Ported T-28 versus ported 14b on 2g

[calico]

Which would give the most noticeable gains on a 2g? I have found good deals on both and would like some opinions on each. The t-28 is a straight bolt on which is one good thing, but the ported 14b is much cheaper.

 

[Semprini]

the ported 14b.. its basically bolt on too. You can buy an install kit or Ive seen people use 1g jpipes and the 1g oil lines

a stock t25 flows 250cfm and a stock 14b flows 450cfm...

clearly

 

[deletrius]

how can a 14b be stronger than a t28? a t28 is essentially a 16g. not as strong as a 16g but still stronger than a 14b.

A T-28 is NOT a T25... Now, is it a BIG28, or just a T28... in either case, it should be a noticable gain at equal boost levels, plus flow great at higher boost. IF you plan on sticking with mitsu turbos in the future (i.e. 16g variant, or 20g) you may as well get the 14B and install kit. If not, get the T28 for ease just bolting up...

The 28 should outflow the 14B hands down, but it's up to you and your wallet.

A T-28 is not a 16G. A T-28 has the compressor and turbine housing of a T-25, but with fitted with larger compressor and turbine wheels. I have in mind this T-28.

I would like to add that many 14b turbos are over 10 years old, and are cracking from old age. If you are planning on sticking with this new turbo for a while (perhaps a couple of years), I would for-go the idea of a 14b and instead install the T-28.

T-25 < 14b < T-28 < Big T-28 < 16g < E316g

As previously mentioned, it all depends on your goals for the car.

 

[romeen]

The T28 will definitely outflow the 14b and give you better gains.

What DSMunknown mentioned about the aging 14b turbos is important. It's hard to find one without cracks and worn bearings.

apparently I need to brush up on my reading skills.. my bad

 

[calico]

Looks like a winner with the T-28...thanks for the input......It's a FP T-28 ......

 

[just2asian]

Actually I saw on a website that someone posted that a FP Bigt28 flows just as much if not more than a Big16. Obviously it's more money, but just something to keep in mind. I found the link but it is no longer active, it had flow numbers for a huge list of turbos.

I have a big t28 on my car. I have it set for 20psi and it pulls really hard. My friend has a 16g on his car and it is dead off the start. He is always trying to trade me turbos and cash. My opinion is the big t28 ported over a 16g. I drove in both cars and I would say the 16g just doesnt feel as strong.

Wanted to add, the big ported 28 is going to cost you a pretty penny. I paid about 900 shipped over night with SS oil line.

I'm expecting big gains with a ported fp t-28 and fp new exhaust manifold.

right

The Big28 should flow more than a plain-jane 16g, but it wont top end over an EVOIII 16G
The difference is the 28 "hits" a lot harder. Boost comes on fast and strong, and early. the 16g takes a bit longer to spool, and doesn't peak quite as aggressively

Farnorthracing did get 350AWHP out of a 2.0l with race gas at 24psi though... that's pretty decent.

I picked mine up used with the adj. actuator for 400. had FP port it for a little more.

That's pretty much all i need for a daily driver. Not looking for an all out racer....

thanks....

The t28 spools up so fast. I am at 20 psi by about 2500 rpms. I dont know about a 16g catching back up at top end. I dont know about the rpms on a 16g but I know it isnt that low.

I'd be interested in seeing this. Use this website http://www.archive.org/index.php to get the page and post a link for us!

My EIII b16g hits 20 psi right at 3300 rpm and pulls quite hard all the way to redline. I don't have any experience with the T28 so I cannot say how it would do vs the Evo3 b16g, but that is not what this thread is about anyway.

 

[Big28 2gFWD]

i have a ported fp big28 for sale (used for 4k) miles pm if interested!!!

 

[gsxeclipse97]

well it looks like you are just comparing a unported 16g to a ported t28 so i would like to introduce that if you ported the 16 or e316g it should easly take the down a t28.

 

[dcg9381]

So I'm missing something.. The T25 / T28 are typical Garrett flange sizes.. They don't define flow for a specific turbo. Course, I'm a noob.. which is why I'm in this forum.

 

[PieEyedPiper]

maybe, except that boost will still come on sooner with the BigT-28 no matter what you do.

 

[GSXspeeddemon]

FP big t-28 has a 550cfm flow rate which is the same as the big 16g.

so then.
T-25 < 14b < small 16g<T-28 < Big T-28 = big16g < E316g

My opinion....t-28 better for awd, 16g for fwd....

 

[gsxeclipse97]

Well that depends on a couple of things really, boost is just a down shift away with the e316g so its not that big of a deal. The t28 would be better for throtle response for just crusing So why not go with the bigger turbo for less money. I personally would go for the e316g but i have other things that help the throtle response. you may feel more torqe with the t28 but torqe is going to win the race. Also the t28 still has the same compressor housing that the t25 comes in so flowing twice the air is going to make the air hotter comming out of the t28 than from the either of the 16g's so really the 16g is a more effecient turbo.

14b 405cfm
s16g 450cfm
b16g 505cfm = t28 if compared to the 16g
e316g 550cfm
