BMW M44 Engine to Create a BMW S42 Euro Racing Engine Replica


















  • M44 block bored out to 86mm to accomodate the Euro S50b30 pistons

Pistons: Left M42, middle S50 (decked), last STD S50
  • Euro S50b30 pistons decked 3.8mm and pocketed
Pistons: Left M42, middle S50 (decked), last STD S50















  • M44 connecting rods with custom small-end bushes....M44 rods are lighter than M42 connecting rods and contrary to popular belief they are forged)


  • Stock M44 big-ends and main bearings

  • Fully balanced bottom-end

  • Lightweight flywheel



Here's the rods: Left M42, next M44, next M47, las
 
  • M47 (E46 320d) crank with 0.5mm machined nose so the pulleys fit   NOTE - One important thing about the crank swap... The M47 keyway is closer to the snout of the crank than for the M42/M44. The stock key location on the M47 crank engages about 1/8" only of the M42 timing chain sprocket. You need to either have another keyway slot cut into the crank (best) or extend the key father back so that it engages more of the sprocket..."There's no replacement for displacement." This diesel engine crank increases the stroke by 8mm and displacement by 8.5%. You'll increase torque as well with the now longer 88mm stroke.
















This high output configured engine has a Stock M42 head, so far, head work and Cams would obviously increase HP in addition to these significant bottom end upgrades.


  • AFM to 3" MAF conversion (E36 328i MAF) the engines found on E30's use a MECHANICAL component called a AFM (air flow meter) to measure the amount of air going throw the intake. In this way, the computer can calculate the amount of fuel to inject in each cylinder. They stop using this AFM component around 1992. While there is some dispute regarding when the AFM was removed from production and when the MAF began [it is thought by some that BMW didn't switch to the MAF until the M44?], they replaced the AFM with a MAF (mass air flow meter) which is an ELECTRONIC component used to measure the amount of air going throw the intake.

 This is the diagram for the AFM to MAF conversion.



  • 80 degree thermostat
  • Custom 6mm duraform spacer gasket for intake manifold (keeps intake mani ice cold)
  • Stock M42 header, so far
  • TB water line delete
  • Euro M3 injectors
  • Fan delete mod
  • Dastek unichip
  • CAI
  • 11,6:1 compression
  • Current rev limiter @ 6750rpm























Future Modifications:

  • Euro M3 ITBs
  • Euro M3 solid lifters
  • 34mm intake valves
  • Gasflowed head
  • Bigger cams (don't know how big yet)
  • Custom header (4-2-1 48mm runners)
  • Up rev limit to 7500rpm




These S50B30 throttles bodies will be later fitted to another cylinder head. Still need to get another M42 head which will be gasflowed, bigger valves, better valvetrain, solid lifters and custom billet cams. The intention is to use the first two and last two throttle body sets. The fit to the head is like the ITB:s was intended for the M42. Additionally, S50B30 plenum chamber, ram tubes and rubber boot for the MAF.  The builder will cut cylinders 1 and 6 off and weld it closed. Its made of aluminum.

Engine

Stock 1988 325iS Engine:




BMW M20B25

The German version of the M20B25 produced 170 hp (130 kW) with a catalytic converter and 171 hp (128 kW) without. It featured the newly designed "885" head featuring an open, higher-volume combustion chamber design. The new engine had an 84 mm (3.3 in) bore, and 75 mm (3 in) stroke. The redesigned pistons and combustion chambers made better power, resisted detonation better and had higher thermodynamic efficiency. It was equipped with Bosch Motronic 1.1/1.3 Adaptive fuel injection. The new 12 valve engineering gave M20B25 the name 'verschieden', meaning 'different' in German. The engine is often referred to as 'the differing one' due to the anomalous valve system. With a minor modification that adjusts the idle speed of a cold engine, the 325i fulfills Euro 2 emission requirements in Germany, resulting in a lower tax compared to Euro 1 (as of 2005).
Applications:


Upgrade Engine Swap: 

BMW S50B32

The S50B32 was an evolution version of the S50B30. Power of the 3.2 L version is 317 hp (236 kW). Improvements over the previous 3.0l version include Dual Vanos operating on the exhaust camshaft as well as the inlet camshaft, increased compression ratio to 11.3:1, reduced valve stem thickness (and weight), and higher redline. This engine has a bore of 86.4 mm (3.4 in) and a stroke of 91.0 mm (3.6 in) giving a displacement of 3201 cc. It has a maximum permissible speed of 7600 +/-50 rpm, and a permissible constant speed of 7400 rpm. Power output was rated at 321 PS (236 kW; 317 hp) at 7400 rpm, with a torque rating of 258 lb·ft (350 N·m) at 3250 rpm.
Applications:
  • 1996-1999 E36 M3 (except for the U.S.)
  • 1997-2000 M Roadster (except for the U.S.)
  • 1998-2000 M Coupe (except for the U.S.)

BMW Alpina 2.7 rods piston m20 323i 320i E21 E30 e28

Here I offer a set of short rods for m20 engines. With this rods you can increase the volume on 2.7L to increase the power. Unfortunately i dont know which engine they came off of..these are in perfect used condition all but bearings should obviously be replaced. The length from center to center is 130mm.

dreaming....

i have considered many things in regard to this car...the price seems to be in an upward pattern particularly given the economical situation in the country...e30 M3 are bringing a premium price...the iS is not far to follow the trend...

. . . possibilities for a transplant or for the M1 clone in Canton, Ohio . . . .
