    Garrett gt1749 VNTs

    I have some,I got them for modding Dini engines but have learned that its the GT turbo boys that make better use of them

    If this is so can I be pointed in the right direction?

    They're far too small, too much work in modifying them to fit aswell.

    They're a 120hp (at a push) rated blower. Waste of time going through the aggro of getting one to fit.

    Don't they get fecked quite quickly by heat as well? Not what you'd want on a GT engine

    that 1100hp alfa looks fun...

    I'm guessing that some of those cars use 2 turbos

    Re: Garrett gt1749 VNTs

    I think we'd need to know the sizes of the wheels in that turbo, from what I can see there are 13 possible compressor wheels, and 3 possible turbines. Some are smaller than the standard 5 turbo, and some are a bit bigger.

    Std GTT T2 turbo

    compressor 48mm exducer, 33.95mm inducer, 50 trim
    Turbine 47mm inducer, 35.25mm exducer, 56 trim

    You can pretty much tell compressor flow by the inducer diameter, ie 33.95mm

    For the GT1749V

    compressor 49mm exducer, inducer between 32.9mm and 38mm
    turbine 43mm inducer, 35.5 to 36.6 exducer

    To put that in context, a T25 with a 60 trim compressor will have a 42mm inducer.

    more info needed...

    You're having a laugh, the 3.0l use the GT22. Give me the part number and i'll know exactly what unit it is.

    Get a GT2559 off the Espace/Velsatis.

    60mm compressor wheel, T3 sized cover, 54mm turbine wheel.

    Bearing housing shot would have helped jog my memory. They've got a Toyota style core, oil feed from the bottom (which is a twin feed pipe, hard to explain) and a drain right next to it. A massive pain in the arse...

    Well if you can get the adaptor from a car that used it, no hardship having two braided hoses connected to it for your drain and feed.

    I guess not, you've got to find the adapter to start with. I've chucked quite a few away aswell

    Apart from that, you need to precisely drill new positioning holes for the vnt, modify the manifold, modify the water lines, modify the elbow, and find a blanking plate for the ecu plug on the top of the actuator. They also run about 18psi stock.

    Re: Garrett gt1749 VNTs

    I just remembered, the actuator would sit practicaly on the manifold with that turbo, impossible to rectify, so not suitable.

    True, but you would have hell of a spec standard VNT.

    Its basically a T28 spec turbo innit, with VNT. Even the ex housing fully opened is 0.64 AR IIRC..

    Could you not lengthen the rod and remote bracket it up so the case of the actuator clears it?

    It's hella big, I'd opt for a different bearing housing though, just to have the actuator in a safer position.

    Yes, but how far above the manifold do you want the actuator to sit? Heat rises

    Wrap it.

    Or if poss use a twin port actuator, flip it 180 and use it as a puller instead of a pusher.

    There's a wall on the bearing housing, i'm not sure if the actuator arm would clear it. Does the wrap not absorb the heat too?

    If you are unable to view it,it maybe this new ebay system that prevents you from looking at foreighn listings.Im in France and so is the listing which is why I can look at it.Its a stupid rule,the seller now has to pay a fee to become visible to overseas bidders.
