i have just bought another R33 that has port work and " bigger " cams..lol I have no idea what size they are.. but has SARD fuel rail and sard injectors don't know size... Molly fuel reg bosh 044 pump alot bigger garret turbo tail gate and 3" exhaust fmic BUT and here is the but.. it has NO intake, ECU and exhaust cam wheel... what I want to know is how much power can the stock bottom end handle??? I'm only guessing its stock and is there anyway of telling if I have forged pistons just by looking at the tops?? I will get a eftermarket ecu, adj cam wheels and a greedy intake... just not sure about the bottom end...... some one has spent alot of money on it in the past any help would be good
