no there is no FI for the HR yet! and as far as the DE it all depends on your particular engine some more some less there is no real anwser there is alot of factors that go into it !

It's not about PSI... there's so much more to it. 500psi on one turbo can be 10psi equivilant flow on another turbo.

And plus, NO ONE HAS DONE IT YET. Trust me, if someone has, it would be all over my350Z.com. Just wait.

Dude, you are missing the point. The amount of boost pressure any engine can take is gonna be relevent to the turbo that's pumping that air into the engine. All the turbo kits out there use different sized turbos, so they're all gonna differ on what a "safe" PSI is. There's no one answer.

Example - My car with the stock 16G can take 30psi no problem on the stock internals. If I try doing that with a 42R I'm gonna have problems. Same boost pressure, retardedly different cfm's.

If you can't understand that, you have bigger problems than thinking about "How much psi can a Hr motor handle???"

Try this:

Find a turbo kit you're interested in (since I don't know what kit uses that exact turbo)...

Go to the FI section...

Search.

And why are you now asking about DE engines in the HR section?

Thats pretty much saying well if a bird can fly, I would assume a dog can as well!

YOU THOUGHT WRONG!


As for safe boost, I leave you with this, take your 350Z if you own one, to a shop, say i want a custom turbo kit because I am a badass, hand them 15K and let us know.

otherwise You Fail!

except for the fact that almost the entire engine is newly designed....so no your statement could not be more wrong

That statement is the opposite of correct. No one knows what the HR can handle yet. Speculation was that it might be able to withstand more than the DE engine. But until someone boosts the shit out of the HR, we won't know how much it can take.

DE!...HR! two totally different ball games; for starters the HR has a higher compression ration of 10.6:1. The DE has a compression ration of 10.3:1. Both of these are different which means timing is different as well. Not to mention, lower compression is ideally better for a turbo set anyway. Which doesn't even begin to justify running higher amounts of boost.
You should also be asking yourself if the internals(mainly bottom end) is capable of running higher amounts of boost. I would venture to so NO because if you use the guy on this forum that had 13 psi on stock internals...he blew a rod strait through the piston.

Let me know if I am loosing you!

Also, to make things more complicated you have to consider because these motors are slightly different slapping on a DE turbo application to an HR is not exactly the best idea! Why? you ask: The power caused by combustion is meant to be produced in a relatively smooth manner expanding gases as a result of burning the fuel/air mixture. If you put on the wrong turbo application without proper setup and computer adjustments you will experience the wrath of Detonation and Pre-ignition. Thus, creating a giant paper weight for your garage.
I'll let you figure out the rest but if you are willing to take the risk and not wait it out then more power to you. I'm not saying it can not be done, but I think if it were up to me I would wait for companies that have been designing FI systems longer than I have been alive!
