2003 bmw 530i e39, 1996 bmw 318i e36
So I have a 2003 bmw 530i sedan with the m54b30/ zfg5hp19 5 speed auto with manual and sporrt modes. So I finally got my car running again, next is hot-smog/registration, then I have to buy the oem pretuned ms43 ecu from seemslegitgarage.com so my car will run like its supposed too, then after all that I want to install an lsd and and change all my control arms and tie rods with the new oem ones I have but I put polyurethane bushings on them all and have some I want to put in the rear end subframe since I'm already going rto be removing all that anyways. So my question is what options are there really for my automatic transmission i6 e39. I only found one online that says it fits my car specifically, but I'm just wondering if anyone else knows any other options that will be under 1500$ for the whole project? Also if I went With the team M-ffactory helical LSD that's on the turner website, what else would I need to buy to complete the whole project if anything at all? Once I'm done with all that the only thing I need to do is buy coilovers, install them and my project is finally all done...... until I have a reason to tear the engine open and install these 11.1cr 84mm forged pistons/rings/pins I bought a while ago, and finish building the extra cylinder head I have been piecing together very slowly. But I'm not doing all of that untill I blow the head or brake something inside my current engine. So it's done for now after ecu, Lsd, suspension refresh, and coilovers. I just need your guys help choosing the best lsd options I have in my 1500$ budget?
