Spent a couple of nights doing: injectors, intercooler pipe work, wiring & refitting the bumper + cross check everything is on tight.
Then spent yesterday trying to run it in, out in the open.
Used the other car in the garage to assist.
Which, after testing, proved the original battery is dead. So a new one was purchased.
Only leak to report was the bottom radiator hose joiner/extender. I have re-used a piece of pipe that I shouldn't have as it looked tired already. I'll put a silicone one on it, but tightened the joiner for now.
Other than that, it idles relatively OK. I drove it down the local farm track and boosts pretty sweet. Seems quicker and stronger, yet I've used the same actuator. I did some research into this and it is based on different volumetric efficiency and force, not pressure... all a bit over my head TBF.
But it drives and that is the main thing.
Needs a wash though - 2 years of filth from the garage.
Next thing is the MOT, new exhaust & then mapping. I've messaged Chipwizards to get something pencilled in.
