yea for 400rwhp if your not planning on doing something crazy down the road... i dont see why not just start with the APS system, it will get you safely and considerably over 400rwhp with no issues... just have the 93 octane map loaded in to the unichip before its sent to you, and put it on a dyno to make sure everything is tuned good before beating on it on the street.

 

Sounds good. Now to decide twin or single.. Dah

 

IN your case the only reason twins should be chosen is if you feel like building your engine one day and want more power. The single will max out around a little over 500 whp......otherwise the single and twins will perform very similarly. If all your looking for is the 400 then I'd recommend you save the dough and go single....good luck

 

Not sure how many TTs have been running over 1yr, but I have a Vortech we tuned 425rwhp initially and have put 18K miles on it over 15 months with no major issues. The motor will hold 400hp if the kit is set up and tuned properly.

If I were shopping today (TT kits were not ready when I went with the Vortech), I'd definitely pick up the APS over the GReddy. The APS seems to be a more complete kit and I know of a **lot** of GReddy FI-cars that have popped motors. I'm sure a lot of that has to do with install and tuning, but given the problem is not the kit itself that means so many blown motors shows there are not very many installers out there knowledgable enough to get the GReddy right at this time.

 

I'd be happy with $25rwhp and 337rwtq.......do you get on the throttle daily or do you take it easy for the most part? I'm always getting it on mine and sometimes worry.

 

I don't daily drive my Z, but do take a lot of road trips. I'd say the mileage is pretty evenly split between highway travel (maybe 50%), local "cruising" (20%), and trashing it (30%). I wouldn't be surprised with the mileage I have if the car isn't putting down more like 380-400 now due to wear and tear and to the fact I have not retuned in over a year. But it's strong and I have no issues so I don't worry too much. Finally going for a re-tune this month now that I have the Kinetix IM on and will be adding the 3.12" pulley.

 

Jergens - In case you were wondering the GB for the APS single has been extended till this Friday..so that gives you some time to think about things. We have 22 confirmed payments....need 3 more for the free plenum. Would be great if you could join us...

 

Peter should work for the tobacco industry. He has u all brain washed. He never answers a question without trying to pitch product. And now somehow he has managed to get u all to talk this guy out of the greddy and to go with an aps kit. Not saying greddy is perfect its not but neither is the aps. Can we please provide people with facts and info and let them make there own informed decision. Anyway see sig for mods and best wishes no matter what path u choose.

 

He's interested in both kits if you go back and read....if people wanted to make their own decisions there would be no need for these forums. Our priority is to help them get the best for their goals and their money....plain and simple...no one is forcing him to do anything. He asked for more info and we gave it to him..in the end its still his decision..no one is making this 5k+ decision for him....

 

Zman I did read I'm not sure u did. His original post starts with hey guys I'm buying a greddy from sharif.. How much more cut and dry could it be?

 

LOL...I just caught this thread today, since we were at HIN Atlanta for the weekend.

First of all, I sell all of the kits...Greddy, Vortech, APS, and Turbonetics.

I never try to talk a customer into one kit or another. What I ALWAYS ask first is what are their intended goals with the car. What is the upward path as they continue modding the car. If someone intends to stay at 375whp to 400whp, then any of the kits will work. Some just behave differential than others, some are easily to install than others..etc..etc.

Each kit...has its strengths and weaknesses. I will say there has been a lot of bashing of the Greddy kit lately, but I honestly think most of the issues revolve around tuning, and improper installation. That is my personal opinion....having following almost every single blow up posted on this board. In the most recent blow-up the user mistaken raised the boost to 8psi without any additional tuning or fueling....and even in this case...people are blaming the Greddy kit. Please..lets be reasonable.

Think of the Greddy kit as the tuner kit. With the Greddy kits I sell, I almost always sell a return fuel system, shielded CAS wire, Walbro 255, and timing harness. IMHO, the kit is unsafe without these items...and very difficult to tune...even at 6psi....due to your fuel pressure vacillating widly.

Keep in mind that more Greddy kits have been installed than any othe F/I production out there..so of course there will be more blown ups.

The APS kit is incredibly complete out of the box, but is limited by lack of anyone having any inventory, difficulty in raising boost beyond 12psi, and lack of tuning options...if you dont have a competent unichip dealer near you.

These are all factors to consider when deciding on which kit is the BEST for YOU.
If anyone wishes to discuss the various options, I would be happy to run through them for you..anytime.

Even if the APS system was able to tune as easy as the greddy, there wouldnt be NEARLY as much blown engines as there are with greddy, i bet there would be close to none. Unlike greddy, APS comes with a safer fuel system (everything), and injectors?

 

Sharif,
Thank you. Finally someone with an impartial post. Thanks for you honesty and candor.

I am not expert but what is good for the goose is good for the gander. How do you explain all the greddy tt kits that are running fine with no fuel return? And FYI the greddy does come with larger injectors.

 

I read too...just bc he started out saying he wanted to buy Greddy doesn't mean he knows every other kit out there. Since Greddy was the first kit out..thats the only turbo people associate with the Z. He is simply asking for a reliable 400 rwhp and I introduced him to the APS and Turbonetics kits. I gave him info about the APS (without pushing it on him by the way) and then he wanted to learn more...leading me to believe he did not know about this kit. I only want whats best for my fellow forum members. Why go to all the trouble of buying separate parts for the Greddy when the APS has everything to begin with?..In my opinion it just seems like a hassle. I never said anything bad about any of the kits..nor was it my intention. It was just information...take it with a grain of salt

 

As mentioned, the APS kit is most complete, but still not perfect. When you add up the cost of the greddy kit, plus a return fuel system, walbro 255, and timing harness, you are still several hundred dollars cheaper than the APS kit. Greddy already comes with larger 440cc injectors rates at the industry standard 43psi, vs. the 500cc injectors that APS uses, but rated at 52psi. Essentially, they come with the same size injectors, if flowed at the same fuel pressure.

If people have this complete setup, and proper tuning, the Greddy kits would not be blowing up. Ask SGP Racing how many Greddy kits they have installed, and how many have blown up. I will bet you the answer is none. A good example of how proper tuning and installation is so critical.

In my opinion, the biggest drawbacks to the APS are as follows:

1) Lack of good tuning options. Must be taken to a Unichip/APS dealer for tuning. Some of the best tuners in the country are not APS/Unichip dealers, and will be unable to tune this car. Before buying the kit, just make sure you have a good tuner nearby, that can tune the Unchip

2) Internal wastegates can only boost 10-12psi without significant upgrades and cost. (keep this mind if you plan on building your motor, and running higher boost levels)

3) Dealers have VERY limited inventory...meaning most have none.

And it may shock you to know, that we make more money on the APS kits, vs. the Greddy kits. So I am telling you this, not becuase I am trying to push a higher margin kit. If so...I would pushing the hell out of the APS kits.

In the end, its about setting your goals, and deciding between several very good options. Each with its pros and cons.

 

It's my opinion that its just a hassle to buy parts separately. I'd feel more comfortable if all the parts necessary for the 5k+ turbo came from the same company and have been tested several times in conjunction to each other. Granted there are guys who enjoy doing their own thing....I have no problems with that, but my idea was to simply pass along my train of thought...I don't know what Jergens plans are...

The Greddy kit is definitely cheaper than the APS TT kit....but not the Turbonetics or the APS ST kits. If cost is an issue and you want twins than I can understand you'd want the Greddy kit. This is the exact reason I was waiting on the ST kits...simply bc my goal is about the same as Jergens... ~400rwhp and there is no point for me to invest in twins....

Anyways...whatever you decide good luck and I'm sure you'll be happy. I'm sure Sharif is a great guy and I wasn't trying to make him look bad. I don't think its even possible... I still plan on getting a clutch and gauges from him in a few weeks here.... . Take care fellas

 

Awe thanks ZMan...just trying to share some experiences. I'd be happy to help with whatever kit a customer decides to go with. Lately, I have been selling quite a few Vortech SC's "tuner kits" as well. So there is a market and need for all of these kits.

 

I some what agree with what your saying, but coming from a sale men prospective anything that come in a all in one package is not always the best. Some time the hassle is worth it but keep in mind, if that is case then why upgrade your car, why put different rim, dirffent break kit, a better stero system, why put intake, exhaust or F/I at all. Nissan engineer have put together a all in one fun package for us already. And yes they test it to death but still does not make the car perfect. My point is that some time it’s better to pick and chose then to settle for something a company have put together for you. I have seen the APS fuel system, I’m not knocking on APS at all but it doesn’t look too impressive to me. Like Phunk would say “it look like a cookie cutter setup.” If I had to go with the APS system, I would change the fuel return system, to CJ or AAM system. Currently right now I got the Greddy kit, but I’m not looking to stay within the 400hp range for no longer then a year so the APS kit will not work for me. And again I’m not say APS kit is bad, it might be the safest kit in the market but the limitation is what I don’t like. I would want a APS TT/ST or Techno ST too if I wanted to stay with in those 400 or so range. But I would change the fuel system for sure if i when with the APS kit.

 

Hey guys. Eek... didn't mean to cause a ruckuss. But no everyone has good points on this. If I were going to build my engine, I would have stuck with the GReddy TTs because they are more versital. And I actually did not know the APS Single turbo was out. I had twin turbo twin turbo in my head this whole time cause .. well that is what was out there. But now that I have seen that I'll never tap the true potential of twins, I don't want to just strap on a kit that I'll never get to juice. I don't have the knowledge or the ability to drive for that matter a 550+ HP car. 400 RWHP gives me goose bumps already and I am pretty sure for the Z, that is what I will be happy with. This is my first really built up car and I'm taking steps with each generation of car. When I start making some bank in three years or so who knows, maybe I will go nuts and build a 800 horsepower GTR Grrhhhhh. But for now I am happy that I found this solution and I'm glad you guys could help. I put my 1k down on the APS single unit and trust me I'll be letting everyone know what I think. And yes Sharif I will be in contact with you to aquire all the goodies to handle 400. Over the last year and a half of me probing the turbo world you and Tim have been great help to me even if you don't notice. You are one of the most straight forward and honest "salesmen" I've ever met, and you've done a ton for this community. We all owe you a lot.

Now, lets cross our fingers for that 25 down payments. A free plenum would be rather sweet.
