Default Vortech vs APS ST vs Turbonetics

I have been all over the search button on different forums, reading on all three different kits. But I would like to get feed back from everyone and see what are you thoughts.

I would love to go TT but unless I'm able to wait another year to save $$$ that would be another option.

From what I notice SC/ST run about 3-4k less than a TT. Why Vortech? I live in California and they are CARB legal now, good power, not many blown, good low price, install cheaper than turbo. Why Single Turbo? will never be CARB legal, power possiblity better than SC, Turbonetics comes out next month, I believe for the G35 T-netics is a little cheaper than APS, APS TT has shown to be strong but some have had problems with the smoking, Install cost is about 800 more than SC, ST cost is about 1k to 1.5k more than SC, ST does have that great sound plssshhhhhh..........

I have seen some people sell there Vortechs because they wanted more power and then you have those that have spent more than they wanted going with the Turbo.

Please feel free to chime in and give me your thoughts along with what you have experienced and read. THANKS!!!!

Dude, if you were expecting a reply from someone who knows what the hell they are talking about...ignore my post.

I'm going FI next spring and I'm researching as much as possible. One thing I'm 80% on is that you may save 1K to 1.5K by going SC. I, in turn, planned on spending that 1.5K on Crawford headers. But, from what I hear, stock headers are the way to go with the T-netics ST.

So......with all that said, I basically just hijacked your post to figure out if I'm on track. Someone that is more "Z-smart", please respond and give me the "Aminos, dominos pizza" on this so I can quit skressin' (<-spelled like that on purpose).

Sorry and/or thanks man.

For what its worth I have the APS ST and was told by Peter from APS that the stock manifolds are recommended because they keep the exhaust gas velocity up better than the aftermarkets do. He said that it makes the turbo operate more efficiently.

You are doing the right thing by researching and asking questions before the decision. I've spent the past 3 months reading everyday in this forum without saying anything, and been talking to Peter@APS and Mark@SGP for the past 2 months.

Of course I'm still farrrrrrr from being an expert like some of the people here, but just from what I've read and seen, Superchargers are a little more reliable than turbos because turbos esp. TT's give so much low end torque that our weak stock rods might not be able to handle. But turbos do have a higher tuning and power potential than SC's generally speaking.

Sorry if I didn't answer your question, as I am still growing my knowledge as you are. So don't want to say too much :P But yea I've decided to go TT in the next couple weeks. Parts all ready in my garage.

Well honestly I have had the Turbonetics kit on my car for over 11k miles and to date it has been about as fun and reliable as I could ask for. I have never had a major issue and the car is night and day more fun to drive then stock. Not to mention Turbonetics customer support is about as good as it gets. Any questions whether from me or someone else are answered immediately and any issues are resolved just the same. The power delivery is nothing short of amazing in my book. Full boost around 3200 RPMs and 371 on a Dynapack at 8 PSI with daily driver reliability is perfect in my book.

if they have problems with the turbos smoking they might not have restrictors on the oil lines (since APS uses ball bearing turbos if I'm not mistaken)

miaplaya, you're a ***** (remember me?)

yes I do... and yes I am...However APS is using restrictors according to all the installers. APS claims its a return line issue...but others have not been as successful...

Haha is it just me or way back when folks were downing the Turbonetics kit since it uses the stock exhaust manifolds and then APS came out to doing the same thing


Anyway many folks here have the Turbonetics kit (when considering the SINGLE turbo). Including myself, it is a great kit. I have seen the Vortech's, the Stillen's, and the Greddy TT's in person... And this kit is much nicer looking.

There are alot of threads on the subject, better when searching to just do one at a time...

EXAMPLE: Search = Turbonetics, Search = APS, Search = Etc.

The turbonetics is the best kit out of all the ones you listed.... puts the most power straight out of the box and like Miaplaya said there customer support is nothing short of perfect!!!! If you want the most bang for your buck I would advise going with the Turbonetics kit.... and get a Fuel management of some sort and you will be 400rwhp+ no problem!!! Look at the videos in the video section shows the turbonetics Z killing all of the cars!

I have an 04 roadster. I thought the car was slow so I purchased a Vortec super charger. I have cat back exaust. I dyno'd at 376hp and 309 lbs torque at the wheels. The car is wicked fast and reliable. I personally like the feel of a turbo better but this car is fast enough. Plus I wanted to be able to afford tires, wheels suspention mods and other enhancement. If you go with a turbo you can get great boost but you should rebuild your bottom end.

MIA posted this on a different forum and there is a comparison of both kits:

Turbonetics tuner kit: $3800
Emanage Ultimate: $595 with harness: http://www.cprace.com/Merchant2/merc...s/GRE-15901500

RC 440cc injectors: $530 http://www.forgedinternals.com/store/home.php?cat=251

CJM FULL fuel return system: $970

Total cost $5895

APS Single Turbo kit: $5890 http://www.turboperformance.net/bsp/


So lets compare now...APS has a new oil pan which I will say is a nice feature compared to none with the Turbonetics kit. Does it make that big of a difference...well thats up in the air. I haven't seen any actual logged temp difference between the two and I'm not sure if you can fully use the extra quart of oil that it has the capacity for due to smoking issues. Or was that just with the TT kit? Correct me if I'm wrong. That is the biggest pro for the APS so far IMHO.

Fuel system: CJM or AAM fuel system are HANDS DOWN better then the APS style system. I think we can all agree on that.

Turbo included: At this point theres no telling HOWEVER the external wastegate included in the Turbonetics kit has not had HALF as many issues as people have had with the APS internal wastegate actuators

Engine Managment: The Emanage Utilamte has had unbelievable success so far and while the Unichip may be on par (in some peoples eyes) it is diffcult to find and "authorized" tuner for that compared to the Emanage which can be tuned more easily and by more shops

Intercooler: I think its a draw here. Both are bar and plate intercoolers and unless someone has actualy flow numbers here I think we can agree that they are both fine. The Turbonetics Spearco unit has less then 1 PSI drop across it and I think the APS is the same.

Performance: Out of box, no tuning the Turbonetics kit puts down 377 RWHP at 8 PSI. Out of box no tuning the APS kit has put down around what 330-340 RWHP at 9 PSI?

tuned with mods mentioned above at 9.5 PSI with the APS exhaust which is a what $895 option? the APS car according to APS is making what 386-400 RWHP? The Turbonetics car makes 401/418 at 9 PSI. Now lets keep this non-personal and just compare..for the dollars spent its hard to beat the Turbonetics tuner kit with the mods listed.

Edit:

Just to make this EXACTLY apples to apples:

APS 2.5" ST exhaust =$995 + $5890 for APS ST kit= $6885 power when tuned according to APS 386.4 RWHP with 94 RON gas


Turbonetics kit as equipped above= $5895 + Apexi N1 3" exhaust($599 http://www.hopupracing.com/cosoapni35ex.html)= $6494.

Thats a price difference of $391 with which you could if you chose purchase and install the APS upgraded oil pan. If so making the prices equal you get:

APS as equipped= 386.4 RWHP at 9 PSI on 94 ron
APS tuned plus Nismo exhaust ($950) at 9 PSI and 93 octane= 380 RWHP
Turbonetics as equipped= 401 RWHP and 418 ft/lb at 9 PSI on 93 octane

End result similar power with the Turbonetics being slightly higher but easier install, easier access to tuning, better fuel system with more head room.

Glad you guys like...speaking of which...I am working on putting up my own server for something I am calling the "Turbonetics Owners Club" A nice little place to put up pics/vids extra...no charge of course...ALso me and kcobean are talking about having a Turbonetics Z/G rally next year for SEMA. I've been talking to some possible sponsors for us to get all of our cars on the walkway outside the show...I can't say its going to happen for sure but at the least we are trying to plan a caravan (massive style) of all Turbonetics owners to the SEMA show next year...Passes are being worked out now...

Miaplaya:

Good stuff, I like how you laid out the info and comparision. I have not checked every item you listed but I am sure if it is debatable at all, the boys from APS will let it be known.

The kudos I listed regarding the Turbonetics kit in the turbo article in last summers issue of Sport Z magazine ring true being:

* Easy to install and service.
* Priced significantly lower than the competition (TT is what they were compared to).
* A one year, no hassle warranty on all components.

Bottom line: The user friendly, affordable turbo system has arrived.
