I want to add horse power to my car. How much do you think it will cost?

Question

I have a Scion TC which has about 161 horsepower. I want to make it to about 200-250. How would i do it and how much would you think it would cost? And also by adding more horsepower does it damage the car?

Thanks for the help

Answer 1

OK LOOK YOU HAVE TO GIVE US A BUDGET

BEST WAY IS TO ADD A TURBO

BUT YOU have TO CHANGE YOUR CLUTCH CHANGE YOUR TRANNY AND CHANGE URE AXLES EXHAUST AND INTAKE MANIFOLDS



AND IF YOU WANT YOUR CAR TO LAST AS LONG AS THE STOCK POWER YOU WILL HAVE TO CHANGE INTERNALS PISTONS CRANK CON RODS BLOCK


THE BEST AND CHEAPEST WAY IS TO GET A LOW RESTRICTION AIR FILTER FROM K AND N AND THAT WILL ADD AROUND 60 HP DEPENDING ON YOUR ENGINE AND THE FILTER BUT IT WILL ADD ATLEAST 50HP

Answer 2

take the stock air box out of your car, pick up a cold air intake replacement filter from autozone and just rig it up on the end of the stock intake tube. i did that on a 2001 intrepid 3.2 V-6, i dropped about half a second on 0-60 and A LOT more low-end torque. next thing is to open up your exhaust. however you want to do that, dual exhaust would be best for anything bigger than a V-6, if you're low on cash just replace the muffler for a glass pack or a racing muffler, dont get anything more than a 2 baffle muffler. change to ngk spark plugs and if you have the money and your car supports it get an MSD ignition. next thing would probably be headers, then port and polish the heads, of course that can get pretty expensive. just stick to the small stuff. the main thing to look at when you try and figure out how fast a car will go is the power to weight ratio. take the weight of the car divided by the horsepower, you should be able to find it all online. once you understand that, then the cheapest way to make any car faster is to take out unnecessary items. make sure your tires are properly inflated, even a couple pounds over wont hurt them, but dont go too far. i had 35 psi in mine and they were supposed to be 32 i think, so not a big difference. Good Luck!! dont use nitrous unless its an automatic! if you miss a shift, you'll blow your engine to pieces! octane booster isnt worth the cost. and whatever that guy is talking about useing a propane tank, hahaha, not a good idea! its best to build the engine to handle power before you go pumping more fuel or gasses into it.

Answer 3

Hey!
I am also in the market for adding HP to my car.
I dont know what you have done already but if you get an after market header, exhaust system and a cold air intake your looking at atleast a 20 to 30 HP gain maybe more maybe less.
The price on that stuff depends on the brands you buy, the quality things like that.


*Edit*
The person that answered below me has no idea what they are talking about. Adding any kind of air filter cant add more than 15 HP at most. Do some research.

Answer 4

I think you would have to change the engine, it would do no actual damage to the car if it is the right kind (like Ford motors go in Fords ect). The cost is where it can get tricky, especially if the place you go to have any automotive work done knows you don't have a clue, be very careful and do research before making an investment like that.

Answer 5

Turbo is the only way to be reliable and worth while. Their are several kits on the market and should net you a solid 50-60 rwhp.

Answer 6

just go buy a chevy LS-2 350 V8 and put it in that scion, it will be a lot cheaper than doing it the way you want to and will run 400% better.

Answer 7

I would say to change the horsepower that much a few thousand should cover it.

Answer 8

I think TRD makes a supercharger for it. Not sure what the price is though.

Answer 9

Depends on what if anything you have done so far, and how much your willing to spend.

Answer 10

bolt on , couple of thousand
engine mods, couple of thousand
bigger engine, couple of thousand
