Have you tried advancing the inlet cam? will cost you up top if you go too far.

The connector on the tps is an idle switch for the stock ecu. The one with the wire is the tps sensor.

All RB's have constant power to the injectors. If your ecu is a wire in model then it drop its outputs to ground whenit is off. The pnp vipecs dont have this issue.

I used a Motec DMC. My ECU has a speed input that I can calibrate though.

Did you put a restrictor in the VCT oil feed? This is only needed for non Neo type cylinder heads. When the VCT switches on, the head will flood with the excessive oil supplied and push out the breathers. 1.25mm is the restrictor size in the R33 RB25 block from memory.

Its not only the inlet valves that see boost pressure. Exhaust manifold pressure is similar to inlet pressure.

Which 25 cylinder head? If it's a R33, what size line and/or restrictor is going to the VCT gear?

I fitted a set of Performance springs and retainers to my 2.6 Neo. Handled near on 2 bar fine, although the car has only done about 4 k's in 2 years.

Email addy?

I have a newish bride seat rail for R35 GTR. Part # is N111. Side mount adapters too. Located Perth WA. $200 Plus postage.

LOL... That is the incorrect bolt/washer assembly. Also the origional bolt is hollow down the centre to let the oil through into the gear.

Broken engine mounts??

Blue with a white trace, is the power supply.

No one mentioned cams affecting results. More overlap = less static comp.

85 connect to ign 12v switched 86 connect to pin 18 on the ECU header or ECU fuel pump output 30 is a fused power supply from the battery 87 is wired to the positive side of the pump This is the correct safe way of doing it.
