i waana swap my 1.7 from my ram to my durango but , i hear that some specs of the motor is difftrent ? is this true ? i also swapping fastman and my airgap and getting heifever to write a tune ! what all mods do u guys have ? the one guy said it blew up his motor because the specs arew diffrent in the durango

 

Well the specs aren't any different that I know of. We always kinda looked in the ram section for the performance write-ups. We like the home brew ram air $5 upgrade. Plenty of threads on that. When I get my transmission build done I'll do a review of whether that helped performance at all.

 

well im fro the ra foru and i just swapped the fastman throttle body and intake and already ade a diffrence i mailed y sct tuner out that was on my truck to get the tunes written for my durango . does anyone know the sizeof the cat on our truck ?

 

the durangos had hi flow cats already dont replace the factory unit unless it is bad

 

Trust me; you don't need a bigger cat. My old 1998 with 5.9L 4X4 was bored 30 over, P&P heads, Fastman TB, and custom work on the intake, plus lots of other upgrades….LOL. Absolutely no issues on exhaust and I had a factory CAT with 3 inch back magnaflow single.

Pull'in 9000 lbs (later weighed trailer and verified) with 750 tongue weight I could still break the tires loose when taking off with 3.92 gearing, new BFG A/T KO's at 31X10.5X15 inch tires. Now hows that for a build?
