It is unknown to be honest.
The 210 ''supposedly'' has stronger rods that will need to be changed when going beyond 340-350bhp power levels. However i dont think a 210 LCR AMK engine has been stripped down yet to see if they actually do have the stronger rods
No one has ever confirmed this so as of yet it is unknown!
As to the 225 engine conrod limits, well its obviously going to be
lower than the 210 AMK if it has the weaker rods, by how much i dont know
There's only a 1mm difference in pin size if there is a difference!
Pistons are good on both engines for silly power 500+bhp
Are you going to tune the car so its beyond 300hp? Ie a bigger turbo? If not then dont worry about the strength of the engine.
The normal remap route will only yield around 265-270bhp so well within limits of the 210 and 225 rods?
