Yep I remember that, a mate of mine did similar - well more the doing mid 10s and 400kw on a stock motor (with just pump gas, no nitrous oxide, I must add) thing that the crowing and being banned thing :)

This car has flawless victory, however:

that thing is beautiful to watch, so smooth and unbelievably fast...its obviouslly well set up and a powerglide does help i guess but all I can say is....I WANT ONe!!!

 

I assume the only weak point for now is the HG and if that goes I'll replace it on mine, if for some reason it's more terminal than that then I'll likely throw another stocker in its place...

The NEO is a tough bit of gear and I hope it holds up :yes:

 

Agree. If I were running a NEO at your level I would swap it out for a stocker once it failed. If I had more than 2 let go I would consider building from there. In the end you could go through 4 or 5 stockers before you reach the cost of building one properly.

Building a motor and only going for 300-400 seems like kind of a waste though :wacko:

The problem with it is, the motor is still susceptible to any one of so many failure points just like a stocker. Just takes one bit of carelessness or bad luck and then you have a very bad time. Seems like going "all in" in poker.

Hence I give props to anyone with the balls and inclination to push a built motor.

Exactly!

And it seems the Nissan seal of approval seems to hold together longer than a lot of "Builds" you see these days........

Agree with you both guys. I built my SR as the cost to me doing all the work myself was about the cost of two stockers anyway, so it was well justified. Plus I'm hoping to see more than what a stock SR will reliably do in the long run anyway.

Good tuning and good fuel makes a big difference. When that thread was started E85 wasn't really available (and still isn't practical for lots of us today).

Ethanol Content Sensor plus a decent ECU. There really is no argument of "it ain't close to me so I can't run E85" anymore.

In my case with two cars already set up and working pretty well the cost of buying a new ECU, bigger injectors, ethanol sensor and tuning does still make it impractical especially if the nearest E85 is 20-30mins away.

On a clean install I wouldn't muck around and just go for it.

What turbo would you guys recommend for a rb25 running e85.

Track car only!
1000cc injectors

power fc

z32

cam gears

profec 2 boost controller

3.5 inch exhaust

Front mount

Goal is for 8th mile drags!!

So need response and huge mid range performance

dont have a power goal just as fast as i can get down the 8th mile!

Any ideas ?

Been awhile since i posted on sau .The neo out me drift car let go a couple of months ago running 320 rwkw BUT beleive this had nothing to do with the power im under the impression it pumped all the oil into the head and then left the bottom end dry spinning the bearing and chucking a rod.

So got another standard neo to go back in its place this time it will be reciving some oil restrictors a head drain and a 7.5l gated sump to hopefully over come the oiling issuse .

Also thinking of changing over to e85 see what itll make hopefully add some more reliability to it aswell.

Ouch :O

This happend on the skid pan after about 3 mins of 5000 -limeter of third.So it was under some hard conditions.see how the new engine holds up and see what it can make with some fruit juice

Well that explains a bit ;) Nice one haha

i'd say your diagnosis is spot on then! lol

RB's without custom drains and restrictors don't like 3+ minutes of limiter much at all hahaha

Just broke into the 300kw bracket....

R33 Series 2

mods:ViPec ECU

Haltech Flex Sensor

GT3076r .82 Low mount, Internally gated

APR head Studs

Metal Head Gasket

3" turbo back exhaust

Walbro 400L pump

Tomei Cams

740 Nismo Injectors

fuel:E85
power: 450hp [335kw] on 24psi
oil: Motul 20W-50
useage: Used to be daily, making its way to cruiser status
lifespan: had it for 4yrs, bought stock as a rock.
failure: Had head problems in the past when running 350hp on pump98
comments: Gains for E85 was 105hp over my Pump power of 346hp on 20psi.

Next mods will probably be new clutch, injectors & External Fuel setup

Why the upgrade of the injectors and fuel setup? Is it on the limit?

Why the upgrade of the injectors and fuel setup? Is it on the limit?

Injectors are reaching their limit for E85, I upgraded my fuel pump tihs week from a walbro 255 to 400 to handle the E85. More of a bandaid till i have the $$ for a full external setup.

255 fuel pump was maxing out with the car makeing 405hp and a mix of 70% pump98 and 30% E85. to get the full benefits of e85 it needed changing

With the Haltech sensor i can now run any blend of pump to E85 i like and the tune will change accordingly.

Very surprised by overall gains

    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
