325e crank in 323i please help

[Griffffo]

hi all is it possible to fit the 325e 81mm stroke crank into the 323i 2.3 while keeping the stock jetstronic, head, pistons/conrods? I am desperate to know so please help!!!
thanks

Stock 323 is 76mm so unless you modify something your gonna smash the engine up - crank lengths are all on the e30zone wiki, as are the piston dimensions. Alpina did some interesting 323i engines so take a look at the c2's

thanks I found that the hartge h23 h26(323i version) and alpine c25 used a bigger crank whilst keeping the 323 block and standard head with jetstronic they just upped the compression to 10.1:1 with new pistons but did they change the conrods to 2.5 130mm? & did they keep the 2.0 and 2.3 80mm bore?

if you have a hartge or alpine please comment to!
