hi need advice on building a 2.5 from my version 4 sti.

would like to know what bits are needed and where from and roughly how much its cost ppl to have it done. thanks

 

RCM do a complete 2.5 shortblock for about £1750+vat
its a standard type engine depends what you want to make power wise,
I have a full forged 2.5 and it cost a mint and we learnt a lesson
Next build for over 500 hp will be a 2 litre as the 2.5's are 25% more capacity but you dont get 25% more power and you do get 50% more weakness

bye the way thats just my oppinion and not up for debate
