APS single: has anyone had trouble with this kit?
part of the problem was an exhaust leak before the turbo, where the LHS of the Y meets with the xover pipe, there is one nut that was a ***** to get tight. neither myself nor my exhaust guy could hear a leak under normal engine idle rpms, but i guess once the exhaust flow was so high under higher rpms, and once the gases started backing up in the turbo, it caused exhaust to leak there. i started noticing a black mark on the underbody right there that made me suspicious. i still have the manual boost controller on it and the actuator arm all the way tight, the boost still spikes up to about 10 and dies down a little, nowhere near where it was. now im gonna loosen up the actuator arm and close the boost controller some, i think its doing the spike/boost drop now because the swingvalve is too tight. maybe with the arm adjusted correctly and the boost controller right it will go to 9 and hold close to 9 till redline.
can you believe all the BS i went thru to find out its only a damn nut!

Remember richer is safer than lean = boom. Good luck with the kit you choose. Install is the key to any fi kit you get what you pay for.

I can't stress how important that is albeit mine was the first one done by GRD in Chicago.....but they are very familiar with APS in general and have direct access to APS whenever they want pretty much. Thats the reason I drove 1k miles to have them install and tune it. Best move I ever made.
The APS TT kits do seem to have the smoking issues but its also mainly from those that have done the install themselves. Once again if this is the route you go, get it done at an authorized shop that has done it before. We don't exactly know the cause of the smoking yet....and whether its due to a bad install or not..(somehow I'm doubting that this is the case)
Anyways good luck with whatever kit you choose and if you have any other questions I'd be more than happy to answer them...

thanks again... is there anything that u would recommend with the kit? and additions? thanks nexstage350 

Don't forget about a clutch as well...although I'm still on my stock clutch and its holding up perfectly fine after 7k hard miles. Hope that helps..
If you're interested I have an APS single turbo kit for sale along with plenum, bar, gauges, etc.

you can pm me for my dyno sheets; ran it before install, before tune and after tune

As far as the install goes, it takes a lot of time
This is by far the most involved mechanical project I've ever undertaken. I've got ~40 hours into it already, and probably have another 15-20.
I'm really just taking my time to make sure everything is done right.The kits parts seem to be very well made, and fitment seems excellent. Of course, the proof is in the pudding however - my motor hasn't turned over since I started the install

I think if the install is done properly, the kit should be near bulletproof on a stock motor for most people. Since I do a lot of road course track time, I'll probably be a good guinea pig. I'm not deluding myself though. I'm sure within a year I'll either be building a motor as time/money allows, or rushing to get the parts lined up to replace a holed block. My perspective is that none of the FI options will hold up to sustained, regular track abuse without a built motor. My opinion...

Received many pms re my 5AT 04 G35 APS ST install. Here is my update:
I finally puts some miles on - just 25. Too busy at work to take her out for more
In terms of numbers, before the install I was doing 245 hp (mods include injen CAI, Kinetex plenum v 4, borla exhaust and headers)
After install with 8 psi, its running at 328 hp (stock headers are back in and only the back end of the borla exhaust remains) I would scann in the dyno sheets, but I am bit too lazy at this point. Maybe on the weekend. Not big numbers; but I did not install the thing to race, but rather to get over the sluggishness created by the weight of the G35.
It is purring like a kitten, it literally humms at idely, and I love the BOV. There is awesome low end torque and the car is has subtleness to it in terms of speed. e.g., was ripping at 110 in a blink of an eye.
Sorry can't be more descriptive, but I am no mechanic and provide this commentary for those who pm me about my car.

I reason you are just getting used to the Boost, and are very conservative in adjusting to the new system. Yes smooth, and will go to speed ( 130 -140 is speed in an N/A 350Z VQ ) - With your conservative approch - please comment on ability to pass - as required. Ecetera..
Cheers Amy

I have 140 before my ST; but the G was straining; I don't think I will have that problem now.
Passing is no problem; will not bring down the hammer until I break the thing in a bit more.
