Big T28 Who's got'em and what do you think.

[Precision]

Ok, I'm getting out my 2g awd from storage. I've been so busy with work I havn't seen her in a year. I'm wanting to run under a 12.0 in the quarter and already have:

Apexi front mount and HICP
walbro fp
HKS ssqbv
Crower Stage 3 cams
1g head fully race ported with 1mm OS valves
1g intake
1g throttle body
3" o2 elimatior mandal bent exahust
Ingien hard intake pipe

Basicly, all you can see under the hood is the IC piping, and the BOV. I'm trying to keep it looking as stock as possible under the hood. I was leaning towrds the FP Big T28, I read on thier page that they ran a 11.82 with a 2g. Is this feasable? I would like to hear form guys that have this turbo, and what they think of it. If not the FPBT28 then what, remember I want to look as close to stock.

P.S. I am aware of the supporting mods I didn't list.

It is possible but not feasible. EVOIII 16G, 20G, or 50 trim would all be far better choices. There are many dabates about the effectiveness of the T28. I have one and IMO it's the worst DSM part purchase I've made to date (I've banished it to my winter beater) but some guys actually like theirs.

I was leaning towrds the SBR Big T28, I read on thier page that they ran a 11.82 with a 2g.

I believe the turbo you are talking about is the <a href=http://linux.forcedperformance.net/merchant2/merchant.mv?Screen=PROD&Store_Code=FP&Product_Code=NTDSMFPBIG28&Category_Code=DSM-Turbo>FP Big T-28<a/> FYI (read under the title "Thank you, drive through" )

The T-28 flows less than the 16g, and you really want one? Shops can take "anemic upgrade" turbos and run good times because they have more resources at their disposal. Exceptional times on those turbos is the 'exception', not the rule.

 

[Precision]

I'm not "wanting one" I'm simply researching. As I said before, I want the car to appear as stock as possible, which is not possible with a 50 trim or a misu turbo. However If need be I might bring my self to buy a non-stock appearing turbo.

 

[ryboj]

They're right, the T-28, ie. FPBigT28 typically will not run under a 12. FP's gains were exceptional, not ordinary like mentioned, as you'll see from searching this site. I was looking into the same turbo, and I find it will take a lot more to get this turbo into the low 12's, let alone high 11's, plus traction can be an issue (at least in the FWDs) as it tends to have a big hit off the bottom early in the RPM's.

I would consider the stock looking Evo3 16g, 18g, or even a 20g, but internally gated to keep the cost down. Any of these turbos can get you into the 11's, maintaining a relatively stock looking setup. I'm of the same mindset.

It works great for applications in which you need instant power prettymuch anywhere RPM wise, but for those times you will need much more top end than what a Big28 can provide.

 

[VRMAN]

Forced Performance has the 18G on sale for around $660 bucks, I would look into that. Although not "stock" for a 2G, the td05 comp housing is still pretty small and would appear stock on most cars. Spool time is excellent and it will provide better top end over the T28. I had one on my car for awhile and it was excellent for quick spool and immense mid-range punch. You can get about 330hp out of it with supporting mods and if you are AWD then high 11s is possible.

The Kid who sold me my car 3 years back had a FPBigT-28 on it and i blew it up in only a month. i got it fixed and boy was that a mistake. Dont get me wrong, its a great turbo and i like the immediate power it provides and the power it added but like everyone else who has/had one, i would have went bigger in the first place rather then getting it again i.e. 16g, 18g, or 20g.


so decide what you want. Lots of power or a fun "zippy" car.

 

[98eclipseRS]

had it sold it after a month, waste of money if you ask me just go big the first time you won't be happy with it trust me.

 

[Black95TSIawd]

a fellow njdsm member, and i believe he's a member on here too, went 12.2 @ 110 on PUMPGAS with an FPBig28. Look for his thread in track talk.

I owned one for about14 months, and would have kept it if I hadn't spun a rod bearing. There is a HUGE difference between teh BIG28 and a regular t28. The t28 is just a stock turbo w/ a different wheel, while the BIG28 has larger compressor and exhaust housings (larger meaning inside, from the outside it looks the same). The BIG28 flows between 36-38 lb/min, and the EVO III 16g has been recorded at about 42 lb/min of air in a couple instances. The difference between the two though is that you will get full boost out of teh 28 by 2800-2900rpm and it will look stock, where as the EVO turbo will get boost around 3400 rpm and not look stock. I loved mine. I ran an 8.54 in the 1/8th mile (only track we have) on pump gas and stock injectors at 17psi. I know numerous people have made 335+whp with the BIG28, and there are a number of 350hp dyno graphs out there. People can hate on it, but I say dont' hate unless you've used it. Remember that a t28 is not a big28. Oh, and as far as your 11 sec. passes on the big28, it'll be hard to get there (esp. w/ fwd) but it can be done. A better choice might be an internally gated 50-trim with the t04B cover (the smaller one) and a welded on 90* elbow to look stock, which flows about 50lb/min of air.

i had a fpbig28 and it sat in my room waiting to get put on longer than it was on the car. it wasn't a bad turbo. i just didn't like that it spooled so quick with my fwd because it was just all out wheelspin. if you want a completely stock looking turbo i suggest the fpbig28, if you have the slightest feeling you might want a bigger turbo down the road, go big the first time

 

[Prodigyman]

Great thx for flaming my first turbo! I have AWD GSX and love it! Providing I have about 100 boost leaks ATM but still its MUCHHH faster then STOCK T25 WITH no boost leaks. I got 31” FMIC and waiting on FMIC piping kit from English racing and we shall see how much it sux IF u AWD quicker spool up times and BOOST to the red line for the win!

 

[ShapeGSX]

The BIG28 flows between 36-38 lb/min, and the EVO III 16g has been recorded at about 42 lb/min of air in a couple instances.

44lb/min on my car, actually. Very cold that day.

The difference between the two though is that you will get full boost out of teh 28 by 2800-2900rpm and it will look stock, where as the EVO turbo will get boost around 3400 rpm and not look stock. I loved mine.

My Evo III 16G hits 15psi by 3000RPM in 3rd gear.

 

[pboglio]

The FPBig28 turbo is maxxed right around 37-38 lb/min, thats about 380 h.p. That puts a full weight 2g AWD (3320 lbs) right around 12.0 @ 113-114 mph in the 1/4 mile using the calculator. That is also beating that turbo within an inch of its life though.

I run the FPT28/28. I like it on the street, won many races against quick cars. That FP 11.82s @ 119 mph run must have been done down hill on a -50*F day, because that mph and the compressor flow don't add up. I'd like to see the datalog from that run myself. Do yourself a favor and buy something bigger.

 

[theSicKness]

ive got a fp t-28 installed on my car and i love it..its a huge diffrence than any other t28 and if uve ever talked to the people from forced performance there car they ran the 11.82 on wasnt even heavly modded the guy told me he had some head work 550cc injectors fuel pump and safc 2 and race gas 3 inc exhuast and intake...

so if ur looking 4 a t-28 go w/ fp you wont be dissapointed...

My Evo III 16G hits 15psi by 3000RPM in 3rd gear.

Impressive flow!

just on a side note, I hit 23psi at 2800rpm with the big28, and actually hit 25psi at 2250rpm w/ the big28 on my stroker motor

 

[FourG63 97GST]

my best time is with my T28, which was a 13.5
I was making about 250hp/250tq which is crappy.

12s shouldn't be hard with an awd

 

[fastaseagle]

i had a fp 28 not the big t28 went a 13.0 in a fwd on 18lbs with the stock clutch i think they are good turbo to make around 300-350 hp which i a awd is goof for low 12's probably to high 11's depending on the driver..

 

[IMMORTALSPYDER]

My Evo III 16G hits 15psi by 3000RPM in 3rd gear.

My big t28 killer (yes I know it's a different turbo) hit full boost by about 2500 after I put on a full turboback. I didn't lose traction when it spooled like everyone thinks, I broke loose about 4-5k when the powerband really climbed.

In what gear? And what is "full boost?"

It matters. In 5th gear you will hit a certain boost level at a lower RPM, but more slowly in terms of time than 3rd gear.

This is why I like the standard of 3rd gear.

But frankly, these turbos are both in the same ballpark for spool! It isn't like the 16G is a lag monster. In terms of top end, though, the Evo III 16G does really well for its size.

 

[IMMORTALSPYDER]

2500rpm in 3rd gear, actually any gear. Full boost for me was about 15psi.

 

[ShapeGSX]

If you get full boost by 2500RPM in 1st gear, it is only because your car is slow. I'm not saying your car is slow, I'm just saying that I don't believe you can get 15psi by 2500RPMs in 1st or 2nd. 3rd, i can believe that, but I have no idea what size a T28 "killer" is.

The gearing in 1st and 2nd is so steep that you should be sailing past 2500RPM well before the turbo can spool to 15psi.

 

[cait sith]

I've liked my "Big" T28, it's a great autocross turbo, spools up faster than a relatively stock EVO8 on the autocross circuit, but meh, I'm a bit tired of its limiting factors up top around the 5-7k range. Although maybe if I threw a few more degrees timing up top, I digress....

Excellent response, ez installation for even the dumbest of the dumb (Throw on a braided stainless feed line for even more), stock apperance for those that care, and easy to hook up for piping with long route piping.

I wouldn't bother upgrading from a Big T28 to an EVO16G, unless you blew your Big28. Something with a ball bearing center cartridge and a big external gate is calling my name now...
