    2.4turbo or 2.5mtdi or 2.5tdi swap

    Hi fellas. Great forum.
    My bro just got himself a reimo t4 in good nick.
    Itís a 94 or a 95. Not sure off top of my head.
    Anyway itís a 2.4d.
    Not huge mileage and pretty well serviced.

    Thing is. He recently picked up a 2.5tdi (102bhp) donor van for small change. Actually saved it from the crusher.

    So we were thinking of

    A. robbing the 2.5tdi turbo and intercooler bits and pieces and bolting them onto the 2.4 lump.

    B. putting the 2.5 lump in and making itís pump to run mtdi. Or indeed modifying the 2.4 pump to suit the 2.5 lump.

    C. converting the whole thing to accept the full 2.5tdi with ECU with throttle and immob. the works. Whole engine loom transplant etc.



    If you guys had the choice. Which of the above options would you go for. ?

    Bear in mind, weíll do it ourselves but we are not awfully keen on electrics and Iím especially not keen on the vw tdi reliance on n75 valves and mafís and map sensors and throttle pots. etc.

    Gear box wise, Iíd need adivice as to which would be better to add a more mpg friendly 5th gear to. The 2.5 gearbox or the .í2.4.

    Thanks in advance.
    Dan.

    Well, good luck. You're asking in the right place though, so you have that on your side.

    I'd go for" turboing" the 2.4 but I seem to be allergic to ECU's.

    The better solution is surely to sell the vans and parts on this forum - cheaply - & buy a T5? Better still give them away knowing your souls will be forever cleansed? Eh, what.... just thought it was worth a try... There's lost souls out there guys!

    If it was me, I'd swap the lot - no brainer really.

    Did you have lego as a kid - its much the same.

    There's actually less work involved in the full swap .

    Unbolt, take pictures, lots of pictures, get a load of freezer bags, label assemblies as you go.

    label the loom as you remove it, the fusebox end is all colour coded, so easy

    Just swap all the bits over, at least you have all the bits.

    The turbo'ed 2.4 will be underpowered and fragile

    The mtdi will always be a compromise and you cannot make the TDI pump into an mtdi one - you can make the ID pump into a mtdi one, or even better hybrid the two.

    But the TDI will ultimately be the better van and will be more saleable should the time come

    Option C all the way. They're so simple there's really no reason not to just swap the whole lot in. Mtdi is just a bodge when you've got a complete donor available

    What do you mean by fragile reg? Iíve heard they are bullet proof but I have held off doing it as I am worried it could cause problems

    Right, I'm going to offer a more serious answer...

    My plan would be to end up with the ACV 102bhp AND the gear box, hubs, brakes as much as I could transfer over but the engine in an upgraded form.
    Upgraded turbo, manifolds, IC, injectors, DP, as its quicker to fit out of the van.
    Break the rest of the ACV van for spares and sell on this forum.

    But first upgrade and document the 2.4d with the surplus ACV parts, turbo, manifold, IC, manual boost controller (8-10psi), get it running, video then sell this engine and gearbox.

    Decisions, decisions, - Best of luck!
