Garrett GT28RS "Disco Potato" Direct Bolt On?

[S2peed]

Hello, I own a Skyline GTR-33 Vspec I wanted to know if the Garrett GT28RS "Disco Potato" is a direct bolt on of the stock turbos. Is there any modifications at all that need to be done or will it just swap right in with the stock manifold and other stock components. Thanks

I would thinkthey would have a far bit of lag!

they are rated at 380hp each.

yea I hate Lag, What about the Garrett GT28R Turbos will this turbos be a direct bolt on with no modifications.

GT-SS HKS turbz would be the way!

The GT28RS CHRA is very similar to the HKS GT2530 , the compressor wheel is a 60mm 62 trim instead of a 60mm 63 trim . The tip height is slightly greater making it a more efficient wheel with slightly better flow . In original form the GT28RS uses a .86ARR T2/25/28 flange exhaust housing and a .60ARR TO4B compressor cover . ATP Turbo are now doing them with the optional GT28 compressor cover (internally same as TO4B) which has the two bolt inlet and three bolt outlet compressor cover . There is a .64 exhaust housing you can use but dont know if its suitable for TT RB26 .

Well I am trying to hit the 450- 500 WHP with bolt on Turbos, downpipe and exhaust system, Intake system, intercooler kit, Camshafts, and a stand alone engine management.

I am looking for turbos with very minimal lag but able to push hard through the RPMs with out letting up in the high rpms.

I like the HKS turbos but there just too much money and for that money i can get the other components I mention up top. So I am looking at the garrett turbos. GT28R looks pretty good the GT28RS looks like is going to lag too much for my liking so I dont know.

Also I want to know if this Garrett Turbos will just Bolt right in to the Factory things. Thanks for your help

I would still go a set of HKS turbo's i don'r know why the americans don't like spending money on proven good parts.

we have GT-SS turbo's, we are currently producing around 480hp at the wheels.with hardly any lag.we make around 220AWKW at about 4000rpm, with a riv limit of 8500rpm.

Go the HKS path.
