If I could spend money again (And enough of it) I'd probably have a 6L V8 residing in my bay with a super charger on it personally...

3.0L all the way. Still not fully tuned. I feel from idle I can pull just as much torque, at around 3000RPM I've got slightly less torque (Not MASSIVELY) but hit 4000RPM and it's all over. I run a quite large turbo too (T04R) and it's just so nice. The old 2.5L needed to be really planted mid corner in second to start to wheel spin (Most of the time a clutch kick) the new one doesn't even get on boost and it starts lighting up sideways with everything identical (Tyres, diff, gearbox etc) except for the motor and turbo change... 3.0L also needs so much less throttle and I can pull away from traffic. jumping lanes etc and having to accelerate. the 2.5L was normally drop a gear and open her up to get upto speed. the 3.0L is quite good in zipping up in speed without needing to drop a gear. The ability to light up on the roll in 2nd gear compared to having issues getting wheel spin with out a clutch dump in 1st, and still no wheel spin in second... 3rd gear still spinning in the 3.0L vs only 1st in the 2.5... 4th gear still spinning in the 3.0L in the wet compared to just starting to spin lightly in 2nd on the 2.5L... Basically... The 3.0L shits all over the 2.5L in terms of driveability, torque, power, and once tuned, I'll rev it to the exact same amount... Revs stress a motor alot more then torque. If I make the same power, at 1000RPM less, I'm making more torque then the other guys, and producing less stress on my pistons/rods. Therefore, more reliable. Same cost to build up either (Forged 25 vs Forged 30) and you still come out with more torque, better driveability, etc.

That pipe, from the return line on your BOV. Put some duct tape over it (Alot) and I bet it goes away. Then, go buy a new return line.

What was the readings on the compression test?

My reference to ride height, was in response to mr Nismo. And I'd be saying your car was one of the nearly stupidly low cars if you only had 110 - 115mm of ride height. Seeing how the legal limit, when completely empty, is 120mm, and when maximum loaded, is 100mm... You had a max of 15mm before you were below legal limit... Something I'd call low. I was simply pointing out, if you read the post I quoted, that a 4" gave more ride height issues then a 3"... Whereas, mr Nismo wasn't trying to state ride height issues with the person running a 3"...

You've got more issues with a 4" exhaust and ride height, then a 3"... And I was talking, perfectly legal road going cars. Not those running screamer pipes or anything. Also, not every 400RWKW car runs turbos or forced induction either. But I have seen FI cars, run with 400RWKW and 3"

Seen enough ~400RWKW cars, with ZERO gain from a 3" to 4" exhaust...

If she's still on her L's, as mentioned, in NSW, she can still drive the Stagea. The restrictions do not apply until she gets her P plates. Also, if you two live together, and it's the only car, you may have very strong grounds for an exemption.

Had same issue when I first bought my car. Had massive amounts of toe in. Sounds like yours could be camber related. Do you have bad un-even tyre wear (Look at your rear tyres before answering this)

Pull your rear rotors off, and inspect the hand brake shoes. Check EVERYTHING hand brake related for signs of hitting. As soon as I opened this thread I thought handbrake.

When you put the car back on the ground, you go around, and push down on all 4 corners HARD so the shocks and springs settle. It's easier then driving it... Also, in NSW, the minimum height the car can be is 100mm, this is when FULLY LOADED. The minimum height it can be when empty, is 120mm FROM THE LOWEST POINT OF THE CAR. But skylines look ridiculous scraping there asses out. Mine sits at factory height... All I want is around half an inch lower.

I put two screw drivers behind mine and just kept "jarring" it, and it just slid of so nicely... They do have to come off perfectly flat (You can't pull the bottom without pulling the top etc)

Pull the CAS and check it. And do a compression check whist you're there.

Running the same plugs, same coil packs, I went from a stock RB25DET to an RB25/30DET with a T04R off the side... Still running at 1.1mm gap with out an issue, and currently enough grunt to have 3rd gear spinning hard before I even hit full torque...

What sort of circuit? Full on racing, against other people, or just track work days, with SAU etc? If just track days with SAU, I woudn't bother surge tanking it. Just keep it all topped up with fuel, and it'll save you money! Edit: If I wasn't so worried with legalities, maybe had a thousand more to throw around, I'd probably throw another 2 044s in my boot, with a 2L surge tank... (Leaving the current 044 as a lifter, and to 044 to feed the fuel rail, of which I'd run split entry single return, with a fuel cooler) Unfortunately, I don't have the extra money to even put a normal surge tank in, with the 044 feeding the rail as it does now, and stock pump as a lifter... I just don't see the point, as I like my limited boot space, and the easier legalities of it, attempting to keeping it look "stock" (Although, the f**k off high mount gives it away... )

Build it 3" It'll still flow enough. Trust me.

Poor wiring. Check all connections and plugs.

If I were racing. Weight is an issue, yes. Doing it my own way for time. I'll leave it how it is. Even dropping the 20 - 30 litres out of the tank for a "race" I'm only looking to save 10KG really... Think about it, you add a heap more weight back in with extra tanks, pumps, wiring, fuel lines, etc etc... If I were racing, and going for every hundredth of a second, I'd have a completely stripped out car. On a car like ours, with full interiors, 20 - 30KG is NOTHING. Especially when you have to start dealing with legalities for road use.

Do you have diodes sitting across your coils on the relays? (Or indication LEDS on the coils)? These remove a spike which can cause the relay to hold on for a while, and cause you other issues. The thing with the fuel pressure... If you slow your pump, you WILL get a drop flow from the fuel pump, at which point, 50PSi will still be made, but less fuel will flow. Eventually as you slow the pump though, you will loose rail pressure. Just because your rail is setup to have "50PSi" does not 100% mean you'll have 50PSi, it just means the max, at that vacuum point you'll have, is 50PSi... So as you lower your voltage, you can have fuel pressure drop, and you will 100% guaranteed have a fuel flow drop. If it worked how you were saying, I'm sure HEAPS of companies would only run at 6volts or so... Your current, is PURELY dictated by V = IR... Keep resistance constant, and your current follows the voltage change. (Volts up, Current up, volts go down, current goes down) The only thing I can think of, is to put a diode in line on each relay... So you'd put 2 diodes in your system... Will help isolate the 2 relays that are triggered from the AFM. May help remove that strange problem you said you had when you switched it off. I'd also be checking what actual voltage you have across the fuel pump when in 7V mark. From what I understand of the the GTR fuel slowing thing, is that it uses a voltage divide, which places a resistor in line also... It's how they work... (not explained properly by me there, but yeah... It divides the voltage by wacking a resistor in line from what i know of the workings of the GTR fuel slower) The only other thing I could think for you to do... Put another fuel pump inline with the 044. You'll need 2 one way check valves. But run another GTR pump in parallel to the 044. And when the voltage goes above 2.5Volts, turn the 044 pump on. When it drops below. Turn it off. Run the second GTR pump full time. The one way check valves will stop fuel attempting to flow backwards through the 044 when it is turned off. And the second one way check valve after the GTR pump, will stop fuel flowing through the GTR pump when the 044 pump is on... |FUEL TANK|------|GTR LIFT PUMP|---|Surge tank|---GTRPUMP---CHECKVALVE---\_______Engine fuel rail... -----------------------------------|Surge tank|---044PUMP ----CHECKVALVE---/ My attempted drawing of how to set them up...

Okay. Go and compression check the engine... That's f**ked...

What do you mean pushed out a kiwi size? Whered it push it out? Pics?

Not tracked it yet with this new setup. Pushed it hard under brakes/throttle, and through some corners. No surge... But I'm also not stupid, the tank holds 65 litres, I won't let it drop below having 50litres, at a time to refill. When pushing, don't do it with less then 35 litres in there. Factory fuel tank is designed with a swirl/surge point in the pickup. Just checkout the design of the factory tank.

Bosch 044 mounted in tank. No surge tank. No smell. No noise. No Surge either. Looks stock, sounds stock, and has no legality issues.

Did you pull the cas out and actually check it? It's very unlikely the cat fouling will make it skip a tooth. Have you replaced the actual fouled cat yet?
