I just shipped my G35 Sedan to GT motorsports last night after only having it back from the shop about a week. The motor will now have a fully built block with cams, valves, springs, and the whole works. GT said they have 4 built motors that need to be completed before mine. That means it will be a long wait. Once the motor is built I will increase boost to 10psi daily driver, and have a second map with 12psi for track and higher octane fuel. I have 365WHP at 7psi w/ stock internals before the rebuild.

What do you guys predict for horsepower numbers after the rebuild.

 

WOW! That was fast! Did something break or did you decide to just pull the trigger? No idea on the HP thing but you should be able to pretty much do as you like(within reason) as far as boost with the motor being done. Good luck keep us posted.

 

what turbo system/sc system you going with? I think you'll do high 400s @ 12 psi.. Gluck man

 

365WHP at 7psi w/ stock internals before the rebuild



hmmm I was pushing 410 @ 7 psi with all stock internals thats why I only say 400s.... could be wrong though

 

looks like he has a vortech...could be wrong.

 

These are my mods so far... Also you must consider I have a sedan that is stock 260HP at the front.. So that makes me about 25HP less than you to start with. Also I have a automatic which will drop HP numbers. Pulling 365WHP at 7psi is damn good. The kit originally comes w/ 8psi and gives you 412HP at the front; about 330WHP; and I am running less boost than stock.

No I could not wait any longer... Figured why not just build it now, why wait till it blows.

 

good idea. I have the auto tranny also and 25 hp loss b/c sedan? dude I dont know where you got that from. 365 @ 7 psi is good bro. Im not tryin to put you down or anything. Our cars arent really what they are advertised at. I dunno if you no but the G35 Coupes dyno at 248-252.

 

Your question is a bit one dimensional here, but I'll reply as best as I can...

With 12 PSI on a fully built motor, which i'm assuming includes forged internals, better valvetrain, etc.. you could potentially see 450 rwhp without a problem.

If you run 14.7 PSI (one full bar) with a very well tuned/built motor you could potentially see close to 500 rwhp again, without too much problem. I believe anything past 500 rwhp and you'll begin to need some more aggresive cams, more machine work, more boost, bigger turbo, etc... and some race fuel.

I've yet to see a 1000 rwhp 350Z or G35, but I'm sure it could happen. The RB26DETT motor is capable of 1000 awhp without alcohol injection if that means anything :P too bad the VQ itself doesnt quite live up to expectations of the previous RB motors.

 

Can you post a dyno of your sedan at 410WHP at 7psi. And is it a twin turbo or supercharger?

 

The motor is 3 years old. How many years did it take to get the RB26DETT to 1000awhp? Anyways SGP has come close and probably could have done it but the owner did not want any more. They maxed out their dyno at 820whp at only 20.3psi and the car was set up for 30psi. The owner didn't want anymore after driving it with 20psi and told them it was good.

 

How about water injection and 12 psi daily driver?

 

I hear ya man, good luck with everything!
