Oooh, I'm really confused now
The shells that were on the conrods and crank that I am using to replace the wrecked one were from an R-reg 2.0 CF2 engine. The number on the shells is 7646454.
ePer says that these were replaced by P/N 71728417, which (according to ePer) are 1.8
Class A (SP=1,527-1,531)
The shells that were on the wrecked crank (2.0 CF3) are 46738752, and were replaced by 71718342, and are also SP=1,527-1,531.
71728417 is for M3/M5/M20 engines (2.0L)
71718342 is for M2/M15 engines (1.8L)
Maybe someone in the past has changed the crank in the donor engine...or...bought the wrong shells.
In which case, should I order the 2.0 shells or the 1.8 shells???
Either way, I need the SP=1,527-1,531 right????
