    Vin 11408, LS Swap

    So I decided to take the plunge this winter and effectively double my hp an torque. Now to make everything work. I will update this thread as I go, I am shooting to have a driver by spring.

    Info:
    2006 5.3L LS4
    UN1 Trans
    Trans moved forward 3"
    Originally was going to run MS3, now planning on running stock GM computer.


    Picked the engine up from the wrecker, 64000kms. Notice the compact water pump.


    Out with the 3.0!


    Adapter plate


    Initial mock up. This is where I am at, revising the transmission mounts.

    If you don't mind me asking, what does a used LS motor go for? $-wise?

    Well you can pick up a iron block 4.8 for as low as 300-400 I have heard. Aluminum blocks comand a little more money. Generally, 750-1000 for a motor and wiring harness is reasonable. All these numbers apply to the more readily available motors.

    The true ls motors (from corvettes, etc) command a higher premium. But then again it is a vette motor. I am refering to the LS1, LS6, LS2, LS3.

    My VIN:    Pending. Previously 10115 & 5252

    I just love how clean & compact LS engines look in the DeLorean engine bay. Was there a reason why you chose the LS4 in particular? I'm guessing the fact the engine was designed for transverse mounting means more compact accessories like the water pump? Will you have to swap out the oil pan, or modify the current one?

    I noticed you've removed the exhaust manifolds. I'm guessing they won't fit due to the engine cradle? I'm looking forward to what you'll come up with for the exhaust system. I'm trying really hard not to pepper you with questions... I'm such a huge fanboy of these LS swaps.

    Good luck with the heart transplant. Will be watching this thread at every update.

    BTW, where did you get the adaptor plate made up from?





    Haven't seen anyone do a swap like this with an Auto yet.

    Is this just a general comment?

    I thought Josh's UN1 tranny was the usual manual box

    Thanks for the interest! There are lots of custom parts to be used, the adapter is no exception. I drew it in CAD and had it laser cut. Same goes for the motor and transmission mounts, done on the computer first and lasercut and welded together. Currently designing the flywheel.

    I chose the LS4 as it had to be an Aluminum block and readily available. Displacement didnt matter. So that only left the L33 and LS4. I found the LS4 generally were lower milage than the L33 and due to the different bell housing pattern, lest desirable to most so I picked it up for a decent price. Physical benefits would be the compact water pump (4" shallower than a generic LS waterpump) and the displacement on demand. Im thinking I can hit 30mpg crusing on the highway in 4 cyl mode

    Haven't gotten around to exhaust yet, that will be tackled next year. But clearance shouldnt be a problem. I am currently planning to use some c5 manifolds directly to some high flow mufflers and that's about it. The routing would be similar to Hervey's exhaust setup.

    It worked out to be much cheaper than a MS3x and with HPtuners all the same functionality (as far as I am utilising it). The tune is already very well established so its a great base.
    Keeping the GM computer will allow me to retain knock sensing, displacement on demand, and drive by wire (computer has built in cruise control too!). Things that are not possible with MS (well at least not easily possible).

    Yep, my car is a 5spd. 300+ crank HP would destroy an delorean auto box.
