No Going Back Now... Z1 Turbos • Z1 LSD • CZP DS • Depo Racing 3” FDPs + AAM 3” CBE • Spool FX-180 + FlexFuel • & MORE!

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 - See 6/22/2020 Edits.
•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 - See 6/22/2020 Edits.

——————

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 and are really responsive when it comes to inquiring and ordering parts.

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 🏎 🚀

6/22/2020 EDITS:

Ordered from Z1 Motorsports

•Z1 2.5" Upper Downpipes

•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.

I’ve decided to run Flex Fuel Ethanol on my car with the AMS Flex Fuel Kit. I’ve also enlisted RaceBox to remote tune my car for Flex Fuel Ethanol.

——————

8/1/2020 EDITS:

With this new found power on Flex Fuel Ethanol, 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.

Since my car is currently at 79.5k miles with the factory motor and factory tranny, I’ve decided to bulletproof my car by building the motor and maybe building the tranny. Additionally, I’ve fallen down the slippery slope of the rabbit hole known as, “MO POWA BABEH!”


I’ve placed orders on the following parts to upgrade my current setup. I’m gonna sell my old parts to recoup some of what I’ve spent.

•3” AAM Resonated FDPs & 3” AAM Resonated CBE. AAM does not keep stock of their FDPs and CBEs for the VR30; they’re made-to-order with a 3-4 week lead time. And, AAM Competition doesn’t list their 3” CBE with resonators. So, since they have to fab their CBEs when customers put in an order anyways, I called them to request that they put in resonators at the mid-pipe section of their CBE; they fulfilled my custom request/order. To get the most out of my PS2 Turbos, opening up the exhaust with a full 3” turbo-back gives MO POWA BABEH!

•DeatschWerks 19S-00-1700-6 Injectors, Spool FX-180 HPFP, OEM Left-Side Fuel Rail 17522-5CA0A, OEM Right-Side Fuel Rail 17521-5CA0A. I’m gonna test out this new, relatively inexpensive (compared to AMS) injector option on full ethanol. More fuel for MO POWA BABEH!

I’m still working out the details of building my motor and maybe building my tranny. If I build the tranny, I’m going to use my builder’s recommended tranny builder (NOT Level 10). This, of course, will enable me to reliably run MO POWA BABEH!

WARNING TO ANYONE THAT’S THINKING ABOUT DOING BUSINESS WITH KRIS KUNETKA / K2 RACEKRAFT - DON’T!!! If you get Kris to work on your VR30, then you may end up with an improperly machined head and a major oil leak that’ll drain your oil at 1 quart for every 150 miles driven.

One needs to be careful posting things like that or you could be sued for libel.
Fair. Yeah was just trying to think of the best way to get the word out so no one else gets swindled by K2 "Race Craft". I bet Boost In Motion would cover it on his channel.
This is probably not the best ice breaker on a new forum....

I will clear up a bit of the confusion / speculations.
• Kris / K2 is his own entity. He is not or was ever an UpRev employee. Kris was simply using some shop space we provided for him to work on cars.
• The agreements which we (UpRev & K2Racekraft) had did not come to fruition so we decided it was best for Kris to move out of our shop and continue doing business on his own.
• On January 15th 2023 he was given his formal 60 day notice to vacate the shop so that we could use our shop space for our own R&D projects, bring customer work back into the shop for UpRev to do under our own supervision, business structure and quality control.

Libel is a tort claim and not subject to the rigors of a criminal claim. I agree with you if written statements made are factual and indisputable. Making disparaging or derogatory statements about someone's reputation or character on FB or public forums can muddy the waters in any civil claim.

It's best to avoid statements like this: "Hopefully! Yeah, he was a “Master Infiniti Tech” at Austin Infiniti before he decided to become a con man."

Just saying...

there is a lot of corruption.

a friend of mine went back home and connected with old friends.

it can cost $100,000 to be a police officer.

I asked why would someone pay that much money to become a police officer and he said because of all the bribes that you're going to get.

K2 RaceKraft / Kris Kunetka did not step up and did not pay the Invoice from Overkill Performance. Overkill hasn’t heard from Kris since 3/27/2023. I haven’t heard from Kris since 3/10/2023. It is now 4/18/2023.

I dropped my car off at Overkill yesterday. In 2 to 3 weeks from now, Overkill should have more info on the appropriate repair for the the oil leak(s) issue. I’ll update this thread then.

Wheel Automotive parking light Tire Car Sky


I had to park my car in front of the business next to Overkill’s office because all of the parking spaces in front of their office were taken up. Their office and dyno shop is in that building behind that red Dodge Ram. Their repair/work shop is in a building a few buildings away from their office.

Dang bro. Sorry to hear that. Hopefully Kris will come to his senses and do the right thing. I would not be able to escape the guilt of doing such a terrible job and mis-managing a project like this, so hopefully he will come around and do what's right.

Congratulations on getting married, and having your first child! But yes, hopefully Overkill can get everything sorted out and you can get on with life, enjoy the car, and have this mess behind you. Hoping for all the best my friend.

Meh. Not trying to put any more money into my car right now.

At this point, I just want my car to be somewhat reliable - especially when it comes to the long block, so I’m hoping Kris did an acceptable job with installing the Manley Piston+Rods along with properly installing all of the rebuild parts - my car did make the 1,770 mile trip from TX back to CA with acceptable cylinder compression test numbers after that trip.

And, I’m hoping to just do basic maintenance external to the long block - like 3k mile OCIs, spark plugs every 3k or 6k miles (will depend on how hard I drive my car and what the spark plugs look like during my oil changes), OCC and fuel filter cleaning every now and then, changing select fluids more often like for my Z1 LSD, maybe having to replace some bolt-on parts that might fail such as the injectors, etc. etc. etc.

I understand that there are a lot of new parts for the VR30 that have came out since I started my build back in the Summer of 2020 (it’s now April 2023).

But, at this time, I’m not trying to be the fastest VR30. If my car turns out to be solid after, say, 10k or 20k miles, then I may go down that rabbit hole again… lol we’ll see.
