I agree but Z owners can't keep their mouths shut!!!

Noop, the block was sleeved. I forgot the name of the sleeves though. He also has a Bryant racing crank. It is a 4.0 liter. They were
not Darton MID sleeves I don't think. It started with an L, I think.... Not sure if they left any protrusion either for better clamping force
and fire ring seal. What headgaskets, I don't know either.

The same machine shop that built my engine did his. They are no joke. Take a while but who cares...

I really hope it works and it just not another failure on a long list of VQ's dating back to 350'z. I have seen so many fail or make well north of 800whp and disappear. One thing they all have in common head gasket/ pushing coolant.

Its probably a LA Sleeves liner, which I was just telling Seb that is going to be my last effort on the cast block. The last thing I can think of trying is to get rid of the aluminum at the top of the liner, which forms the deck surface. Just bore out the stock liners and put in some dry sleeves that go all the way to the top of the deck. If that doesnt fix it, I am done with that block!

This has been done though, I dont recall by who, or when, or if its being pushed very hard or not.

Even with that, I will still want to perform the other things we worked out to increase the rigidity of the block. Because high power VQ have also been split right down the center of the V before, and no cylinder liner is going to address that.

That's it. LA dry sleeves. I would rather just fix it right the first time. We need 3 more people.

Already been done

Yeah I really think the solution is gonna be the "hoops" not just wire "fire rings". The way they are going to press the gasket into the boss almost makes it impossible to push coolant.

Try it and let’s us know. That statement is just paper weight

Theres been a lot of talk about those lately. I think theres a few guys with builds in the works with them. Hopefully it works out in the long term. 1000hp is hilariously easy for a VQ to make, if only they could hold it for a day.

I don't have that problem yet, but I'm in the works of heading that way. I won't push over 650whp for at least another year. I just spent $15k on a setup and would really like to drive it for a year first. But by the time I'm ready, I really do think this will have proved itself.

REally hope you consider a stand-alone

Wish I was building for big power now

Yeap, if you open up a channel and log Coolant pressure we can get lots more data on the problem. No need for all this damn guessing.
You can't do that with Ecuteck or Uprev. I may wait and get my Motec up and running before I do anything.

Why are you saying I need a stand-alone?
