Stage IV (final stage for my SS-Four), Update: July 24th. Options

[malpaso]

One year after "Great SS-Four rebuild" (http://www.6gc.net/forums/index.php?showtopic=78088) was finished I left my car in my mechanic's hands again to start fourth and final stage of my car's build. Goal has two parts:

a) check everything on the car after 12 months
b) just slightly push car higher in terms of power (+20%)

When I have my car back I plan just add some "unnecessary weight" and DONE! All finished.

It has begun!
What I can share now with is just the most important - new parts ready to install

Bigger injectors...



Bigger - custom build/modified - turbine (enlarged housing, enlarged wastegate, polishing, etc...)







stay tuned...

Wont that large of a turbo = massive lag?

It's a GT28R based turbo, T28 is alot smaller than CT26/CT20b turbos. The compressor on this is a 2876 (or equiv) which is pretty much the same compressor on the larger GT30R (3076). this means a power output AND spoolup somewhere in the middle. the GT28R is known to spool well before 3000rpm and the GT30R is known to spool before 4000.

So yes, the boost threshhold under 4000rpm will be lower than what you're used to with a GT28R and even the CT20b, _BUT_, the ball bearng centre cartridge means that the turbo will boost to its full boost threshhold as soon as your foot goes down, theres no response lag and theres no spoolup delay like the time it can take a journal bearing turbo to change from 40,000rpm to 140,000rpm for example is responsible for probably about 500 engine rpm of lag

Thanks mate. I would not described that any better

Martin, you keep on surprising with good things - I've never seen a turbo cover like that. Pretty cool. Those look like...35 or 40mm spacers?

It is heat sink cover made of titanium fiber and has plenty advantages . Those spacers are not that big as it seems. For rear it is about design and front it is more about function (I need some space there ).
