Cheapest - replace the headgasket (check the head for warp). 2nd cheapest buy a second hand motor Long term solution - rebuild your motor.

$400 is pretty cheap!

Good buy! Putting aftermarket xenon kits into headlamps not made for them is usually illegal because the mismatch can cause annoying glare to oncoming traffic.

O2 sensors need to be replaced regularly but it is rarely the case that they make a significant difference to fuel consumption. The main problem is usually the right foot plus RBs run rich from stock which is why it is worth Nistuning even a fairly stock engine.

I have the same problem. Pretty sure its not the heater core as the coolant level is not going down. Most of the water comes down the LH side - must find the aircond drain and maybe the drain from the sun roof but it could be something else altogether

I'm getting 600 km to the tank with no O2 sensor and an RB30!! Actually a freak result. I had to drive down for a track day at the Manfeild Circuit near Palmerston North on Friday and for reasons too boring t relate I had to (a) stick rigidly to the 100km/hr speed limit and (b) drive economically so I did actually get just over 600km out of it (and that's without emptying the surge tank which holds another 4L) so I worked it out at close to 10.5L per 100 km. To do that I travelled on average between 95 and 100 km/hr and only floored it for about ten minutes the whole trip (couldn't resist overtaking a whole line of traffic caught behind a truck) . I think the RB30 is actually an advantage as I could drive in 5th gear virtually the whole time (it pulls well from 1500 rev/min in top) except when stopping in the towns along the way! I don't have an O2 sensor because Link controls it all.

If you have access to a dyno stick it on and see if the mines ecu is right for your car - if it is yippee if not bin it. BTW while the general opinion is that Mines ecus are only good for the car/engine they were chipped for allegedly some are actually tunable so check that before you consign it to the bottom of the sea.

You 'll find out what the coil packs are when you go to change your plugs...each plug has a coil pack sitting on top of it. Look for scorch marks to indicate shorting and search for a number of ways to insulate your coil packs (or if you have money just buy some new ones if you still have the originals). Buy the BCPR6ES and they will be ready gapped at 0.8mm

I presume you are talking about an RB20 - if you look at my chart above you will see it makes full boost by 3500 rev/min on my old RB25

Have a read of this thread (or maybe just the last 10 or so pages): http://www.skylinesaustralia.com/forums/topic/313603-precision-billet-turbos/ They are getting some good results and should have a turbo to meet your requirements. I would be looking at them if/when upgrading.

Sorry guys - seems I got mine at mates rates - my engine builder only makes them for his own engines - says he doesn't have time to make them for general sales.

I can sell you 2 x 1.0mm restrictors. That's what I have in my RB30/25 (with VCT).

I've bought stuff from Kudos - trustworthy supplier!

I got some brand new OEM coils for about $500 a set and am running them at 20psi soon to go to 25 psi. Someone said there are some fake OEM around but mine seem fine (bought them off an Aussie on Ebay).

This is the chart from a GCG r33GTST highflow I had on my RB25DET (I fitted a RB32 actuator and a Jaycar EBC):

I have a Bosch 044 but its really noisy. Are the Nismos more quiet in comparison?

Here's a manual conversion: http://www.trademe.co.nz/motors/used-cars/nissan/auction-511690306.htm

Canman on SkylinesDownunder made a computer with a touch screen for his R34 GTR which controlled the stereo, displayed all the paremeters of the engine (yes I know the GTR does some of that already) and had SatNav and the radar detector built in. I'll put up a link when I find it.

Excellent result! Can you please post up your specs and charts here:http://www.skylinesaustralia.com/forums/topic/52540-stagea-dyno-results/

They are in the S2 Stagea - usually one or two wrecking or converting to manual. Mostly they are awd but it should be a lot easier to adapt one to rwd than to convert an RE4

You say your Z32afms have no filters - they could be duds - if you look around (Google?) you will find how to spot fake Z32 afms. Where exactly are you? If you have a decent internet connection / mobile phone network Guilt Toy (on this forum) has done some successful remote tuning. Or I know a couple of tuners from here (NZ) who go to places like South Africa, Samoa etc to tune GTRs - I don't suppose you want to pay for a special trip but you may be able to take advantage of one of their planned trips.

I don't see many people supporting super spark coils. See if you can borrow a set of new OEM coils or Splitfires and see if that fixes your problem.

If they have RB25 written on in paint then they were second hand replacements. Did they still work? You need to be saving for a new set.

^^^as above - its do-able. Is it cost effective? If you can find a shop that is prepared to stand by its work then get a price and decide for yourself.
