Default Internals for 700whp?

I have dreams of forced induction, twin turbo on my Z. My goal is 650+ in the end

So, what are the weakest links in the VQ37VHR? What needs to be upgraded to relatively safely push lots of power?

Rods? Crank?

Any recommendation on parts?

Short answer: You'll have to address head gasket lift. Long answer: Read Spooler's thread.

If you "only" want to push 650whp, i dont know if its worth it to go the mazworx route. No clue what Spooler paid but id be surprised if its anything below 15-20k.

I run 602 whp on E85 with stock block at 13 psi. Its not gonna last forever, but a good 15-25k miles is very much feasible.

Well I'm hoping the car still runs after the car is paid off, and that means upwards of 80k miles, so if reinforcing parts makes it more feasible, then I want to. I know it won't last forever, especially when you are multiplying the original power output, but I'd like to reduce the risk of destroying the engine on a hard pull on a thursday evening.

Eventually I'll have a new daily, and I think the day I have a second car is the day I put the order for the snails

I'm not seeing anything for the 370z on mazworx website, was his stuff custom made?

And from what I understand of this head lift issue, being fairly new to modding in general, is that the boost pressure finds its way past the head gasket and damages it, is that correct?

If I had to guess, this has to do with the fact that there appears to be 8 mounting points on the head and gasket right, so if you boost too high, there are areas where there isn't enough clamping force in between the bolts to seal the pressurized air. Is the head gasket just too thin? maybe on the metal itself, or on the rubber seals?

What kind of clearance issues would you encounter if the head gasket were thicker?

Yes. Custom. There's not enough demand for them to put a kit on their website. Call them and talk to them and they'll get it done.

It's the gap between the studs that is the problem. Thicker gasket ain't gonna do it.

Makes sense. Just this conversation alone I have learned a lot about what this engine, or any engine needs for that matter.

At first I didn't understand what head lift actually meant, but now I get it.

So the top end of this engine is its weak point with its head that only has 8 mounting points to hold the entire head onto the engine. The gaps are too spaced apart which allows it to flex under pressure. To me that actually does make the weak point the block itself since the head was designed to attach to the block.

This aluminum engine head can't stay rigid against the top of the engine with only 8 mount points. A stronger head with its current mounts seems like it could only do so much.

Man I have ideas that could turn the Z into a Koenigsegg. Think freevalve. Question is, do I have the budget to make it happen

I don't know if it is sticky material. Sometimes I wish it would get deleted.

You will need about 50 to 60k to get started. If you want to shotgun it and do everything all at once, 75 to 90k. The down side is it will take about 1 1/2 years at best at a good shop. You can
go to a cheap shop and they can bubble gum weld you up something on the cheap with ching chang charley parts that will Nickle and Dime you to death. Your choice.

If you want to see how bad it can get if you don't listen, read this thread. He sold the car and lost his butt.
