Well, that's not true. If you look at them, and they are yellow, at least 2 of them will be no good.

Why would you want fixed (non twisty) FUCAs when the world now agrees that flexible upper arms are a bloody good idea? ie, UAS, GKTech.

Don't go over 10 psi on an R33 if you don't want the ECU to chuck and emo fit and throw all your petrol into it on every engine cycle. The mixtures are stupid rich on RB25 ECUs when the boost is up, and they also have a habit of giving you the lovely gift of R&R (Rich & Retard) as a built in engine protection feature. The ECU is a much bigger limit to boost happiness on an R33 than the ceramic turbine is.

The oil cooler/heat exchanger at the oil filter mount can break too.

Nope. Adelaide, yes. Knight Engines. Butt not Melbs.

RB25DET NEO Turbo noise normal?
GTSBoy replied to sledgehammer's topic in R Series (R30, R31, R32, R33, R34)
Plastic compressor wheel is very quiet. -
Other way around. Stock is 1.1mm, gapped down means smaller, ie 0.8mm. Gapping them down can (and will) help if the coils just aren't good enough to run against the boost....but these days any misfire should be taken as a reason to upgrade the coils. Yaris, Audi, R35 GTR, etc are all options these days.

That's all repairable. It won't be cheap, but it could be fixed.

Needs better coils.

Fuel smelling oil / fuel and oil in catch can
GTSBoy replied to pogman's topic in R Series (R30, R31, R32, R33, R34)
No, E85 makes condensation. Because of the much higher hydrogen:carbon ratio of ethanol compared to 7-9 chain length hydrocarbons, it simply make a higher % of water vapour in the exhaust gases and therefore you get more of that condensing in the oil. Oil/sump temperature will be about the same regardless of 98/E85 fuel in use. It's the upper end of the engine that runs cooler. The bearings still make a lot of the heat that turns up in the oil, probably more on E85 if it's got more timing/boost/power. But the water is continuously being made. It should be safe to return it all to the sump, because the water should boil off again, but by the same token, if there's enough in there it will sink to the bottom of the sump, get priority pickup by the oil pump and f**k the bearings in short order. So, a large catch can and a very decent breather system that can pull off water vapour before it condenses and send it to be burnt are probably the wisest idea. -
I endorse this product and those who use it.

Mamba Internal Wastegate Diaphragm Leaking?
GTSBoy replied to RB25Detonator's topic in Engines & Forced Induction
I would suggest that you have torn the diaphragm. That hole is to make sure that the back side of the diaphragm is open to atmosphere so you don't get any pressure in there when the diaphragm is moved forwards/backwards by the boost signal on the connected side. An EBC solenoid valve is a calibrated leak from that signal line, so yes, air should be able to pass to the wastegate, regardless of the state of the solenoid (on, off, working, broken).- 11 replies

Running an oil cooler? Might need to be hotter. Any chance that it's simply a bit rich somewhere in the operating range and washing down? -
Help! Rb20det tps issue? Won't idle
GTSBoy replied to Kraaken.r32's topic in R Series (R30, R31, R32, R33, R34)
15° manual, 20° auto. -
The bearings are OK pricewise. High side, but you have to expect markup over what you can get them for yourself. The labour to change the rear ones seems exhorbitant. Over 6 hours? Same at the front. The spray welding may or may not be necessary, and it is outside labour, but it also seems a bit high. The start price is probably OK. The labour for it is probably double what it will actually take. The service at $300 is probably OK.

Removing Poly Subframe Bushes
GTSBoy replied to 260DET's topic in Suspension, braking, tyres and drivetrain
Should be able to recipro them out. You can also use a drill to punch holes in them (if you can access the end of the bush well enough) to remove material to make other tools easier to use. -
Oil Control In Rb's For Circuit Drag Or Drift
GTSBoy replied to Sydneykid's topic in Engines & Forced Induction
That table would probably be better with 1.25 restrictors instead of blocked off for the standard pump cases. That would include the N1 pump, because it's really not that much larger (if at all) than a stocker. Neos have the N1 pump, for example. -
I hate to say it, but it sounds like you have something put back together wrong. Gasket blocking a gallery or other opening, hoses in the wrong places, something like that.

Not sure these will intimidate many motorists
GTSBoy replied to PranK's topic in General Automotive Discussion
Intimidate? In real terms, it doesn't matter what the cops drive. The idea of high speed pursuits is so anachronistic these days that it doesn't matter whether they drive Camaros, R35 GTRs, Passats or Yarises. They will either call off the pursuit because "too dangerous", or they will chase you. The only place you can realistically outrun any other vehicle these days is highways, and helicopters love highways. Helicopters are what the cops are really using to intimidate motorists these days.
