hello guys,
i would like to know what parts are exchangeable between all r5 engines, i mean pistons, rods, crankshaft etc., or from what engine version are the best pistons or rods... or if its possible to put 2,4 crankshaft info 108kw for example and what modifications will be needed to do something like that?

i dont want to buy a 2,4 r5 and put it into my car, i will be repairing whole engine so i want to do some performance upgrades at once.
my engine is 108kw version and i have these parts:
-vis head
-vis/20vt cams
-20vt inlet plenum with throttle body
-20vt injectors and ramp
-20vt lightened flywheel
-dedra integrale pressure plate

do you know about some really good upgrades for this engine ? IT HAS TO BE N/A!!!

i will have to change piston rings so i want to check everythink around crankshaft, than i got the idea about 2,4 crakshaft so if you guys have some info, please let me know
thanks!
