I just ordered an intake for my 95 ram 1500 5spd 3.9.
my question is are there any differences in the 3.9 5.2 and 5.9 throttle bodies it says that it is for the 5.2 and 5.9 only but it has a compatibility chart and when I fill it out it says it fits?

 

What intake?

The 5.2, and 5.9 are eight cylinders, the 3.9 is six, so, the intake manifolds will NOT swap. The six *might* use a smaller diameter throttle body, but, don't know for sure.

 

I am sory I for got to put in that I am talking about a CIA NOT the actual intake are the throttle body diameters the same for the air cleaner?

 

Yep. Those should be exactly the same.

That said, a CAI will do you zero good on any of the engines. They all draw air from the exact same place the stock setup does, (thru the passenger side fender....) so, the stock system IS a cold air system. You won't see any gains at all from replacing it, it'll just be louder. Spend the money someplace else, where it'll actually do some good. (skip the throttle body spacer too. )

 

I had all ready pulled the trigger on the CIA 2 days ago. The mane reason was looks/sound the other was that I think it would be a little better with a smooth round pipe then a rectangle with accordion tubing.

If smooth is bad and accordion/ribbed is better please explain.

I agree on the throttle body space I do not think the do any thing that you will notice. The only thing they do is add a small amount of plenum volume and that was my only interest in one.

what is thout of the ebay shorty headers? https://www.ebay.com/itm/FOR-92-02-R...s=aid%3D222007

I am planing to replace the the pcv and breather with these https://www.ebay.com/itm/Mr-Gasket-2...xaKKdU&vxp=mtr

I want to go to a v8 one day but plan on keeping the 6 for quit some time. What can all be done to it? Do oldschool/taditional hotroding methods ei 60s 70s 80s work

 

Although this is geared towards a Dodge Dakota, the same principles apply. http://www.hotrod.com/articles/mopp-...owered-dakota/

 

Sure, the smooth tubing will flow better..... but, you will only see the benefits of that in the very upper end of the RPM range. (a place where you spend very little time.) And, for a little fluid dynamics..... 80% of the flow thru a tube is down the center, as you get closer to the boundaries, flow slows... so, at the inner surface of the tube, the air really isn't moving all that fast. (in comparison the flow down the center.) The stock system flows plenty of air to feed the engine. Most of the benefit you see from a CAI is from the less-restrictive filter.... of course, it's less restrictive because it doesn't filter as well... So, six of one, half-dozen of the other.

 

thanks that is very good info I plan on doing some thing on that list.

I have more questions though. regarding the the CIA from ebay it says that it is for 5/2 and 5.9 v8s only this is not the case tough I did some googling and saw some old posts here and some other places and it seams that the v6 and booth v8s have the same air hot diameter?
can I put 5.9 v8 or 8.0 v10 injectors on my v6 the reason I left out the 5.2 is I think they are the same since the v6 was made from the 5.2?
last question dose any one know why they made the v6 from the 318 and nod not the 360? I truly think it would be a much better engine if they made it from the 360

 

I *think* the 3.9 is just a 5.9 with two cylinders cut out. A fair few parts will swap between the two. (of course, a fair few parts will swap beteen the 5.2 and 5.9 as well.....) Trouble is, none of 'em were really 'good' designs. Underpowered, gas hungry, etc.

Putting in bigger injectors won't really help you. The PCM will figure it out if they have a different flow rate, and compensate for it while in closed loop. In open loop, it would just run a bit richer.... Of course, if your current injectors are clogged, or simply just not performing to spec, it may be an improvement. But, you would get that same improvement from a good set of v-6 injectors.....

 

it says this on wikipedia

The LA 318 was a 318 cu in (5.2 L) relative of the A 318. Like the A 318, it has a larger cylinder bore at 3.91 in (99.31 mm) as well as a stroke of 3.31 in (84 mm).

The LA 360 cu in (5.9 L) has a 4.00 in bore and a 3.58 in stroke.

The 239 V6 is a 239 cu in (3.9 L) V6 released in 1987 for use in the Dodge Dakota and a replacement for the older, longer slant-6. It is essentially a six-cylinder version of the 318 V8.

going by these figures if they would have made the v6 form the 360 witch is hat I think they should have done it would have been a 272 not a 238/239
