It all depends on what your goals are. What kind of powerband are you looking for, and how much overall power are you looking to make? Are you going to be drag racing/autocrossing? What is your budget like? Doing a single turbo conversion properly is not cheap...

as trweiss said it really depends on what your power goals and what kind of use the car is put through i.e. drag/autocross/circuit/street...but i think an excellent turbo is the gt35r...excellent spool with very decent power capability...

^ Agreed. The GT35R is a very common turbo, and is great for spool and top end power. Also, the 500R that I'm running is a very good turbo for useable power. With a moderate street port, there is very minimal lag.

well actually im not looking for that much power right now bc im staying with the stock ecu. i was just wondering if anyone have gone from the twins just to a single. and how big would i be able to go? all i have right now is a street port something small. im using it as a daily driver

You absolutely do NOT want to be going single turbo with the factory ECU. I can tell you that much! Not to mention the fact that you're (most likely) on stock injectors...

If you are using it for a DD, I'd suggest sticking with the factory twins. If you're looking for a little extra power, why not do intakes, exhaust, and a PowerFC, then retune? To do it correctly you'd have to port the wastegate so you don't get any boost creep, but you could also raise the boost slightly if you bought a boost controller (to around 12-13 psi, IIRC) while staying with your current injectors. Needless to say you'd have to get a tune though. I made 330RWHP with a PowerFC, Greddy airinx intakes, XS Power SMIC, Pettit MP, Greddy SP1 exhaust, and a tune from Dave @ KDR with boost levels @ 14psi. Here's a vid of the run => http://www.youtube.com/watch?v=uSbvqgclJ_o

Going single is quite the project, though. It's not something that you can just bolt on over a weekend. :P It takes time to get it all right.

but i can just find a turbo that can toss me the same amout of air like the twins do. and the same injectors will work.

how much is one of those power fc running?

But what would be the point of going through all the trouble of installing a single turbo, then making the power that you could easily make with the twins? It just wouldn't make sense....And you're not going to beat the response of the factory twin turbo's. A single WILL lag more, even if only slightly.

Last I checked, the PowerFC will run you around 800 dollars with the commander, but I have not priced them out in quite a while... I'm just trying to save you a lot of time, money, and frustration, that's all. You really have no need to go single, since you don't have any lofty power goals. I suppose it all boils down to what YOU want out of the car. First, you really should define that. What are you looking for it to do? What kind of power are you looking to put down? Etc, etc...

But at first glace, it really sounds like a lightly modded twin turbo setup would suit you perfectly. Not to mention the fact that you should have a bit of experience with these cars (IMHO) before going single...

Sounds like you need to do a little more research. gt35r and t04s are the most common turbos used. If you arent trying to get much power out of your set up i would recommend the bnr stage 3 turbos. Still twins but have more power potential. Upgrading you fuel injectors is goint to be a must (secondary's at least). These cars lean out quick.

Also i dont think you're gonna be able to run a factory ecu with your car being single turbo. A power fc can run you up to 1100 dollars, and you would still need to get it tuned. Regardless, its still one of the best upgrades you can do. If you're going to be tearing into your car you might as well replace what you can with the parts you need to achieve your power goal

TRWeiss1

^ Some good advice. I'd also recommend upgrading the fuel system ASAP. They do lean out quick, and you don't want to go detonating. You'll lose your motor before you know what happened. Overbuild it, if at all possible. At the very least get some larger secondaries, as stated. I run an RP fuel pump, Aeromotive AFPR, Kgparts rail, 850 primaries, 1600 secondaries, and SS braided lines.

armytim2002

Agreed. These cars arent meant to stay stock if you want to increase your power. Stick with the stock and go for the minor stuff like TRWeiss said before. Then slowly start to upgrade your major parts. I also think that the 35R is the one you want if your not looking to get crazy numbers. Just remember the higher then HP the more your wallets going to be mad at you and the more your going to need to replace.

Also if you do start going through compnent changes please dont forget cooling. These cars will overheat on you just sitting at the red light if your not careful. New temp gauges, thermostat, oil coolers, radiator, etc.

TRWeiss1

iTrader: (20)

^ Excellent point. I run the Fluidyne radiator and 180 degree t-stat...And with my FMIC I can still see 90+ deg C temps on my PowerFC on a warmer day. And if I'm running the A/C, forget about it...Even WITH the aftermarket cooling mods I'll be up around 100+ deg C! I also have a Defi water temp gauge, and keep a sharp eye on that in conjunction with the coolant temp on the PowerFC.

i just want that bad boy to look nice and clean i will hate to mess with the twins its harder. one is easier and i can just use my boost controller to have low boot bc i dont have much fuel and then later the upgrade will come. and why cant i setup my single turbo with my stock ecu is not like im doing something diff the computer weather is twin or single. and yes i agree with yall on all that but i just dont want to upgrade my fuel now ill waist fuel like crazy. got a heavy foot.

One thing you're not understanding and taking into account is CFM (cubic feet of air per minute). If you install a GT35R and run 15psi it's going to flow significantly more air (higher volume) than 15 psi on the stock twins. That's partly why you can't run it with the stock ECU...Not to mention the fact that your stock fueling system will not be up to the task...Keep in mind that just because your injectors/pump could support 12 psi with the twins does NOT mean they could support 12 psi of say, a GT35R.

Secondly, you're going to hit fuel cut right around ~12 psi with the stock ECU, and it's DEFINITELY not worth it to run a single turbo (like a GT35R) that far out of its efficiency range, IMHO. That's just ludicrous. Why would you go through all that trouble of installing that turbo to run it @ 12 psi or less when your twins are perfectly capable of handing that same task?

And talking about not upgrading injectors because you "have a heavy foot and will waste fuel like crazy"? If you don't you'll be wasting motors like crazy.

No offense meant here at all, but you have a lot, and I mean A LOT, to learn before you go slapping a single turbo on your FD. :P

Listen to him /\. This ain't a game.

And going singal the right way will spend you atleast 8k.
Trust me. I'm way over that number mark and stil got 40% to go .

^ Exactly...You don't even want to know how much I have invested in my single turbo setup, and I'll freely admit that there are many on here running a more sophisticated/higher quality setup than I am. And the sad thing is, it never ends!

I also opted for a ball bearing turbo, and ceramic coated exhaust housing/manifold/DP...You'd be amazed at how expensive the ceramic coating alone was.
