Ok so,

Right now I have a 14B that has a small oil leak into the turbo.

I was going to get it rebuilt soon. Until I found a couple 16Gs. One is a new small 16G and the other is a Used Big 16G

My car is an automatic so going from a 14B to a 16G will slow down my spooling a little I ASSUME. So what I need to know is will it be my best choice to go 16G or rebuilt the 14B. If I do go 16G whick one? The new small 16 or the used Big 16.
 
your car came with a 13b from the factory.the 13b is smaller than the 14b and16g series. they will not bolt on to the 14b manifold while on the block because of clearance issue.

You should stop posting.

Any if the listed above will bolt up. Depending on goals in mind, I would get the 14B. Plenty peppy enough, and will run well when pushed.

Everything that you said is incorrect. All 2g turbo cars came with a t25, not a 13g. A 13b is a mazda rotary engine, a 13g is a 1g auto turbo. A 13g, 14b, t25, small, big and evoIII 16g all will bolt to a stock manifold no problem.
 
My car is also an automatic, and all the turbos you listed bolt right up with little to no modification.
 
Thank you all (well most of you) for the replies. I am aware that all of these turbos will work with my car.
What I want to know is which one is the best choice for my setup.
All three will be about the same price so I just need to pick the best one for me.
 
Which one is the best for you? I don't know. What are your goals?

around 320 whp... big 16g
fun street car and at times pedal to the floor to merge on freeway small 16g.
turbo just for the heck of it, the cheapest one of the three.
getting ready to snap neck when turbo pulls the bigger one of the three.
Just being sarcastic but you see where I'm coming from. LOL

Without your goals in mind, we are clueless as you!
If your worried about spool time, get the smaller one.
 
I just want what everyone wants. The power of a Ferrari, the handling of a Porshe, and the fuel economy of a Hyundai. Lol

Really I'm tring to get the most horse power I can right now without making the car a pain in the ass to drive everyday.
 
The big 16g is the best DD turbo in my opinion.. Great power and spool... You won't be disappointed, go with the big 16g, but also consider you may want to look into more fuel and maybe ECMLink. As long as you keep the 16g on stock boost levels you should be okay, but it won't be the best for power at such low pressures, a 14b might be more up your alley unless you do plan on upgrading fuel.
 
^ If your spending a pretty penny for a 16g, just skip it and go with the 20G. I had the 16g before I went to a 20g on my old motor, and after owning both, I would not waste my money on the 16g. The 20g will spool as quick as the 16g, but with more pep. IMO, the 20g is well worth the money and is great for a daily. But if you want even quicker spool, stick with the 14g, or get a small 16g. But if you don't mind a very little loss in spool, then I would go with the 20g.
 
I've got a B16G, I'm auto and its a fun peppy turbo. I would recommend that. Make sure you have all of the supporting mods and a way to monitor/tune them for the best performance.

Dead wrong. 13g is 1g auto.

Actualy a 13g on a 2g is not a bad idea. Same idle insta spool with a more reliable turbo.

But a 14b is never a bad idea as far as turbo output or spool. 14bs can do 20 psi, and spool very quick.

When you go to small 16g your only sacrificing about 500 rpms of spool, with more compressor efficiancy,and flow. Then goes your big ,and evo 3 turbo as far as flow.
 
I finally got pics of the "NEW" 16G turbo.. I'm pretty sure its an Ebay Turbo..
Here is a pic. Am I right?

Stock 2g came with a t-25 ...My plans are going with the 20g after i got all my supporting mods ready. (Fmic,fuel upgrades, intakes, exhaust, and monitoring system) .. exhaust is ready hks hi power...
 
You know I see all the eBay shit and I'm wondering are they even effecient like the oem units?
 
I had a crappy eBay 16G turbo thrown in with the Talon I bought last year because the car was in pieces and he didn't have the stock 14b. I personally do not trust it but I'm just going to run it until it blows. Since you have a choice, I would run anything but your eBay turbo. Feel free to give it a shot though. Just realize these things are hit and miss.
 
If your going with a 16g, your going to need supporting mods with it. If not, go with a stock turbo
 
^ You don't "need" supporting mods to run a 16g at 10psi, but anymore than that and you will. I ran an Evo3 16g at 12psi hitting well over 90% IDC's.

I just rebuilt my whole motor in my 95 Talon TSI. I put a small 16g turbo, 16g turbine headers, aftermarket inter cooler, 255 Wal. fuel pump, and I have a set of 880cc injectors, that I didn't throw in yet. I also put on a fuel regulator, boost gauge.. My car holds 20psi/idling. But as soon as it hits between 7-10pounds/psi. The car shakes/wants to shut down.. Wtf is going on with it? If needs tuned etc. How can I do that? I don't have no dyno's around here for AWD.
