Custom Turbo

[GAguy]

How hard is it gonna be im thinking of getting two turbos off of ebay and running about 13-16 lbs of boost T# turbos how hard is it gonna be i have a 3300 v6 so i was thinking running one on each side of the engine

[Faylix]

Well now you've got yourself a couple problems I do believe.

I'm not TOTALLY sure, but, are you sure you've got the 3300? Maybe you've got the 3400? Or maybe the 3100?

If you put twin turbos on your car, I'd drive over to your house and congratulate you.

[GAguy]

yes im sure its a 3300 its a 93 GA that is why it was used from 92-93 GA and why do you think it would be hard to get twin turbos

[Faylix]

How much $$$ you got?

[GAguy]

well i plan on doin all the work myself and i can get two t3 turbos off of ebay for 400$ so i got enugh i think

[GrandAmSC/T]

LOL hate to break the news to you but its going to cost ALOT more than 800 bucks for the two turbos. You gotta get intercooler, blow off valves, turbo timer, all kinda cool stuff not to mention rebuilding parts of your engine or your engine goes kaboom. And if you dont have extensive knowledge of an engine and turbo set-ups you wont be able to install it yourself. I dont even know anything about turbos but i know theres alot more to a turbo set up than just the turbo. just fyi.

[GAguy]

no i can get both turbos for 400 and i can get dealer discounts on other stuff cuz i gots connections :) and i have some friends that know a ton about turbos

[GrandAmSC/T]

sweet, well if you ever get that job accomplished then that would deserve two :thumbs: up from the grand am community. that would definately be kickass and something that nobody has done before!

[jeremy96gase]

I dont think the 3300 was build strudy enough to handle 13-16lbs of boost.
Not to mention your three speed auto would Fry up real nice with that much TQ.

Have fun trying though

A turbo involves ALOT of work and time.
There is also the fuel management you have to worry about and many many other varibiles and another thing even if you do this start with one at a time you don't need two. One t3 will be plenty!

[GAguy]

well like i said i have connections and i can get stuff cheap and i can always change stuff liek getting rid of that 3 speed and forged internals and i really dont car if its single or twin i just want more power :)

13-16lbs will certainly not work. You will blow the bottomend if not the top first... A lot of work is needed as you know. But I would start with one T3, and run the boost a 5psi, stepping up to 8psi MAX on the stock internals. You will see big problems for the tranny and you will likely toast that in short time depending on mileage.

If you gots the conections then you may be set... but you are still looking at a few grand.

T3 = $400 ... What else???
Forged Rods and Crank ... 1,$$$
FMU ... 5$$
I/C ... 1,$$$
Reinforced Slushbox/Stick ... 1,$$$

*Can't cheap it on all the right parts, and you will need to pay for a unique tranny reinforcement... But it would be awesome to have done.;)

JOUT

well i got a friend that has a 98 GA with the 3100 and he does treanny work all the time and he said he can bulit proof a 4 speed outta the 3100 GA and we will make it bolt up :) but yea i think ill start with one T3 but then well see i wanna be able to make 11 seconds

[homegrown]

have fun making the headers:)

[Pacman]

my .02 cents are gonna be going into the space available. i dont think that the 3300 will have enough space to fit a twin turbo set-up. not only do you have to worry about the turbo timer, boost controller, bov, headers, wastegate, etc. but tubing is going to be another part of the set-up. you gotta go look around and see what is available. i was talking to a local shop that have done 2.4L custom turbo set-ups. they say that the piping can also get pricey as well. i dont think all that tubing will fit unless you fit a really clever way to postion them around the engine. maybe run no hood? yet, i do not doubt you at all. i believe anything is possible. good luck.

[GAguy]

well i am just looking for more power ill start with one and then maybe another with some edjucated reasioning

[jonwepa]

where are you getting the money? according to your profile you r 15

[GAguy]

ive been saving money forever and i have a decent job and no other expensise and i do pay my own insurance and i purchased the car myself and i pay for gas and any repairs

[Faylix]

Hey I got an idea? If you want a faster car, why not get rid of your Grand Am and buy something more suitable for a twin turbo setup?

[GAguy]

because i love to see peoples faces when my car goes flying by and i tell em its a Grand Am and they are like oh **** no i got beat by a Grand Am and plus it will be a one of a kind show me a 93 GA with a Turbo v6

yes but you have to remeber that some of the strongest trannys are 2 and 3 speeds

[Doug]

Your probably looking at a grand if you have a shop make the headers alone. You will have to find someone to make custom flanges too. Your engine will not take 16psi stock from one turbo let alone 2. The fuel system will have to be massive and at that psi, most likely stand-alone. You fill need forged internals. Does anybody make forged internals for the 3300. I'd say go for it if you have the money. :) If you go ahead with it you better be ready for a long haul. Trust me ;)

yes GAguy is right. The 3sd in the cavs are stonger then our trannies. they are made for some trucks too so they have to be able to take the extra punishment.

[bszopi]

The 3300 is a 90º V6, so there are more aftermarket parts available for it than our motors. But you can't expect to find listings for the engine. You'd need to figure out all the internal specs/dimensions and go from there.

Remember, 90º V6 are just SBCs with 2 cylinders chopped off.

[GAguy]

yes i know that but they would be too big since most parts would be for a 3.8 and if i got a aftermarket cam for a 3.8 that would be too much lift for my car

Thank you.. finally someone that sees the sunlight.




2 turbos... one would be hard enough.

So i dont go into a long talk again about all of this..... You can read it here...

http://www.grandamgt.com/forum/showthread.php?s=&threadid=6070 You cant miss my huge post

Bottom line you would need like 15K at least to twin turbo a 3300 GA.

Custom exhaust work
Fuel work (injectors, pump and management)
Lots of luck to spool those things at a level to even MAKE good power and not have it come at 4k and leave at 5,500

15k and you could make it happen.
