    The 6262 isn't a bad turbo. Spool isn't great, but is pretty decent for a turbo that size. I think the BW EFR series is the best out there right now. The GTX's are very nice too.

    Why not? The stock manifold should provide some pretty good flow, and it takes the guesswork out of building the manifold. Its a solid design from BMW, and mounting a new turbo in the factory position is easier. Sure its not all blinged out and a fancy tubular manifold but it does the job.

    Guess I wanted to see a badass aftermarket manifold with many different turbo options.

    I'm not saying the BMW design is bad but aren't you going to be a bit limited by trying to fit turbos to it?

    I agree with tony, A garrett gtx or fp hta series of turbo would be better suited. Spool faster and have the same top end power potential. I just wonder if the n55 motor will be as strong as the n54 motor is....If so, I forsee this as a better choice since all you have to do to run a big single is cut the manifold, weld a vband on there, create a downpipe, and tune it for proper fueling. also cheap too since n54 and n55 cars are becoming even cheaper.

    to a point...the manifold does sit pretty close to the block, but Im sure with some ingenuity you can 'tilt' the turbo away from the motor...

    As for now, I bet the stock air inlet pipe is prolly retained, and the compressor outlet pipe off the turbo to the intercooler is only some 4-5" long...easy to fabricate and replace. Sleeper status when you pop the hood!

    I am in favor of seeing a back purged 321 stainless manifold at some point though...even IF its a 'log' design..

    I'd prefer to see a log. Cheap to produce and capable of plenty of HP.

    N55 manifold sits much further away from the block then the N54's do, stock intake pipe will not fit an aftermarket turbo, compressor outlet pipe will also not work, don't ask us how we know. Its funny we were messing with this stuff such a while ago and just didn't have time to finish it. What they did is very easy to implement and should work well. I am going to just go ahead and finish this project we started and get some results

    I havent been under there in a few years, you're prolly right.

    I have to dig up the article on the 'other forum', but I was the first guy to tear into an N55 when they were first released....I had pics of the downpipe, the turbo setup, etc.

    Wouldn't chopping the turbo off an N55 manifold and v-banding on a new one also bolt up to the N54?

    With some trickery, I'd image it could be kept twinscroll also (run divided up to a single WG)
