  • Astra mk3 Arctic 1.6 8v to 3.0 24v build

    Thought it was about time I started a build diary on this as I’ve been planning it for the last three years while I’ve been doing the GTE. Sorry it’s not a mk2 but as this site is so good I thought it only right I have the build diary on here. The car in question belongs to my better half Amanda who has owned it for the last 9 years. It’s a 1.6 8v Astra mk3 Arctic, with the Arctic meaning it has aircon as standard. The bodywork needs a little tidy up here and there but it is solid with no rust. It’s got just over 50K on the clock and it’s been dry stored for the last two years. It has always felt so under powered so the idea of a 3.0 V6 conversion popped into my head some years ago and now things have started to happen. I have all parts needed for the conversion so there is no excuse with only time being my limiting factor.

    How the Astra looks currently. When the body work gets tidied I have some brand new Irmscher side skirts and Irmscher rear top boot spoiler to go on.



    Decided today was the day and I took the plunge and removed the puny 1.6 8v.





    The donor 3.0 is a late spec ex-police Omega saloon but I still need to rip the heart of the beast out, might start tomorrow on that if I can be bothered. We have had the Omega since last September but I’ve just not had the time to start removing the lump. The 1.6 is now on the Omega back seat so there is more weight come the time it gets weighed in at the scrappers.



    A few extras I’ve got for the project
    BTB stainless down pipes with 2” primaries leading into 2.5” main system.


    F28 mechanical drive with ATB, currently getting checked over with my gearbox man. I've also had this blasted as the paint on it looked terrible.

    a m8 of mine is wanting his F28 gearbox checking over, any chance of some details on the chap who's looking at your F28?
    the gearbox people i know dont want to touch it up here.

    keep up the good work Harv looks like a nice project, i bet your other half will be chuffed when its finished.

        There's a place Bazw used for his F28 in Doncaster, might be a bit closer for you, drop him a PM as I don't know what they are called. As your a club member there are some exploded F28 diagrams I placed here so it might be worth taking these when asking about an F28 overhaul. My gearbox man is good but takes forever as he works alone and is always busy.

              I've seen a few sets of Mim Raffions pop up on MIG and other forums so keep your eyes peeled as you might get lucky. I purchased the wheels brand new in '98 from Wheelbase in Oldham and they were on my old mk2 before Amanda swiped them for her mk3.

              My old mk2 with the Raffions fitted, I'll never forget you R.I.P.

                    Well I think I've just managed to sell the Omega donor shed, less engine, so I need to try and get it out this coming weekend.

                    Appreciate the comments about my old mk2, it certainly went through a change in the 6 years I owned it.

                      Thanks to MPH (Matt) I now have a 20mm front ARB from a late spec GSi. That should help improve the front end a little as the puny 16mm wouldn't of been up to the job.

                        Had a few hours on the Omega yesterday and now only have the PAS to drain and disconnect, engine oil to drain and side engine mounts to remove and then it’ll be out. You have to be a contortionist to remove the top gearbox bolts but sheer determination got me there in the end.

                        Also had a bit of a spending spree as the mk3 I found all the ball joints and wishbone bushes had seen better days so I’ve now got brand new replacements.

                          Well I’m pretty proud of myself as I got the V6 removed from the Omega yesterday and popped it in the lockup where the Astra is being dry stored, all on my own. I stripped the Omega intake and manifolds and just have the sumps to swap over and ancillaries to remove and clean up. Found one of the heads to have a snapped stud so might remove both to check them over and get the stud sorted. All in all a very good days work.

                          Getting started after draining all fluids and disconnecting everything



                          Hey presto, out it comes



                          Stripped manifolds and a few other bits at the top of my drive, my neighbours think I’m mad


                          All packed in the back of the faithful Frontera ready for the lockup
