Upon the release of the new EVO-GT packages, I was compelled to determine how they all stacked up to each other. I was interested in not only peak HP & TQ numbers, but more so areas under the curve and how the bottom ½ of the RPM ranges compared. I was interested trying to determine from the data if different turbos were being used for the top end packages, or if the Garrett modified K16’s were being used across the range. I was also trying to determine what would be best for me if upgrading from my current Stage 4 GT/R (GT640).

The data has all been eye-balled from the dyno charts on the EVO website and are in no way intended to be factual. I believe the numbers are fairly close and are useful for comparative purposes, but then again they could be total crap.

Todd, please let me know if something is out to lunch here. I though it would be interesting to have a comparative discussion on the various EVO GT packages.

 

that gt-700 is badass. I would definately get that over the others.

 

I wonder if they were all on pump gas?

 

That's gotta be on 100 or at worst 93-94. No way it can be on SoCal 91 cr@ptane.

 

Yeah, the EVO GT-700 seems to be a clear winner. Drivable like stock with insane power - I´d hit it

 

What turbo does each kit use?
What is the boost level of each kit?
Which kits require rod replacement?

 

The GT-800 kit comes with an engine rebuild, including Carrilo rods. I would think however that forged rods would be a smart choice with anything more than the Stage 4.

 

Awesome chart Zippy it clearly looks like the GT700 is the best way to go

 

take GT700....and also do the internal upgrade for longevity issue...^^
hehe...this is what i'd do...

 

I have the GT700 installed on my car. It is totally AWSOME!!!

 

Great info!! I have the GT 750 and love it. The GT 700 looks to have the best daily useable power curve. I will be upgrading to the GT 800 this winter and adding some different gearing. Maybe those new gears will help?

 

btw Fred:
what kit do you have on ur car now???
the Stg4GT w/ new injector setup???
or you've upgraded them to GT700???

 

I've been thinking the same thing.

 

What does the GT 750 have for turbos? My guess is they are Garrett modified K24's, as opposed to the GT-640 & GT-700 use of Garrett Modified K-16's. Can you confirm this?

Yes I believe you are right. I asked Todd awhile ago and I am fairly sure he said they were modified K-24s.
