Huh? It's pretty easy to get 225kw out of a RB25 dude
If you are refering to a stock turbo, then that power figure aint going to happen without a bullshit dyno reading.
I agree with Beer Baron. Why go through all the headaches?
Unless you could build half the engine yourself and get parts cheap than go for it. If not, i wouldn't bother.
Another wasted spark and leads conversion thread. Why go down this road? It just isn't needed.
Also, mixing spark plugs really isn't a good idea. Is it the exact same plug (gap, tip position, heat range, resistor type) just an iridium version?
If you do decide to take the head off. then to do the job properly you will need:
Workshop manual (Most important thing, without it don't bother because you will need all the torque settings)
Harmonic ballancer puller
10mm allen key socket.
Full socket set and all your basic tools
Torque wrench
Razor blade (to get the old head gasket material off the block)
Headgasket (or just get a VRS kit and do all your seals and gaskets while your at it)
Deck the head
New head studs
Engine Oil
Coolant
If you haven't done your timing belt and idler do that at the same time.
That's all i can think of for the time being.
Honestly i don't see how they could foul the plugs up that much in such a small amount of time regardless of what they did.
Also, the fact you have to run 0.7 gap even with splitfires is indicating something wrong; mine doesn't miss a beat on 0.8 gap and i run 1.5bar through the same turbo as you.
Yep looks like a copy to me.

ID plate doesn't have any black KKR writing and the actuator is slightly different.
I was under the impression you couldn't run an adjustable cam gear on the stock VCT cam from a RB25. You needed either an RB20 cam or an aftermarket cam which isn't made for VCT.
The VCT cam has a bolt that runs through the middle of it, non VCT cams have four bolts on the outside.
Hmm never heard of those UK nitrous systems. Are there Aus suppliers of those Highpower Nitrous Systems, or do you have to buy direct from the UK? If so, wouldn't the price be a lot more compared to your generic $800 NOS, NX wet systems?
Yep HP@wheels. (RWHP)
Only way you can get engine horsepower on a dyno sheet is if the engine has been out of the car and put on a engine dyno (highly unlikely).
You reckon it's worth mucking around with the water-meth if you go the nitrous? How you going to setup the car with both? Have the water-meth kit switch off when the nitrous kicks in?
