To all you power junkies:

I have a stage 2 setup on my 01 996tt. I want to go to stage 3 or 4.

I have been told by EVO and others that use GIAC software that the same software is used in stage 3 and 4. The only difference in the packages is the headers.

That being the case, what turbos should I go with? GT2 K24's or Kevins stage II hybrids?

With either one, what HP and TQ am I looking to gain.

I have also been told that with the stage 3/4 software (because they are the same) the K24's will spool like K16's?

Others have told me that the K24's will not spool like K16's even with the stage 3/4 software

Sorry with all the questions, but I just want to make the right decision the first time.

Even with the stage 3/4 GIAC program. The K24 will not spool up as fast as the K16. I can comfrim it cuz I done couple runs with my friend's Turbo S with GIAC program. I can jump 1 car lenght at start. But at the high end (200km/h +), stage 3 will eat our stage 2.

So peak HP is not everything, depends on how you drive your TT. City drive, I will stay at stage 2. If you do lots of high end run, stage 3 or 4 is for you!

 

Go with the K24's as the programing is specifically designed for K24's

 

Does anyone have the part number for the gt2 k24 turbo's

Ray - what stage program did your friend have? Did he have an exhaust, intake, and DV's too? Also - this may be a stupid question, but the turbo S has the K24's right?

Thanks

I've also been thinking about putting GIAC Stage 3 or 4 on my car, but EVO saying Stage 3 and 4 use the same software has me a little perplexed.

If Stage 3 has ~550hp and Stage 4 has ~600hp, then the headers alone account for a 50hp difference? And if its the same software, why does the Stage 4 program cost $400 more than Stage 3 program (http://www.evoms.com/p996tt%20computer.htm)?

 

Good question - both Nate at Evoms and Steven at AI told me it is the same software.

Jags

 

I believe it is the same software. The 600 hp is with the headers on high octane fuel. The extra $400 is for the 100+ octane program? Here are the part #'s of the K24 Turbos courtesy of Loren @ Renntech.org.

996 123 983 71 Left turbocharger -- Retail $3022.65
(as of Oct 2005)

996 123 984 71 Right turbocharger -- Retail $3022.65
(as of Oct 2005)

 

Thanks - but I need the Bo Werner numbers

My friend have the stage 3 program with no exhaust and header upgrade. The TTs have the same K24 in X50 and GT2.

 

From what I understand, the exhaust alone makes a huge difference in the spool up time because the stock exhaust is very restrictve.

Jags

 

I believe there is a stage 3/4 program for the GT1 (K16/24) hybrids. The GT1 turbos should have less lag than K24's with slightly(?) less high rpm horsepower.

 

Well...

I did stage by stage from 1 to 4 and the Stage 4 software is different. Maybe today is another story.

However I did run stage 3 and honestly just stay with Stage 2, only go 3 if you plan soon to go 4 beacuse that is a big smile in you face

4 is the way to go...just adictive.

 

You think 4 is great try 5!



It never ends!

 

What is the difference from stag 4 to stage 5? 604 to 700 stage.
( both being on a pump 91 gas program )
