The tried and tested Turner Motorsport M50 Manifold Conversion kit includes everything to fit an OBDI M50 manifold to an OBDII M52 or S52 engine (1996-1999).  It takes the guesswork out of adding the M50 manifold to your engine.  The kit includes a CNC machined adapter with all hardware and gaskets that allows the freer flowing M50 manifold to be installed while maintaining full function of M52/S52 components including factory PCV cyclone/oil seperator valve.  No vacuum leaks.  No check engine lights.  Another benefit is that the entire kit is completely reversible.  Turner Motorsport has dealt with the problems from other kits and this adapter block is by far the best solution.

 

With the introduction of the 1996 model year came the OBDII emissions compliant engine.  Among the many changes the OBDII engines received was a more restrictive air intake manifold.  Where the older M50/S50 engines continued to make power up in the higher RPMs, the newer M52/S52 ran out of breath, limiting high-end horsepower, but boosting low-end torque.  Converting the OBDII cars to the 1995 and earlier OBDI manifold is a popular modification to remove this high-rpm restriction.

 

The base price of this kit does not include the M50 manifold.  You can pick up a used manifold from a 1992-1995 E36 325i or a 1995 M3 3.0 liter.  You can find them in local junk or scrap yards, online at Craigslist or eBay or from various forums.  If you would rather not deal with the potential pitfalls of a used part, we can offer a new Original BMW manifold to go with the adapter.  While expensive, the new manifold is guaranteed to be in perfect condition with no cracks, warping or foreign objects hidden inside.
