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.

There are a lot of things that you could do. I would first look at the upgrade path section here.

Tech Guide: 1G 4G63t Upgrades - DSMtuners

first you need to know your goal!! Drag, street, autocross....etc. then decide what path you want to take. Search the site there are tons of posts here!!

my goal is street, this is going to be a daily driver so im not looking for anything extreme ive basically got the stuff i want to put into it for now but i need a bigger turbo with a bigger flange to adapt to the new header unless i custom fab a new flange but i would just rather bolt on a new turbo that will spool loud give decent boost and not need much for upgrades after bloted on i already have the 3" piping kit for the intercoller a bigger front mount intercooler and the header i plan on probably going with a 3"exhaust also basically all i need is to know what turbo i should get and if im going to need to upgrade other things such as fuel pump ect...

Well I would recommend an Evo3 16g or a Small 16g as far as turbos go.

For mods you will need

Walboro255 OR 190 , Use the 190 if your pretty positive your never going to upgrade your car faster.
I think you need atleast 550cc Injectors to maxx out a 16g.
If your going with the walboro255 You will need an air fuel pressure regulator.
You will need a 16g install kit or make your own version.
And replacing the headstuds and head gasket wouldn't be a bad idea just for safety.
You might want to port your o2 housing and exhaust manifold as well for less boost creep

Oh yea and get a tuning program like dsmlink
After all that your pretty much set

You meant to say Adjustable Fuel Pressure Regulator.

And in my opinion you will max out the 550cc injectors before you will max out the 16G.

Generally a bigger turbo takes longer to spin up to speed, but it delivers more maximum power. The time the turbo takes to spool up is seen by you the driver as lag, or delay time. You may mash the throttle, but your engine wont produce "boost" until the turbo is up to speed. So you have to be careful on getting a "big" turbo. Especially a t3 or t4 flanged turbo. Of course you will need all supporting mods. to tune your car. Good luck with your build, on whatever power path you choose.

 

[gofast63]

16g all the way. That's what I'm running and it spools loud. They are good turbos, also you can sell the header and just use your stock manifold with the 16g. It will make your life a lot more easy, Its not fun when you break a bolt off your manifold.

 

[evil tsi]

if you use a 255lph pump you will need to use an afpr, if your manifold flange is too big, you most likely have a t3 manifold. just port out your manifold and 'o2 housing like stated and that will be plenty. stock ported manifolds have been proven to over 400whp. to max out a 16g you will at least need a set of 850s. do a lot more research and do your maintenance first. then follow the upgrade path.

[widebody1g]

alright, so i will most likely go with the 16g big turbo, i already have the header and intercooler/3"piping kit so now my question is once installed onto a completely stock motor what problems am i most likely to run into and have to change or just right off the bat change such as fuel pump injectors n what not i also am going to look into a boost controler (probably a simple mechanical one) but id like to know what im going to need to upgrade forsure, P.S. thanks for the help so far guys! i have been stressing over these questions and beeing in northern ontario not many people are into this kinda stuff especially playing with talons or turbos in general, thanks alot!

 

[Jon91TSi]

If how loud a turbo sounds during spoolup is seriously a consideration of yours when selecting one, you probably should be driving something else. Your car will probably end up in the scrap yard just like most others.... :endrant:

 

[widebody1g]

jon91tsi, thank you for your display of maturity, if this has no interest to you keep off of this post? im looking for help not someone to put down my build, but again thanks to all those who have given help so far now i have another quick question..would i be able to bolt on a 16g big turbo and have it run fine without upgrading fuel pump and injectors and what not right away? basicaly just leave everything stock and bolt on the turbo and set the boost moderatly?, and also what size "cc" the stock injectors are?

You could bolt in an evo 3 16g which is a really sweet turbo and pretty cheap brand new. But with everything else stock it won't make any more power for you than the stock 1g turbo, which is a 14b if you have a manual tranny.
Have you read about fuel cut yet? You need to read about that - it's the first thing that will happen to you when you raise power from stock. It will scare the crap out of you the first time it happens.
If you install a proper downpipe, cat delete or high flow cat, 3 inch exhaust, and a boost controller, you will easily make enough power to hit fuel cut with the stock turbo (this is all "stage 1" stuff in that upgrade path link given above).
At this point there are 3 things that all run out of legs at about the same hp level. The stock ecu which is preset to throw a fuel cut at a certain MAF hz, the 1g MAF itself which is only good up to about 2000 hz, and the fuel pump which runs out of flow. Stock injectors are 450cc.

Good sounds are important! Ask anybody who is into Ferrari or Lambo.
What do I enjoy about my car when I'm riding around at 40 mph? I enjoy all the extreme stuff - the hard suspension, the loud exhaust, the loud blow-off valve, the compressor noise.
For loud spool, the loudest turbos are the ones with an anti-surge compressor inlet. These are bigger turbos though.
But if you replace the stock rubber intake with a metal intake pipe, and put on an air filter like a K&N or whatever, it will let out a lot more sound from the turbo, so even a stock turbo or a 16g will make some nice sounds.

 

[widebody1g]

we're on boost!, thank you very much you were a big help and with your information and the information of other's ive got all the answers i was looking for and i should be good from here so once again THANK YOU everyone!

 

[POS_Tsi]

So my stock turbo is taking a crap on me (had some shaft play since I bought it)

Suggestions?

I have a tune-able Maf and a manual boost controller

I'm somewhat new with this, what turbos would bolt right up? could I go to something like a evo3 16g with only having the MAF and boost controller to "tune" it?

I'm not looking for huge power gains, but something with a little more "umpf" and mainly because the stocker has shaft play.

Would it be worth my while to have my turbo rebuilt? maybe have it ported with a bigger compressor wheel, or doesn't anyone do that with the 14b?

Thanks!

 

[92AWDHX40]

Your goals 14b is good evo great turbo i would get my 14b fixed cheap enough and still fun for your set up.

 

[POS_Tsi]

Any one know where I could get my turbo rebuilt? Also anywhere that could port it etc

Thanks!

I just bought a ram horn style manifold.I was wondering what Turbo I should run with it?

GT42R you don't need fuel mods of any kind and you can go low 7s with it and around 950WHP.

Not really, but seriously. You need to let us know what kind of flange it has and what your power goals are or we can't help at all.

What kind of supporting mods do you have or plan on having to run the turbo?

 

[dsmjunk]

Its a t3 flange. I'm going balls to the wall with this since I have to rebuild the motor anyways.
