i though the same thing. compared the two i have. 1 from a 100kw 4age(7 rib) and the other from a 5 rib big port 4agze. only difference i found (The hard way) was the keyway is not the same size although i have not weighed either. got almost 5 degrees of play with the gze ballancer on the Ge crank. will have to get my hands on the GE ballancer and live with it i think. from the research i have done there is only about 700grams difference but unsure on which i have as the same page states 4AGE engine had two depending on which model. so anyone out there with a 100kw GE crank out of there motor it would be a great help if you could weigh it and post the results here.

Hi all, i have a bit of a problem. Some fool at the engine shop decided to machine the wrong crank for my new engine as i took 2 in with oil pumps still attached as the damn timing gear didnt want to budge from either and they screwed it up and machined the 4age one. Which i found out after rebuilding, attaching everything, new turbo manifold the lot and then came the harmonic ballancer. Well it has a different Keyway doesnt it. which wont be such a problem as i can get my hands on a 4age 1 i gave my mate. but as its going to be turbo a forged crank would be best. which brings me to my question. Is there any difference between 4AGZE and the 100kw 4AGE cranks? thought i better find out the correct info before i decide to loose my brain at the shop. ive read something about there being 4age's with the same 42mm crank as a 4agze but wondering which ones? Thanks for your help.
