hi, im new to the truck world, i recently bought a 91 dakota sport 4x4 and i dont have it yet but would like some ideas on what to do performance wise. I plan on running headers with true dual through a set of glasspacks or something and would like to get a LSD for the rear. I was also wondering if i could get a set of magnum heads and swap them onto my pre-magnum and what it would involve. Also would magnum headers fit on my pre-magnum? How much would a LSD cost? Should i keep stock gears? I dont have plans on serious off-roading. I do a fair bit of highway driving but still want the low end power.

what do i need to know about swapping the stock cam for something better?

thanks

 

I have heard that the mag. will fit the pre mag. as far as v8s go. I dont know about v6, which im guessing what you have. I would suggest is get a set of head gaskets to both and compair. A LSD might be about 500 or so. You could get a richmond Lock Right for 300. I have it, they work great. The only thing It is a full time locker so when you press on the gas it will stay locked up. but when you make a corner and let off of the gas it will unlock so you can make it. I would say step up just a little for rear end gears. If yo go to high you loss the highway speeds.

 

v6 or v8 mags will fit premag

 

shiat... i was so busy trying to get everything typed down that was in my head i forgot to mention that it has the 318 and i would just swap it out for a magnum exept the truck only has 131xxx km wich would be about 80 xxx ish miles i think

my biggest consern is if i start addin magnum parts is if my stock computer would cause me problems. Also what rear end gears would u recomend? i do want to keep my gas milage or as much as i can because for winter it will be takeing me 80km's every day....

ive been doing research and from what i can seem to figure is the magnums just had a diff top end but the bottem was still the same? so it seems that stuff should be very simialer.

p.s - i was looking at these JET Stage 2 chips.....

whats your say on them? other suggestions?

 

I was thinking about putting magnum heads on my 318 i am building, but according to allpar.com the pushrod geometry is a little to steep, so it is really easy to bend the pushrods. your heads flow pretty good on that engine, they have the spiral ports in them, i would just shave them down to bump up the compression, that is all i am doing anyways. I would reccomend getting the mopar performance computer insted of the jet stage 2, i have one and i wish i went with the new comp.!

 

yes i was reading about the mopar performance comp but i also read that you then need to run premium fuel, and that is something im not willing to do all the time..... i thought maybe the jet chip would show slight gains without the need of better fuel....

i dont know im just really learning as i go here

and thanks for the head info...i thought i went through allpar.com and couldnt find anything about the gen 1 dakotas, ill have to have another look sometime.

 

easy hp. take the shield of the intake. use a roto tool to cut out the center of the imtake block. cover with chicken wire to keep out bugs. put back on.. bang. you got rednek air induction.

 

You have to run high grade fuel with the jet chip too!!! i did the ram air mod..... it did not make any difference, flipping the lidis better.

 

I don't think you have to run preminum fuel with the jet stage 1 chip I think

 

yea, i did not think of that, i have the stage 2 and you can tell the difference between 93 and 87!
