuation in prices

 

I have the greddy TT

Now if you just want something more riliable then yes go with the APS ST

Now if you are thinking in the future of making more power then i suggest greddy just becouse the fact that is TT and it has the 2nd biggest turbo's for the Z's (i think correct me if im wrong)

 

Steve, some clients are further away than others and we try to offset the expense for them do to shipping , you understand.
Your quote wasn't much higher than that at all. I was also including on your quote (given your flare for pleasing to the eye things) a fully polished kit with the removal and installation of the old/new motor. Make more sense now?




Scott at VRT,

the greddy kit in "stock trim" is perfect, the reason why alot of greddy's blow, is because the tuner cant tune the emanage right. I had a emanage for a long time, before i switched to a fcon, yeah the powerband could be better, but a greddy kit will own a ST turbo kit (no hatered) look at ST HP numbers barely past 400, even with a built block. I have riddin in a St and its like night and day, the ST only has hi torque at redline, power also was mostly made close to redline. A TT kit will throw you back at about 3k rpms. If you just want akit you dont have to mess with go with the APS TT, but if you got a good tuner, get the greddy

 

Greddy will work for ya if you dont do stupid things... Lots of people can find it reliable after a proper tune... and wont think you can make 500whp without internals... Just get the UTEC, greddy, and any other parts to help you judge how well the tune is performing and you will be fine!

 

whats the biggest turbo if greddy is second?
and another question: is the greddy TT a "better" kit if the goal is to pursue BIG horsepower?

 

I am going to make some general thoughts appear in those post and I don't know where it's going to go and I don't have the time (right now) to make one of my monster posts (that some of you love and hate).

(1) I can't say anyting technically myself, against the Turbonetics kit,
as I am not an engineer, and I am far from an expert.

I do not believe there is anything "wrong" with their kit but from what I've
come to understand, from people with more engineering/application
experience there are some "less than desirable issues" in the overall design
of their kit in comparisson to the APS ST KIT.

I will not attempt to make these explanations, because I do not have
the technical knowledge to make them personally and I don't want to
misquote anyone or mis-state the facts.

(2) I am personally not aware of any real issues with any APS TT or ST kit.

This does not mean they do not exist.

I personally have posted about minor issues with my kit, and my
recomendations to those considering APS KITS or any FI KIT.

The concerns primarly revolve around installation and tuning.

(3) I would like to be made aware of any issues with TT or ST kits as I
do speak with a lot of people and provide the best information I can
and don't just tell people "but an aps kit because I think they're the best"

(4) I made sure that I post in general that there is nothing wrong with
going with any SC kit, so long as you uderstan what you are getting
now, and what you can do in the future, and what those costs are going
to be.

I think anyone with long term goals should go with a Turbo Setup VS
a SC setup, just because TURBOS CAN DO MORE, and DO MORE EASILY
in comparison to what an SC can do and what it takes to get an SC to
deliver.

(5) In my opinion turbos are better than super chargers, but this doesn't mean
that SC's are bad. If you want what a SC has to offer, then there is
nothing wrong with it.

People can go round and round about parasitic loss and the heat issue,
and then go on to say that turbos make energy from exhausted/wasted
energy and how turbos are less stresful, etc..etc...etc..

All those points are open to interpetation, and none of those points is
an absolute it is impossible to consider every variable and setup out there.

(6) Someone mentioned they had an APS ST and said they would rather have
gone with a TT, and I wanted to know what the reason for that is so
that I can conisder that when I recommend it to people.

This would also be beneficial to those who are reading this thread.

A general statement being used in regards to why consider an ST is
for about the same money as an good SC install/setup, you can get
a single turbo setup, and in general the opinion is Turbos are better than
SCs so you can get a better setup for the same money going with an ST
VS a SC if you are (a) constrained by budget (b) do not want more than
what an SC or ST has to offer IN THE FUTURE.

PEace!

 

I believe it was me that said this. My main reasoning for this is bc I have come to the conclusion that I do not like the placement of the turbo. The oil feed to the turbo has gravity acting on it due to the low placement and in the case of a faulty checkvalve (such as mine) this becomes abolutely horrendous. The turbo will end up leaking through its seals and all the smoke that was billowing through the exhaust somehow caused my MAF sensor to go bad and all of a sudden I was running dangerously lean. The piping that comes off is seriously low and you have to be extremely careful even when going over the smallest bumps. I was very disappointed in this since there was no mention of it to begin with. No one can deny that regardless of how fast the ST spools the TT will always be ahead even if only by a couple hundred rpm's. On top of all this the TT kits have been out for a while now and several people have them without issues and if there is an issue it will likely be solved quickly. I just think its the smarter decision if your gonna spend so much money to begin with. Hope that answers your questions

Thanks so much for that feedback, I think the issues you raised are valid concerns and I am sorry to here that you had that problem.

What if anything, do you know, what APS has to say about that?

I know that APS gets nothing but a big fat "F" for FAIL on Public Relations, but I sure hope they had something reasonable to respond with and I think I'd like to know about that as well, just like I wanted to know why someone wouldn't want the ST.

Thanks for your time and effort, I can tell you that I sincerely appreciate the info, and I know that people, looking for REAL INFO will also appreciate it as well.
