hi, i have v6 edm impreza classic(gc8) 2lt turbo with jdm 6 speed driveline. i want to use rotated holset hx35 with my stock engine(about 100k kms). i have hx35w which has 12cm turbine housing and 58/83 mm compressor wheel(maybe i'll convert kts billet compressor wheel). i read holset threads on this forum and generally setups are twin scroll. i want to use spec c twin scroll header(legacy gt headers are very rare in my country) with t3 twin scroll up pipe. But first i want to build single scroll up pipe for my stock cast header. did anyone use single scroll up pipe with twin scroll housing? will this setup be too laggy? i saw single scroll header matched with ts housings but these cars not subaru or ej series engines. regards, semih
