I want to know what happens if you put forged internals in a N52 and boost it to 800hp :)
I might transfer my internals to a M54 block and head I have laying around in my garage..

But the N52 is interesting, too bad no one put a lot of power in it yet.
There's also a supercharger but it's quite expensive and has some limitations (no intercooler, not enough fuel, limited boost, etc). If you want boost, the N52 doesn't really make sense to me.

if it seems like a cruiser, consider how long the gear ratios in modern BMWs have become, due to strict emissions and fuel economy requirements. I know lots of guys here wish they had a 2.0 final drive ratio and a 3 speed transmission, an being able to go 75mph in 2nd gear is nice, but it really hamstrings the engine. Especially in a modern 2 ton pig of a car that they have all been shoehorned into.
you cannot even bore it the cylinder are AluSil bores, why would you want to stress a such a unrepairable block? at 6k a piston in a gasoline engine is subjected to nearly 10 tons of force every 0.02 second as repeated explosions heat the metal to more than 600 degrees..
I like to see how these light weight reduced rods hold repeated abuse of a 8k rpm..
..Valve tronic technology varies the valve lift rather than throttle opening thus the 7k rpm, know how to control this for you planed 7500-8krpm?
They had to use steels inlays at the bed plate or the crank would turn the entire bed plate to shit, as the magnesium bed plate would not hold up..
was their not a solution for this so called shaking to bits m54?
You can get a crank damper for the M54 and do some stuff with the oil pump, but all that might do is get you close to the *stock* N52 redline. And without something done to the cams, you're not going to make much power above the stock redline anyway.
To me, the point of an N/A motor is the responsiveness and being able to wind it out. having the effective redline of a stock M20 doesn't do it for me.
Look, I'm not arguing that the only engine worth considering is the N52 - the M54 is pretty nice too, and it's good to see people moving on from the M50. But it's pretty clear that people don't understand the differences. I'm pretty sure the N52 is lighter than the M54 by more than 20lbs as well (as I said, there's way more to it than the exhaust manifolds, the entire thing was designed from the start to be light weight).
The M54 is definitely an easier swap, since it's so similar to the m50. N52 hasn't been done by anyone, and there are hurdles like the oil pan design & flywheel to deal with. Ix swaps are difficult enough. I'm sure we will see some M54s in the ix soon enough!
I don't think the N54 is that much heavier either - and even if it is, it definitely can make more power than the S54 while being considerably lighter. I'm just not interested in Turbos. :pLast edited by nando; 10-17-2015, 07:17 AM.

Sorry if this has been answered before but what is the oil capacity of the frankpans vs stock and has anybody run any sort of secondary storage/overflow?

what is Nisse RPM set at?Last edited by King Mufasa; 10-16-2015, 12:56 PM.

N52 is lighter.. Theres way more to it than the manifold. Aluminum bolts, hollow cam, etc. And the bed plate design is much stiffer (n52 stock redline is 7,000; M54 will shake to bits at that speed). The M54 was origionally designed as an iron block (M50).
My goal is 7500-8000 rpm, ~280-300bhp and less weight than the m20.

Hhhmmm...Are those S38 little heavy, how about S14 or some 2-2.5 litre 4-cylinder Bmw engine, they are light
