      well figured i would start a new thread.just a quick background.did the whole build on my explorer but built it using stock head gaskets and head bolts.did it really as a safety net and i just couldnt afford head studs at the time.well to say the least i blew the head gaskets off from it wile i was in the mountains on a forum trip about two years later.

      i picked up a 1994 ranger,its got the 4.0 OHV and is a 5 speed 2wd.the plan is to pull the motor out of the explorer and rebuild it.

      this thread will basically cover the rebuild and build up of the new ranger.it will basically end up as a street race truck.ive named it Rudy:D:D so let the fun begin.

      next i got ride of those dumb ass stickers.there was 28 of them on the truck and the ones up top,the glue baked into the paint and wont come out but looks 100% better.i also did a shackle flip in the rear to try and level it out some.it will be getting an 5.0 explorer 8.8 3.73 with an extra clutch and sua.should give me around 5-6 inches of drop.im getting dream beams for the front for 3 inches of drop.also doing the 95 spindle and brake upgrade.also mounted a new set of headligts.

      dropped 2" in the rear

      Looks good man, you still trying to find new pink flame stickers to replace the originals?

      Maybe Ben can help?

      Why not make the ranger able to tow your explorer around since it'll be a pig...

      Don't wanna put that kind of mileage or stress on the SC motor.with just a fresh basic ohv in the explorer I shouldn't have to worry about reliability.

      Saturday me and xeek drove 4 hours round trip to get the aux tank and I get there and they don't even have it!!! I called wed to make sure they had it then I called back Thursday to get them to measure the sender hole and everything. Both times they assured me they had it and even called me back with a description and measurement of the sender.I get there and the ranger didn't even have the option for a aux tank.the f-150 next to it did tho!!! They said sorry about a billion times and gave me $30 to help with gas.atleast they did that!! Also my truck only got 20.7mpg!!! It was windy as **** out and it needs a tune up pretty bad.NOT HAPPY RIGHT NOW!!! Back to the drawing board!!

      toady i did get some goodies tho.i went to pick and pull and got my no ac heater box and also got my 95 spindles.im going to be making a bracket that will alow me to the ST 12" rotors instead of the stock 10.25" over on rps they were making these brackets but stopped.if i can turn them out cheap i may end up making them for sell.here is a link to the thread and some pics of my new finds:D

      Good thing you didn't turn the heater on.... that could've been very bad.

      this is going to be alot of pics.starters i got a new set of tail lights put in and they look alittle more ricer than they did online but think they are alright.

      next i got all the measurements and mock up done on the ST 12" rotor swap.i ordered some fresh metal and as soon as it gets in im going to machine all the parts and weld them up.so right now im waiting on parts and the ST rotors to come in.ill show what has to be done and the final bracket,but dont think ill be releasing the measurements or cad drawings.i may end up selling these as a big break kit,so ill show what needs to be done and if you wanna make them your self your have to do the math;)

      lights
      [​IMG]

      LOTS of pics for you and when the bracket is done ill show that,these are mock up with scrap i had around the shop so i could pull measurements.these are the 95-97 spindle upgrade so you have to have 95-97 or this spindle upgrade on your truck to begin with

      stock 10.25'' rotors
      [​IMG]

      mod for ST 12" rotors.(just mock up,not actual bracket)
      [​IMG]

      and now bunch of pics to show what was done,basically the spindle and caliper brackets have to be ground or milled down,squared up and the bracket holes need to come up..
