I'll list all the parts here soon, but I had a question do I need to remove or move or replace the brake booster? I've read yes no this that but not sure. Same with the steering shaft. Let me know if I'm missing something.

    Are you still working on the swap, or is it complete? I'm doing the same in my 97 M3 sedan with a LQ4. currently researching the trans; leaning towards a nv3500 since t56's are $$$$

    also, how accurate was your parts list? I'm going to copy most of it.

    Wish you were closer to Minneapolis!

    I can offer some input as im getting close to getting my car complete....

    You can keep the stock brake booster depending on what motor mount kit you have. I have Vorshlag and it fit fine. Close fitment but still fit.

    I bought a cheap stainless set of headers off of ebay and the driver fit fine but I also flipped mine for the turbo. I used an E46 steering shaft and modified it for the E36 couplings. That and the flipped manifold could be why I didnt have an issue but each case is different.

    Im not sure about the Muscle car oil pan, I thought I read somewhere that it doesnt work with our cars, I have the stock LS1 oil pan and it fit perfect

    Take a look at http://www.ictbillet.com for the alternator relocation brackets. I used their brackets for my alt, ps and I got the manual adjustable idler tensioner. The crappy stock GM ones will throw the belts.

    Good luck its a fun process.

    Don't go with an NV3500, definitely not strong enough to hold up to an LQ4, plus it's a truck transmission.

    Thanks for the input guys... yea, everything i've read the past few days seems like the nv3500 is not the best choice.

    Do you (or anyone) have a recommendation for a manual trans?

    I havent had to time to dig deep and research everything yet. I'm looking to keep the LQ4 around the 450hp mark so I can keep as much stock m3 parts as possible for now. Doing my best to keep this as a budget build.

    Don't mean to hijack, but no sense in starting another thread.

    I'm still learning about this process and have a long way to go!!!

    Apparently a trans (cd009) from a 350z or g35 is a good alternative to the t-56 and is much cheaper.

    I've been looking for one of those.

    Yeah the muscle car pan is really tall. It's priced well as that kit.


    Must everyone uses the fbody pan.

    does anyone have the part number handy for the f body oil pan? Looking for the complete set.

    Been researching it the past few days and want to make sure i get the right part.

    does OEM fit the best? I also read Holley could fit, but dont know about the 302-1, 302-2, 302-3....


    Also, looking for flywheel suggestions.. In the end i went with the T-56 trans to pair with my LQ4

    thank you gents!
