Forced induction insight and advice needed

I modified my Nissan Titan with SUPPOSEDLY good parts. I have had nothing but problems, and regret the thousands I spent on it. After the problems appeared, more thorough research turned up that for a few people, they also encountered the exact same issues and after spending tremendous effort and money to solve the problems, they all just cut their losses and sold their trucks. I'm going to need to reinstall expensive OEM parts back on to my truck to get her running right again.
This experience is what keeps me from modifying my Q60, I really don't like how torqueless the VQ is, but I am loving the reliability of the Q60.

Did Vex say he was going to modify a 2020? If he did I would strongly advise him to wait for the new 300Z TT. It will have the VR motor in it. If Vex buys a new 370Z and then drops $18K on it...he'll be way over the buy-in for a new VR powered Z.

Heck, I watched a YouTube channel that had a story about 3 great "sports cars" for under $10K. One of them was a 2009 370Z. They paid $10K for it and it was in excellent condition. I tried to find a 370Z in my area (WA State) for near that price, and the lowest I could find was $15K. I had an idea that at $10K plus the $18K for boost would make for a decent turbo Z project, but if I can't get one under $15K then I need to drop at least another $18K that would be up to $33K for a car over a decade old. Some of the older 370Zs may need extra money to repair issues like rear diff bushing, steering column lock, wear and tear, etc.
Or I could wait until the new VR powered Z drops and just buy a factory turbo car for little more. The new VR powered Q60's are getting sorted, there's people running low 10's and high 9's....that's with 7AT and weighing 650 pounds more than a Z.

I custom fabbed my own turbo for my 2013 ford raptor making 680hp and it has 25k boosted on it without a single hiccup. 🤷

I realize many people have good outcomes with their vehicles when they are modded. It is all dependent on:
quality of parts
knowledge of people doing install
knowledge of tuner
access to appropriate tools (doesn't need to be the best/fanciest tools)
access to fabrication in many cases
time
money

I'm pretty sure you have access to the majority of that, and you definitely know what you are doing.

When I did the LT headers, full exhaust and UpRev tune on my Titan, almost all of the feedback I saw on that was positive. Unfortunately, when I ran in to issues, I found out those were well documented also, however I didn't come across those topics until I searched the specific issues I am having. Such as when I received my parts, I could tell they were poorly fabricated (everyone said "it'll be fine, they all kinda look like that") then the engine codes that indicate exhaust leaks. The incredible hassle of working on a Nissan Titan compared to any of the Big 3 trucks (nearly impossible to do headers on the 4x4 without losing your sanity) and lastly the incredible noise that took 2 UQ resonators to tame (still too loud). Then the tuning...eh, how can the tuner not realize that the left bank of my engine has a persistent exhaust leak (from the crappy headers I bought)?? They kept tuning despite obvious AF imbalances. This has been a bad experience for me. When calculating the cost of having a turbo 370Z, it gets so close to the cost of a new, already FI car (next Z) for the average Joe, that it may be worth considering getting the car that is already boosted AND brand new.

My previous car, a 2016 GTI, all I needed to do was slap on a JB4. Which happens to be available for the VR. I am sold on that approach now.

Also, right now, the market is in turmoil. Parts are hard to get in some cases, I personally have had problems with metal fabricators in my area due to them being fearful of the 'rona, and used car prices are ridiculous.

If I truly could get a first or second year 370Z for under $10K I would DEFINITELY have another go at modifying. For those who already have their Z, that's totally different than considering obtaining a new 370Z then adding boost, when a turbo Z is on the horizon.
