    My astra C20XE conversion project

    A much cleaner engine bay, at least compared to how it was before :) Still a long way until finished!! AFTER: BEFORE:

    My astra C20XE conversion project

    I recently started shaving the engine bay. Removing all unnecessary brackets, battery tray, and marking up the holes that need to be filled in. So main loom support bracket deleted. Battery tray removed. A few other bits here and there also deleted and smoothened. I will come...

    In the meantime a few electrical goodies arrived :) Battery tray for relocating and securing the battery in the boot.

    My astra C20XE conversion project

    After sorting out the relay boxes.. the big challenge has began, that is to reroute and hide all the wires from the car wiring loom out and around of the engine bay. All wires coming from the engine bay, including those for the aircon, will follow the path underneath the scuttle panel, then...

    My astra C20XE conversion project

    Going on to the second relay box from the engine (from a quick research that's for the A/C and horn).. That's the standard box that is attached on the bulkhead inside the engine bay. So.. I removed the relays and fuse, deleted the box, and rerouted the wires underneath the scuttle panel. I...

    My astra C20XE conversion project

    So a few of the major things that need to be arranged are the two black fuse/relay boxes inside the engine bay. The one is the main power fuse box which I will have to reroute under the scuttle panel. With the battery going in the boot I had to find a way to distribute the power from the battery...

    Of course the alternator and starter wires will remain in the bay. I will leave them on the side for now and come back to it later.

    My astra C20XE conversion project

    Started removing auxiliaries, like the radiator, power steering pump and pipes, A/C system etc.. And also tackling the wiring! Labelled everything just to keep track of it, before I start plannign the rewiring process. So the plan is to keep the original rerouting in and out of the bay...

    My astra C20XE conversion project

    Coming back to my thread after some time now. Want to carry on with the updates as I go on with the project. So last May I bought a donor astra f mk3. After more than 2 years of patiently searching for one, I finally got one in my hands. A 1.4L, 5door in white colour, with factory AC, and with...

    My astra C20XE conversion project

    Being almost out of thoughts at that point, and nearly 5+ years into the project, we really didnt know what to think more. Shaun insisted that the idle and hard start problems were caused by the high manifold pressure, which was caused by misallinged timing. So, having literally no other ideas...

    My astra C20XE conversion project

    A bit of wiring to make the stepper conversion. We had to delete the idle valve wires and add new ones directly to the ecu board.

    My astra C20XE conversion project

    One of the things that Shaun suggested at some point was to remove the standard idle valve and go for an idle stepper motor, since for some reason he noticed that the idle vale could not be adjusted properly in Tunerstudio. So with a bit of wiring we installed an idle valve stepper motor off...

    My astra C20XE conversion project

    Once everything was properly connected to the car, we could run some first tests to see what was going on. From a first glance it seemed that the manifold pressure that the new MAP sensor was measuring was a bit high. But in the beginning not so much attention was given to it, since as I said...

    My astra C20XE conversion project

    Carrying on with the thread after a few weeks being off! So going on with the troubleshooting process, and still chasing our own tails, I was pretty sure that the problem was down to an electric issue, although I refurbed and replaced all sensors and ecu at least 2 times and also repaired my...

    My astra C20XE conversion project

    Yeah I am still not 100% sure how, but it was all down to a timing tooth being out on the inlet cam.. The problem is that when everything was aligned with the stock timing marks, the car wouldnt run properly. Had to actually do an air leak test on the pistons to actually identify the cylinder...

    My astra C20XE conversion project

    And now the true story began with over 4 years (!) of troubleshooting and trying to figure out problems and problems... So as I said earlier in this thread, the engine came to me with no known history. One thing that I found out at the beginning was that the botom end was from and early 20xe...

    My astra C20XE conversion project

    Big 277mm brakes installed with vented discs. And a set of brand new 17 inch wheels... The car was also lowered on a set of brand new H&R H&R Cup-Kit 50/40mm

    Engined dropped in... Moving on to a bit of wiring... Wiring connected up and piping, exhaust, and hoses also.
