Thread: Engine Swap - TD5 90 to .......LS1/6......?

    Engine swap

    When everyone has decided on which motor he should swap into the defender, I have a question.
    How much of the TD5 electrics have to be junked and what electrics have to be adapted to suit the new motor. I have a D2 TD5 and have had a gut full of injector looms, wheel sensors and 3 amigos.
    I would like to swap the motor for something simpler, do away with the traction control, throw the wabco abs unit away and re-route the brake lines back onto the master cylinder just like they used to be built.

    Im still seriously considering this swap too, but i am looking at keeping it manual if i can. Anyone know if theres a LT95 to LS1 adapter available? i dont know how well the lt95 will stand up to the LS1 but could be a good option till i work out the gearbox side of things as i have found a few cheap LS1s i could get very soon.

    I think the lt95 would be fine, if not i think you can buy kits to strengthen them (the army ones are the stronger versions)

    You mean the LT95 is the ONLY rover box that will cope

    Its just a chev, bolt pattern is the same, need a flywheel and engine mounts as they're different pattern

    Check out Marks 4WD and see if they have an adaptor kit for it.

    MY Mechanic looks after a 91 Classic Range, with an LS1 mated up to a either an R380 or LT77, can't remember which, probably the LT77 due to the age. He tows heaps with heavy loads, but doesn't race the car, and has seemed to stand up to that for 5 years. The conversion originally cost close to $20000

    At Least a manual is easier, i'm trying to work out how to make the Ls1 talk to the P38 Gearbox,

    Not sure if it helps but CompuShift now have a version of their ECU that controls the ZF gearbox. A lot of people using them in the UK to fit the electronic ZF onto the back of TD5s, converting from manual to auto.

    Can't remember how independent the engine and gearbox ECUs are from the rest of the ECUs in the P38.

    Right, I am sort of back on this and have been looking at LS6 derivatives as they arent all the same in terms of ancillaries and overall sizes (other differences include sumps)

    I have found a 2004 CTS-V engine with 42k miles on for a decent price (although it is plus shipping and I am still waiting a quote on that - eek!)

    I am thinking the CTS-V version is more suited than the corvette one.
    Here is the CTS: The only downside I can see to this over the Corvette one lower down is the position of the alternator. can anyone else spot any potential dramas? I wouldn't be running aircon.

    Ignore the gearbox as thats the 6spd which we have already found to be too long.






    and here it the corvette. Note the much wider stance caused by the sump and also the ancliiary positions.
