06 350Z Greddy TT Bone stock motor 14.5psi
on the 2006 Turbo xs utec with map sensor, we did our own return fuel system using deatsh werks 800cc injectors and the holley/walbro fuel pump. With the q16 fuel we were at 63% duty cycle.
on my 03 I had the cjm return fuel system with different fittings, also a holly fuel pump, RC 650 CC Injectors on 114octane fuel i was at 97% duty cycle(yes I am nuts)
I also highly recommend having a wideband in the car, I almost force having one in any forced induction car thats modified with any of the installs we do.
I should probably post the numbers by now 627.8whp 629tq with a 1.18cf. Before people start going off on me, look at this first
Rev-up motor with roughly 10k miles, Q16 FUEL, 14.5PSI, STOCK MOTOR SO ITS HIGH COMPRESSION.

My 03 350Z 113K MILES 597WHP 618TQ (1.18CF) 16PSI been boosted since roughly at 75k miles to 113k miles, ran at 9psi for the whole time, till the last i want to say 500-1k miles of when I decided am going to blow it up. It saw drag/track/drift. I parted the car out, still drives around with the new owner that couldn't be any happier for buying it at a good deal(knowing that it was abused in the past).
The car 2006 mentioned above has about 10k miles on it, been boosted for 2500miles, still fresh and has alot more to go.
P.S You guys might not care about this, but thought to throw it in there too to show you that not only this could be done on VQ motor, we also got a 95 Honda Civic hb with a bone stock Integra GSR 167k mile swap in it, arp headstuds is all its got, has a little T3/T4 60-1 Turbo, weighed in at 2400lbs on 15psi e85 ran a 10.52@137 with a highest trap of 138mph with over 80passes on the motor. People call us crazy for doing this.

the only car that didnt break was the one with the stock motor. its possible guys. please dont bash because you dont know how we do it or how 500hpZ does it.... just let us do it for your car instead we will be shooting for the first stock gsr motor to run a 9 soon as well. ill post video of the Z soon as long as everyone is nice

ummm yeah you are a little nuts. hahaha. how long have you been running for on your 03 and under what driving conditions. i am very interested and appreciate you sharing the info.

I have a question about injectors guys,
I know you shouldnt run more then 80% duty cycle (hence why they are rated at the HP number where they should be at 80%)
But what is the lowest duty cycle they can run?? Like can you go overkill to allow for growth??

its good to see new goals and limits reached Would you be even better off with a full standalone liek a Fcon or haltech??
Why the XS?? any reason??
The driving conditions of 40-155mph(plenty of it), bad fuel pump/bad fuel caused me to get into 15:1 a/fs. Drift event (I had a driver for the car who got 1st place), at the road course I had the instructor drive to see if it will blow up, it didn't. I even decided to stay in it at over 13:1 a/f the night I had bad fuel just to blow it up, it didn't. I blew a clutch, blew 2 transmissions, broke both axles and the motor survived.
It would even be better with a haltech or fcon no doubt, but how many can afford either one of the systems? To sum it up, we did this to show people that if a shop is trying to sell you a hks fcon to make 400whp is ********ting you.

Does that make sense?? Or am I wrong here??
If you're planning on building the motor later yes, wouldnt be a issue to buy a decent system. Reason behind my post is to comfort alot of the z/g owners who are wanting to go F/I but fear blowing up the motor because they refuse to spend thousands of dollars on a managment system, to where it could be done on simple systems (NOT THE EMANAGE) with a good fuel system. Having the best and expensive isnt always right, whats right is having the right parts that work together to make power.

why is there so much underestimating of the motor. I mean why is it this motor only from nissan which seems to blow if you go F/i how come the older Z did not have a problem or like the s13 seems to have a stronger engine?

I guess just because of all the guys blowing motors it causes distrust?? But it seems as of late under 450HP hasnt seem to be blowing the motor as much... My guess is as R&D is done on this car higher and safer numbers will be reached

I hope to see some more packages offered soon putting all of this into a bundle.
well there might be a lot of possibilites when it comes to blowning a motor, im not too experienced but a lot fo people say the tuning is important and not pushing over the limit
BTW why did nissan make this engine so weak compared to other ones?

uh i think thats the whole point of this thread....they didnt make it weaker. people have just been blowing them up by being dumb and thats made everyone think they are just weak. they arent when done right and taken care of. 600's on a stock block is not weak.

I think lack of tuning and lack of a proper fuel system seems to be the issue with past blown motors. People not wanting to upgrade the fuel pump or going to a return fuel setup seems to be what the OP is hinting at.
If you spend the money where it needs to be spent you can do it at a reasonable price and be safe about it.

over hereoh BTW.. since his tuning is so superb.. have him warranty his work for a year and offer to fly a new motor and install and tune it for free if something happens within that year.. but i bet he will say your motor wasn't one of the freak motors
