I read a while back an article PPman posted about internal modifications that can be done to the NX76, (and any other Nitro engine I guess), to improve air flow inside the engine and so increase efficency and performance?

Well, after my original engine snapped its con rod last week [&o], I though it was time for a new one to get all the new mods Cen has been doing to the NX76, (Redesigned crank, carb etc). So I purchased a new GST sourced Block, (with crank & bearings), a piston and sleave and also what I believe to be a new carb with the redesigned needles that are easier to tune and set up, (Or so Cen say ).

But before I put it all together, I was wondering whether to take my Dremel to it [X(] and improve its breathing.

So, does anyone have experience of porting and flowing an NX76/Nitro engine?

Any results/conclusions you'd care to share?
