Zivman... is your HP setup that way because, that's how you want it?

Your torque is awesome, you've built your motor up, and dropped your compression, so that's always nice, and hence you get that torque, basically 150 over mine.

However I can run 450RWHP right now with stock internals.... I just don't for obvious reasons.

Having that much torque obiously gets you going, so maybe 450 is more than enough after getting such a good kick to start with.

Just in case, I'm not complaining, or putting your setup down, I'm just asking for my own knowledge.... because I'm basically flirting with changing out my connecting rods and plenum ONLY, throwing on 2-4 more lbs boost and I'll go to 450HP and something like 400 trq is the educated guess.

The only question is if the exhaust will allow for it, I'm running the Stillen 2.5" (not really 2.5" in some places).

Why did you get upgraded actuators? What boost are you running? What exhaust are you running?

 

I upgraded actuators to ensure I would max out the fuel setup I had. The turbos/motor was out, and the actuators are pretty cheap so I went for it. My max boost is now at 14 psi, limited by my fuel issue.

With the lower compression I need more fuel up top. More than the aps injectors could supply. I have peak boost at around 4200 rpms @ 14 psi, but taper off to 11 psi at redline due to the lack of fuel as the RPMs rise. True, most stock internal guys can get to the HP level I am at, but you won't have the torque I have without running near 550 whp.

This spring I may retune with the utec or new APS ems and fuel system to get the HP I left on the table, but after driving the car as is, I am happy with the power it has.

 

That's what I figured.

And I'm with you on the rest of your post....

thanks

 

I'm going to hi-jack the thread for a second:

So, it seems that everyone agrees that they are satisfied with the APS TT from a quality and "completeness" perspective. If I did it right with a new kit, new clutch, tune from a solid installer and some dyno-time, etc what should I expect to pay?

APS TT: $7000?
Clutch/Flywheel: $1200?
Install: $1500?
Upgrade exhaust: $1000-sh

About $10-$11K? What did you guys end up spending? Money's not really an object but I want to do it right, keeping in mind I don't want frivolous mods. Thanks...

 

Thanks Alpine,

I was all set to get the S/C until I heard about how bad the altitude affected them. I would be happy with an SC giving me 320 at the wheels, but with the altitude affect, I would be spending almost 8 grand to get 265 at the wheels(A stock Z gets about 200 rwhp at Denver). So a 30% boost isn't bad, but why spend 8K for 65 more HP when for another couple thousand I could easily get 150 more at the wheels.

I have read somewhere that the APS TT starts boosting noticeably as low as 1500 - 1800 rpm's, can you feel it that low or not.

How much did you spend to get yours tuned. Do you have a Dyno sheet posted in the forum? I would like to see how low in the RPM range you see a boost in the torque on an APS TT system on stock internals.

After all the research I've done the APS TT is definitely my dream system, but I know tuning is so critical, and it doesn't look like there are any authorized shops within 1000 miles! I would go Turbonetics as it would definitely get me the power I need for less cost, but the turbo lag is too much. Some of the dynosheets I've seen on those look like it actually lowers the torque from stock below 2500 RPM.

Zivman, thanks for the post, that is an impressive sheet, are those numbers really at the flywheel or at the tires? Either way that has to be a blast to drive!

 

Your numbers are close, and I haven't shopped lately, but I think you need to add a couple 1000 for comfort, mainly in the install area and exhaust, I don't think anyone is installing any TT for $1500 but I could be wrong.

Did the kit come down from $7500?

Depending how far you want to go with exhaust, have you looked at the APS true dual 2.5" and they have a 3.5" coming soon, maybe available now...

Then if you go with gauges, you are looking at another 500-1000 easy, so "right" would include gauges (which I don't have myself)

Tuning is always the trick... you're gonna have about $300-500.00 in tuning easy if they are worth their salt.

 

Sorry... I guess I'm just used to talking about "real affect"... Yes it starts boosting in that range, and right off line without getting on it, I've got about 60trq extra so yes there's boost sub 2000, but you know they are there between 2500-3000.....

 

what is your general opinion on the kit?Best and safest kit with most power out the box...
Have you had any bad experience with it?None
Do you feel that the kit is good for a daily driver?It is my daily driver...like stock when your not in boost..
Do you like the results?Love it my car is a monster......
what would you recommend to be changed?You need gagues, upgraded ratioator and clutch for sure...
what would you recommend to be added?Cams, test pipes, and exhaust for and extra 50 to 70hp
Would you recommend it to others?Definatly..

We'll see how long my car holds up guys....

 

These numbers are more accurate
APS TT: $7500
Clutch/Flywheel: $1200 is about middle of the line; it will get you a spec stage 2+ setup. JWT is cheaper, ATS is more expensive
Install: $2500-$3000
Upgrade exhaust: $1290 for the 2.5" + $200 for test pipes
Gauges: Vary alot but I would at least run a wideband - $400
Tune: maybe included in install, but if it's not, figure 200-400 bucks
For another 400 bucks, a koyo radiator wouldn't hurt

 

Thanks Alpine and Zivman. I don't know of any good tuners in Oregon. (Orygun). What does a nationally recognized tuner charge for a TT install? Zivman mentioned $2500 to $3000. Is that the physical install and tuning + dyno? I'm sorry, but I'm new to this arena.

 

I would stronly recommend my tuners, ED specifically (master mechanic), at Brainstorm Performance, Los angeles, 310-313-0088.

They have cars there from ALL OVER THE COUNTRY regularly...

I have a very good relationship with them, the owners (past and present) and can assure you it would be worth every effort to give it to them, and oregon isn't that far away.

Ask for Christian You can tell them Joe, with the Blue 350z sent you and they will take care of you from there.

I haven't checked on the install price lately, but I it's going to be near 3K and more with complete tuning, but I might be able to help you out with that.

Be sure to tell them what you want the car to do on a regular basis, and what the extremes might be.

If you are a casual driver, with an occasional urge, you can get more aggressive tuning, so you get a bigger kick when you do get on it.

if you are already an aggresive driver, you will want to go more conservative for more safety, although their own G35 with the twins is running with at least 10lbs maybe and doing very well and as this is a demo car, I'm sure it's getting pounded.

This motor didn't even get any break in time, stragiht from dealer, to shop, and twin turbos.

I am probably 80% of what is available, and safe for stock internals.

I could really go to about 90% without too much worry, but since I track, drag, pound it daily, and don' slow down when it's HOT outside, we went with that for me.

Again tuning is more than timing, and looking for tolerable A/F ratios.

 

I hate mine, it sucks! Wish I'd gone with the Stillen SC!!!!

































just kidding!

 

I quality and certified install is going to run $2600-$3000. It is a VERY involved install, by oneone's standards. If a shop hasnt doing TT kits on a 350Z, it would find a shop that has.

 

Sharif, were you by any chance, multi-tasking while writing the above post?

 

sounds like he thinking wasn't
or maybe sleep-posting???

 

That's a given at anytime with Shariff, and myself as well.

That's the only time I look/sound/type that bad... or maybe now when I am overdosing on OTC drugs and syrups to deal with my lovely cold and cough.

 

Dirt, you have a quaife LSD on what car?

I didn't want to assume it was a Z/G, but I'd like to believe that
is what it is.

I didn't know they released it.... I was supposed to be contacted.

If you do have a Z and that LSD, how's it going? What area
are you from/in?

If your in SOcal, any chance of meeting up to check it out?

 

Holy crap that was horrible...even by my multi-tasking-ast typing standards...LOL.

I just had LASIX eye surgery, so my vision is a bit blurry up close. My appologies.

 

WAY off topic, but how are you liking the results Lasik so far? Any itchyness, dryness, or halos at night? I'm debating having the procedure done cause I'm such a wimp.

 

At least he came up with an original excuse!

best of luck with that Shariff, I know many who have undergone that surgery with varying results.
