  • Supercharged V6 GTE

    -----------

    The Plan Revised;
    A GTE powered by a 3.0l 24v supercharged V6, through a 6 speed F28. Initally through the front wheels, using the M-Tech converter, then, when time, money and, more importantly, space allows, convert the car to run 4WD using the transfer box (modified using a brace for the engine facing side and a oil cooler and electric pump) and 4WD setup from a calibra.

    -----------



    Well folks I thought, time to post on the progress so far... I now have lots of pics of the stripdown, but first a little background as to why...

    After owning my first 2.0l 8v GTE I decided I wanted to do something with it but was unsure what. The LET conversion was considered and discarded, because it seemed everyone had, or knew someone who had, gone down this route, so I then considered N/A power and on a whim bought a 2.5l 24v V6 (the C25XE).

    In hindsight, I should have held out and bought a 3.0l V6 knowing what I know now, but anyway...

    ...3 years pass, zoom to now...

    ...The Rebuild as it happens...

    The original inlet manifold was lost long ago, having been removed for polishing, a new one has been bought but may not be used now due to the current supercharger plans, hence it never appears in the pictures...



    Stripped off the fuel lines, the next part of the manifold, the "bridge" + sensors and the other parts from the gearbox side...



    It's at this point I notice something looks a little odd in the cylinder heads...



    As it turns out the engine has a little rust in some awkward places, but as one of the parts I want to upgrade is the valves on with the stripdown...

    Remove the cover...

    et viola..

    Now all the pullies, belts and the backplate have been removed...



    How much engine can you fit in a box?



    This much!, and the stuff I added today.

    Now most of the external components have been removed I had a crack at the cylinder heads, removing the inlet and exhaust cams and then complete removal.





    If you look you can see the oily-watery goo in the sparkplugs, DO NOT LEAVE AN ENGINE TO THE ELEMENTS FOR 3 YEARS! They do not like it!

    Also drained the oil... I wish I'd had the video on for this, it was disgusting! first about a litre of water poured out (managed to get my had out quick but the sump nut is lost to the tar bucket!), then the muck that you get when oil and water mix slopped out followed by the blackest, nastiest oil I have ever seen! See the pic below...



    Yuck!
    Once the cylinder heads had been removed the full extend of the water damage became apparent...





    Other bank looks better...



    Well that's as far as I've got... roll on next weekend.

      oh yeah the wheelchair/engine stand... perfect when you need to move the engine around but I'm not looking forward to flipping the lump over to finish stripping

        Yowch, aren't those bores too rusty to be usable, or are you having them re-honed?

          Definate re-hone, unless someone wants to donate a 3 litre bottom end

            LOL

            I heard of a pair of 3 litre heads for sale in Lincolnshire for £100 if any use?

                Re: Supercharged V6 GTE

                well after seeing the state of that piston I've decided to scrap the 2.5 v6 idea...




















                ...I'm getting a 3.0 v6 instead!!!
                Reasons for this change of heart;
                1) the state of that cylinder...
                2) forged pistons and other bits are easier to get for the 3.0...
                3) the price I'm paying for the engine!

                Oh and ladies and gents he has another omega to get rid of, complete, about £600 and it can be delivered I'm told for about a ton. Mikeyh on Vauxhall Owners Network (sorry to the moderator for the crass plug ) someone buy it!

                  Hey, we're all friends.

                  I'm 'Ian' on there BTW.

                  Keep us posted as you do more work.

                    since all the engineering will be bespoke and made to fit yuor car, why not go for a 4x4 system that is strong and works better? theres absolutely no reason to use the flawed cavalier system *just* because you have a vauxhall engine.

                      strip an EVO for it's running gear.

                      no need to turn the engine round then.

                        tbh I had no idea that I could use mitzy running gear... when you say flawed cav running gear are you perhaps refering to the paper transfer box or is there other parts that are reputably bad?

                          Transfer box is the main weak point of the Cavalier 4x4 system.

                            I found a company who can do a complete rebuilt transferbox for £1500 with all new uprated internal
