i have a 92 k1500 305 and i want to get rid of it and im looking at a 6.5.
whats the differents between the s and f vins.
where could i get a wiring harness for a 6.5
is there a diffence between obd1 and 2
what r some good upgrades
and i have a 5 speed in it the shifter come out of the top center of the trans what type is it 3500 or 4500 and would it hold up to the 6.5
thanks

 

s vin trucks have egr and are less powerful and are usually on lighter duty trucks. its the opposite for f vin. best place for a wiring harness would probably be a wrecked truck in a junkyard. a nv4500 will hold up to a 6.5 not sure about the nv3500.
good upgrades are the same as other diesel trucks. exhuast, gauges, tune, and different turbo

 

The s has egr and the f doesn't. There are differences between obd1 and obd2. If you buy a 93 or older turn the pump up and add more turbo and go to 4" exhaust. If you buy a 94 or newer get a better ecm a boost controller and 4" exhaust. I would also put a fluid damper on ether one.

 

The diff betwen S has EGR and F don't


I would look in junk yards or go Car-Part.com--Used Auto Parts Market
just remember go with the right harness if it OBD1 or OBD2 they both diff

3"down pipe 4"exhaust back,gauges boost,EGT,and trans if you go auto,chip or reflash depend on what yr you go with turbo master ,97+ air system , put the PMD in front bumper

think would want to go with the 4500

 

What transmissions came in the 6.5 1500s?

 

only 4L80Es in the 1993-1998 years. lots of different trannys for 80's diesel half tons

 

That 4L80E is bullet proof.... I love it.

Also, NV4500 will hold up to the 6.5 forever. LOL. The cummins throws out way more hp/torque than a 6.5 will ever hope for. And, being a 6 cylinder, it's a rougher power harmonic than the smoother running v8.

That may actually explain why dodge has SOOO many tranny issues behind the cummins.
