Thinking of replacing my hiflowed turbo to a GT35/40R 0.70 / 1.06 internally wastegated turbo.
Has anyone else done this conversion and can you advise the handling ie lag, dyno results, drivability, when boost comes on etc.
Currently do drags and circuit in SII GTS-T with intercooler, Power FC, Hiflow injectors, Z32 airflow meter, fuel pump, fuel pressure reg etc. - acheiving 302hp in third gear dyno. Would really appreciate hearing from someone who has gone through the exercise - good or bad???
Cheers
