Hey im going to get a TT kit soon but someone told me that the APS TT doesnt go ober 12 pounds is this true.

 

Not sure, but I think it was said that the acutators don't allow you to go over 12 psi. If you upgrade the acutators you can then go over 12 psi.

 

who makes upgraded actuators

 

APS possibly? I don't know really, but I'm sure some of the APS guys will chime in here soon. Just give them a little time to get off work.

 

you should get the new "tuner kit" version if you want more boost. call tuan at grdperformance.com, he can tell you. oh yeah - make sure there's an APS dealer near you before you get the kit.

 

Whats the difference between the tuner kit and the kit thats out right now

 

The tuner kit comes without the unichip or fuel delivery mods.

Actuators are available to go over 12 psi.

 

Dude, I'm sorry but your really need to start searching a little bit. Read up on everything you can, and if you STILL have questions, ask away.

Tuner Kit:

Nissan 350Z - Intercooled Twin Turbo Tuner System Since the first release of 'the Z' in the early 70's, Nissan ignited the passion of performance enthusiasts who desired high performance, sharp handling and killer looks. The 350Z has now taken the Z legend to new heights and has produced what is arguably the greatest Z yet. Now, the perfect partnership has been formed in order to take the 350Z to a performance level that will have thoroughbred supercars running scared. Drawing on over 20 years of turbocharging, supercharging and intercooling design and production knowledge, APS has created the ultimate High Output Tuner System for the Z's 3.5L engine. With insane horsepower and monster torque, the APS High Output System moves the 350Z performance enthusiast exclusively into the supercar owner's club. Following on from the huge success of the APS Intercooled Twin Turbo system, APS has acknowledged the desire of some consumers to build extreme power engines and individualize their own Zs with custom fuel system and engine management solutions. To that end, APS has released the APS Intercooled Twin Turbo Tuner System - containing the turbocharger, intercooler and ducting hardware to deliver huge power - but without any fuel or engine management systems. In addition, the APS Intercooled Twin Turbo Tuner System is specified with high poundage 12 psi wastegate actuators ready for high boost pressures to deliver extreme power potential from built VQ35 engines. Along with the huge intercooling capacity delivered from the APS dual entry vertical flow intercooler, the APS Intercooled Twin Turbo Tuner System is the perfect solution for those who demand extreme power potential and desire the freedom to utilize their favorite fuel and engine management systems

 

^^^ exactly. Hey, are you allowed to quote APS on this board?

 

Why not? Were not in Cuba or China. They were banned because they didn't want to pay sponser fee and they were marketing their product left and right. You and I can market other peoples/companies products all day long and it's different. I don't stand to benifit from APS or any shops selling product.

 

I'm working on a quick fix for the low boost actuactor built into the APS system. I'll be able to test it on my car shortly. APS match the fueling kit and the actuators to go hand and hand. Fueling kit is good for 12psi, max boost is 12psi.

 

APS is like crack dealers. They give you a lil taste of the boost. Once your hooked then you want more. Same with the boost.

I hope these babies can run more than 15psi.

 

LOL....I soooo know what you mean

 

so to run higher boost then i have to up grade fuel system

 

Yes.

 

I thought the actuators were limited to 10 PSI, but you could probably achieve a higher pressure through a more free flowing exhaust.

The Tuner version has 12 PSI actuators.

 

Max limit with a free flowing exhaust so far is 12psi on a stock motor. The odd thing that I have found is that on Audi's that have 6psi actuators I've been able to hold boost at 22psi.

 

I have a free flowing dual exhaust and I only hit 10psi.

Oh wait, my new actuators are being installed right now... got them from torquefreaks.com
