Sweet. I'm getting turbo envy and my bank account is not making me smile and say ok

Time to start making ramen and cheese quesidilla's for the next 6-9 months so I can maybe afford a PF turbo.

 

haha

 

if you could post the results here, that would be awesome

 

So to ask a question that is slightly OT but close enough for me to ask.

GTM took the G37S to pretty high numbers and I would expect PF will take the HR to some decent numbers too. Both engines have significantly stronger rods than the DE's and they both have higher compressions than the DE. So has anyone just upgraded the rods and kept the stock pistons in a DE? Or at least put back similar compression pistons?

 

Once it's open you might as well throw in some upgraded pistons. It would be a waste of effort to reuse the factory pistons.

 

yeh these arnt 4cyl engines u can strip down and rebuild in an hour. Factory pistons are designed for NA, so the ringlands are going to be small and near the tops of the pistons. Its just asking for them to break. If the rods didnt snap, the pistons would.

 

we dont cut corners at all, we do things correctly. you need to upgrade pistons and rods every time...

results later today...

 

Umm no. It's the strongest. Reason why one vendor here has gotten over 550 to the wheels and still going.

 

Wasn't that on a VQ37HR?

 

It's the same damn engine. The rods are 95% the same except one little mark on them.

Again the HR is much stronger than the DE. It should be able to handle almost if not the same boost as the 3.7HR

 

It's still larger damn displacement.

You're making assumptions. For all anyone knows they could use a weaker rod bolt that makes it every bit as sensitive to boost as any other VQ motor. I'd rather wait to hear some results from an actual boost VQ35HR.

 

I agree, but at the same time am expecting to hear 450ish whp from 8psi and it be considered safe.

 

We also have a kit for the VQ35HR that is being prototyped on our 07' 350Z.

Currently both kits are available for sale, but only for in house installation and tuning, transportation services are available.

As soon as time permits we will wrap up our 07' 350Z test vehicle and post some results as well.

Good job picking up sarcasm....

 

man, that sucks, i'm in kansas and can't give up the car for transport--its my daily driver.

 

The company that did the G37 had parts from the VQ35HR and showed pictures comparing them. The only difference they saw and showed us was the end of the rod a small difference. The rod itself was exactly the same as the 3.7HR.

Please stop spewing bs and do some research. It has been discussed.

 

Discussed, but not proven. Why don't you stop spewing assumptions and generalizations and show me some dyno sheets. I know you want to believe your car is the end-all-be-all of Z's, but I'm not going to take someone who has no proof but a few photos of pistons and rods.

Why don't you do us a favor and install some turbos real quick, crank up the boost to 550whp, and hope it doesn't blow before coming back and getting your panties in a wad?

I'm not sure why all 07+ owners believe that they're king badass just because they bought a late model car.

 

See post 20

 

So how can a HR not be stronger than a DE when the rods are twice the size of the DE? How can the HR in the 350z not be as strong as the HR in the G37 if the rods are the same? Time will tell, but facts are facts that the HR is stronger than the DE and will handle more boost. Your the one spewing bs saying it won't be as strong.

Some of us have owned all models of the VQ...I have you have not. So go away.

 

The difference between the two HR rods is more significant than you are making it out to be. I wouldn't want to throw too much boost on the stock block because of the pistons more than anything.
