What exactly do you need to make your 2003 Mitsubishi Eclipse Spyder GT as fast as possible and how much it would cost?

Answer 1

This question is kind of ridiculous there are so many combos of parts you could use to make any car fast. The first thing you wanna think about is if you really wanna spend the money to make an eclipse fast because for the same money you could probably go out and buy a faster car. The fastest route to power is always forced induction, whether it be nitrous oxide, turbocharging, or supercharging. With all of these come the probability that you WILL break something if you run too much nitrous or too much boost, therefore supporting mods must be done to the motor to safely reach new horsepower levels. Supporting mods usually include upgrades to the fuel, spark, and exhaust systems, (such as bigger fuel pump(s) coil packs for the ignition and much larger exhaust with less restrictive manifolds mufflers and cats.) Beefing up the motor and transmission with stronger internals will also be required for larger power gains such as carbon fiber synchros and stronger input/output shafts in the trans and forged pistons and connecting rods in the motor. The route to go nitrous, turbo or supercharged is entirely up to preferance (also remember you gotta put that power to the ground as well as stop it, so with power comes larger tires and brakes). Only you know what you want from your car. Not to be pessimistic but the motor in your car might be able to take some abuse but your transmission is built to handle the stock 190 some horsepower/torque of your motor so you will almost definatly break something if you do any kind of forced induction, also assuming your car has over 50k miles for it being a 2003 and being a drop top which makes it have more of a leisurely feel your best bet is to not drop a lot of money into it and start breaking things just throw on a new exhaust system, cold air intake, maybe even go as big as a larger fuel pump and injectors, as I said what you wanna do is entirely up to you. I hope this was somewhat useful and I'm sorry for the novel but this is such a vague question. If I didn't answer it I don't believe you would've got an answer or if you did it would probably be as vague as the question itself. To sum this up for you and give you a ballpark price range, I have a 2001 Mustang GT, lets say I wanted to supercharge it. 2.1l twin screw supercharger kit from Kenne Bell - $5,000, then I would have to build my transmission because it can't handle the added torque from the supercharger - $2000+ and also if I wanted to safely run more then the 9 psi the kenne bell system comes set to, I would have to get forged internals for my motor $2000+ so as you can see this is not very cheap. However after all these things being done to the car I would still only be running about 475 horsepower to the wheel at around 14 psi and be running maybe mid to low 12's in the quarter mile if I went and bought myself some drag radials and beefed up the rear end with new control arms, shocks, gears, axles, driveshaft/u-joint as well as the clutch, flywheel, and pressure plate. If I didn't do these mods I would either burn out my clutch or snap my rear end if I launched hard. All this stuff, another $1500. Think before you mod, think long and hard.
