how can i get more power from my 93 stock sc400 without spending a lot of money. i don't need any turbo or supercharger. need a cheaper way to get more power thanks guys

 

Start with bfi then then a cat back exhaust with x pipe and remove a pair of your mufflers two is plenty or get rid of will of them and replace with high flow if sound isn't a issue and don't go too big on exhaust a1/2 bigger or stick size and a smoother path better bends than factory. Last but not least a set of headers and a tune. All together just give around 40-50 go to the wHeels

 

there isn't to much you can do without boosting...
besides the normal basic upgrades. however 50hp to the wheels, I highly doubt that. maybe an extra 20

 

put a cam, exhaust and headers in and see if anything happens. i swear no ones tried it and posted about it on the internet. while you're at it make a better intake manifold! this little v8 has to have something it can gain. if only i could justify with proof that a good tune and a proper street cam can make significant gains i'd opt to buy them.

damn american v8's and their available power! i envy you!!!

 

thanks guys i will try exhaust first dont want to get too crazy with blower and all that but i love the car thanks

 

A BFI intake is the cheapest and quickest way to get power.
a good exhaust follows: have the factory midpipe replaced with dual's and an x pipe.

then the more expensive things that add power: headers, a piggyback to lean out the fuel trim, and a manual swap (more power to the wheels and more fun to drive)
