Motor change to a BMW E30

Greetings to all, mechanical partners. My consultation is related to a project idea that has been around my mind for some time. I had thought about getting (from here to time) with a BMW E30, and I will prepare it to my liking. But the main doubts I have are related to the engine. I would like to take away the M20 you carry and put an M54 or an N52. (With more horses, and not so shot). I know there will be some conservative that would want to kill me, but the idea attracts me a lot. Logically, the gearbox would also change, but apart from this, do anyone know if there is a lot of fuck when placing the motor supports, that is, welded a lot? And another question, do you think of how to address the engine of the engine? Obviously, the M54 or the N52 would carry its corresponding UCE, but I skip sparks on how to make that "transplant" in the E30. Let's see if someone has had any experience of this type, and you can recommend something. Even some book about UCE's or reprogramming, I don't know, the truth is that in this field I miss a little. Any contribution will be welcome. Thank you very much in advance, and happy year to all !!

Look in the EMOS workshop made several motor changes, many have even before me my real uncle arrived almost 140 changes since the engines beat the groups by oil companies, well I have made transplants of new engines, you change ECU, you change the box box, now there are many details that you must buy it with the wiring, that is to say the cable branch, the supports is not so terrible, you should not be attentive. The AGAS do not hinder you to get components such as oil filter starter etc. Now on the occasion the vehicle has a front traction and the engine to be installed is tracera and there to get pallieres masses and a lot of things if they have the same traction, there is no problem, if the cocker collides can be cut and turn around, there are artos details but you have to see it, anyway if your calculations are well made I tell you that I like the people who do this type of projects are very entertaining. Hahaha but you can luck and compete for anything to give it in front of your project, it will be a only vehicle.
And as a conservative if you want to kill you but that you are going to do hahaha is not a joke give it no more. Imagine that we took out an engine from a Chevrolet Montecarlo and put a 6 online oil from Nissan Jajajjj that if it is to kill a classic.

Wow, thank you very much for the info !! Asking for the UCE with the wiring included was a detail that had not taken into account. Otherwise I don't think I give me too many problems. The original engine is 6 online, longitudinal and rear traction. The one I want to put is the same, only with more horses, and more modern. (I think it is the engine that mounts the BMW E36 or the E46). I am very good for all this information, because it is what you are going to make this project to start. Thanks again.

If they are both with traceras traction, it is even more potatoes, you will have no problem in the worst of the boxes adapt the cardan but that is easy there is no problem. give him in front and luck
