Nismo releases new Vq30DE head?

I don't know how knowledgeable Sarah is, but 12:1 compression ratio sounds interesting. This has probably been posted already, too, but since I haven't been on the boards for a while, and the search is not up, I thought I'd ask.
Anyone tried it? Speculation?

Now this is an interesting development if it comes to market... neat article.
"Nissan Motorsports just released a new head which has the VQ30DE chamber volume but the VQ35DE ports and titanium valves which raises the compression ratio to 12:1 if you’re interested in building a naturally aspirated Maxima."

jus curious, why wouldnt it run/run well on pump gas and would it be ok to use that home made race gas( found it in the stickies)

then why does the S2000 run a 12.5 compression ratio but run just fine on premium 91 octane....in other words I guess to put these heads on we would just have to find a balance between retarding timing and the compression ratio to push the limits of premium grade octance gas....

Yeah, check the stats on an M3... really high compression and runs on pump gas. I'm running 10psi on a 10:1 on about 93 octane. Stock advance. I'm not saying it is reliable though.

Ive made calls about it and its designed for VQ 35's so upper and lower intake manifolds for the VQ 35 would have to be used.
I wish there was one made just for the VQ 30.............

Hi, I'm wondering... they seem to have upgraded the valve train, so would we be able to rev higher and still be safe? I would love to be able to rev up to 9k rpm with my max... about the gass I won't have a problem with it, I allways use RON 98 fuel, and allso have access to 100 RON gass if I go to germany and throw their version of Shell V-Power in the max.

J&S Safegaurd is a given if you were to do this swap.
Honda S2000 has an 11:1 CR
Toyota Celica GT-S and Matrix has 11.5:1 (patheticly high CR for hp output)
I would be very careful running boost on stock blocks but then again I would not want to own much less turbo a Celica or Matrix.
A 12:1 would be pretty high for stock ignition timing but with 93-94 it would be possible on pump gas with J&S. The maxima needs 91 but 93 doesn't hurt.
