just a question for all you buffs out there. I was thinking of getting the turbo charger from Garett or alpine for my 2.2l (LS61) with Auto Tranny in it. is it a bad idea to take a Auto and stick a turbo in it? i already get enough crap from my friends about driving a auto and not a shifter. so what do you guys think, is a turbo on a auto a bad idea? Can i get some pros/cons any advice is valued...except the flaming. thanks

 

Well the search button helps a lot. but to answer the question again, you buy a tranny cooler and shouldnt have a problem.

 

I'd think a high powered turbo/auto would have its advantages...no lag between shifts.

p.s., dont let your friends try to tell you auto's are slow, etc. etc., it just shows what they really know about cars.

 

well their are some things you gotta know about autos and why some people rip on them. well 1 you lose power to the wheels. and you only have 4 gears. which isnt bad by the way just stateing that. and well adding a turbo isnt bad at all. go for it man and do it. u'll be smokeing a lot more cars now. and who says autos are bad all the time. u dont worry about ur launches as much and run solid ET times. autos FTW. but unless you want a manual stay auto and turbo it.


btw id invest into selling that GMPP exhaust and getting a 3.0inch Hahn racecraft Catback. turbos like 3.0 best ive heard.

 

For about 300 or less you can get a local muffler shop to put in a 3inch exhaust. Buy the 3inch high-flow cat and muffler(i prefer Magnaflow for both), and they will get you Mandral bent piping and install it. Much cheaper then buying an exhaust kit from someone.

 

yeah, i've searched a lot and found a lot, too. I Just thought i could get a little more info, thanks! btw, it seems you've got the Alpine in your car, did you do most of the work yourself or did you have it installed by professionals? its work i wouldn't mind doing but i'd rather have a pro do it since they are more of a guarantee and better equipped.

@HotSauce

yeah, i know...friends can be so cruel... . i actually get more "talk" when i tell them what i drive. lol, it'll be funny when my LS is smoking those Civics and tC's after i get my turbo.

BTW, you guys think a stock LS auto can out-drag a stock tC?

thanks for the tip, i'll go check this out, i know a few good shops already but didn't think about it.

 

I dont know the EXACT #'s, but from what I READ..stock tC's are slow..lol

 

very true there is one car that disproves that myth hands down... buick grandnational

 

I like both autos and manuals, but auto is just so much more...convinient, lol. thanks, for the advice, i am definetly going to be looking into the turbo kits for my LS more carefully now! i'll check out the new exhaust system, too!

 

I would get an external tranny cooler, with the extra power, the tranny will create more heat. The auto can handle more power than the stick WITH some mods. I like both, but autos do have some great advantages over stick that many people dont know about. If you plan on pushing the car past the 250whp mark, I would recondmend upgrading your torque converter and a shift kit(I believe some of our supporting vendors sell them) I am not sure what the gm fwd trannys can handle but that is what I would do.

 

May want to pick up the B&M shift Kit that HackAbuse tested.

 

I'm gonna give that one six more months to see if his tranny falls out from under his car. He IS testing this product.

But on the plus side , if it does, you can simply sneak that shift kit back off and say you don't know what happened.

 

auto should be fine, i am planning on putting down at least 250 if not 270 i might push it

 

the only thing with the 2.2 there really is a tune for it. if u cud tune the auto tranny, it wud b a beast, plus turbo. it wud def move

 

My car was the test car for alpine. The tune they made came from my car. So yes it was professionally installed/tuned. lol.

 

well, even better, lol.

Scion tC '07
HORSEPOWER 161 hp @ 6,000 rpm
TORQUE 162 lb.-ft. @ 4,000 rpm

Cobalt LS
148 horsepower and 152 lb.-ft.

--> from the tC and chevy pages, lol, i dunno...looks like it can put up a fight against a stock ls. hopefully the rumor is true and they are really slow!, i gotta ask a friend to gun it so i can see what its got.

 

an auto ls will lose to a manual tc by a car and a half
auto ls vs a auto tc is a coin toss most likely the tc will come out the victor... by a bumper
a manual ls will lose to a manual tc by half a car
a manual ls will beat an auto tc by a car

 

well the tune for my car was a lil to rich, kept blowing out black smoke, idk what about my car made it so diff from urs, they spent an hour or two to get mine close in all ranges of the rpms. and at WOT my cel would flash at me and then go off any ideas why this would happen?

 

Dont waste your money its not worth it. but if you want to blow some money i can give it to me my hands out

 

I believe you can tune the auto trannys with HP tuners, I am pretty sure I read that somewhere, so I would look into it. A shift kit not only improves performance but will help make your tranny last longer, It will have firmer/harder shifts though. But make sure you get a tranny cooler, they are cheap and easy to install and will make a big improvement in reliablity.

??? Dont waste his money on what? Turboing an auto?

I like both auto and stick but a well built auto will outperform and handle more power than a stick would.

 

thats an ass load of money to dump into doing that. its not a strip car. dont get me wrong moding your car is great but do somthing that makes sence. that kit and tweeking you tranny is going to cost you and besides that tranny is not built for that type of power. but hell it's just my oppin. and that is what the thred asks for.

 

says who? lol

every race turns out differently, different drivers, different conditions, different factors. I can race someone 40 different times and get 40 different outcomes.

 

ok, i'll tackle all these in one post.


3" is too big, even for a turboed 2.2

see above

pretty much a drivers race manual vs. manual.

the B&M has been running on cavaliers for thousands and thousands of miles no problem, same tranny

what makes it not worth it?

1) doestn' mean he can't make it into one.

2) yes it is... stock tranny can hold MUCH more power than the engine can put out... it can hold almost double the stock power no problem... it's pretty strong

 

I dont believe 3inch is going to be too big because im looking at a bigger picture. Im gonna be putting out A LOT more power then what i am now in about a month. Ill be at about 15psi, so 3inch will be perfect...

 

i'll stick with my 2.5 inch and hope it works well, guys at corsa said theyve used it to 600hp
