Rene,
I offer two basic setups. The Jaguar /Eaton M112 with the smaller intercooler is the more cost effective setup. The total cost on it for an 86 would be $4600. This would be with me providing everything including a re-built Jag/Eaton M112 SC. You could do this same setup for quite a bit less by buying some of the off-the-shelf parts, like the fuel pressure regulator from e-bay. The Jag/Eaton M112 setup can be done for $3800 if you find the right deals one-bay. The Jag/Eaton M112 setup would yield around 500CHP max.
The Twin-Screw setup is a step up and has more potential. 500CHP is really just the begining for this setup. The potential is there to make a whole lot more HP but this would take quite a bit of knowledge and more $$$. If I provide all the parts this setup will cost $5835.00 including the big intercooler. You could save about $400 buy buying the off-the-shelf parts off e-bay and from summitt racing.
