Peter, it was just the rods that were reportedly stronger, pistons are the same and good for power levels of 500bhp+
Feel, I'll try and explain what i meant
The part numbers for both 210/225 conrods are the same, but that doesnt neccessarly mean that they are the same! I suggested the 225 BAM rods may have superceeded the 210 AMK rods. Perhaps the company that supplied SEAT with rods had a new batch, had them redesigned due to costs? Maybe the new batch was made to a different tolerance?
Why did they change the pistons and rods from the original 150bhp engine? Surely they could have just used the stock/supply that they already had from the 150bhp engines? It was probably down to cost that they redesigned the internals. The 210 perhaps used the left over parts from the 150bhp engines and when they ran out they then got a whole new batch of cheaper BAM internals?
I dont know buddy

but i dont know where this myth has come from either?
In not saying that the 210 engine is definitely stronger, i merely stated that the myth about them has been going around a while! Who made it up, where did it come from?
I have been testing the 210 AMK for 18mths now at quite high power and extremely high torque levels without failure so far, touch wood! I may in the future change the rods to allow me to fit 100bhp nitrous jetting along with the hybrid so hopefully ill be able to put this myth to bed when and if i decide to take the car that far
