Ok i have a 1991 i6 300, and it runs pretty good, but i want a little more power, smoother engine performance, and higher mpgs. WHat all will hollowing out cats do? I want to do e-fans but its expensive, what other cars have e fans that will fit? Will seafoam and synthetic fluids increase these? Please let me know other ideas. I also thought of a timing bump, how much will that cost? Thanks in advance

Cats really nothing unless they are clogged, bump timing a couple of degrees, e-fan about $120. for fan\temp control, synthetics will find all leaks, I use Havoline 10-40 and still get about 6000 out of it, you might get a little increase plus a little mileage, the best thing to do is get a good exhaust.

Ok well i decided to lose the cats, go straight pipe to stock muffler for now till i get $$$ then get like a flowmaster or something similiar. Then how much will a timing bump cost at like a shop? Is it just bumping up the degree or do i have to buy new electric parts?

shouldnt cost more than 20 buck,,u can buy new coil, wires,cap,button and plugs but u dont have to
you will get better spark if u do depends on how long its been since u had an oil change

For e-fans u can get some at ur local wreking yard, the one from Taurus work great thats what i have on my truck. i have some pics here u can check them .

Which is better? I have a donor Taurus with fans I could take off of but I'm uncertain abou the install? Which adds more power and mpg?

HaulnAss all deppend on condition of ur engine. but i think u can gain more horse power with pulleys than e-fan , but u can gain some more mpg. from e- fan too. but have to be carefull with under drive pulleys. ur might have some problems with charging

MSD box if you can afford one and an High Output Coil...that helps too...

how much would an msd box and high output coil be? I just recently had new wires caps and plugs put in, when it gets time to change oil i am goimg to seafoam it before i change it.

if u get high out put coil u have to get the rotor & cap with brss terminal. the last longer whit high out put coils.
