Ok, I'm going with the APS TT kit....and I need to know what else I will need or what would be recommended to have.

This is what I have:
Helix Test Pipes (I "think" these will work with the turbos)
Nismo S-tune suspension
JWT intake (useless with the turbos)

This is what I'm planning on picking up:
APS TT kit (duh)
JWT or ACT clutch (taking suggestions!)
Wideband O2 (also taking suggestions)
Some boost gauge/ turbo timer combo (again..taking suggestions)
boost controller?
Borla TD or APS dual exhaust

I'm planning on running the 9psi that the APS TT comes with for a while..so I'm not thinking about building the motor yet.

 

The Helix pipes should definitely work with the APS TT kit.

Agreed, sell the JWT popcharger on Ebay or something.

What are your power goals? This might help with what clutch to pick.

What do you need to do with the wideband? Are you going to datalog or just use it to monitor?

I recommend the Autometer Nexus boost guage, neat gadget, plus it reads in PSI as opposed to the Defi BF or Links that read in lbs.

Not sure about a turbo timer, maybe someone can suggest something.

Don't think you need a boost controller. The Unichip piggyback should have full capability of controlling the boost.

My personal opinion, either one of them would be best, go with what sounds better to you. I'm going with Borla.

 

my advice:
acquire and build now with parts that will be compatible with your future (after engine rebuild) goal...for example, i have the ats clutch/flywheel 1100kg...supposed to be able to support 700-800 rwhp/tq...but will work just fine with 300-400rwhp....because parts like the clutch/flywheel can be pricey (2K), get the good stuff now, and you won't HAVE TO replace everything after your rebuild...again, i'm assuming that you'll be doing a rebuild in the future

I know I didn't really specifically answer any of your questions, but it's late, my brain is only working at 25% of its normal. goodnight

 

Agreed, it's really good to get parts that can be used before and after a build when going F/I.

 

As of right now I really don't have plans to rebuild the motor. If I do rebuilt it...the clutch I get now will probably be nearing the end of it's life anyway....my goal is a turbo Z with over 400whp that I can just drive...and not worry about **** with.

 

So what's the story on the boost controller guys??? Can I run 2 different boost levels or will I have to get it retuned everytime I want to change the boost.

 

Ahh ok.

Okay, then nothing crazy internally then.

 

I would really like Peter to chime in on this. I also want to know how many maps can be saved onto the Unichip piggyback.

 

I believe you can save two maps but you can't switch between them without the Unichip software whichs means you will have to visit your unichip dealer when you want to switch. Thats the only downside to it, you can't have a a/b switch and just switch.
Also as far as exhaust, the Borla is VERY restrictive when it comes to forced induction, and back pressure... We have had better luck with the Injen but still will not be as good as the APS....

 

-Tuan @ GRD can help with the boost controller question. But I haven't read anywhere anyone currenlty using one on their APSTT.

-You might as well go with the APS exhaust if you don't have a dual already.

-I would also upgade the radiator and get an oil cooler..not sure if APSTT comes with the oil cooler.

 

The Unichip controls the boost for the APS TT kit.. Also, an oil cooler isn't really needed for the base kit since it comes with a finned larger oil pan... Also, we are running the Koyo radiator and it fits but was a pita to get it in their with the discharge pipes.... Alot of cutting of the shroud had to be done...

 

If you want to run multiple boost maps all you have to do is add an EBC. My favorite is the Blitz SBC-iD. It has 4 different boost settings. I plan on swapping the APS boost controller later this summer.
The APS exhaust being 2.5" diameter will have less back pressure than anything else out there. Most current exhaust on the market were engineered for NA 350Z in mind, therefore more back pressure.

one3502nv,

I would imagine the Koyo radiator or any high performance aftermarket would be hard fit on any TT setup. I guess I'll find out the exact same when mine comes in. Maybe I'll just wait for the built motor...

 

I have been running the stock raditor with my APS kit and about 400whp with 0 coolant or oil temp problems... We added the koyo to our 600 hp built APS motor but have yet to run it in hot weather yet so I guess we'll see.... Yes it did fit but it took MAJOR adjustments to the shroud and mounting points.... Also, it brings the fans about 1/2" closer to the motor which makes it very close to the new lines that are run...

 

i wouldnt recommend the JWT for over 400rwhp... mine held the power for as long as it did... but when I pulled the engine out I noticed it was wearing pretty bad. You saw the abuse live in person so you know how I drove that car... I think you plan on driving the same way?

Did you ever see the HKS wideband in my car? I cant remember if you rode in it or not... very nice piece but a little on the expensive side, and uses expensive NTK sensors... price just doubled on those sensors.

HKS EVC Pro is my favorite boost controller... its smokes the SBC i-D in appearance... but the problem with it is that it does not support boost by speed or gear... so if you need that type of feature, then your back to the SBC i-D and Power Meter combo.

All nice EBCs have built in boost gauges. Another advantage of the HKS EVC Pro is that you do not have to run a vacuum line into the car like with other EBCs... the map sensor for it is built into the solenoid unit.

Aftermarket radiators fit fine with the Greddy kit, havent used one with an APS.

Will be nice to see another Z in chicago representing! This year your gonna have no trouble keeping up when we make videos!

 

Yeap the HKS EVC Pro is another really nice unit. Either one will be fine IMO.

 

With the V-Pro you sell, is an EBC included? Reason being I wanted to save multiple maps.

 

ok....so the JWT clutch is probably out...what will give me better holding capacity than the JWT and still be pretty streetable?? ACT???

So I guess what I'm taking from this thread is that if I want to control boost all I have to do is get an EBC...but if I want to change maps (I'd think this would be necessary with different boost levels) then I'm going to need to have the unichip software???

 

you should not need to change maps for different boost levels... just for different fuel octanes. This is because the APS kit is tuned by MAP sensor rather then MAF... tuning a greddy kit is different because your tuning for the same maxed out MAF voltage after 5 psi, so the E-Manage has no way of sensing a change in peak boost... unless you add the MAP sensor yourself.

But since APS is MAP tuned, you shouldnt really need to change maps at all unless you have going to runner boost higher then you would run on pump gas and you want a different high octane tune.

 

ok cool...so I could get an EBC and run a daily 6-7psi and then turn it up to 9 when I "need" to on the same tune?

And yes..this summer is going to be a blast...I'll still have the slower Z..so I'll be the cameraman...
