Which Turbo Should I Get [merged] What Turbo

[Ludachris]

Which turbo will be sufficient for consistent 11 second times? I've recently decided on a big 16g, but will that be big enough to run 11s with supporting mods and decent tuning? Remember, this is for a budget street car, so any one purchase over $1k is tough. A big 16g will run about $700-900, which is about $300-400 less than the larger alternatives.

Of course, I'll need lots of practice to run these times, but, I just want to make sure that it's possible before the money is spent.

What would you guys suggest for a nice comparable AGP turbo?

Only if you get the 3" o2 housing. Their 2.5" is a 100% bolt on. On the AGP side they have a 52/lb full garrett setup. Which i *believe* utilizes the same wheels in a Garrett TH and that kick ass SFP mani

sorry for being a post whore but its urgent!
will the regular 16G bolt up or the evo III big 16G?

 

[ckozlgod]

both

 

[L2RTSiAWD]

Neither on a 2G they will need an install kit. A big28 will bolt up using all stock 2G parts.

 

[95Eclipsers]

ok which one of u guys is right, and were can i get the instal kit

 

[ECLIPSE4x4]

if your asking to bolt up to the manifold ... YES, will you be able to mount the stock intercooler piping... NO, NOT without an "J" pipe or if you have the compressor housing rotated (there is alittle more involved then just rotaing it).

 

[95Eclipsers]

I need a new turbo for my eclipse anyone got a sight were i can buy one i dont care if its 14b, or t-25, ust wanna get the car on the road for now, anyoen got a web site wanna keep it around 400 and want to have everything i need to come with it

 

[L2RTSiAWD]

If you need to get it on the road buy another t-25 you can get them for 80-150.

 

[ECLIPSE4x4]

WOW, from a question to a WTB add....

 

[newtoturbo]

Okay. I have just determined that my turbo is definitely bad, due to the oil in the intake and in the turbo inlet. I want to upgrade to 16g but I do not know if I need new injectors, computer? and or anything else. My car is completely stock and I am new to turbo and DSM's. I have an automatic transmission so I know that I have a 13g turbo, right?? Will a 14b turbo be better and will I have to do any mods if I go that direction. Any info would be greatly appreciated. If you have a turbo or boost gauge for sale I am also interseted.

 

[TSi92]

I know some will argue with me but you don't really need 550's with a small 16G. A 255 will be enough.

 

[LightningGSX]

Oil in the intake and turbo inlet does not neccessarily mean the turbo is bad.

heck, you could even go with a 190.

A small 16g doesnt flow much more than a 14b, so there ought to be no hoopla about it.

 

[project94tsi]

did you know that the crankcase breather is attached to your intake and is known for spitting oil in you intake system, i would check the turbo for shaftplay, if there is no shaftplay and your exhaust isnt smoking or anything then i highly doubt that your turbo is toast. You cant just assume something is broken without investigating a little.

Shh!! He needs an excuse to upgrade!

Seriously, though project94 already hit it. If you think your turbo is blown only because of oil in the inlet and intake you need to realize that unless you attached a catchcan or have the valvecover breather hose not running into your intake, that this is normal.

If your still feeling boost, not burning any large amounts of oil, and (and you need to go do this now) the shaft inside the compressor housing does not move very much either side to side or in and out, then your turbo is fine.

But since you have a 13g, upgrade anyway to something like a small 16g. Drop a walbro 190 fuel pump in, rewire it as per www.vfaq.com, and keep the boost around 15 lbs and you should be golden.

*edit, GET A BOOST GAUGE. And a manual boost controller.

christ, this HAS been asked a 1000 times before, mabye a million since those "Movies" came out.

PLus, all the turbos that you listed in the "Poll" have been in the 11's, some on pump gas, some on race gas making as much boost as it can (T-28, ).

The FACT of the matter is....

What kind of shape is your Car/engine/tranny in? cause if its less than perfect, Stop right there, as 11's is a pipe dream

How good of a driver are you?
And I don't mean, "Can you bang the piss out of your tranny? Cause half the battle of makin daily driven 11' second passes, is keeping the driveline together.

Third in line would be, Do you have any supporting mods?
How about a datalogger?
No? you had better get one even before your "Exhaust gets there"

reason why some of us DSMers get so heated at a question such as "What turbo will get me 11's"? is because its not easy. Newbys think because an 11 second pass is highly attainable from an AWD DSM, it isn;t likely w/o years of prep, breaking shit, and finding the right part combination.

At any rate, do your homework.

Good luck.

Thanks for all the input. My car blows blue smoke, oil, and fouls out my plugs so bad that I can not go above 2500 rpms. I cleaned the plugs and it ran fine for about a minute, not enough time to diagnos anything though. I will definitely check the turbos shaft play before I do anything. Can a 14b turbo produce 15 psi with out me changing my fuel pump. I just put in a new stock pump and do not want to buy another one. I also thought that it was weird that my car runs okay up to 2500 rpms but then starts to misfire. My plugs were pure black. Could this be because my turbo is not producing enough boost. I have a stock boost gauge and it shows my boost jumping all the way up to 14 psi when I give it gas. I now this gauge is a joke but it is very weird.

 

[Todd95TSi]

I think the auto 1g also came with smaller injectors (390?).
If this is correct you may want to upgrade to AT LEAST stock 450s or 550s. Used 450s can be purchased cheap from most tuners.

 

[SrKegler]

From the symptoms you described, I would first do a compression test. Sounds to me like your rings are shot.

 

[KPWSerpiente]

A compression, and if you get bad results then a leak down test.

But if you are having problems at 2,500 rpm, and that sounds to me about when a 13g will spool, I'd jump all over checking it for shaft play.

And here I am. Ready to argue!
450's are ok if you're running mild boost levels (14-15psi), but if you really want to have fun... and you will... get 550's and a Walbro 190!

You can get any turbo you want as long as you don't over boost. I think you will be fine with the stock injectors as long as you have a SAFC. But 550's and a 255 would be alot better.

 

[EvolvingGST]

all us DSMers need huge turbos....

Its was the 11th commandment:

11. Thou who owns a DSM must get a huge turbo.

See it was the word of god... so You want to go out and buy a green or a frankenstien or a T3/T4 hybrid. j/k


But if you want to upgrade do it right... yeah a small 16g seems like a plan with little modifications needed besides the rewire and maybe a 190 lph pump?

 

[doodie]

450cc injectors work fine on a s16g untill 15psi or so. I wouldn't run over 16psi with stock injectors without fuel mods. Don't risk blowing up the motor when you can spend a few hundred and have it run a lot quicker and more reliable.

That sounds about right, definately not 450's in an auto.You will need to upgrade the injectors with any turbo upgrade IIRC.You may also need to swap a different injector resistor in there too, but I'm not entirely sure on that one.
