The cost will vary depending on what you need. The 4 spd to 5 spd 'kit' prices assume several things. Some of these include that you send them your existing bellhousing to be remachined for the Tremec. If not then a new Kiesler unit is about $300. A pistol grip will run you about $140? if you don't already have one and a decent clutch and press plate will be another $300 or so. They will also make up a new driveline (incl in kit) but they require that you to first install the trans, measure the distance, and then fax them the info. Then about 2 weeks later you get your driveline. My 4 spd to 5 spd swap cost me $4,300 + or - but I upgraded the clutch, bought a new press plate and pistol grip and bought their bellhousing. I think the minimum you could get away for with the basic kit will be around $3,500 after shipping, etc.
