Does anyone have the "recipe" to the Hartge and or Alpina M20 engine. Both companies put out a 190 HP and 210 HP variation of the engine. If anyone has that knowledge of what either company did to acheive that level of power, I'd like to be included in the know. Thanks

190HP H26 : PORTED HEAD,CAM(272'),LARGER VALVES, EXHAUST WITH HEADERS,REPROGRAMMED ECU, PISTONS. in simple terms<br>205HP H27 : ABOVE WITH 325i HEAD AND 325i VALVES AND THE TURBO CRANK <p>THE CURRENT MOST COST EFFECTIVE IS TO USE TURBO CRANK, MAHLE 10.2 PISTONS , 325i HEAD, SUPERSPRINT HEADERS AND EXHAUST, AND 288 SCHRICK CAM. BECAUSE HARTGE IS NLA FOR e30

The Hartge H2.3 had a 80mm bore x 76,8mm stroke for a capacity of 2.3 litre, power is 170HP<p>There is the H2.6 with 84mm bore (same as the 325i bore) and same 76,8mm stroke as the H2.3. Power is 190HP.<p>And the H2.7 with 84mm bore and 81mm stroke. Power is 205 HP.<p>The long stroke crankshaft belongs either to the Eta or to the Diesel engine, the later being forged and stronger. But everyone building a 2.7 uses the Eta crank as they are almost free from the junkyard.<p>Compression ratios are around 10.2 and camshaft between 277 and 288 degrees.
