you can buy used superduty coolers for $100-$150
then its just a matter of mounting it in there, if you are a good fabricator you can make the pipes and mounts and use the intake spyder off an early 99. probably get all that done for around $200
if you want to buy an instal kit, dpppower.com has been selling IC install kits that include everything to put it in other than the cooler for 400-500 IF I rember correctly. best thing to do is just give them a call.
