M30 "Big Six" Complete Engines 2.5, 2.8, 3.0, 3.3, 3.5, 3.7 Liter Korman offers 4 basic rebuilding configurations for the M30 engine, Stock, Stage 1, Stage 2, and Stroker Engines. All our street engines come with a 2 year/24,000 mile warranty. All the listed engine packages are 50 State emissions legal unless otherwise noted Stock Rebuilds Our stock rebuilds are assembled to BMW specifications by our experienced and dedicated technicians rather than off a mass production assembly line. Korman engines are assembled with meticulous craftsmanship, precise machining, and detailed blueprinting. All of our boring is done with a torque plate for exceptional bore roundness and long engine life. These hand built engines are available at prices comparable to a factory reman units which offer only 12 month/12,000 mile warranties. 2.8/3.0 liter carbureted P/N 11006000 2.8/3.0 liter fuel injected P/N 11006010
Stage 1 Engines Korman Stage 1 Fuel Injected Engine-2.8/3.0 Liter Our Stage 1 rebuild will provide a moderate increase in power through the use of our proven performance techniques.

Weber Downdraft Conversion-2.5, 2.8, Bavaria, 3.0, CS Two Weber twin choke downdraft carbs bolt to your stock manifold to replace those troublesome, hard to tune and expensive to repair Zeniths. Our kit includes a water heated choke mechanism that connects to the original Zenith water choke fittings. The progressive linkage gives excellent fuel mileage. The mechanically operated secondary opens quicker than the vacuum controlled Zenith and provides smooth quick acceleration. We do not represent this as a high performance conversion. The throttle area of these Webers is not greater than the Zeniths. You get easy tuning, low maintenance, fuel economy, and quick initial throttle response but for more horsepower you must use the side draft Webers. This has been a very popular kit and most customers just wish they had installed them sooner! Includes two DGAV carburetors, base gaskets, two idle solenoid valves, complete linkage assembly, top quality air cleaners, fuel lines, water hoses and clamps. Detailed instructions are provided.

The original "POD" air filter. Cylindrical foam element. A heavy gauge steel spring maintains shape and prevents collapsing. Our dyno tests have proven this filter produces higher horsepower than the Lynx or K & N. Heavy rubber base with stainless steel clamp fits securely over air horns. Use one filter per carburetor.
ITG
Air Filters This new air filter permits use of short air horns inside for improved power. The red fiberglass reinforced plastic frame is covered with two layers of foam for a two stage filtering process. It seals better than the Lynx type filter and provides greater flow. Fits both Weber and SK side draft carbs. From England.
Lynx Air Cleaners A high quality foam element/chrome mesh air cleaner made in Australia, specially designed to clear the BMW brake booster assemblies.

E3/E9 Exhaust Korman-Stahl Headers These high quality headers provide a 6-10% power increase on stock engines, much more on high performance engines. Engineered for trouble free fit and long service. Also available with ceramic thermal barrier coating (described below) for additional performance, durability and improved appearance.
Notes: (1) Connector length to the center resonator pipe must be shortened. If a 4 speed model has been converted to a 5 speed, must trim the edge of the transmission support bracket. (2) Only for 3.0, 3.3, 3.5 engines over 270HP, must radius edge of engine casting for clearance. Exhaust Manifold Porting A careful porting and polishing of the exhaust manifolds. We then precisely mate the exhaust manifold gaskets to the exhaust manifold for maximum flow. Especially effective with Ceramic Thermal Barrier Coating. An excellent alternative where headers are not an option. All 6 cylinder P/N LAB18213006 Ceramic Thermal Barrier Coating From Aerospace technology comes this oven baked metallic/ceramic finish that is far superior to ordinary header paints. In salt spray testing where high temperature paints lasted 40-50 hours, the ceramic coating lasted over 5,000 hours. The ceramic thermal barrier finish also coats the inside of the pipe. The thermal barrier will reduce underhood temperatures and testing has shown horsepower gains due to combustion chamber stabilization and increased gas velocity. All 6 cylinder P/N 182110016

used in Formula 1, IMSA, SCCA and Pro Rally applications, Quaife
Automatic Torque Biasing Limited Slip Units are now available for your
BMW. Quaife units utilize a gear driven mechanical process to direct
power at an infinitely variable rate (as opposed to a fixed 25%, 40% or
75% rate) to the wheel with the most traction. Unlike the more
complicated and fragile Torsen design and the BMW OEM clutch pack
limited slip units which tend to transfer power abruptly, the Quaife
units are simple and rugged in design and provide a very smooth power
transfer between the two driven wheels. Quaife units have proven to make
as much a one second per mile difference in lap times on road
courses. We can provide you with the unit for your own installation, or
install it here in our facility.
