    My 3:18 is for sale

    I'm confident in my new 3:18 rear that I put disc brakes on, so I am now prepared to part with my other 3:18 rear axle that used to be on the Red Baron. See the Ad Board and thread. Bidding starts at $250 and will run for one month.

    GoinManta - the new OGTS from the East? A birdie in my ear tells me it'll be a deadborn child, but Kudos to Charles if he pulls it off!

    The 2.4 exhaust manifold is a little bit different to the earlier ones.

    It has the twin outlet pipes at 90 degrees to the usual manifolds
    It flows better than any other standard one,
    It has the drilled tapped hole for the lambda sensor.
    The lambda sensor maybe needed with the FI 2.4 set up, it comes with one as standard.

    The standard inlet manifold is too long for a GT although may fit the Manta.

    Perhaps he has some 6 cylinder 3 litre manifolds for sale that can be modified to suit

    Not all 3 litre inlet manifolds are the same though some research will be necessary.

    Here is my modified 3 litre one with a slightly modded 2.4 TPS.

    Lest we forget, I have a stock 2.4 manifold on my GTX's engine with a custom made-for-a-GT 2.25" headpipe by RallyBob. He also made a 2.5" one for someone with a performance 2.4, I think. So, he may be able to make a headpipe for those with a GT who want to keep the VERY quiet and good performing stock manifold

    BUt yes I am sure if he has any I can get one or two.. just have to get price. They maybe scarred and the seconds. But I think you maybe able to do something with them.
    If I had to guess.
    De-stroke the 2.4L crank in order to use long... connecting rods.

    It is. It's about an hour of math and other calculations to figure all the dimensional work.

    Then, ship the crank to a guy who lightens it, grinds the mains, grinds the thrust, offset grinds the rods, and balances it. That's just money on my end.

    Order the rods I chose to do what I need them to do. Again, just money.

    Using my previous calculations, design and order the pistons. More money.

    Have the block machined to the piston size. Grind for rod throw clearance too.

    Assemble.

    It's all about the first step, figuring it out. And paying for it.

    Yea.. for YOU the figuring it out is simple.. For us mere mortals, its way above our paygrade.

    One of the things with offsetting the crankshaft is that it could go both ways.
    Offset one way increase of stroke
    Offset the other way decrease.

    Then please look at the rod journal size
    it will be in most cases smaller.....
    Smaller Rd Bgrs =lower BGR speed

    Frontera Grille

    Hey Charles,
    If you go with this, I'd be interested in a Frontera B front grille for my 2002.
    Cheers, Rob.

    Right now we are down to a few things I want and what kwschumms' 2.4L

    Two Kadett Fenders, and maybe some misc stuff.

    I few others backed out for unforeseen circumstances.. :'(

    So we maybe down to one small crate, and I will have to reevaluate how much that will cost if its half what the quote for two was then all is good. If its not, and we are back to high shipping prices, then hard to say.

    I was thinking of getting a Frontera and bringing it over.. and that's still not completely off the table especially if we still have a few things to ship.

    It is 1.7m long part Our crate with engines is 120x80 or 120x100, it must GoinManta confirm. Then we have 1.44m or 1,56m on diagonal inside. So Yours grill is too big or our crate is to little

    If we get enough order we can get the crate to 240x100.. and then it may fit.

    Maybe we cut it in half behind the logo. How much of the grill do you think you could reuse off the Isuzu ?

    I'd like a grille as too, for a '99, and the spare tire cover if it says Opel or Frontera on it as well. I would be interested in the motor mounts and bracketry needed for the engine to fit into the frontera chassis, just in case I want to put an Opel engine into my Amigo.

    Any chance on getting a CIH diesel?
    Lots of Opels, for a long time.

    With Rav if he doesn't have it, but can be found or its sold on the eBay Marketplace ( think Craigslist Germany ) he can get it..

    Right now we have a lot of space.

    I think the key for bringing over Frontera Grilles would be exactly what part is different. If we can scavenge just part of the grille and the rest can be reuse off the Isuzu, then it would be easy. A whole front grille of front clip won't be. Not if there is a discreet place to cut it so it can be reassembles that would be good too.
