*clears throat* ok heres the deal

a bone stock c4 from a fox body will hold up to MAYBE 350HP/tq if your going to get any kind of built transmission your looking at easily $3000 or more. trans brake and manual shift solenoid's are even more. dont forget that you are going to need a torque converter. that can run you anywhere from $150 to $1000 depending on diameter, and lock up speed.

chances are when you buy and adaper kit it will only include the adapter plate itself and maybe a trans mount. you will need to take your tranny yoke to a drive shaft shop and have them make you one.

Unless you're building a big power drag car a C4 trans is a giant waste of time
