I have been reading through threads, other posters builds, and listened to countless opinions. To be quite honest, I still need help on my decision of what to do, what would be best suited for my goals. Ive determined im going to use a stroker kit in the FRPP Boss 5.0L MOD block, hopefully giving me a solid 5.3L. The final problem is, whether to go with the single 76mm or twin 61mm turbo kit from Hellion. The car will be mostly street driven, but the big reason for going with the turbo is that it will occasionally see some auto-x and road course time, and the instant power from the large blowers is actually detrimental to the handling of the vehicle. for power goal, i plan on making a modest 500 to 600whp for the street, but i would like to be able to break 1000+whp; not to use necessarily, but more or less just to say and know that i can (as childish as that may sound). I know the single 76 doesnt hit full spool till 3500 to 4000rpms with the 4.6, but i almost think that with a 5.3L, a single 76 would be perfect not only cost effective wise but in simplicity too. long in short, to any professionals on this site with lots of knowledge on building turbo cobras, for a mostly street driven car, with a 5.3L stroker, what would the recommendation be?
