I have a 99 24v with a drag comp and Bosch 300 injectors. I have a PDR HX40 turbo on it and love the way the turbo woks on the top end but hate it when towing and in the mountains I usually tow at 6000-10000 feet. I really like the way the stock Hx35 woks for towing but my egt get way high when running on 5x5. My question is can I build a set of twins using my stock hx35 as a top turbo and use the PDR Hx40 as the lower turbo?
