Hey all, new to the board, wondering what i can do to get a few pony's out of my 302 with a low budget, as for right now I'm thinking about getting my stock cats cut out. Any suggestions would be awesome, its a 5 speed 2wd if that helps with suggestions. Thanks in advance,

Also what year would help but you're going in the right direction. Two key elements are to open up the intake and exhaust. Also, look into getting a set of underdrive pulleys. Never forget that a simple tune up can go a long way as well. (spark plugs,wires,cap/rotor and fuel filter)

 

I've got a 300 straight six, and it has a stock cold air box setup. I've heard guys with 302's put this setup into their trucks to help out, you could get one at a junkyard awful cheap, and its better than an open filter cold air intake because it won't get dirty as quick and it wont pull in engine bay heat. Cutting the cats out would help especially if they're clogged. Just advanced the timing on mine a little and that made a very big difference. I got the link from ymeski56 on this forum, best thing ive done to the truck since ive had it, and fairly inexpensive.

Pretty amazing, inexpensive Performance Mod, fun too! This link (with parts included) would be a great "Stocking stuffer"! I'm glad to hear it worked well for you!
Best $140 bucks I've spent on my truck! It's comforting to drive around w/ a bullet proof ingnition system (figure of speech, especially in L.A.!). By all means, spread the word!

 

It is a 90 efi, i was wondering how hard it would be to remove the air pump and most of the un-necessary stuff like that? Plugs, wires, cap and rotor are done, currently cleaning out and resealing the water pump...task and a half taking apart the front of the motor in -30 weather. Thanks for the suggestions guys,

removing the air pump isnt hard, but it isnt going to change much. I've heard half to one horsepower difference. Mine is disconnected and the lines are plugged but the pump itself is still hooked up. Some people have turned the idea of running the pump to the intake as a makeshift low psi turbo. I dont know how much it would help though.

 

Now that's interesting. I'm not sure a MAP sensor engine would tolerate that, well. it would probably then to run lean.

 

Yea I dont know if it would work or not. If I get real bored one day maybe I'll try it. Another thing to get a little more power would be an electric fan.

 

Smog pumps from trucks work great on lawn mowers as a turbo...but be sure to lean out the mixture so you don't pop headgaskets on em.....the smog pump doesn't steal any power away from your engine through parasitic drive so you're good to go with that....my lines are disconnected so it just pumps air in then right on back out.

 

I still have my pump hooked up...I gained more by adding an MSD box (and timing bump) and adding an Electric fan in place of the clutch fan...

it takes much less effort and pedal to run 85mph down the highway now...
