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

[Gators453]

i have the fp big t28, its still only on stock boost (no fuel upgrades yet to raise it) but for what i want its a good turbo. i need a car that wont need the maintenance of a track car but is still peppy for when i do go to the track. i usually get full boost in 3rd by just around 3k rpm. i dont have a dp either so i cant really speak for its full potential. personally, i was more interested in the evo16g but this was just to good a deal to pass up so i went for it, thats why i dont have much supporting mods for a upgraded turbo. just thought id share what ive noticed so far.

EDIT: i have noticed however that it will hold its boost till redline. for me anyways, itll hit about 11 and settle itself at 10 until i shift, so thats a quality, but again once i raise the boost or get more mods who knows if itll still do this, but i just thought id add that in.

I have had the fp big T-28 for little over a year. Decent turbo for street fun, but does not seem to really come to life until about 15 psi, which means stock boost levels seem to produce similiar results as the stock T-25, with the exception that the T-28 will actually hold boost strong until redline. I have ran this turbo on stock boost up until about 2 months ago, i will admit i was very unimpressed until i added the boost controller and had some supporting mods to run 18 psi. I can now say that the T-28 is a fun turbo for the street with it's ability to produce boost strong by 3200 rpm. My car will hang with a friends '94 TSI awd running 15 psi with same mods except FMIC 2.5" short route piping and 550cc injectors. You be the judge, for me however, i'm also craving something externally gated

After reading ShapeGSX's report of 15 psi by 3000 rpm, I checked my turbo in 3rd gear: my MHI Evo16g (ported and clipped 10*) spools to 15 psi by 3100 rpm, and I have the stock bend at the downpipe, and stock flex section. After that it is 2.5" pressbent piping. So, even with a very restrictive exhaust (as exhausts go), spool is quite fast.

However, I do remember gawking at the 12.3 that guy ran on the Big T28 on pump gas--he is the ShapeGSX of the T28

MY Normal t28:
the higher I set the boost the lower it starts spooling.

at 10 psi (what it did hooked up the same as my formerly 16psi t25) it sucked and did not want to spoolup until late in the powerband... after adding a MBC it is now spooling much lower in the power band, around 2900 full boost... the one time I tested it sans wastegate it hit 15 in first at around 23-2500 (needles were swinging so fast it was hard to tell).

you might try and find a normal t28 for cheap and try it out, if you don't like it get the EVO3. If you do, well it's cheap and spins the same wheels as the FPBIG (except maybe their exhaust is smaller?) in a slightly larger housing. However it is a complete bolt on no mods or tweaks at all and no way without looking at the inlet to tell it is not a t25 at all. Especially with the OEM heatshields on it. I would prefer to run the larger t28's wastegate actuator, rather than reusing the t25s,but mine did not have it.

you can make any turbo look stock, just buy a turbo heat jacket and spray it heat resistant flat black paint. That will give you the sleeper look, less heat, and faster spooling times.

All three of those reasons sound pretty good to me.

umm yeah, what car you know has black painted turbos in a heat jacket stock? means it doesn't look stock and isn't a sleeper
