Very nice but I thought GTM did the first setup
But that is a clean job.
|
I wonder how the F/I section will turn out over here....
Forged did a great job on that G37!! |

WOW...
That Engine is beastly... GOSH! I must save even more money now since it reminds me I must twin turbo the Z! |
wow thats so sick!
|
Quick question...
... but how much boost can be reliably pumped into the VQ37VHR? What are the internals like on the mill? |

What fuel? 93? I just don't think this will last than a couple of weeks on that high of boost at that CR.
Did they change the pistons? |

It should have no problem lasting, but it all depends on the owner of the vehicle. Look at the VQ35DE. It is considered a "higher" compression motor, and there have been 350Z's that have been boosted for 30K miles +.... time will only tell. |
I'm no expert on VQ motors just yet, but 10PSI sounds a little high for a "high compression" motor.
Also 12psi is barely, if at all, in the efficiency range for a twin GT30 setup. They must have been planning to crank that up a bit in the future like the owner wanted. They could have made 12psi with smaller less laggy turbos. Good to know though. |

Safely on stock internals?

It all comes down to driving habits. Are you the type of person to take it to redline every single time then shift? Are you more conservative and shift at around 3500-4000? Remember.... your car doesn't go from vacuum to 10psi instantly; your car builds boost over the RPM range. If your shifting @ 3500 RPM, your car may only see 4-5psi. Driving habits will determine how long it lasts. |
hehe yeah, I know a thing or two about turbo cars. I understand what you mean, with the 6psi safe and the 10psi somewhat safe. its the same when you run an sti between 18psi and 21psi.
And I'm definitely not on the conservative side, I dont redline it all the time, but I do drive it hard often. I'm definitely concerned with reliability. Thanks again for the info Slidefox |
I don't think that's the first one. There's a member that goes by the name Fireboy on the myG37.com forum who TT his G before forged did.
and there's another member that radically changed his G around the same time as Fireboy |
I have very bad experiences with FI BEFORE building the motor. Very bad. Then again, I drive like a bat out of hell every day. so I agree, how you drive builds is a part of it.
BUt any FI on a motor will end up killing it in the end. the question is how long. I personally wont ever turbo or supercharge a car again before Ive rebuilt the entire motor. |

:rofl2: J/K man! I am not a FI guru but I can def tell you that you should def research your engine. Find out what it can really handle. If you're going to take your engine to the limit (which happens 90% of the time because going fast is an addiction), better build up your engine first. |
HAHA. They actually have sanctioned competitions for that type of driving, 1st place taking around 40K (US Dollars)
I understand you cant be general, but even on a stock turbo charged engine, too much boost will kill you. My 96 eclipse is a prime example. Made for boost. I went boost happy, Killed the motor. My charger's motor blew without boost. the higher (slightly) RPM did it in. In the end, more often than not, you will be a far happier camper with a fully built engine before your FI than after. |
Oh yeah, well I meant stock boost.
I know all about that, I was tuned for 23psi with a 35R on a stock STI block. Umm, bang! Yeah, I'd really keep it safe until I got some internals in there. |
Hi everyone! Thanks for having us on the370z.com forum. We are looking forward to building some very impressive 370Z's. Since the G37 shares much of the same drivetrain and suspension as the 370z, we are pretty much ready to hit the ground running.
Someone had asked earlier about the power and boost limitations on stock block VQ37's. For now, about 10-12psi, and 500whp is a very good safe limit. This is about 100whp more than we recommend on stock block VQ35's. Nissan did an incredible job strengthening the block, crackshaft, and rods. Unfortunately, the pistons, IMHO, are still a weak design, so we have to be careful with how hard you push the engine. Like all things, time will tell, but this engine is a quantum leap forward in engineering and design, and we are excited to be among the first shops to work on them. |
Almost sounds too good to be true. 500whp on a stock block...
Can't wait to get more info on this... Also Sharif, if you need someone to do some independent testing of your products in the florida heat. PM me ;) |
^^^
Yeah yeah yeah yeah Miami uh uh Southbeach bringin the heat uh Haha can yall feel that Can yall feel that Jig it out uh sorry, coudnt help it...lol |
Looks impressive.
I'll hopefully be re-joining the Z ranks and joining the boosted 370Z ranks sometime next year. I'll be giving you guys a call if and when that time comes. |
I will be also boosting my 370z :]
|
Very cool guys! You will love VQ37 TT's!!!! Very fun high reving engine.

I just really hope that there will be a plethera of smog legal forced induction parts for us cali guys and gals.
|
How is the car handling the power Sharif?
|
Are there going to be any smog legal turbos out for this engine, because this time I really want it all legal over here in Fresno.
