the 2.0l cams are supposed to be the same as 130spec cams although im not 100% sure that they are.
i believe the inlet cams have a different code but to be honest they cant be far different.
exhaust cams are the same i understand.
the advantages will only come when fitting all the 130 spec gear.
105 to 130 consists of cams/ throttle body and ecu.
so i suppose you could see 5-10 hp with just the cams.
you wont get 25hp increase unless you have the lot.
pm me for info and some spares.
if you have 115 spec then you are only 15bhp off anyway.
