Hi guys just to put the record straight, I have known Jeff for about 13 years and he would never rip me off which is why when I had my car I only had him do work on it. The injectors Jeff acquired for my car were definitely not cheap chinese crap, when my engine was finished it was running so perfect with absolutely no shaking, it was very smooth. Now I was putting shell petrol in my car since I had the engine build but this particular day I went to Asda and filled up with normal 95 ron , only recently I thought about this, because it has been bugging me, this I think is what killed 2 pistons. If the injectors were bad from the start why would my engine run so perfect? It was definitely bad fuel I stupidly put into my car, lesson learned, never put normal 95 ron in an upgraded engine.
dan300zx sorry but there was nothing wrong with the injectors, your tester got it wrong in the first place by saying the injectors were cheap chinese crap and may also have got it wrong about the flow, I definitely wouldn't bin them without a second tester checking them out.
