t28 BB
I searched but really did'nt get the info i needed,about the t28bb it was said that with this turbo from the TSI kit upgrade you cannot run a/c is this true? Any members find a way around the problem was it the downpipe hit the a/c lines or is it that the ic pipes have to be customized somewhat from the kit. Any feedback would be appreciated!!!

Nothing needs to be modified or removed with TSI kit.
abs, a/c, p/s, washed bottle - all stays.
t28 is not much different from t25
They both have same exhaust housing, but t28 has bigger intake housing, I think it t3 intake.
Thats about it.

There is no T28 ball bearing turbo. Garrett makes a t28 turbo but it isn't ball bearing. The ball bearing turbo Garrett does make is a GT28 r or rs. These are decent turbos but pretty pricy, imo.
As far as the specs on the t28, it's a good sized turbo but due to the large size of the turbine housing, not to mention the trim of the turbine and compressor wheels, it won't spool up very quickly, it's a little out of the efficiency range for a 1.7.

Rep Power: 327 i beg to differ on the spool up time of a GT28R if thats what your refering to. Im in boost at as low as 2100rpm, and 7psi at as low as 2500rpm. I sometimes wish it was a larger turbo so i wasnt in boost as much

Now, the sylvias use a t28 bb, but I don't believe its found anywhere else and I'm not sure of the specs on that turbo, either. There are limitless combos you can find with turbos but ebay isn't the place I'd look for one.

Rep Power: 0 I see what you are saying. If you get a chance check out ebay motors and type in D17 TURBO and tell me what you think about that TSI kit for sale does it look complete. I don't wanna reach really high numbers just get resonable amount of power out of my car. I also wanna keep it a daily driver of course with that turbo you think it will be okay for traffic in Killeen? I got your # man my wife took my phone by accident so i'll have to call you when she comes back from San Antonio. ----Peace
hmm learning alot about the t28 here. doesnt garrett make the t25 bb, or would that be a in-house job like you were saying, rebuilding it. because ive got the tsi kit and id like to upgrade just a little to a bb turbo....im pretty sure it has the bottom of the line choice for turbos for this kit.
sorry to jack the thread, just hoping this will bring outmore info on the t28's and t25's

Rep Power: 280 Just to add few things...
Both t25 and t28 are good turbos for a basic street kit.
If t3/4 is quick spool, then what is t25 then?? Extra super quick! Fool boos way before 3000rpm. Sometimes its a bit tiring.
As far as fitting tsi kit with t28 instead of t25, Turbo Specialties (tsi) kit does not require any modifications (as per tsi), exturbo6 had problem, but it was not due to tsi, but something doe to clutch cylinder.
t28 will be even tighter fit to t25. My t25 intake housing (should've I say compressor side??) is very close to an engine block.
My t25 dyno has full power at about 6000 rpms and t28 will produce power a little further into rpms...
I get very good low end power, car feels as a blast when revved to mid rpms, not as much in 3rd, but in 4th gear I see engine not willing to go to the readline after 6000 rpms (luck of efficiency), but switching to 5th will make car jump into rather brisk acceleration...

i made 650 at the wheels on an SRT4 with a GT35r with the .63 housing
i just think a gt40 would be a little large for a daily driven 2.4L honda
and no, im not taunting you or anything. its just that you said gt40, and that turbo is the size of my engine

Rep Power: 0 Is there different trimmings for T25 n T28?
S15 has the T28 as stock turbine... the A/R is 0.8. Can we still use this turbine on ours?? Seems like the HKS site has T25 n T28 in A/R of 0.64 and 0.8 respectively..
Whats the A/R of the T28 from TSI?? Thanks for the info...

Mine was builing max HP @6000 rpm and flat from there at 7psi on a conservative tune. Im thinking it could be do to restrictive DC sport TCS exhaust possibly, or the 2.25" Downpipe

Sounds like you dont know to much about t-series turbos. Silvias use a GT28 as a stock turbo, FYI its a DUAL ball bearing turbo, water cooled turbo.

T-series turbos are the TSO4, T61, T64, T66, T70, T72 and T76 turbos. Not T28 turbos.

. Im not for sure on the downpipe therory. I mean if you click my signature and look at its pictures its prolly as free flowing as ANY 2.25" downpipe ever made, but im sure it would free up some HP if i went larger Registered!!

Why whouldnt t25/28 be included, it does have "t" .....??
Does it mean t3 and t4 are not "t" series turbos as well?
