    Known LSx swap combinations. Please Read.

    OK everyone, I want to start a list of cars that have LSx engines in them right now either in completed mockup or driving down the road. I want this to be a guide for people to look at and see if they find their particular car and what parts it took to get the engine and everything physically in the car or truck really. NO guessing or speculating which is why I say completed mockup or driving down the road. I really just want to see the list include whose motor mount plates were used. What headers/manifolds you have(include application if it's different than your actual car). Are you running a stock frame. What accessories brackets were used. I want this to be simple, short, and easy to read, so ,please, no paragraphs. Also, include any extra work that was needed such as notching the frame for those of you that have the AC in the factory location. If you have a corporate powered car please say if you switched to SBC mounts from the BOP mounts or not.

    Please, do not ask questions about your application if it is not in the thread. I will start another for those that do not have headers available or motor plates availible for their particular application. My hope is that the holes will get filled and at the same time a list of what works will get started.

    I do not have my own to add just yet. For the time how about this example.

    Motor mount plates:
    Oil Pan:
    Accessories Brackets:
    Misc: give a short explaination here about possibly notching the frame or heater box. Anything that you feel needs to be known about the combination you chose including aftermarket chassis/subframe.

    If you feel something else should be added or if you simply think you can do this in a more organized manner, please speak up or simply do it in your reply and hope it starts a new trend. I'd just like to see a list of known combinations started and for it to be accurate and precise. I think it would really help a lot of people out.


    EDIT:Thought about this today while commuting and thought I would add it as well. Those of you using truck motors, please mention if you used the truck intake or not and if it fit under the factory hood. Thanks

    They're pretty much the same, 59-64 X-frames,minor differences between plants but all pretty close. I've done two swaps in this car, LS-1 / LS-6 w4L60E and now LS-7 w t-56. The LS-6 I put 9000 mi on it pulling it for another project after wanting a stick to hook up in the twistys with. #1 LS-6 w F-body oil pan and accessories,had hi mount AC brackets from Mcgee's in WA,Street & Performance mounts and Hot Rod headers,(that turn downward, not back) to clear the X-frame, used borgeson joint at the 605 box,(rag joint won't clear alt.),Bow Tie Overdrives cross member for the 4L60E, (Hesparia,CA),S&P harness ,PCM, fuel pump, filter, and regulator, Griffin radiator (stock appearing but made up for LS hoses and steam line). No clearance issues at all. #2 LS 7 dry sump pan is actually 1/2" deeper at the front, I had to heat and knock the pass side of K member down about 1/4" to clear pan, used stock LS 7 accy except the AC,(left off for the time being,but will go back on with a modified McGee set up,higher idler to clear w/pump outlet) Cut the mounting plate off the Bow Tie Overdrives crossmember and made a new plate to the backside and lower, Street & Performance engine mounts, headers(re-cut collector flanges to aim downward to get under X-frame),S&P supplied harness,PCM,fuel reg,fuel line @engine, If you can think of anything else let me know........

    Got thrown out of the BMW community when I started this 4 years ago but now there is even a website that is for engine conversions to BMWs.

    The complete LS6/T56 drive train weighs 140 lbs less then the 24 valve 6 cylinder and 5 speed I took out.

    Getting anxious to finish.

    '55 F100 with a second gen Camaro front clip.
    2002 LQ4 moved back to clear the stock deep pan, conversion plates and standard chevy mounts on some home made towers. Firewall got recessed too but thats due to setting it back I think. Is going to be twin turbo so no headers etc yet.

    1979 Malibu Landau Classic

    Vehicle: 1979 Malibu Landau Classic
    Motor mount plates:BRP
    Headers/manifolds: Pacesetters for an 02 fbird (modified on passenger side)
    Oil Pan: Stock 2002
    Accessories Brackets: Stock 2002
    Misc: Notched frame for AC and for Pan TIG welded patches in place. Would not recommend the BRP mounts or tranny crossmember. I ended up having to replace the tranny crossmember for dual exaust after I modified the frame to accept it (about two inches to short frame to frame). Jeggs sells a better one that fits stock mount location and that allows for dual exaust for a quarter of the price BRP wants. The engine mounts were way off when you put them together there is about a half inch gap that allowed the engine to move left and right. This is not wise since the heater box is soo close to the ps coils. I fixed this by adding washers in the mount bolts (over $500 for the combo and no call back from BRP after five tries). Realistically you can get the combo that works for 250-300. Had the CPU done by Wait4Me and did the relay work myself. I would suggest going with a company that includes relays or go with a painless setup, relative to $$$ availability and wiring skill. I am more than willing to help any other g-body swapper and help you avoid some of the $$ traps and pass on the lessons learned just send me a message.
