Turbochargers

[Pimpalero03]

it would be tight havin a turbo'd 3400 but not sure its worth all that money and voiding of warrenty.

i gotta feeling htere are gonna be alot of cooked trannies once people start installin this monster.

be carful dude...... turkey ur doin the smart thing and doin ur tranny at the same time. good idea

I have to agree the tranny is a must. I think you would be ok for a bit if you kept the #s down to around 5-6 but who wants to go on a guess. If the trannys from domestic performance end up being high quality that would be for sure the route to go.

Are you going to just install a whole new stock tranny or rebuild yours jturkey?

sweet......yeah, i figure i want my car to look good first, so ill get all the body and stuff done for Power Tour, and even though the turbo kit will cost more after the intro period, i figure as with any product, all the kinks will be ironed out

stealth....i will be going with Domestic Performance for the trans, im not sure if Ty will have cores available for the alero/se, but more then likely he should, otherwise i have a core trans in the garage for this purpose, there is some more in fo on the trans here http://www.grandamgt.com/forum/showthread....20&pagenumber=1

Why bother getting a tranny made for the alero...might as well get the gt tranny from domestic performance and just get a chip from dhp. I was under the impression he didnt need cores.

Ok, so that thread at GAGT.com was old so update me.

Are you getting it for around $3,700 or $2,500 like Domestic Performance is offering. Is it still a custom kit or can you buy the grand am one now for the alero.

Plus the torque converter is not included, its extra and is another $450. At least for the ga at Domestic P.

I'd be interested in this probably around fall after the turbo is in and i have more time to save. I would definitely like to hit 300 but it all takes money and i need time to get that.

Keep me updated please. This is something i'd be interested in later on.

everyone says this but how many have actually busted a trans???
homegrown blew his engine and his trans is still ok.
key is this
trans cooler, a tune or auto trans to firm things up, and never change the fluid no matter what.
the only one I knwo of to destroy this trans changed the fliud and thats when it started to slip.
mine has seen 10psi of boost, 75 shot, 100 shot, 50hp in bolt ons and still shifts great with almost 70k on it.
this trans needs more credit than people give it.
you guys act like just over stock power and your screwed.
considering what my trans has been through, its pretty strong

screw the warranty! :P

Good thats re-assuring to hear. Because i plan on turning it up to 10 lbs. And with the alki kit, it should be able to handle it no problem.

alerosince99.......thats what i mean...i have a gagt trans in the garage waiting for whatever, but if they can succesfully change toms gears to 3.69 and spoof the puter perfect, then it doesnt matter what trans i use

john...tom says his is slippin here and there, and his hasnt seen the extended abuse yours has,

stealth....the reason for all the price ranges , and the torque converter seperate is because some people have interest in only a few things, like the torque converterr, or input shaft and clutch packs, etc.

Your trannies should be ok, I bet they hold up pretty well to somewhere close to 300HP/300ft-lbs... just don't go flooring out around corners to make sure the diff. doesnt grenade (definately the weakest point in the tranny) and you should be good....

prove me wrong then john!!

70,000 miles 75 shot, sc, sc +35 shot, 75shot, 100 shot isint enough proof?
my car has seen some type of forced induction 75% of its natural life
mike in denver ran 15 psi on his alero. what broke? the pistons
homegrown ran his car hard too, what gave? somthing in the engine
what more do ya need man?
show me the numorus numbers of people that have blown it then.

not only that but nitrous is much harder on your trans than turbo or sc.
I'm making .6 hp shy of 300 ft/lbs at the wheels on a 75 shot
seriously yes the trans does need help. but it will hold up to more than people give it credit for.
I'm honestly more worried about my stock engine parts than my trans

The 4T45E is a stout transmission, John is right. I have seen some things hooked to this transmission that would really change your way of thinking on it. Currently the weekest link is the direct clutch assembly, not the diff.

Just to get a consenus on this.

You can get the turbo first and the tranny will be fine 250-300whp. If you plan on consistently being at or over 300whp then we should be looking to upgrade the tranny and engine internals? By engine internals do you mean forged pistons and rods or is it in regards to the valve train and springs? In my case I have alot of things being changed on the engine already and might as well upgrade the rest if it something Ill be needing to do in the future.

I'd suggest a good engine balancing rather than the tranny. The tranny will take more abuse, but once you start putting more pressure on the engine, it's crucial to ensure it's in balance and that you have parts that can stand up to the additional stress.

[jturkey69]

well as far as engine internals go.....
1st the pistons...for the turbo you should be runnin a deeper dish..cr should be at 8.5:1...this is the best for the turbo,
2nd...rods...go to a better set like forged h-beams, i forget who all makes them, but i know scat does too
3rd....crank....even though this should be the weakest point because of the split throw journals, the powdered metal rods are goona give before the crank does, only thing id do for the crank is cryo treat it. it doesnt really pay to have the edges knifed, and filled with mallory metal..too expensive
4th...valvetrain...pushrods, rockers, valves, and screw in studs

granted all these things above are for going above 12psi constantly, i think out of all these i would most want new pistons to lower the cr, which keeps some stress off the rods

I had been planning to order new rods and pistons. Having never order anything like this before what info do you think they will be looking from me. Ie engine type and what compression or will they want more than that?
