Coverting twins to a GT28RS?

[Archlab]

I have recently ordered a RB26DETT and was having fitment issues with custom making a twin downpipe (I dont wanna custom make one that is pretty much the problem) and i got a GT28RS .60 turbo layin' around. so my question is...is the GT28RS .60 a big enough turbo to convert to single turbo on a RB26DETT, would I be losing power? Would it just be stupid, pretty much what I am asking is what kind of turbo do I have on my hands here?
I do not know how to tell if one turbo is bigger than the next?
:thinking:

:thinking:Personally i'd think a GT35R would be better suited but not positive on a completely stock engine, i'll look for the graphs...

Here's a few examples on one, still looking for both the GT35r and Garrett T04Z...

hrmm... RB26 with single T45S seems to be making 580-600 around 1.5bar

Nah, a T28 is WAY to small for an engine like that. But what might help your question get answered better is, what are your power goals? The twins that are on there are bb turbos and are quite good and it'll take a good sized single to make up for loosing the twins. I even thing a GT35 would be too small. GT40 or bigger.

Ah, here's one...

"Dynod my car yesterday, we ran in to a problem with the fuel system, I need to mount the second 044 motorsport pump. We could not go past 1.5bar and 7.000rpm because the fuel pressure started to drop

But it made 625hk/655Nm at 1.5bar (564HK/590Nm @ wheels) max tourqe was at 6500rpm but I think that will be at lower RPM when I can run 1.7bar"

WAY TOO SMALL

Id do Twin 25Rs like Ivansnow and make 450whp

Ill buy that 2860 off you thought for my SR :)

[Archlab]

So I need me a GT40 then, what A/R etc. should I be looking for?

and why are turbos so hard to find on the internet, cant find a damn place to find one much less descent prices wow?

[Vteckidd]

i can get Garretts.

if your going for SINGLE, MINIMUM id run is a 35R, good for 500-600whp, but a nice powerband since you have a big motor.

PT67 is nice too

thumper ftw

I just want to say RB26DETT engines comes with 2 t28 turbos, so putting a better t28 turbo to replace is something silly...

You just need to know swapping engine needs a lot of custom parts.

ill take that turbo off your hands...pmed

a t28 and a gt28 is not the same thing

THOSE ARE ABOUT THE SIZE OF A T3/T4 TURBO
