Evo III 16g v FP big t-28

[blackGSX2g]

Hey guys, I'm upgrading the turbo in my 2g AWD turbo. and I found two turbos, same price. Its between a brand new evo III 16g with the install kit for a 2g, or a 4,000 mile FP Big t-28. I have a logger, MAFT, and am getting 550s, so I have the basic supporting mods for both. I am hoping to run between 15-17/18 psi depending on octane, and want the quickest spoolup that I can get while still having good top end. I've heard both good and bad from both turbos, and was just wondering if anyone had experience with either. Let me know! Thanks.

Just responding to what you asked.from what i know with people i know running both .The evo will outperform the big 28 like there is no tommorw .The evo is capable of getting you into the 11's if your good at tuning and good at driving but the big 28 i've only heard of low 13 maybe high 12's i would get the evo that was what i was gonna but untill i heard about the bb gt just letting you know what i know

if you dont get the evo ill #### slap you

Forced Performance ran 11's with the big t-28 on a full weight eclipse. Check the website. The EVO III flows more cfm's than the t28 and it will hold boost better till redline. The EVO III is a better turbo IMO, same spoolup and more topend power. If you want you turbo to look stock get the FP big t28. If you want your car to be faster get the EVO III 16g.

this subject has been beaten to death try using the search function next time.

EVO 16G
+ flows more
+ cheaper
- not true bolt on some mechanical skills required
- spools slightly slower

T-28
the exact opposite

You missed a point.

The evo III 16g doesn't flow that much more than the fp big t-28. I belive the evo III flows around 550 cfm while the t-28 is at like 530.

Spool up in the t-28 would be better, plus it would be a true bolt on.

I suggest you do a little research and figure out what you are looking for. I'd go with the t-28.

No, the standard 16g flows 505 cfm while the Big 16g flows 550 cfm. I don't think I have ever seen a cfm rating for the Evo III 16g but with the larger compressor wheel I'm betting it's a little higher.

 

[1badtsi]

dont forget the evo has lighter internals and a 2.5" turbine exit

Hands down you'll get a better deal with a evo3 16g even with the install kit (or you could even piece one together). Unless you find a killer deal on a big t-28 and don't plan on hitting much more than a high 12, get an evo3.

The Mitsubishi TD05 turbo bearings are better than the T25's bearings. A lot of AutoX guys really push their T25s, and it isn't unusual to hear about the bearings wearing out.

A T28 will not have to spin as high, but it still has the T25 guts inside.

The big t28 makes full boost before the big 16g starts to spool... whats that a half second off your trap time? plus its a direct bolt on for 2g owners

Wow, that must be really fast spool then.... Seeing how i get 10psi at ~2500rpm from then, it hits full boost at ~3000rpm. That's 18psi on the EVOIII 16g.
So, you're saying that the T-28 would be at full boost before, say, ~2300rpm? Because that's when my evoIII starts to spool....

WOW WHO BOUGHT THIS BACK FROM THE DEAD

Any since my last post i have gotten a EVO 3 16G and i have beatin my friend with Big T-28 by 1 1/2 car lengths. I reach 16PSI around 3200 RPMs my friends reaches 16 PSI around 3000 RPMs (both of our mods list are the same just different parts)

That is a most excellent sig pic my man....
Evo's sure are sexy in yellow....

If you read the description on FPs' site about the "Big28" (not T-28), it also says "at 21 psi". I have asked Robert personally what was up with that car that went 11.87 @ 119, if it was just a freak of nature, or if this turbo in question is really that bad ass. He said the car was a 99 GSX, 3" exhaust, FMIC. 650cc injectors, cams, 1G 60mm throttle body, BPR6ES plugs, fuel pump. He said that they were getting a HUGE spike up to 25-26 psi and holding 21-22 steady. Big28s' build boost so fast. If your car is gonna see less than 20+ psi on a daily basis get the EVO III. A Big28 at less than 20psi will not blow away your expectations. Get it up on 23-25 psi and hold on for dear life. A smic is not the recommended charge air cooler though. You "need" ALL supporting mods to see the potential a FP Big28 has.

Oh and Big28 don't boost creep, the porting done by FP is top notch.

Its a toss up.

[blackGSX2g]

Wow, never thought I'd see this one again...

I got the EVO III 16g and never looked back. Very glad I did, I get 15psi at just a bit over 3k. After doing more research, the only advantage in the least to the t-28 is its direct bolt on characteristics, but after doing the swap, even that is marginal. Its not that hard to put a 14b/16g on at all.

The big t28 is an AWSOME turbo an a phase 4 ej22t hybrid, so good i keep putting off buying a t3/to4e

EDIT: Its an awsome turbo on an ej22t hybrid in a 2600lb car

A buddy of mine with the FP Big28, 2.5 downpipe and crush ment exhuast, 272, 550s, afc, 255 and stock smic dynoed 295hp at the wheels with about 23-21psi. Then he blew up his engine racing a Stang on the highway.
Both turbos have virtually the same compressor wheel. The marginally bigger compressor whell on the Evo really does little measurable good for it. There are no "lighter internals" on the evoIII. I have personally called and spoken with a person who builds and sells these for a living in Texas. EvoII, FO big and Big16 all are rated at 550cfm. The Evo has the better turbine housing, thats what is good about it. The evo and regular big both have TD05 turbine wheels, which will give them better top end the the FP big.
I have the Big16g and I see full boost at 28-3000rpm.
You will not be disapointed with the Evo. The 28 will leave you wanting more.

I've spoken with FP about the Evo III 16G. Those CFM ratings are a load of crap. How can different compressor wheels be rated at exactly the same CFM? Especially when FP says that they are rated at different lb/min limits?

The Evo III 16G is definitely lighter than the big 16G due to the thinner shank and the thinner blades on the compressor wheel. That is why the Evo III spools up faster than the big. And that is why it flows more air than the big. More free area at the compressor inducer.

The compressor maps are different, too.

 

[skier_du]

Yes, the evo and the big are different, but not hugely. I have spoken with Turbochargers and they say that the hype is just that. There is not a large enough difference in the compressor to even rate it more than the big for hp ratings. Most of the spool up is due to the turbine housing. The also told me there is no weight difference exept in the turbine housing itself. Their websight does say that the turbine scroll is smaller, whcih is what contributes to the quicker spool. The turbine housing, slightly larger exducer, not sure but the nozzle may be different size, so all this gives it a very slight advantage over the big.
If I had to do it again I would get the evo, but my big is just fine.

Frankly, they are wrong. In fact, just about everything said above is wrong.

Why on earth are you trusting turbochargers.com? Why trust one sentence when you can actually read real facts about each turbocharger?

Here is a real comparison of them.
http://www.slowboyracing.com/Mitsubishi Turbos/EVO 16g/Wheel_comparison.html

The turbine scroll is identical to that of a normal 7cm housing. As is the nozzle, which is 7cm^2. The TD05H turbine wheel is identical to every other TD05H out there. The only difference that might make a performance difference is that the turbine exit tapers out to 2.5" where it mates to the O2 housing.

The difference is in the compressor wheel. The compressor wheel blades on a big 16G are 0.03", and 0.015" on an Evo III 16G. Half the thickness means a lighter compressor wheel, and it also gives more free area for air to flow through the compressor. The shank of the compressor wheel is also MUCH thinner than a big 16G. This also gives more area for air to flow through the compressor that is just dead on a big 16G. As well, the inducer of the compressor is 0.01" larger than the big 16G. Even more area for airflow at the inducer. In fact, in terms of open area at the inducer of the compressor, an Evo III 16G has an area that is closer to an 18G than a big 16G. And less mass on the compressor means a faster spoolup.

Check out the maps (Evo in blue, big in red):

The Evo can flow a quite a bit more mass than the big. The map islands are larger. And in general, it is just more efficient. And all the data I have seen on my datalogger supports this.

 

[skier_du]

Perhaps they have their own wierd brew of the Evo? Dunno about them. I have also seen that info before from SB. I agree that the Evo is better than the Big, as I said, I would get that one next time. It wasn't readily available when I got my big a couple years ago. Wouldn't you agree that full boost well before 3k is still pretty good spool? Even transiant is quick. I'd love to try an Evo on my setup for spool's sake. If my big can spool this well, why bother with a 28 because of spool, might as well go with evo and spool the same as 28 and get better flow.
Anyway, enough. We agree on get the Evo, it's an awsome street turbo that will put a big smile on yur face, that's what this thread is about.
