Mazworx billet block.

If Z1 would take that million dollar COVID loan they got that was forgiven and do something we all need with it that would be good. You know our tax money is paying for that crap. Rich getting richer and the poor are getting poorer.

There's no reason why an open deck block with hg can't last at 700whp. Yeah, maybe using that power all the time, the longevity will be shortened but how many people are using that power all the time.

It makes no sense for me to do 1/2 mile races. At my power level, I'm not going to set any records. I just want a strong running street car without spending 25k on an engine

700+whp

Spooler

I used 718whp on my first motor ever time I got behind the wheel which was every day. 7k miles and it was done. Stay in the 6xxwhp range with your stock block and enjoy it. Following in my foot steps is not fun. I enjoyed
my first build the most. The car was a ton of fun. If I could go back there, I would.

I agree. But saying 800whp is reliable on any form of open deck isn’t true. Most people who say that never run at that power level. More of a status thing, saying I made that power. 700whp is about the limit of what a oem block can handle. Soho proved that after a year of racing before it shot a rod out the block.

I know its been awhile since the last post, but if there's hope in getting a billet block I would be interested. Nissan is pretty much done with the engine. So If we can convince someone to make a billet block that won't crack past 1000+hp

Spooler

They won't crack. The blocks dance around when the cylinder pressure hits a certain point. The casting is not very good. There was not enough interest. The blocks just by themselves would cost 10k. Very few folks in the community have that kind of money to add that additional to an engine build. It would be whole lot cheaper than a VR38 swap.

Thing is, while a VR38 swap might at first appear to cost less than a billet HR/VHR block build (assuming the block became available for purchase and at a price that compares to other billet blocks)... the cost of being the guinea pig is at high risk of turning out far greater in the long run.

If I ever wind up doing a build on my Z, the only reason I wouldn't just skip to a VR38 is because it serves no use to the business. I couldn't make any products out of it that would be useful to others. But if I was on the consumer end of it, and I wanted a big power Z, VR38 seems (reluctantly) a better move if starting from scratch anyway.

If I only would have known back in 2018. LOL, the starting over is the sucky part. The chassis becomes a handful at 900whp+ on the street. That's why I kept the VQ. Very few folks have driven a 370z at that whp.

Spooler

I am confident on where I am right now with my car. I made just about 900whp at only 23psi of boost. My turbo kit is very efficient now. I have more turbo room. My drive pressure ratio is only at 1.11 to 1. I have learned a ton and have my crap together this time. I am in no hurry.

Spooler

The VQ35DE guys are lucky. Mazworx has a Billet Wet block for them already. All the guys running DE's have an option. If Mark sold some of these the VHR's would get done.

Folks could be out doing this or faster.

Make no mistake. A billet block motor can have issues also if care is not taken in the tuning, turbo kit building, and turbo selection.

shadow85

so anyone going ahead the the VQ37 billet block?

Speak to Bullet Race engineering here in Australia, they said they will do it if they get 5+ customers on board.

Bullet Race have a huge reputation in Billet blocks on other platforms, they ship world wide.

Spooler

I would be interested in one. Ryan may be also.
