Hmmm, Big 16g or Big T-28 for my first turbo upgrade.

[boostin97talon]

I'll be getting a turbo for my car in the near future, and would like to hear from people that do or have owned a big 16g or big T-28 on there 2g. I'm just looking for some pros and cons from people who have spent there hard earned money on one, instead of reading 'advice' on them from shops who would like to sell me one. Thanks.

I would say the Big 16G. It realy likes higher boost levels and is a killer drag turbo. From what I have seen there are alot of people that are trying to get the fast times out of the Big28 and are having trouble doing it.

 

[gsxtacy]

Well, my vote is gonna go for the FP Big T28. The B T28 in my car has not hiccuped, burped or farted and I have about 3,000 miles on it now. I don't have the fuel mods, so boost in my car is limited to 17-18psi safely. You can really feel the difference over the old T25 and it was a breeze to install, took 3 hours (and I was taking my time!!!!)

I believe I am at just 60 % of this turbo's potential. Definetly the T28 if your AWD, if your FWD its a toss up. The mutha spools on my car around 3400 and pulls all the way to 7200 where I shift. Well there's my vote.

Honestly I've rode in cars equipped wiht both. They were almost identical at the same boost level(15psi). the only difference is the BIg28 spooled a little quicker and the Big16G well pull a little better when you crank up the boost past 20psi. Honesly it's a toss up to me. But I'd say go witht he Big28 if your more of a street car, if your more of a track car go with the Big16G.

 

[Blitzed95Eclips]

im also wondering what turbo to get for my first turbo. on a 2g gst. what are supporting mods i would need for the big 16g?

ps. i hope you smoked that mustang

I rode in a friend of mines car (Big 16G, exhaust, ic pipe, 1G bov, 550cc injectors, afc) and he had 18 psi at 3400-3600 rpms.

The biggest thing the Bigt28 has going is that it looks stock and installs like stock.

 

[sunflashx]

Big16g for 1g cars
Big T28 for 2g cars

Simply for the ease of installation. Both turbos are very comparable.

 

[Blitzed95Eclips]

can i buy this big t28 and bolt it to my 2g gst without other supporting mods?

i already have intake, exhaust, bov

how much hp will this bigt28 give me?

 

[IPT]

To get the most out of a big t28 you need larger injectors and fuel control.

 

[Blitzed95Eclips]

whats fuel control

can you please give me a site. i appreciate your help

 

[IPT]

Here check it out in the parts guideAir/fuel control

 

[Blitzed95Eclips]

ive seen those when i was looking for a boost control

so do i need the apexi boost control and the air fuel gauge?

the Big28 is a nice turbo but Ill tell you ahead of time you really need to have set goals on how fast you want to go and Ill tell you right now if you can do it or not.. AWDs are barely breaking into the 12s with the turbo and FWDs are fighting for traction becuz of the insta spool of the turbo..

 

[boostin97talon]

I'd like to be in the 12's on pump gas. My car is AWD, so I know that will help a ton. I'm considering the big 16g, ported and clipped, with the rotated compressor housing and 90 degree elbow from TRE. I may go with a bigger one than that in the future, but I want to see what I can do with the big 16 or T-28. My goal is to be the guy at the track that is putting out rather impressive times (mid to low 12's would be great), that people look at and say '... and he only has a 16g, (T-28)', obviously depending on what I choose. And no, I don't expect to see times like that without a fmic, cams, and magical tuning, I know it'll take some work.

All our locals running similar turbos are having pretty good luck with them. The traction problem of "insta spool" doesn't seem to be that bad if you know how to drive.

My friend with a 97 GST ran a 13.8 on street tires. He's running a full exhaust, FP Big T28, MBC, K&N filter, dejon intake pipe, greddy IC pipes/bov. His only fuel modification is a reqired stock pump. This is all done at 4600' altitude. Full wieght minus the spare and jack.

Another local ran a 13.06 with a 97 GS-T on a standard T28. He was running race gas (110 oct) and drag radials though. Mods include full ported mani/turbine/o2, full exhaust, profec, SAFC, injen intake, fuel pump, rre IC pipes, greddy bov, 1g TB, underdrive pulleys, JUN lightweight flywheel.
Once again, at 4600', full wieght minus spare, jack, hatch cover and I think he pulled the passenger seat while at the track.

FWIW, my Big 16g has ran 12.04 on a stock SMIC. But you for sure needs fuel mods to run these turbos to their potential. If you plan on boosting above say, 15-17 psi, I think the Big 16g beats the Big 28 then. Plus, I believe the Big 28 is on mega-backorder, my buddy ordered one 2 months ago and still doesn't have it.....

 

[SPEEDY]

There is just not enough people yet IMHO that have the Big28, as compared to the Big 16g. That is one reason you will see better times posted with the Big 16g. Both turbo's are capable of 12's. High 12's for fwd and very low 12's for awd. Plus... you can't beat the direct bolt on fitment with the Big28. I say Big28. My car runs very strong at just 17 to 18 psi. I have run neck and neck with a stock c5 vette with my Big28. That was with 16 inch konig Villains and drag radials. No spare tire or jack, and no back seat. It's a perfect turbo for the street.

tell yer buddys to get their times posted on dsmtimes.org and on dsmtalk then.. I ran a 13.7 @ 109 with my Big28 with supporting mods and prolly coulda run low-mid 13s but high 12s would mean some really good driving..

Damn!! Those times are killer to be at 4600ft in elevation. Both of those cars are definitly high 12 to low 13 sec cars at sea level. Sure as hell makes me feel good. I'm at 2210ft above sea level!

 

[Black_Bullet]

In this range of turbo, Evo316g imo.
Spool times will be what like 100-200 rpms different between it and a T28 but yet the evo 16g has much more potiential in the higher boost levels....

 

[400HP1GT]

I also like the EVO III on a street setup. Works great with Comp 200s, at 20 psi.

 

[deflator]

Find yourself a Big T28 Killer. Its a turbochargers.com hybrid; Big 16g wheel in a housing that mimics the t-28, so it bolts right on a 2g. I like mine, and it came free with the car

 

[turboglenn]

I can't speak for the T-28, but my first upgrade was the b16g and i loved it. The spool was sitll almost instant (especially compared to what i run now) but there was nothing i would call noticable as far as lag. The pull was insanely sweet through the 3500-5k rpm range where it made gobs of torwue and pulled like mad. The only thing i didn't like is how it would fall off above 22psi at the track, so i went bigger. Now i wish i would have gone some where between a 16g and t3/4 hybrid (namely a 20g).

The 16 is great fun on the street, the quick spool soupled with some torque steer make for a good time! THe only "con" i can think of with this turbo is that it doens't support the kind of top end I was after when i cranked the boost up at the strip. But for a daily driven car i think a 16g is just right for 80% of DSM owners , especially the EVO III unit which is proven to put down good numbers and still spool incredibly fast.

I hope the OP was able to make his decision after 6 years.

The Big T28 can be pretty pricey especially if you buy it new. That being said it is relatively problem free=Direct replacement. The Big T28s seem to be less prone to boost creep than the 16gs. It is an easy turbo to install on a 2G. I have to get bigger injectors, and fuel management to really open it up. I have pretty much all the other bolt on mods. The Big T28 at 17 psi did not like the stock SMIC. I got some surprising heat soak that hadn't happened at all with the stock T25 at the same 17 psi. The FP Big T28 flows a lot more air at the same psi than the stock T25. I really haven't opened it up anything past 17 psi yet. I installed a Hahn Racecraft smic and it took care of the heat soak issues. I did practically all my other bolt on performance mods before putting on an upgraded turbo. It seems to work flawlessly even without fuel/ ignition management. I am running an Aeromotive afpr. I can't wait to race this setup this summer (autocross and maybe even a few runs at union grove.)
