I wonder if anyone can fill in a few gaps for me.....
I may have found a possible donour engine (clio 172 with loom and entire inlet + pos ECU) for my project at a very attractive price (It's not nicked! it's through a friend).
Now i know it's the same block as the Williams F7R has the same crank, bore and obveiously stroke. Now I assume that it has different pistons & ringpack, or ringpacks atleast to cope with the higher piston speeds (is it 7200rpm?.... on 172) and wonder wether the conrods are different too.
On to the head, now being unsure of too much detail on the 172, I know it has variable valve timing, Is it on inlet or both? Also is the port size, shape and angle the same as a meggy head (pref post 97) and valve size and combustion chamber shape the same?
Also :lol: if anyone knows of any other anoying differances that might cause problems.....
Cheers for any help, Jonny
P.S. Throttle body, all sensors, loom, ECU and cams might be up for sale soon.....
