It's got to be a Silvertop mate as its a Silvertop 1.8 turbo I'm running already. Budget isn't the right word...! Ive spent well north of 3k on bits so far and I haven't built it yet! got tubular exhaust manifold , 800cc injectors ordered. turbonetics to4b hybrid. I know about Oil pump risks but I'm going to fit an Oil pressure warning alarm and see how it goes. Can't afford dry sump at the minute! And some oil pumps have been ok...
