Whitney helper springs & rear sway bar, 4.0 ohv--Vortech supercharged, over 185,000 miles only isses were 2 thermostats ( one at 75,000 & 2nd at 160,000 ) and one alternator ( at 120,000-- stereo with sub & aux lighting present ). The truck has been extremely reliable/very fast--road trips very fun/ran 157 mph outlaw speed run ( 1998 ). note: also put a single turbo in the bed over the axle in a 96 extended cab 2wd 4.0 ohv, 5 speed manual, had a big sub box from the front of the wheel wells vented into the cab, used Thunderbird, turbo coupe hood scoops ( found in boneyard for 10.00 ) inlaid into pass side front of bed for air intake, battery & amps were on drivers side of bed next to wheel well, everything was divided & had a fiberglass tonnue cover, no other engine mods, sold with 110,000 miles, never had an issue. I still have a 97 4.0 ohv, extended cab, 2wd 5 speed manual, 208,000 no issues. these vehicles all driven hard, loads/towing/road courses/ various race tracks/every world ford challenge event/ multiple Naperville il. burnout competitions/cross country road trips. **( this has been stated as positive side of supposed 4.0 ohv durability issues ). Also I used to know a guy who had a rear turbo under the truck in the mufflers location ( he had been in contact with Squires Turbo Systems for sizing info ( he's the one that I got my info from--he's has since passed away ) he had over 350,000 miles on his 93 Ranger. *( also I'm biased to Vortech superchargers, my 86 Mercury Capri, 331 cid & the wifes 04 Mercury Maurader are Vortech Supercharged ( Maurader from 1 week after we bought it new ).
