| Have your drivers door open, turn the key on to ignition and within 5 seconds press the door light switch 7 times. This will reset it. |
| Skyline 02 sensor operation and replacement |
|
Check and replace 02 sensors - they have a limited lifespan and they die after around 50,000kms ish and the part is about $100.
The 02 sensor is solely responsible for getting good fuel economy. With a good setup you can have plently of power and 400km's to tank each time easily.
If you were getting less than 300kms to a tank, then 02 sensor is toast. Over 300kms to a tank is fine. stop loading the engine up and stop bringing it on boost, problem solved. If you dont believe me (or others who have said the same) give your car to your girlfriend or mum to drive for a week I bet they get over 400kms to tank. Also what do you classify as "to a tank" are you measuring the same way each time. Do you run it empty? Do you fill it up to the top? How many litres do you fit in when you "think" its empty The GTST fuel gauge goes past E before you are empty and then the idiot light comes on. The difference between near E and past E is around 40kms (at least) of light cruise. The 02 sensor is usually the most common thing to be the cause of poor fuel economy and as most work shops / services wont ever check it etc and theres no idiot / warning light that comes on when its dead so you would never know if the sensor is dead / lazy - The car will just run like normal. You can find a replacement 02 sensor to suit ECR33 from your local repco etc. The same sensor matches the ford falcon EL which is a generic 3 wire 02 sensor. Be sure to note, you must cut the wires and fit it yourself, it doesnt come with a plug |
| Head Porting for the RB20/25/26 heads |
|
An alternative opinion, why not………..
RB heads (all of them) are NOT as good as some people would have believe, they have daggy castings, rough edges, unequal port dimensions, different sized combustion chambers etc etc. Sure you can make lots of power without porting, but you have to run MORE boost to squeeze that airflow through the small ports. MORE boost, that means MORE retarded ignition which means LESS response MORE boost means SLOWER boost build, advancing the ignition will give FASTER boost build. MORE boost means you need a bigger intercooler, to take that EXTRA heat (caused by the compressor working harder) out of the airflow produce by the compressor. A SMALLER intercooler and pipework means FASTER throttle response So after porting, you can make the SAME power at LOWER boost, with MORE response, FASTER boost build and QUICKER throttle response. At the same time as he is porting it, a good machinist will equalise the combustion chamber volumes, so that the compression ratios on all 6 cylinders are exactly the same. Service the head, new valve stem seals, check the valves and guides, cut the valve seats, set the valve spring seat pressure etc etc. . All of which is essential for a reliable top end. Plus he will match port the inlet and exhaust manifolds, which on its own can make a huge difference So why wouldn’t you port it? Cost, well it costs less than a mega intercooler and its pipework. Inconvenience, yep you have to give your cylinder head to someone for around a week, which is not that long in an engine build. Seems like a small price to pay considering the benefits. |

Rule of thumb for Air Flow meters RWKW & Engine BHP
Please note there is lots of speculation around the Q45's in single or twin form. These seem to be a hit and miss. I think there are two models for the Q45 AFM. They have similar part # ranges and look the same, but we suspect they act very differently. We have seen a few examples of members who can't get past 230rwkw with a single Q45 so it's unclear which is correct. If you are using a Q45 and making lots of power we would like to hear from you. We are interested in the serial # or part #, a photo and how your tune is setup. Email me if you are using a Q45 to Paul |
