BIg T28 vs big 16g

[CBgst]

I'm looking to buy a turbo but can't decide whether to go with a big t-28
or a 16g. They are about the same price (with the install kit for 16g) but wich one will make more power. Also is it possible to dip in to 12's on these turbo's or should I go bigger cuz that's my goal.

 

[CBgst]

One other thing also my budget is about 3200 for turbo and supporting mods.

I have not seen any 12's FWD cars on a Big 28 yet.

With either of these turbos, FROM WHAT I HAVE READ.....low 13's are the ticket. You need a bigger turbo with more lag and a higher top end charge. Go with a 20g, and 3" exhaust, 660cc injectors or 720's, MBC, UICP and LICP, 1gen Throttle body, and intake if you can get it. With those injectors you'll need fuel control, go with a S-AFC, and also get a EGT gauge a boost gauge and do some tuning. Also a upgraded clutch such as a ACT 2600. Should be a high 12 right off the bat. then tune tune tune to LOW 12's.

at dsmotorsport you can get a t3t4 with manifold, wastegate, and o2 housing for 1775. the smallest one the make is comparable to the 20g, or so they say.

I agree with everyone else above.. the words 12s, FWD, and Big28 or 16G dont really mix.. I mean it can be done but its ALOT harder then youd think.. A bigger turbo would suit your goal for 12s like a 20G or someting of that nature and dont skimp out on supporting mods.. they are just as if not more important the he turbo itself

 

[CBgst]

So far I already have an evo o2 housing, full custom 3in exhaust, Buschur uicp and 1st gen bov, Turbo xs mbc, areo speed filter w/ adapter, ported exhaust mani and turbo, solid motor mounts( didn't buy inserts filled mine w/ 3m window weld), Auto Meter boost gauge,and free mods. I was planning on a turbo, fmic, feul pump, clutch, egt guage,and an S-AFC. Injectors will be coming soon after but I think I'm already cutting it close to my budget with this stuff. I'll just keep the boost down until I get everything.

Alright I got a 95 talon tsi awd, going to upgrade my turbo along w/ supporting mods. big 28 or big 16 g I know the big 28 bolts up to my car, I want to know performance wise, I hear the big 28 is the best all round turbo and then I hear the big 16g is the best one.
What I want to know is
which one spools quicker
peak boost capabilities
experience w/ either
looking for a fun street car that can run low 12's possibly high 11,( I will be doing engine mods to it also in the future to reach this and know I will be have to riding on the edge of tuning but which one is better??

 

[DMS-WhiteGSX]

I don't have a lot of experience with the big28, but I do have a lot of experience with the Big 16.

My big16 is spooling around 3800ish, due to my lack of tuning and pulls hard well past redline (I shift at 7200rpm)

I have been running my B16G at 20psi, and have had it up as high as 23psi at the track, I believe that the big28 is about the same in this aspect, dunno for sure, if I'm wrong someone correct me.

My car is a 12 second car, after it is all tuned, I'm sure. But I have all the supporting mods for the turbo, which you will too.. (injectors, fmic, etc)

I don't know what turbo is better, because I don't have experience with the 28, but the 16G is a nice turbo, and I reccomend it if you are loooking for a new one.

Well, I don't have either one, but from what I've read, the Big28 will spool quicker. FP says it will reach full boost at just over 3000 RPM.

 

[mike9146]

"FP says it will reach full boost at just over 3000 RPM."

That doesn't tell you much. My Big 16 will do the same, in 5th gear, but
as you go down in gears, the time that it takes for the engine speed to climb gets to be faster than the turbo can spool. FWIW, my Big 16 hits "Full" boost somewhere between 3500-4000 RPM in 2nd gear.

[RetardedAWD]

My ported big 16 hits full boost at about 3300 in 1st gear.

 

[95talontsi]

guess no one has a big 28 huh

 

[CL MaNTis GST]

ask larry...

 

[RocketDSM]

I would say go with a Big16 if youare not very knowledgable of the intricacies of turbos. This is only because A LOT of people know how to work with a 16G (big or small) and know how it flows etc. Not many know the tweaks of a T28 which will reduce your pool of expirence to draw on. If you just want to bolt and run, get 16G. If you want to play around tweak and expirement, get a T28. MY .02.

 

[RocketDSM]

Keep the boost down he says....HA. Has anyone here been able to stay off the boost once you know it's there? I'm not saying you can't, but it is a rarity. I'm one of the worst, I have very few supporting mods and run rather high boost for the gas I'm stuck with. IMHO, I think you can do 12s with the setup you have/want (16G/T28) but you main problem I can see is the FWD. Traction will kill you in the first seconds. If you can get that setup tuned to max, AND HOLD IT DOWN TO THE ROAD, I think you'll pull a 12. But I can't see you holding traction well enough.

 

[95talontsi]

hmm sounds intresting, really is between garret turbo and a mistu, forced performance makes the big T28 the same guys that made the green and red series that are awsome turbo's. Your right rocket because the turbo guru's would know exactly how to tweak a big 16g, tough decision huh

 

[RetardedAWD]

eheh.. its tough not to show off once in a while or just build boost to scare someone with the BOV..

 

[NJGSX96]

95Talontsi... where in NJ are you?

Anyway, I have a T28, original Turbonetics T28/S60... before ANYONE liked the T28 is when I got it. I personally like it. It is an excellent street turbo and not too shabby at the track either. it doesn't have the pull of a 16G up top, but will hit full boost at around 2800rpms in 2nd and 3rd and does pull well to redline. Tuned pretty well I have been able to run 13.3@103 on it.

The FP BigT28 is supposed to be an improvement on this turbo design, and if it is, it would compete well against the small 16G. The average time on AWD cars seems to be 12.6-12.8@105-107. That is right in line with average, semi tuned 16G cars, that I know. Yes, I know Loren ran an 11.9@119, but who has duplicated that time since? No one I know of.

i think the question you should be asking is should I get the Big T28 or the small 16G. If you want that extra umph, then go for the Big 16G. Otherwise, I think it is a toss up between the 16G and Big T28. Within the next couple months I'll be swapping out the small 16G on my 1G for a 20G and then that 16G will replace the aged T28 on the 2G. When I do that I'll have a decent comparison.

 

[L2RTSiAWD]

Merging both big-28 vs big 16g threads.

 

[97GSTAT]

I've had experiences with both those turboes, granted not in my car. And from what I've seen they almost the same performance wise. The Big28 will spoll faster, but the Big16G will pull harder in the top. I honestly liked both turboes, but I choose something different, S16G. And so far I happy with my decession. And I'm shooting for 12's with a FWD A/T, so anything is possible.

 

[SPEEDY]

You guy's have to remember something here. It is going to take alot to get a fwd dsm into the 12's even with a 20g. There are alot of guys with 20g's that can't even bust 12's, because of tuning and traction problems. There isn't a whole helluva lot of people with the Big28 either. I mean it's only been out for like 8 or 9 months now. Larry ran a 109 trap untuned, and without any cams, which I think is already good enough for 12's. Brian at FP ran a 13.0 flat at 115 with a 1g tb, 1g intake manifold, and HKS 264/264 cams, now the last time I checked that 115 trap is in zo6 territory, so that ought to tell you something, that even with 115 traps your still going to play hell getting into the 12's. Brian claims with that 115 trap, he was spinning all the way through the 1/8 mile marker, so with a LSD, and some drag radials, and a good suspension set up it could and can be done IMHO. I'm more of a street racer guy so most of my races are from a roll, because of the area that I live in. I know that when I finish my set up I will definately be a mid to high 12 sec car from a "ROLL". That's all I care about! If I were a hardcore drag strip racer I would have bought an awd to begin with. But I'm NOT!!!

Thats just the thing.. I'm sure that car had a lot more done to it than just the run of the mill street tuned car. Either turbo from what I have seen are really good turbos, but its all in what you want i guess.

Speaking of Loren Check it out.

 

[DMS-WhiteGSX]

Ouch, now that sucks.
