Hi! Which turbocharger would you recommend for the S4 C4 engine with 230 hp? The engine was developed by my S4 and completely redesigned and optimized and is now installed in an Audi 80 B4 with front drive. Now it’s actually only about the turbocharger because the original one is still installed. Power should be achieved thus between 370 and 400 hp around it. Fan manifolds, optimized charging air cooling, suitable injection nozzles etc. are available – it’s all about the loader. What do the experts say, for example: Garrett Gt28rs, K29, T3/T4 Turbocharger, Garrett Turbocharger GT3076R etc.? Which would bring the corresponding performance and be the easiest from the installation? Price should not exceed about 1000 euros. Is this feasible? I am grateful for any information! LG Peter
