Personally, I got a laugh out of the writeup on Turbonetics website for their 350Z kit, perhaps it needs updating? I thought APS was the king of hype, but Turbonetics is trying hard, see if you can spot the incorrect or disputable items. Check APS's website for a great description too, several paragraphs of saying nothing but hype, even the parts section uses words like huge. Maybe both companies need to take a deep breath and offer facts.

Turbonetics' Nissan 350Z turbo system is the first and only production single turbo system available. Utilizing our proprietary ceramic ball bearing turbocharger, this system outperforms all twin turbocharger kits currently on the market. The unique engineering design of this system retains factory exhaust manifolds, therefore reducing overall installation time significantly. Installation of the kit can be done easily with basic hand tools by a qualified auto mechanic.

 

so the skimmed on a few areas on their kit... APS is no angel either...

but that statment you made.. its kinda out there.. the quality is really not that much of a HUGE difference

 

def

 

Hey ! thanks to all for your great comments and feedback !

it is getting more clear for me now...

for what I'm looking for, I think APS will be a good choice...out of the box...

not because TN is not a good kit, but just because the APS out of the box kit is more reliable... no need to buy supplementary parts... take it out of the box, install it and pay your tickets...

like I said, both are great kit for sure !!! but for what I'm looking for, I think APS will be a good choice... with the APS ST exhaust system...

thanks to all again... I appreciated your patience..

 

personally.. as i stated before.. i would go with the APS TT system.. and if you want an ST system go with TN ... i don't like the APS ST ... the boost drop.. the fact it needs an APS Exhaust to work properly...

 

yah...
i woudl take the JIC single anytime over the aps exahust

 

i have the aps st and the aps exhaust and i must say that i am completely satisfied, of course i cannot bash turbonetics because i have never had any experience with them. all i can say is that i have not experienced any problems, boost drop, noises....anything, i've put about 4k miles on it....however i don't drive hard, i only stomp on it when i feel the opponent is worthy.....lol. anyways, good luck on ur decision and i hope i helped. lata man...

 

IMO, the quality difference is noticable, but that was not what I was getting at. APS addresses all aspects of converting a N/A car to FI. They properly address the EMS, boost control, Fuel system, etc. They did not simply look at bolting on a turbo and getting by with the bare minimums and hoping for the best (done so IMO to hit a certain price point and mass market the heck out of it). If nothing more than looking at the dump pipe on the TN setup, you can see that APS is superior by design alone.

 

I agree I would run the TT setup vs the single, but to say that because you wouldn't want to run a proper FI designed exhaust is just comical to me. You wouldn't want to buy a properly designed exhaust, but see no issue running a joke of reflash, no fuel return, having to tap your oil return, or running a space limited dump pipe due to, what I consider poor, design???

 

You envy me thats all.

 

The exhaust is what it is. It mates up properly, resolves any boost drop issues, and still sounds pretty nice. I don't see any real downside unless you just hate the sound of it. IMO its not terribly expensive either...right around where other exhaust prices are..

Either way a free flowing exhaust is encouraged in any FI kit

What do you guys think of this kit. I'm thinking of bidding but I don't want to purchase anything that will give me problems or have to purchase additional items.

 

there are several kit for sale in the classifieds here also . Just be careful and do some checking before buying a used kit

 

I don't think the exhaust has anything to do with most people's tapering boost issues, but that's just me...

 

That was written 2 years ago when Turbonetics was the only single turbo system and out of box Greddy cars were making 350-360, APS was in the 370-380s as only the first batch had arrived, PE cars were in the 350s-370s. That was all that was out..

 

Oy vey...
Here we go again.

 

Proper EMS? A 15 year old Unichip with DOS based tuning software? The fuel system is adequate at best. The dump pipe? Which pipe is that? The only thing Turbonetics "dumps" is the BOV to the atmosphere. APS design is superior? Turbo at the bottom of the car where even APS owners admit they scrape the housings on speed bumps. Boost drop unless you use their exhaust, faulty check valves, half@ss wastegate system unless you buy at an added cost their external wastegate pipes AND a Tial wastegate. Subpar customer service, an abysmal warranty system, do we need to go on?

 

This has gone beyond ridiculous at this point... I am not a fanboy of anything, in fact I do not even plan to FI my Z but this last statement is a bit out of line...

As opposed to what, a non-tunable reflash?
A rudimentary return system is worse the none at all?
Lowered cars scrape, I did not hear anything about stock riding height having issues, and as you know, I've considered every kit out there.
The chack valve is replaced, Tial 38mm WG is $225 at SGP, any turbo kit benefits from an exhaust and $995 is competitive with others. Both kits will work out of the box, TN can benefit from third party accessories as well, such as a tunable ECU, fuel system (maybe a full fuel return would be an overkill for stock bottom end power levels), definately an oil pan upgrade...
Both kits have their own ups and down. Working out the inadequacies in either one will probably cost around same $$, so it really comes down to which system you're a fanboy of. Which basically is the source of this banter.
That is the only TRUE advantage that you have mentioned so far.

Scroll to the middle of the page.
The only owners who'd scrape their housings are the ones who forgot to install the impact sheild.
BTW, if I still do go FI, it will be a custom Greddy TT based setup done by MRC, so I am not biased to either company. And if the motor blows, it blows, I'll buy a built one.

 

Yeah, but really, shut up, especially if you don't own a Z.

 

Actually I do own a Z. I finally test drove a GTO and was not as overwhelmed as I was by reading the specs in magazine. Too heavy, too much body roll, I didn't like the brakes (I have Brembo GT on my Z), etc.
Anyway, I kept the Z. This spring I am getting a valve body upgrade and a set of Greddy coilovers. After that, who knows...
And as I said, I am very much prepared finacially for a blown motor scenario and will not bother with any of the ST kits.
