I GOT RESULTS BACK - I am suprised with the results and Matt done a great job....

234.9RWKW@11/12psi.( I dont know why it ran the higher psi as it has an rb20 acuator on it.

Only issue I had was with the spark plugs, it was blowing out the spark at this boost level, there copper and were gapped to 1.1 now Matt regapped them to 0.65.

He didnt mention anything about fuel, afm or anything and they were working quite well at this boost level..

I am curious to see what it will do when i finish what I want to do with it, just a few more minor mods.

AFR's were good to between 11.8 t 12.0.

Well done

i like more auto's having a crack.

good effort on safc etc but that turbo is certainly a pig.

The Auto Hack Paul was talking about isnt realy a hack or anything technical.

simply un plug the brown connector down behind the drivers side head light and it will lock the trans in 3rd gear.

once your finished on the dyno plug it back in and away you go. 1st , 2nd , 3rd..

i notice your dyno was done in drive so it might explain the massive loss in midrange, as he would have to go very easy on the throttle so it dosent kick back to second. thats of course assuming he dosent know about the brown plug.

attached is my old turbo and my current turbo

both running rb25det auto

if you compare midrange power at say 100kmph your not even close.

but both runs on my car are with a PFC but i still think your turbo may be dragging its feet a little..

cheers

Dangerman,

Yeh he was taking it easy until he would reach a certain klm so it would not kick back, it was constantly kicking back on the dyno...

THe turbo is good for what it is though..i know its no gt30 but I wouldnt call it a pig...on the street im pretty sure im gettn 11/12psi by 3000rpm..

it is annoying though as first gear is wheel spin time.....

I would like to get it run again to see its proper power band...i say ill do it at the SAU dyno day, take that brown plug out..

Midrange does suffer a little on the dyno graph but I dont think its reflects this when drivin in real life conditions on the road..

I would get a PFC if I had the money, but as you can see per the mods I havnt spent much at all..a budget build you could say..

Im still wrapped with the power...

Cheers

Does any1 rekon the boost 98 from united helped me along at all...

Im quite interested in fuels and their advantages and thats the reason why I choose the boost98 as it has sumting like 5% ethanol in it...Ive read quite a few articles claiming its miracles, the ethonal that is and how it has to be tuned to it...

Before I got it tuned i used bp 98 and boost 98..untuned the bp98 felt way better, the ethonal decreased power.

I wanted to use shell v-power racing but I cant even find it in sydney yet...

Let me know your thoughts...im still wondering why the power was so high..the dyno is a pretty average reading dyno(DD) aswell.

Cheers

Looks like a BOOSTD style Hiflow, low boost and cliff like power curve. VG30 rear housing and a highflow front wheel on the stock RB25 turbo.

REV210, what are the specs or how do these BOOSTD turbos rate? all I know is that the previous owner said it is rated at 450hp?

Also with the power curve I dont think it represnts it well as the tuner had to bring it on slowly to avoid it kicking back a gear..I will do the mod where it locks in 3rd gear on the SAU dyno day and then see how it goes...

Also you know the goods on fuels, what is your view on BOOST98 from united petrol..did the ethanol help?

Cheers

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that

      S1 rb25/s14 starting problem

      By MBS206 · Posted

      I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.

      S1 rb25/s14 starting problem

      By Duncan · Posted

      Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required

      S1 rb25/s14 starting problem

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi
