I was torn between the Chinese rods and the MED ones for the next race engine. Ultimately went MED rods with MED pistons. So far haven't regretted spending the money. It would be a different story if I was only upgrading a street engine but for something that lives it's life at 8k, I'd like to not have to "make it right".

Never quite understood why majority of performance con rods are H beam design, is H beam easier to make or stronger, when compared ?

I beam is FIA legal in many cases.

This video will tell you everything you need to know about which rod design is better Clear as mud.

Personally I go for H-beam, they are like for like lighter from the same supplier, Robson do an option that was developed for the Millington diamond engine and is used by Swiftune where the channels in the sides of the rods are cut far more square rather than a single radius, this saves a lot of weight.

All these cheap rods I've come across are Sintered, none have been forged, though, there maybe some out there.

Using the Sintering process to make rods is fine and loads of OEM rods are made this way, however, other that closing and honing the Big End, there's nothing else that can be done with them when reconditioning one of these rods, They cannot be straightened like forged rods as they will crack and break. In a pinch, the little ends could be bushed and bored true, but often there's not enough meat in the little end to do this.
