Hey guys i have a 2.4l automatic cobalt. I have been told that u dont turbo an auto u always supercharge. But here i have seen some that are turboed too. I am looking for a decent gain in horsepower. Also with this added what would i be running against. or like similar too?
thanks a lot sam

help i need suggestions

 

It doesn't matter what type of transmission you have, as long as it can take the tq you throw at it.

 

I have the 2.4l automatic.. I am llookin to buy a supercharger or a turbocharger..I have been told go supercharger because autmatic but i have seen some autos turboed...so what do u guys all think

 

Merged, just one thread please.

 

okay...welll then if i went with a turbo...would the automatic transmission be able to **** right and stuff?

 

ill take it u ment shift, yes the automatic tranny holds up with forced induction alot better then the 5spd one, members have done it and it works..your cooking with gas

 

what would it affect...would the gas milage change

 

i've asked celica cobalt about this (2.4 turbo by hahn) and he hasn't seen much of a change at all in his gas mileage.

 

You are going to have to learn a lot to do this right, no matter which way you go. Watch this: http://www.youtube.com/watch?v=Z3iBKwcQ3Yc I got that from the Gale Banks website and it explains about turbo/superchargers, how they work and the differences between them. Once you watch part one (the link), click on part two to watch it also.
You'll be an expert just from those two videos!!

I'd go turbo because it may be cheaper and you won't lose 20 or so HP just spinning the blower, but many things will affect your final decision. By far the easiest way is to buy a good kit, from a reputable company that has everything single part worked out for you.

Search the forums, there are tons of threads about this!

Good Luck!

 

im superchargin my 2.4 ss....b/c....i love the whiinnne!!!!! and its cheaper...and thats basically it

 

thank you that helped a lot!!!

 

If you are going to turbo or S/C a 2.4L with Variable Valve Timing, you should also replace the LE5 intake and exhaust cams with those from a LNF engine to gain the best performance and to avoid "overlap condensation"!

 

well i have a k&n intake right now

 

keep researching man/ theirs all kinds of threads on forced induction

 

i have very close to stock drivability and MPG. Power is great automatic handles the power like a champ though i have added a tranny cooler.

 

yea... well if i went with the hahn how mch do u think my car will be pushing?...celicacobalt what kind of cars can u run against!!

 

go hahn turbo kit dyno specs say 290hp with turbo kit at stock healthy 8psi that is 120hp gain safely cant beat that im goin 2.4 eco in my 01 cavy im goin hahn kit u cant beat it for $3400 stage 2 u will smoke the ss supercharged

 

well, 2007 mustang GT's are no problem if that means anything, at least when i was at the track they were getting slower times than me.

 

yea okay..would i be able to run a cobalt s/c? cause i have driven one of those soo i kinda know how quick it is

 

^^^ a stock one, sure, no problem

 

dAMN I AM LIKING HOW THIS SOUNDS cause those are quick.. what about a subaru sti?

 

lol that was quite the jump. from a stock SS/SC to an STI lol

it really depends on how much HP you're making and how much of that power is actually making it to the wheels. traction is also an issue. So it could be different for each and every set up but if you're making 290 whp lol then yea you could run with the big boys

 

lol okay man.. thanks.. i needto run with the big boys considering i roll around with a sti. srt-4 and evo mr... lol so yea

how much do u think it will cost for installation and a nice tune. also need to add in a guage cluster pillar and the guages for everything and not just that but also i would be looking to invest in a boost control.. Considering i will be turboing a automatic will you even her the turbo... like would it be worth buying a bllow off valve or nah. Thanks
SC

 

trust me, you WILL hear the turbo in the automatic!

 

like thats not what i mean by hear the turbo.. i mean like with a manuel when u shift.. u hear the noise from the blow off valve... would u hear that with an automatic too?

Soo what exactly are he steps to turboing the 2.4l. like what do i need to do
