Hi I got some RB26 cams and adjustable cam gears, which I fit recently,
This went into my RB25, I first pressed all the oil out of the hydraulic lifters and re fit them so that they can self adjust to the new cams.
When I put everything back together, the start up was very difficult, I had to keep the revs on 2000rpm but the car kept on dying below that.
The engine sounds like it is miss firing and it is down on power also.
I did a compression test but all the cylinders was 800kpa plus
I checked the timing mark almost 300 times already, I might have turned the engine over 200 plus times by hand to verify that the marks are dead on.
The adjustable cam gears have been set to 0 at the moment
Spark plugs is working
I do not know where to start looking next, injectors and that should be fine as I did only the cams and gears
