I have a few questions about big turbo conversions. The A3/S3 has forged pistons, conrods and crank as standard. However, the conrods seem to be the weak link in the engine. Is it the actual conrods themselves or is it the rod bolts that are weak over 335lb-ft? Also, why has nobody gone for more than 340bhp - there are turbos out there like the GT28R (good for about 370bhp) or T30 that is good for about 470bhp. Surely with uprated conrods it would be possible to get over 400bhp safely - no?
