Which is faster spooling? Fp big 28 or Evo3 16 g?

[Attack Eagle]

T28 vs evo 16g

which one spools faster (lower rpm) at about 17 18 psi assuming the same mods, downpipe o2 catback race cat etc...


I have not found anyon who cna say they swapped from one to the other and where the boost came on on the same car.

I like throttle response a lot and would gladly give up some hp if necessary to keep spooling at about 2.5 k vs 3 or 3.5 that I see is generally the norm on evo3s...
I drive in traffic and it's real point and shoot type of stuff, I can't wait around to make boost and i don't need the fastest car out there...


Anyone with first hand experience?

T-28 spools faster

T-28 spools faster

It spools up almost as fast as the T25 with gains in the mid and top end. Most people claim that the EVOIII provides better top end power than the T28.

It spools up almost as fast as the T25 with gains in the mid and top end. Most people claim that the EVO VIII provides better top end power than the T28.

EVO VIII? I though that turbo wouldn't fit out cars?

Ooops. I meant III. Thanks.

....
Evo3 has more topend is what everyone says.
The t28 is faster spool tho.


So whichever you want that should help you somewhat.

I kept thinking I was going to buy the T-28, but I kept reading that the boost comes on all at once. Is this true? Would the EVOIII be a smoother boosting turbo? Thanks. Sorry for hijacking.

 

[95gster]

sometime I wish I had faster spool up with my b16g cause everyone is beating me off the line but I know once I hit 2nd gear I'll be gone..........

On a FWD I suggest the evo16g or a "slower to full boosting" turbo.


Boost to quick and you will go through a set of tires and still would have not moved 10 feet.
:laugh:

 

[truwarrior]

It depends on how much boost you'll boost. I havn't seen the maps for the t28 or the evoIII, but I'm guessing the t28 is more efficient with lower boost but the evoIII can flow more efficiently at higher boost levels. At what levels I don't know.

If the T28 spools almost as fast as a t25, then the evoIII would have to spool faster then a 14b to be even close to the t28...

thanks for all the feedback guys... I'll probably end up going big 28 for three reasons...

one it will be my first turbo swap ever and it will be easier with the big 28, and won't raise any eyebrows if the car ever needs servicing at the dealer.

two I don' think I have ever gone to 100% WOT in my car, and probably won't run any higher than 17 - 19 psi boost. I don't drag race it, just like to out accelerate traffic on the street occasionally (especially when its an obnoxious civic or some other honda and he's trying to show off to the girl in the passenger seat), and maybe do some autox for fun, that extra 500 rpm or so waiting would annoy me, no matter how it pulls on the top end...
I'm off throttle before the end of second anyway.

three I read that boost creep can be a minor issue with the EVO 3 with upgrade housings down pipe cat and cat back, and simply don't want to have to deal with possibly needing to go external wategate...

OK, now that you picked a turbo, hit up the search area and look up the supporting mods. 17-19 psi is not a lot for that turbo but if you have no fuel mods you can only safely run at 14-15 lbs. And remember to get it tuned. They might be small but if you really wanna feel the power get it in the shop and on the dyno to be tuned out.

Oh yeah welcome to T-28's. I suggest getting the Forced Performance Big T-28 of the AGP T-28.

 

[dsm95gsxer]

I am new to the evo III but I get full boost at about 3500rpm with a stock head 2g mildly ported exhaust manifold (Ported to matchup to the 7cm evo exhaust housing) ported o2 housing, mrk IV intercooler, crappy stock dp and apexi 3 inch catback. The basics also brode uicp, 1st gen bov, 255 fuel pump and 60 mm throttle body. To a mild 15 psi no data logging yet I don't want to melt holes in my pistons. The highway top end is sooooooo much nice than my wore out t-25

before I go and put the turbo on I am going to go thru with all supporting mods:

install EGT, boost guage, and possible wideband (Aem)? like the simplicity of the AEM w/ gauge as far as reading etc. get used to what the measurements/ behavior are in semi factory trim.

Install upgraded pump
with the 255 lph pump, unless someone has a suggestion for a quieter than wlbro pump? From my research it appears that the 190 might be marginal at 19 psi but perfectly ok for 17 psi... and I might end up turning up the boost at some point...
fule pump rewire + 190 might be ok from what I read for up to 19 but is the 190ph quieter than the 255?
comments?

FMIC

ACt 2600 and lightened stock flywheel.

1st gen greddy profec b learn to tune the boost to a safe consistent level on the t25. 14-15 psi.

DSM link w/ 550s: make sure everything is good before I go and add the turbo and up the boost.


add dp and evo 3 o2 housing at same time as turbo and race /flowthru style cat.

I am hoping that this will get me the equivilent of the high 13's with the potential to go solid mid 13s after tuning.
Being a parent i don't have a huge budget so I have to plan out my mods for maximum potential to avoid replacing thngs twice or busting the car up as its my daily driver and family car.

 

[DSMPowerTSi]

With those mods and good tuning/driving that should be solid 12's. With a rough tune and 17psi with stock i/c I pulled 13.600 with a 2.11 60 ft on a slipping stock clutch.

 

[Rice Over Wheat]

Like everyone else said T28 spools faster. It's damn near the same as stock T25 just with far more top end potential.

 

[Attack Eagle]

thanks to all

This pretty much answers my ?s and thanks for the feedback.

 

[herostar]

If you're planning on going with the dsmlink to tune I'd strongly suggest getting 660cc injectors. The 550's are just enough for the big28 and are about maxing out their duty cycles at boost much above 22psi. The 660's won't cost alot more, and give you much more room for tuning. You also have the option of upgrading to a larger turbo down the road and not having to get bigger injectors then also. The larger injectors also won't hurt your fuel milage much as long as you tune them well. If you're getting all of the mods you have listed, you would also have the potential to run 23 psi on the big28 rather than 17-19psi. Trust me, that extra 4 psi will make a HUGE difference. Have fun and enjoy your big28, I know I love mine.

 

[Attack Eagle]

I think I might go with the e-boost boost system...

seems to be the easiest to use. that I have seen anyway! And truthfully it is no more expensaive than what the old prefecs were 4-5 years ago.

 

[neuralracing]

So is the outcome here that one should get the Big T28 if you want fast spooling (autoxing, road coarses) and the B-16G EvoIII if you plan on doing drag on 1/4 mile strips (not short 1/8 mile)?

From a tech inspection stand point... which turbo looks closer to the stock 14b?

 

[tigerstalon]

If you're talking exterior appearances, then...

The T-28 varieties are all basically modified T-25's, which are stock on 2G cars.

The 16G varieties are Mitsubishi turbos, as is the 14b, which is stock on a 1G car.

 

[dsmayhem]

If you want a quieter fuel pump I would look into a Toyota Supra TT pump.

http://www.diamondstarmotorsport.com/fuelparts.shtml
http://www.partznet.com/mitsubishi/mitsudsmclub.html

"Nippondenso made pump. Quieter than Walbro and much more reliable. Can supply enough fuel for high 10's-500whp"

Cost 2X as much as a Walbro as well. With either of those pumps (Supra TT or Walbro 255) make sure to include a fuel pressure regulator as well.

 

[scottsee]

if you do decide on the 255, i suggest looking into a fpr.
