I already sold many parts, if you requiere any references please let me know. For sale are six brand new Bosch Injectors EV 6 CS (high impedance 12 Ohm, top feed). These come with matching plugs and custom made top hat adapters to suit all RB engines. RB20DET & RB25DET NEO - plug & play RB25DET - you will need a Greddy/Freddy Inlet Manifold + top feed rail RB26DETT - you only have to remove the injector ballast (done in five minutes, see pictures, you will also need to do this when using injector dynamic injectors) Be aware that injector dynamic injectors (all the rage right now) are just relabeled Bosch injectors and also require top hat adapters and new plugs. These injectors were originally used by Porsche in the 996 Turbo GT2 (480hp) and other models. Bosch part number 0280156012, max. 8 bar fuel pressure. These injectors are designed to work with various fuel pressures, hence the performance simply depends on the fuel pressure: 453cc @ 43.5 psi/3 Bar (standard-pressure), max. ~400hp, 480cc @ 49 psi/3.4 Bar, max. ~450hp, 555cc @ 65 psi/4.5 Bar, max. ~500hp, 600cc @ 76 psi/5.2 Bar max. ~550hp, 640cc @ 87 psi/6 Bar, max. ~600hp!! A good and matching fuel pressure regulator is the "FSE Motorsport 6 Bar" here or here. Datasheet downloadable here. Every mapper can work with these injectors, same performance and quality as Nismo injectors but just way cheaper. Price is AUD 490,00 including shipping, I paid AUD 1100,00 for them - bargain!. Please contact me by private message if you are interested.

Hi, do you know what type of front and rear differential oils the R33 GT-R "Vspec" model needs due to its rear active differential? Is Castrol Syntrax Limited Slip (old name is SAF-XJ) ok for the rear diff? What to use for the front one? Thanks for your help!

I am still interested to know what kind of compression ratio I would have with the 8.5 pistons....

No one?

The cometic head gasket I have came together with a RB26 complete engine gasket kit from which I used already half of the gaskets. Hence I can't return the head gasket and would like to use it. CP piston data SC7310: Bore (in): 3.406 in. Bore (mm): 86.500mm Piston Style: Dome, with no valve reliefs Piston Material: Forged aluminum Compression Distance (in): 1.193 in. Piston Head Volume (cc): -16.20cc Check the attachment for other data. I couldn't find data for the deck height so I assume it must be close to original with these pistons as their compression ratio is 8.5:1?

Hello, I intend using a 1.3mm metal head gasket with CP 86.5mm 8.5:1 pistons in my RB26. Can you let me know which compression ratio I will have with a standard non skimmed head? All the compression ratio calculators are asking for data which I couldn't find, hence me asking here. Just want to make sure that the compression ratio won't drop too much as I already bought the head gasket but not the CP pistons. Would you therefore recommend running 9.0:1 pistons or 8.5:1? Installed GT2860-5 turbos already. Thanks!

Is such a rewiring for a R33 necessary as it has the battery in the boot close to the pump anyway?

Hi, I changed my clutch recently and now I need to bleed my ATTESA system. I found this instruction but it seems to be R32 specific: http://www.skylinesaustralia.com/forums/topic/161627-attessa-bleeding-how-to/ The R33 seems not to have a white bleeder connector in the drivers footwell? If so what are the difference between bleeding a R32 and R33 ATTESA system? I should add that I have a R33 VSpec.... Also what oil do you recommend using? Some say ATF Dextron II, some say III, others say IV... Thanks!

Thats obvious, but which Pins exactly have to be connected to each other? Edit: Just checked the circuit plan and now it makes all sense. All seven wires have to be connected with each other, I better get a strong soldering iron then.

Are there instructions which of the ballast resistor wires I have to connect together to bybass the ballast resistor?

Hi, I am just about to install ID1000 injectors in my RB26DETT. I read on the homepage of the manufacturer that all ID injectors are high impedance. However the standard RB26 injectors are low impedance and the GT-R has a resistor ballast installed as the stock ECU is working natively with a high impendance signal. Do I therefore need to bypass this resistor ballast? I am using a Power FC ecu... Thanks!

I will be using a Metal Head Gasket. I removed the head to seat the valves, the block will stay untouched. GtScotT, you mean three and not four increments of 47NM (3*47NM=142NM)? Still there doesn't seem to be a consensus here regarding this matter... The final torque recommended by Nissan is lower than the one by ARP. So how come that the head gasket will be crushed more?

Hello, I bought some ARP head studs (202-4207) for my RB26. However I am a bit confused as I am not sure which torquing procedure I shall follow best. The Nissan torquing procedure for head studs is: 1. Tigthen to 29NM 2. Tigthen to 108NM 3. Loosen to 0 NM 4. Tighten to 25-34 NM 5. Tigthen to 103-113NM However the ARP manual states: Following the manufacturers recommended torque sequence tighten the nuts in three equal steps to 105 ft lbs / 142 NM with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT. So should I use the Nissan torquing procedure but torque to 142NM instead of 103-113NM in step 5 or should I follow the ARP procedure (three equal steps to 142NM)? Don't tell me to ask ARP regarding this case as I wrote them already two messages (one 10 days ago, another one 5 days ago) and no one bothered to reply to me. So their customer service doesn't seem to know the solution. Thanks!

Isn't the whole point to measure the exh. temperature before the turbo? So why are you advising to mount the sensors behind the turbo in the dump pipe? Furthermore I don't think that there is a big difference between mounting the sensors in the collectors of the exhaust manifolds or in the turbo exhaust housing. But I rather prefer not to modify my new exhaust housings.
