Superior bed plate?
please state where BMW states its superior to its predecessor? if its an assumption from the construction well I respect that. But facts are required. a lot of guys here including myself, "pocket change" is riding on facts.
BMW’s project manager for I-6 Andreas Welter stated when asked "if a n52 turbo possible", quote
"In the case of the magnesium-aluminum block, Welter says, “Right now, the crankcase-stress of the turbocharged engine is above the limit of the aluminum/magnesium crankcase.”
meaning N54 turbo is 340+hp stock is already over the limit of a n52. Correct BMW if they are wrong..
Although BMW refers to both engines as "cousins" their is a reason why BMW had 2 different options. N54 is not just a "its just a boosted N52"
800hp N52? I would not advise that, For a naturally aspirated greatness I do highly recommend it YES :) but should watch out for the aluminum head bolts breaking reports, I hope it was just a bad day at the plant ..
"If my M20 can tag a 7500rpm redline with used 15 year old S52 rods and a random eta crank, I don't see why a factory built, modern designed engine can't do a little more"
This is an assumption.. but why not? am all for N/A goodness :)
"There's also a supercharger but it's quite expensive and has some limitations (no intercooler, not enough fuel, limited boost, etc)."
Limited boost? of coarse and I wonder why? top Power was ~285 for $4k..
Am all for new things but first comes trial and error it return facts

Sure, you could bolt on a $250 doohickey and turn it to 7500 but it won't make any power if you leave it otherwise stock. the M54 already chokes out well before the stock N52 redline. you could build a race motor out of any engine with a lot of money.. that's not what I'm talking about. :p
curious what it put down. I bet it cost at least $20k to build though.

Yes I found these on E30.de. It's really hard to navigate since I don't really speak German. I just looked for keywords like "325ix" "ix" "M30" and "S38. Also sorry about that last pic, the oil pan pic was apparently of a Euro S50 swap. He was writing about a 325ix and a s38 in the beginning of his thread, but then I guess he switched to a S50 and I didn't pay enough attention to the pictures. Anyway here is a thread of a S38 and M30 swap.
S38:
M30:
In the S38 one it looks like he used a "oil pan adapter" to mate the two. I wonder if you could water jet a M30 bolt pattern flange or something and cut the top off of the pan of your choosing and weld the M30 and the AWD pan together. You would need custom Arms and massage the fire wall (not nearly as bad a Nisse had to though).Last edited by stonea; 10-19-2015, 10:25 PM.My Garage

Also, the 12's bolt right into E34's. I know where there's a gutted E32 750I in someone's yard, just begging for me to snatch it up and move everything in the engine compartment over to an E34 M50 525i
