hi guys

How much longer are 1300 conrods compared to 1200ST?

What would be the benefits of fitting 1300 conrods in a 1200 block with standard 1200 pistons. Would you use the 1200 crank?


many thanks

1200 pistons , coupled with 1300 conrods and crank gives you 1400 there abouts

By comparison

1200 are larger pistons than 1300, but short stroke

1300 have smaller pistons than 1200, but longer stroke

Haven't got any figure in front of me, but any handbook/manual should have the details

read the above thread about the whys & why nots.

the 1300 conrods are actually shorter than 1200st. as the stroke is longer, they need to be shorter

there would be no benefit in putting 1300 rods into a 1200 block, unless you were planning some crazy turbo thingy....
