what are some quick, easy and cheap mods i can do to my 318

 

You can do the "kegger mod" where you cut down the runners in the intake manifold, and bore out your throttle body just a little bit and put on headers and a low restriction exhaust. All that could potentially cost less than $200. But you have to do all of those things if you want to see any gains, doing one of them won't help.

You can take off the big, heavy mechanical fan and put in an electric fan on it. That could cost less than $100.

 

Under Drive pulleys. more Rear weal HP and better MPG all for about $100. I gained an extra 20 - 30 miles per tank and freed up 7-10 HP that the alternator and water pump were using.

 

nitrous....

 

Um, nice try Pbadgley, but a 90 amp alternator running at 14 volts uses 1.68 horsepower from the engine... assuming your using every bit of those 90 amps, and you'd have to be running some crazy electronics to pull that kind of current. So if you took the alt off, you'd potentially free up 1.68 hp, so putting a smaller pully on it and running the standard set of electronics may save .2-.3 hp. I don't know about the water pump, but it can't possibly save that additional 6-9 hp (to get up to your claimed 7-10 hp gain) without ineffectively cooling the truck.

I would personally NEVER sacrafice my trucks electrical and cooling capabilites to free up 2 to 3 hp, cause thats all you're really saving.

 

New sensors is always a good thing. Demagnetized sensors suck!!!

 

Lol, good point Az93Dkota. How could we all overlook the obvious... a good tune up is the number 1 way to get a bit more power/effeciency out of any engine.

 

i picked up a set of under drive pulleys but couldnt use them since my water pump wouldnt allow me to use the water pump pulley and i dont use under drive alt pulleys so i didnt wont to use just the crank pulley.


certain 2nd gen cold air kits will work

take the cat out and do a 3" exhaust. put 92/93 manifolds on as they are 2 1/8 and the 94^ manifolds are only 1 7/8. the kegger intake is also a good idea. if you really feel into it you could pull your heads and port them. im sure theres also some other things as well
