The engine in my car has gone through a lot and has held up great. I have over 240 dyno pulls on this engine with the Greddy kit on it, to put that into prospective that's over 30 minutes of WOT dyno abuse. That doesn't include the thrashing it gets on the street and the few track events it's seen.

Another thing to consider is even the best components can become paper weights in the wrong hands. Attention to detail in measuring, machining, assembly and tuning are all vital.

 

Yes to both questions, this a stock greddy kit.

 

Standard ARP main and head studs.

 

Wow I thought you were talking about stock HR headgaskets. So you think with a proper tune that the DE headgaskets are good for 4-500whp long term?

 

Thanks guys...I know the Injected guys stepped up their front and rear suspension when I saw them run in the 8's, and the car was like on a rope going straight down the track without a wiggle. Looking forward to your results at the track with the power your putting down, because I will be doing about 725-750 once I switch out my tranny. Thanks again

 

When you have a lot of wheel spin and or clutch slip the dyno won't show the graph with a rpm base. Here are some general data points though.

RPM/MPH
3K=53
4K=71
5K=89
6K=107
7K=125
8K=144

 

+1 congrats

 

standard ARP head studs......you give me hope brother...........i guess as long as the tune is safe and solid maybe there is no reason to L19s..........because i have heard of a few guys on here running ARP standards pumping well over 19 psi of boost and nitrous and they are lasting.............OP did you deck the head or anything or is everything untouched?

 

U have to be more careful with the Std APR studs.... a solid tune with a good standalone (vpro, proefi, haltech, motec) i am sure the standard apr studs are a great option, butfor you to say that you dont need L19s you need to provide more details on what powergoals you have, and what ems you are running.

Then again, intense widebody g35 has ran the standard Apr hardware at the track for quite a few passe @ 18-22 psi, daily driven at about 15 on a gt37r. No issues but its running a standalone ems and a proper fuel system too.

 

Just to be totally clear, when you say a "proper fuel system", I'm assuming you mean at least an upgraded fuel pump, a regulator, rails, and injectors?

 

^^ Intense is running the Powerlab Twin In-Tank Pump Assembly

 

yeah as mike says i am talking about the twin in tank but i wanna be clear that i mean proper for this powerlevels.

 

Everything was untouched. I just checked heads for straightness and cleaned the mating surfaces. On the block I just did a light hone, and installed a set of standard bore 8.5-1 pistons with some Pauter rods. I also used the standard ARP main and head studs along with stock Nissan engine bearings and headgaskets (DE) This engine has been in my car since 06/2006 and has about 20,000 miles on it.

Things to consider for engine builds...

-Budget
-Realistic intended use and expectations
-Engine builder
-EMS and tuner

Search to see what has worked for others and then consult a professional. Don't be afraid to ask questions about their recommendations. Things usually cost more for a reason, but are not always need for the given application. Don't believe everything you read on the internet, it's often the blind leading the blind. Look for actual results.

 

I may have missed it.. but what PSI?

 

on the dyno chart

 

If you look at the lower half of each dyno chart you will see 24 psi.

Congrats Ray this is outstanding.
Keep up the good work/research. 240 - Thats a lot of dyno passes...Daaaammmmnnnn!

 

well, after talking to a few different people including ARP, my personal belief is that the headlift problem is not a result of boost psi, whp, or cylinder pressure but infact due to detonation....so if you get a good solid tune with a A/F alittle on the rich side and keep the timing safe you should be fine..........on my car my goal is mid 500'swhp and i'm running standard ARP headstuds, Utec, 750cc injectors, walbro 255lph, and the AAM fuel return...........right now with my last tune i got 460whp at 14psi, which according to my tuner and alot of people i discussed this with say that if i get rid of the 3" single path and go to a true dual exhaust and get a plenium spacer i should be at my goal.........my A/F are at 10.9 at WOT..........i just think that the standard ARP studs became alittle bit of an escape goat. I'm not saying that the L19's are not better because they are they yield 50,000 more tensile than the standards.....i'm just sayin that the standards will hold just as long as your not over the edge with you tune!!

 

correct... thats why i made mention that its running with a standalone EMS and a proper fuel system

 

Oh damn...Now your gonna make a brutha turn up the boost in the beginning of the summer aint ya??

 

Summer starts in 2 weeks
