Hey everyone, im pretty new here and i just started getting into cars, just
looking for a little bit of advice.
I have a 1998 Pontiac Sunfire GT (the exact same thing as a Chevy Cavalier)
- 4 cylinder, 2.4L, manual transmission, 5 speed
It comes stock with 150 HP and 155 ft. of torque.
Im looking to get it up to around 170 to 180 HP and torque, but without loosing MPG.
My plan is to get:
- Injen Cold Air Intake
- Open End Mufflers
- Aftermarket Headers
- and something called a new pulley system? (someone told me to get this)
The mufflers, headers, and intake is supposed to give me more HP/torque, and improve MPG slighty (so i hear).
Does anyone know if all these parts sound right? What else would you recommend?
Thanks to anyone who helps! :mrgreen:
Make that a short ram not cold air intake, no company makes Cold Air Intakes for the 1998 2.4L sunfires or cavaliers :(
First off, your car is an inline 4 cylinder, so I'm guessing you only need
one header. Also, if an open end muffler is what I think it is (a cutout)
then your car is going to sound loud and crappy.
I'm guessing the new pulley system is an overdrive pulley. When your engine is runnig there is a pulley on it to power all of your accessories. This pulley takes less power from your engine, but also delivers less power to your accessories.
I don't know if anyone does tuning of that particular car, but that might be something to look in to. It might seem crazy to spend $500 on a dyno tune for a Sunfire, but it'll be cheaper than buying all of the other parts you listed and will probably yield similar gains in hp, and I'm betting you'll actually gain MPG.
Open end mufflers will just make noise, they do nothing for performance. pulley system I am guessing an underdrive pulley...youll get maybe 10 horsepower combined.good luck
What about putting in a Venom 400 chip in?
good idea or bad?
heres the link:
i uno lately ive been hearing that they are pieces of ass
What type of chip do you recommend?
hhahahahaa...... sorry... if you knew his history, you'd realise how funny that was.
but does anyone know a decent HP chip?
there is no chip for the sunfire. only out there that works good is HP tunners. but i got a 2002 2.4 sunfire and im using the gm eaton m45 supercharger small pulley heatwraped header full exhaust cobalt SS injectors ram air hood overdrive pulley and methonal injection kit.
