Another N52 Boost Thread
I know this is something that's been discussed at length in various forums, but, here we go again...
Most people say it can't be done. Some people say it's because the motor itself is made from such lightweight materials that it can't withstand high (or even ANY) boost. Other people say it's because the N52 has Valvetronic and they couldn't get it to work properly with forced induction. Now, excuse my ignorance, but I believe the current M5 has an engine that has Valvetronic and uses twin turbo charging - the S63TU I believe is the engine code. Surely Valvetronic wouldn't be the culprit in trying to boost an N52, any thoughts? |

Correct me if Im wrong but I know BMW uses magnesium blocks now, and typically the N52 motor as a result is borderline at its limit from factory. Now I know the pistons & rods aren't forged and coated and with its compression I couldn't recommend boost

Supercharging theoretically seems to be a great start, even step. As the revs climb, so does the power, and it wouldn't nuke itself in torque. Yet no one really knows how well the N52 hold's up under boost except for the tuner's who've tried (I'm looking at you ARMA, MMW) and they have all but scrapped their projects for *probably* reliability issues. I'm convinced its just a hot mess, and even if they eventually build a supercharger kit, I'm leaving mine N/A. What people SHOULD be talking about: S54, S65, or LSx swaps |

Armaspeed actually updated their design to use a rotorex supercharcger. One should consider them if they live in a country that taxes luxury cars.
Otherwise one should be happy with a 125i/128i with headers + tune, and 3 stage disa for 128i. Even without headers I'm satisfied

Just seems a bit silly to get a 128i and then want boost. Wrong car.
S65 swap is becoming more and more common, I know of at least 5-6 now. I think my eventual ideal will be a blown engine 1M that I can swap to a S65.

You'll only need to wait a few more years until those come rolling in (pushed in), but I already think it's a mighty fine idea for the 128i. Every once and awhile I'll check that Egyptian 120d -> 1M S65, and just think of the possibilites. I don't even think he needed to go full 1M except for fitting more rubber underneath. Dreams really make reality suck sometimes lol.

I know of 6 E82/7s that have been swapped to a S65 at this point. Quote:

^^ You'd swap the engine, transmission, drivetrain, and probably differential too. Remember, we're a 3 series underneath. I obviously don't know the logistics, but I'd imagine a lot would bolt up without too much fabrication, short of a cut driveshaft and new engine mounts.
^True it's heavier than our engine but our's is long and high up. The S65 would presumably sit lower in and sunk back. This could affect the weight balance but I could almost guarantee the car wouldn't sit more than 52% front. Either way, throw a roll cage in the back and fuel cell in the trunk . |

S65 makes the car more mid engined, and presumably would get closer to fixing the balance of the 1M. Remember, not talking about a 128i here. After that you just need to toss the stupid 19"s and you have a pretty solid car.

Yea I didn't read clearly, I was referring to the 128i
Also I meant to respond to the two people above you. If you look at the time, I took a while searching for weight and balance numbers in advanced reply and you sniped my post haha. |
