I can’t wait for AMS’s Turbo Kit anymore. After kicking tires for a while and a sh!t load of research... I finally did it! I have placed multiple orders on a bunch of parts to hopefully end my quest for more power and to complete my build. My build will be on stock engine internals and stock tranny (depending on how my car performs on the street and at the drag strip, i might get Z1’s LSD in the future). I’m shooting for a safe (haha) 500 whp / 500 wtq give or take on 91 octane.

——————

PARTS ON ORDER:

•Pure Upgraded Turbos Stage 2
- Ordered directly from Pure Turbos’ website. They retain the OEM turbos’ housing but bore it out and have larger turbine + compressor wheels with upgraded seals. They’re built to order with their quoted lead time of 7 to 10 business days. Edit: Pure’s lead time turned out to actually be 20 business days.

Ordered from Concept Z Performance (CZP):
•CZP by PPE 2.5” Upper Downpipes
- Currently on back order, should receive them in about 3 weeks. Edit: I cancelled this order because there was no guarantee that I'd receive this on time.
•AMS Low Pressure Fuel Pump (LPFP) - Should receive this in 2 days.
AMS RA338 High Pressure Fuel Pump (HPFP) - Should receive this in 5 days.
•AMS Auxiliary Intercooler Tank - Should receive this in a little over a week. Edit: I cancelled this order because it was "drop shipped" from AMS and it's been almost 2 weeks.

6/22/2020 EDITS:

Ordered from Z1 Motorsports
•Z1 2.5" Upper Downpipes
- They currently have this in stock, so I should receive them in a few days.
•Z1 Urethane Motor Mounts - They currently have this in stock, so I should receive them in a few days.

Ordered from an Infiniti Dealership's Ebay Store:
Infiniti (AMS) Auxiliary Intercooler Tank
- Should receive this in a few days.


——————

CURRENT ENGINE MODS:

•Specialty-Z EcuTek E-Tune
- At 19 psi on Shell 91 Octane and have ran this for the past few months.
•Add-W1 Oil Catch Can V3.3 - Got it directly from Add-W1 and have had it on my car for the past few months.
•Fast Intentions Resonated Touring 2.5” Catback Exhaust - Got it directly from FI and have had it on my car since 2017.

Bought from CZP and has been on my car for the past few months:
•Infiniti (AMS) Intakes
•HKS Resonated 2.5” Lower Downpipes
•AMS Heat Exchanger
•CZP Turbosmart Vee Port Pro Blowoff Valves


——————

As you can tell, CZP is my number 1 vendor since they don’t charge tax.

I’m going to install the AMS Auxiliary Intercooler Tank myself as soon as it arrives next week.

Specialty Z is going to install the Pure Turbos, Z1 Upper Downpipes, and AMS HPFP + LPFP, Z1 Motor Mounts, and then dyno tune my car.

EcuTek Tune with the following maps:
•Max psi on VP Racing Q16 - Good for 550 to 575 whp ish, track only
•Max psi on 100 Octane
•20 psi (or max safe psi) on 91 octane
- Good for 500 whp / 500 wtq ish, will be daily driven
•Hot Weather
•Pops & Bangs


If all goes well and if I receive all of my parts on time, I can hopefully get my car into Specialty Z’s shop in about 5 weeks (mid July).

If AMS/Nostrum releases their injectors by then (highly doubt it), I may just add them into the mix too.

I’ll be buying out my lease. My car is currently at 77k miles, so it doesn’t have the factory powertrain warranty any more - this is sorta why I’ve decided to full send it 🏎 🚀

8/1/2020 EDITS:

With this new found power, my car has started to go sideways a few times at WOT, even in 3rd gear at 60 mph. And, I’ve been spinning and not winning off of the line at the drag strip lol.

So, I’ve placed an order on Z1’s LSD. Since I’ll be installing the LSD myself and will be working in that area, I also placed an order on CZP’s RWD Aluminum Driveshaft and Z1’s RWD Urethane Transmission Mount made for 370Z’s / G37’s. Currently there aren’t any official tranny mounts made for RWD Q50’s / Q60’s. Although the Z1 Tranny Mount isn’t specifically made for the Q50, there have been a few people that have used 370Z / G37 tranny mounts on their Q50’s / Q60’s. I’ll test this out on my car.

I was struggling with which HPFP to get. But after discussing my goal of 500 whp on pump gas with Seb from SZ, he stated that the RA338 should be enough. Plus, the big bore is about $1,000 more.

From what SOHO Motorsports have told me, only a LPFP (no need for HPFP) needs to be upgraded and you're able to make 540 whp on 93 with the Pure Stage 2 turbo. Since you're on 91, it will be less.

Nope. I’m hoping to stay in the 500 wtq range which, based on my research of what others are running on the FB groups, the stock tranny should be able to handle.

Got it. Well, I figured since I’m upgrading the turbos and am getting the work done at SZ, I might as well have them add the HPFP just in case. Wouldn’t hurt (except my wallet lol).

Handle it? Yes. A Level 10 upgrade can also correct the hard shifts, gear slams, erratic shift points that this Jatco tranny can produce. Spendy for sure. Ask JohnInNH about his Level 10 upgrade.

Looks like another Pure stage 2 upgrade. Faroog is ordering all my parts today

RS-R DDS compatible coilovers
Front LSD
HPFP 338
LPFP
One piece drive shaft from Concept Z
Pure stage 2 turbos
Re-tune
New spark plugs
Install new gates belt.

New 4S's after I get it back with Hunter alignment.

Ceramic polish and detail.

Should be a totally different car. Thanks to IridiumRS400 for the coilover info.

No clue where we should post our build updates. So far I'm 4 weeks behind my schedule, as I hoped to have it by wk 2 July. Looks like it won't start till week 3 July.

Just fine. Granted it caused Seb a headache with different torque tables. But shifts smooth like stock, but under higher TPS levels and torque demands shifts fast. Thunk! 😁 knowing it helps keep temps lower is reassuring as well.

It's now rated at the higher HP, and more importantly, higher Torque levels. Higher than the Pure stage 2 turbos can produce even with E85 if so equipped. I'm sticking to pump gas however.

All my mods were in anticipation of getting bigger turbos.

As I tell folks here: Research, research, research, and make a plan. Saves $ in the long run, and a better outcome. Not to mention longevity. 🤞

Nostrum Energy killed their original transmission on an aggressive Red Alpha 500 tune around the 500 wtq range if I recall correctly (pretty sure it was before they transitioned to the Red Alpha 600 package, but someone please correct me if I am misremembering). So long as you lay off hard launches from a stop, the transmission is likely fine around 500 wtq.

What to do?
Personally, I "accidentally order parts", but the wife and I maintain separate finances anyway. She knows I buy parts, but she does not need to know precisely how much the front and rear limited-slip differentials cost. :-D

Everyone should have their own thread for their build list.

Would be nice if we could edit a post after 10 days! That way we could keep updating the list on the first page.

Sorry, but I'm gonna gripe about that one for a looooooong time to come.

If you don't want folks to know what you have done, then, of course, don't make a list.

I updated my G35 build list and added pictures only to delete all of it. I don't want details of what is on/in it so it doesn't become a target for theft and doesn't raise eyebrows with the [email protected]

Interesting. Why do you maintain separate finances if you don't mind me asking? Do you each do your own investing?
