Our swap mounts are suitable for all generations of LS engines. All ls engines are externally the same and share the same mount bosses and dimension. The only non compatible version would be an uncommon FWD version like and LS4 as they have a different bell housing.

Yes, interior fuctions are almost 100% functional. The items that will not work (depending on the ecu setup) are cruse control, DSC, and accurate ac temperature mixing due to using a clutched ac compressor. Heat, AC, fan control, defrost will all function with correct configuration of ac compressor.

Convertible tops have been reported to work after the swap as well.

OBDII readiness will not be functional. You can code the chassis with BMW tools as you would normally after the swap. Without any coding you will have a brake and traction control light using the Lse9x can box and Holley ecu.

An xdrive car you have two options.  We offer mounts that work with the xdrive front subframe and you will remove the front diff and axles from the car, disassemble the front axle and keep the front stubs in the knuckles to hold them together.  The xdrive subframe has limited exhaust clearance, poor suspension and steering.  The other option is to swap to a rwd front subframe, this will be the entire subframe and suspension from the struts down, and the steering rack.  These parts can be had for a few hundred dollars from a parted out BMW or junkyard.  This is the better option as you get the additional exhaust clearance and better RWD suspension and steering.  

When swapping to a RWD subframe you will still need to use an x drive specific transmission crossmember since the chassis is still x drive and tunnel is a different shape.

Can I use my 335i manual transmission?
Yes, the GS6-53BZ transmission from a rear-wheel-drive 335i can be used for the this swap.

1. Can I use a 328i 6-speed transmission?
   Probably, but it's more trouble than it's worth. Stick with the GS6-53BZ for a smoother and more straightforward setup.
2. What driveshaft do I use?
   Use an automatic 335i driveshaft. With the engine mounted on LSE90 mounts in the forward-most position and the PMC adapter, the transmission aligns with the automatic transmission position. This allows compatibility with the automatic driveshaft and either the automatic transmission crossmember or the LSE9X DCT crossmember with adjustment.
3. Where do I buy the adapter plate?
   The adapter plate for this setup can be purchased from Drift HQ. Look for the "LS -> N54 GS6-53BZ Adapter Kit."
4. What clutch do I need?
   PMC offers two flywheel options with the LS -> N54 adapter kit:
   

240mm flywheel designed for stock-style clutches. Pair it with a 550i or 335is clutch for standard performance.

184mm flywheel for triple-disk or twin-disk clutches, ideal for high-performance setups.
Be sure to select the flywheel that matches your specific clutch requirements.

The factory brake booster can easily be plumbed to the brake booster fitting on the back of an LS intake manifold and functions find after the swap.

This question will depend drastically on your build choice and components used. Please referrer to our cost breakdown video.

Currently we do not offer a GM ecu can box compatible with a GM ECU. This is in the works for the E38 ecu.
