After fitting the general grabber at2's one thing became apparent, they are larger and do suck a bit more fuel to get moving, so attempting a few things on the injected tb42 to help its cause.
Pulled the extractors off to find that the ports are poorly matched.
Thanks to the carbon build up, I had a template to remove some material and prevent this area of slight blockage.
The extractors came with the oxygen sensor mounted on the cylinder 1, 2 and 3 tubes only, so I welded a bung onto the bottom so the oxygen sensor can get a proper reading of what the engine is doing. Ignore the bad welding...
Am also in the process of wrapping the exhaust in heat shield tape as well to assist in lowering under bonnet temps and increasing extractor efficiency.
Have read the pros and cons of the heat tape, so this is trial and error and will find out for myself what the outcome is.
