T28 Turbo Question

[soultz]

Hey guys,

i got 2 turbos with a t28 exhaust end, will a skyline, silvia or 180sx dump pipe fit them? same flange??

cheers

Won't fit on a t3 flange

They should a sr20 dump should fit if they are 5 bolt or a skyline dump should if they are 6 bolt. If you want a t3 flange a rb turbo rear housing will fit depending on brand of turbo at they are t28

huh?? so a sr20 dump pipe will fit??

[Bsa]

How many bolt holes are in the housing where the dump connects

[Lukez32]

I thought you meant manifold flange

[soultz]

the back of the turbo has 5 bolt holes...its a t28 turbo...what dump pipes can i use, off what car?

[Bsa]

Sr20 is my bet so silvia. Skyline t28 turbos are 6 bolt

[soultz]

thanks guys!! now i know what to buy

[Bsa]

What are they going on

[soultz]

ive got a vt commodore, ive spent about 10,000 on the engine, its a 4.2lt stroked twin turbo, ive got the turbos, just no dump pipes

I'm guessing you want low to mid range torque then why not run a big single

Sorry but GT-R rear housings are 5 bolt too. RB20/25 uses a 6-bolt rear housing which AFAIK nothing else uses. I think the two 5 bolt housings housings are different:

SR20 - http://zage.en.alibaba.com/viewimg/picture.html?picture=http://i00.i.aliimg.com/photo/v0/243832912/Nissan_Silvia_S13_S14_S15_SR20DET_Turbo.jpg

RB26 - http://zage.en.alibaba.com/viewimg/picture.html?picture=http://i00.i.aliimg.com/photo/v0/242274706/NISSAN_SKYLINE_R32_R33_RB26DET_Turbo_Turbine.jpg

so, find out which one you have? T28 from S13/14/15 will bolt to SR dump... from R32/R33/R34 will bolt to RB26.

Sorry but GT-R rear housings are 5 bolt too so GT-R dumps should bolt on. RB20/25 uses a 6-bolt rear housing which AFAIK nothing else uses. Anyway, the dump (rb26, Sr20, CA18) will bolt onto the turbo, just be aware the reason skyline owners don't use SR20 dumps is that they don't remotely match up with the rest of the stock exhaust setup (from memory) and they aren't particularly good.

hmm ill keep that in mind, ill look for gt-r ones then maybe...thanks mate!

Yes but 26 turbos are t25 not t28 and also have there own funky thing going on with flanges but you are right the dumps will fit a stand corrected on skyline dumps will fit only rb20/25 dumps are 6 bolt and won't fit

i was going to run a big single, but this hasn't been done before, ive spent a lot of time with the car fabricating things, i wanted it to be different, i should get more then enough power from this setup...
