Ok this is the problem I have, I want to build a sbc turbo motor but I am having troublt finding a kit. I have an older non ls/lt block that I will be using and i want to run a carb. The engine will be going in a 1987 S10. I want to make about 450-550 at the wheels. I plan on using a summit top end kit that has edelbrock performer heads also I dont know if I will use a roller cam setup or not. Now my question to anyone who can answer is where do I find the turbo parts. I mean the turbo both hot/cold side, along with the waste gate I can find almost everywere but the exhuast is were I am coming up blank will I have to have one made for me or is there a company who makes them for SBC already? Any help that anyone may have is greatly welcomed.  

man i dont know how much the top end kit cost but u can make that kinda power nat. asperated with a good set of heads and 383 cubes and no headach trying to fit a turbo under thet small hood that will be fairly tight with the v8
if its a street truck i would use a roller    all out race truck eather way  

Turbo City in Claifornia either the city of Orange or Anaheim?

They have all the custom turbo stuff or can point you in the tight direction.
