    Really? They are using a direct acting cam? Seems like quite a departure from the older/non-world engines, but is simpler, but taller from a packaging standpoint...

    I would have looked into the World 2.4L swap by now but I'm up to my eyeballs in TIII stuff right now. I wish I would have taken a picture of the cylinder head and valvetrain on my Caliber when I had the valve cover off. There aren't any rocker arms or lifters; just cams, buckets, and shims as far as I could tell. Oh, and the cam phasers Those are neat.

    Sounds like a winner to me! At least as far as the head goes... I wonder if it would retro-fit to an older 2.4 (and therefore the 2.2/2.5)... Of course if there aren't any Achilles's heels in the world engine, it would be a smarter bet to just do a swap...

    From what I remember about the "world" engine the bore spacing is entirely different. The thing *I* don't like about it is that it is semi-open deck! It doesn't seem to be an issue with the Evo guys, but still...I REALLY don't like that design for high power numbers. Ask the Honda guys about how well that arrangement works. :/

    There are no shims. The buckets are individually selected by thickness.

    There are other neat features. There are two theromstats, one for the cylinder head and one for the block. The water pump is virtually a belt driven remote style. The oil pump is chain driven and located in the pan. I don't like the fact the 2.0/2.4 integrate the oil pump into the balance shaft carrier, but that is easily fixed by installing a 1.8 oil pump that does not use balance shafts.

    Engine swaps would be very involved. The plastic intake is fly-by-wire throttle body. The Caliber transmission would require being used or an adapter plate made. If you use the transmission, axles would have to be made. The PCM requires 3 other computers be working properly to let it function correctly. It's not that it can't be done; it's just more work than most are willing to do. Personally, I'd love to SEE it done.

    Re: TIII billet aluminum mechanical rockers being tested.

    Very cool. Would love to scoop up one of those drivetrains someday but waaaaay too many irons in the fire already. I was thinking if I did it I would probably not even try to run factory '08-'09 electronics and go aftermarket. Heck maybe even a cam driven distributor could be made to work with minimal fab but that seems a little archaic although it could minimize the hassle of adapting to the older car. I would most definitely get away from the stock intake manifold. I hear it has some kind of solenoid operated ramps to promote air flow at lower RPM or something. I had wanted to powdercoat the intake as well until finding out how much was really going on in there and that some the components probably wouldn't hold up to the curing heat. The valve cover seems to be made of same material and withstood 375'F for 1/2 hour without a problem.

    dual path intake to give you more torque at lower engine speeds and power up top.

    Re: TIII billet aluminum mechanical rockers being tested.

    Id run it off of a megasquirt. generic cam and crank sensor wheels can be used to retain full sequential injection and ignition and probably drive the stock coils though LS1 wouldnt be a bad choice here.

    someone could datalog the stock ramp intake flap thingies to see when they open and then duplicate it with various means, rpm window switches, wastegate actuators (make it boost activated) or other things.

    mechanically mounting the engine and connecting it to a trans would be the most difficult thing in my opinion but i love engine management and electronics though.

    oh wait, there is variable cam timing on this thing right?

    some datalogging would be needed on the wiring that controls the cam phasers to determine how they are controlled and then that can be duplicated as well.

    Re: TIII billet aluminum mechanical rockers being tested.

    To bring this thread back from the dead a bit --- I too have had a T3 motor where a roller pin had failed and grenaded the top end. How about a simple fix for this, maybe some clips that slide over the rocker and retain the pin, similar to what chrysler was installing on the diff pins in the later differentials... just to try to keep the pin in place a little better?

    So apparently, these 10k-rpm mechanical TIII rockers never materialized to production/group buy? Long term testing didn't pan out?

    Re: TIII billet aluminum mechanical rockers being tested.

    if I had to guess, i would guess it has been about 5 years or so last time I spoke with Wallace over the phone and wasn't doing much car wise with personal life things going on. I haven't seen or heard from him in ages so i'd guess maybe car stuff is not part of his life at the moment? it would've been nice to have a different avenue of obtaining parts or upgrading parts prone to failure being as old as they are and under such stress.

    We have a few NOS sets left of the TIII rockers and lifters.
