A twin turbo LS is damn tempting.

Oh yeah, that is my wife's car. I am not allowed to touch it via upgrades. She likes it just the way it is. I am fine with that.

I think I am going to optimze the hell out my car to run 22psi of boost or lower. Install a dry sump so I can track the car if I want and not have to worry about oil temps. I am too far in to change directions.

The wife is pissed about me even considering putting a VQ back in my car. She says I would blow it up again. End of story. She is right. So, No more VQ. Wait and see which way I go.

“You are not going to be happy unless you are going Mach 2 with your hair on fire”

Your will never be at peace if you feel like you’ve settled for a lower goal, especially when it’s because a shop not delivering.

If you can truly be ok with 800whp, pls by all mean save the money. But if there remains an itch, you will end up scratching it….

Good luck sir :tiphat: :driving: hell of a car either way

Note: Lol we talk about 800whp like it’s some kind of unloved step child here :roflpuke2:

We just can't make it reliable with the VQ. I could try again but the odds of failing again are against me. Why waste the money only to have the heads lift again. SOHO motor, that's a hell no. Only way I would even consider installing one is if they gave it to me for free and Nick dang sure wouldn't tune it. My current tune is trash.

Going your definition of “VROOM VROOM” does start “VR”….haha.

is 1000hp really worth it. So much trouble. So much money. Always worrying the engine is going to pop it's gasket.

And at the end of the day can the car even best a 500hp GT3 or Viper ACR X on the track...

Just doesn't seem worth it. Doesn't even seem like it would be fun to drive either...

Despite best efforts and big budgets, at that power level, you are always gonna break something and go back to the drawing board. Further complicating the matter is you are forcing air into an engine that wasn't designed with FI in mind, and that wasn't anything special to begin with. Sure it can take some FI, but once you go over a certain power level, unsurprisingly and despite best efforts, things are gonna start to break and the car will be less and less reliable. I'm sorry to say Spooler, but this attempt to make this engine reliable at anything close to your power goals was a long shot, and you went deeper and deeper into the rabbit hole with potential solutions. It would have been great if you actually discovered a "secret" to making this engine reliable and I commend you for that effort, but the money you have sunk into this to get here ($140k as you mentioned earlier in this thread) is an unfortunate casualty of war. Where you go from here is up to you honestly, but for what it's worth, my advice would be to turn it down and just enjoy what you have. Sometimes less is more.

I will go with a different motor that can handle it. End of story. I have no faith in the VQ to live at 800whp and up long term. It's all good. I gave it my best shot. Sometimes you just have to accept that it's not possible. No worries on my part.

Now everybody knows why folks do +900whp and disappear. I will just do a motor swap and keep on trucking. I am not selling my car. I am a Z person, end of story.

The only sucky part is I should have done this last motor. I just wanted to give it one last try. My 2nd motor is way better, just not up to +900whp long term. My wife refuses to let me even try to put a VQ back in and turn it down. I would never hear the end of that if I did.

So...VR38 or Boosted v8? I would think the VR38 would be easier to shoehorn in the Z.

It sure would be way easier.

It pains me to say this but I sold my CJ Motorsports intake. I never even got to see it in person. Since I am not going back with the VQ, it had to be done.
