Tips and tricks for anyone else pursuing the same project.
1. Intercoolers (charge air coolers) must be removed to remove alternator so that heat shielding can be removed however you can do it without draining the water. 2. You can reuse manifold exhaust header gaskets and turbo train gasket however you must spray them with copper spray first to refurbish them. Works like a dream.

Just heads up. You are also going to have to swap the oil filler neck as almost impossible to fit air intake on M5 inlets. Interference with the huge long filler neck of x6M

Installed oil filler neck from an n63 or m5. Now intakes fit proper..here is also some pics of my crankcase evac pump. That plums into my exhaust venturi the smog pump I have converted with a brushless motor with speed control. The exhaust venturi also helps create some vacuum. I chose a vortex style impeller for evac pump. When taking apart the manifold and turbos was amazing how free of oil coak my exhaust valves and intakes were. Even the inside on my downpipes were clean inside. No soot or anything. No oil in intercoolers either. Also because of the smog pump injecting some fresh air into exhaust after the downpipes. I literally have zero bad smells despite me having no catts. As the oxygen oxidises some of the unburnt fuel.

M5 Headers modification (not swap)
Hi guys,
One of the things that bother me the most about the S63 motor is the 2x4cyl soundtrack. I aim to change this as an experiment. People have thrown the earth and the moon money wise towards these things and in my personal opinion the sound only gets louder, and playing a bad song at volume 11 doesn't really make it any better. The real reason why we don't get the V8 rumble like the N63 has (and any other hot-V out there) is that some genius at BMW-M decided to extract the very last milliseconds of spool from the motor by crossflowing the exhaust banks. Cyl 1 & 4 cross over to 6 & 7 and 5-8 cross over to 2-3. This is the same for all S63s, TU and non TU, X5/6, M5/6/8/XM What I want to do is to separate the two exhaust banks. I bought a second hand X5/6M manifold but cutting that one up is a PITA because of all the heat shielding. I have acquired a set of M5 manifolds now and will be building a jig and then cutting stuff up. I will post the results later. Regarding the Turbos I have two options, get a set of M5 turbos and do that mod, or run the X5 turbos I have now, the motor only has 40k miles on it so I don't see the need to change. However this means the flanges on the M5 manifolds need to be shimmed down. SO MY QUESTION: Does anyone have detailed info on how much the M5 manifolds need to be turned down on the lathe to make the X5/6 turbos fit the flange. Remember I am not after more power, just a nicer sound. |

Bmw x5m e70 f10 turbo and manifold swap
I have been reading the forums for about 2 years to try and improve the performance at a reasonable cost for my X5M E70. Mods to start, Sprint booster, Catless downpipes, XHP gear box tune and ESS stage 2 Tune.
Finally I decided to push the button on F10 downpipes and turbos. Following the guidelines on this thread. For everyone's information. The F10 turbos do not fit into the engine compartment and they do require extensive skill to make them fit. The coolant lines, The air intakes etc do not line up. It is not plug and play. Good news however is there is a workaround to make them plug and play. Simply use the inlet housing on the original turbos and have them precision machined to fit the inlet turbine. Then they are plug and play. My car looks completely stock no engine bay change. Same inlets same coolant lines and now it has the F10 turbos and manifolds. Sadly ESS do not respond to any emails about this so I have gone with a local tuner who has given me a healthy bump up to 800 engine BHP. I can post pictures and will post actual sound and performance videos at a later stage. All in I am about USD 4,000 with all hardware and tuning. Also on another note so much has been said about the difference between the turbos. Simply the F10 turbos are bigger. See picture the original housing on the F10 turbo which has been machined to fit. This is the real reason they are better! |
