    Vehicle : Vauxhall

    Trim : very

    Engine : Z19DTH

    Year : Nosey

    Default No more!

    I've spent too much time and money, ignored my lovely and gotten very stressed at points, all just to get ready for this weekend.

    NO MORE!

    That's it, I've finished now and what is sitting out there now is what will be there this weekend.

    Well maybe just another tweek of the filters.

    Anyway, here's a little list of what mods I'll be sporting for the rolling road on Saturday...

    1) rear scilencer removed
    2) turbo down pipe de-restricted (pre-cat removed)
    3) custom airbox with two cold air feeds, sporting TWO foam air filters
    4) twin intercoolers in series (standard one and the biggest FMIC that would fit, infact it doesn't fit properly it's so big)
    5) Tuning box obviously
    6) Turbo overboost spiker, running upto 32PSI (That's what I'm calling my one way restrictor )
    7) de-restricted upper front grill with extra air feed slot
    8) and finally, some insulative lagging of air pipes

    So as I said to spoons yeasterday, "it's on like Donkey Kong!". I wasn't sure I was going to have a car to drive at all at one point yeasterday but I went to plan 'B', cut some bits up, got them welded today and it's all good again!

    One problem though, I did notice a touch of clutch slip earlier... Might have to tune it down a fraction for the rollers to be sure of avoiding this.

    I was going to ask if anyone had done this. Have/are you going to do the manifold also? Nice little touch by the way.

    Don't diesels need the back pressure from the exhaust for the torque like a petrol?
    Now I need a turbo to keep up!

    Cheers, should do the job nicely.... It also makes the exhaust note a bit more muffled.... in a sort of 'burbling' sort of way....

    I'll do the manifold another day... when I replace the heat guard !!

    Back pressure is very important as it provides torque !!

    So what is the gain for nutron removing the exhaust from the turbo downpipe apart from loosing torque?
    Now I need a turbo to keep up!
