    Default Elite nav 2.8 t 4x4

    Hi guys new to the forum and looking for a little advice. I recently acquired said car from the title on a 58plate all running well with less than average miles. I have a couple of questions you guys should be able to help me with 🤞 First one is what if any are the common faults with this mk1 model. Second is am I right in thinking that to get this upto vxr speeds its a map and a turbo or am I on the totally wrong path lol. Third and I think final is just how much could I gain out of this power plant?

    Thanks in advance for any replies guys

    P.s
    Long term my plans are to make this faster than any vxr 🙏🏼😂

    not sure the elite engine has the same heads but generally your right.
    mk 1 engine... watch for timing chain stretch.
    then the rest is similar... haldex service... clutch to watch out for...avoid traffic light sprints and it should last

    It is going to be very expensive to make it faster than a VXR. Turbo, injectors, induction, exhaust, cooling, suspension, brakes - all will need upgrades to make it just VXR fast. Going beyond that point will require new clutch/flywheel and a Haldex upgrade. These are not cheap cars to tune!

    Dalle the Haldex "upgrade" from Thorney isn't actually a full upgrade. I have spoken to the company that Thorney sends them to, and they told me that the parts are all replaced like for like oem. The only uprated part is the seal, to the same spec as the Gen5 Haldex as it was this that kept failing on the Gen4.

    Also, it is an exchange differential, your diff is sent away and one that is already in stock is sent back, so it is highly unlikely you uave your original unit. And the pumps don't necessarily get replaced as I found out. After having the "upgrade" for 18 months the pump failed (which is what I originally went to Thorney for) only to find when I looked at the diff, the pump that was actually fitted was older than the one sent away. My car is 2010 and the pump now fitted was 2008.
