I have a 97 cobra with a forged bottom end with 8:7:1 comp. ratio with a GEN 2 on3 forward faceing kit. Only two problems I had with this kit is the v-bands whitch I upgraded and the turbo.the turbo has about 1k on it and oil seals are already bad and doesn't spool at idle I'm making 500rwhp at 13psi I have spark blow out around 5200. So my question is what type of turbo brand and size would be good for this combo? Probly never going to exceed 700hp on car.any help is greatly appreciated.
