I personally think that the GT700 is the best of all worlds, almost no lag and neck snapping power!!

 

The logic thus far has been that these engines are good to about 700-750 HP with stock internals. Of course we're asuming good A/F ratios etc.. I made it a point to stop at about 600 crank HP to ensure reliability.

Would you elaborate please?

 

yes u should have took them... they were by far the best no lag ZC crazy *** turbos.... not as powerful as scotts 600rwhp k24/18gs up on top... but close...
they are not cheap though... and its a wait to get them.... but sometimes well worth it.
yes u can run straight gt30rs with out any work to them... all u need is custom headers to fit the flanges... and water cooling. Proto does it.
Joe, if Im not mistaken the gt700 uses gt28rs on them... and the gt800 uses gt30rs( i know for sure)... these have to be as laggy ... just my opinion though.... there is no way I can have a 640 rwhp car with the lag of a stock k16... this again is just my speculation... I need to drive a gt700+ car.
but my suggestion makes sense cause the rule of thumb is that more power = more lag
u have both so u can compare... can u explain further?
here is a pic of my engine with gt35rs .

 

Not sure exactly what the turbo hardware is, maybe one of the EVOMS gurus can chime in on this.

I can assure you that on a lag scale of 1 to 10 the with the NA CGT being a 1, the GT700 is a 2.5 and my GT2 is about a 6.

 

Also, from what I as told... Todd K....... that a car that has good air flow like headers... intakes, plenums.. etc.. .will dramatically help with spool up ...
its like having a gt2 with stock exhaust thats restrictive... compared to a non restrictive system... same thing...
So i think it would be difficult to make any sense out of a gt700 set up with all the air flow goodies and compare it to a gt2 with only k24s and exhaust....
What would make sense is to compare a gt700 to Scotts car... since he has similar power and all the air flow goodies....
any thoughts...

 

I can only speak about the cars that I have driven, but I know that I beat up on GSXR 1000s all of the time in the GT700, the car trapped at 136 in AZ with a DA of 3100ft on 19s. The GT2 version will be all that much stronger....


All on STOCK internals

 

I agreee

 

Ahh i see, makes sense! Never knew the different evo setups used the gt series turbo's, hmmm!!


Wow, i need to experience the GT700 badly!

 

the gt28rs are either on the gt640 package and the gt30rs are on both gt700 and 800... or gt28rs are on the the gt640 and gt700 and then the gt30r are on the gt800 package...
sorry that alot of bla bla bla....
either way.... I have driven cars with gt28rs and 30rs on a 2 liter motor so I know the spool up... we use them all the time on the evos...
Garrets are great turbos.

 

Ahh i see, yea im curious as to what the gt700 package uses, also wonder how the throttle response must be considering Joe gave it a 2.5 feel out of the GT2 6, i would love instant rev and throttle response like that, must be amazing in a turbo!

 

u cant compare the 2 with all due respect.... 2 totally different cars....
one has stock headers.. .the other huge 3 in 1 custom headers.... the intake and the plenum with the headers will give u a totally different car...
crazy TB response tahst for sure...... Scotts car is something to be compared to a gt700.

Oh no i know Mark, wasnt comparing anything more then the feel from the 2 with different setups!! Just said driving my turbo or a gt2 and then hopping into a gt700 car bust be an insane difference, especially since his review!

 

RenntechV12,
You trapped 136mph? Wow, 136mph is certainly very fast! So the GT700 seems comparable to Divexxtreme's performance, which makes sense, I would say about 600-620FWHP.

BTW, you need to change your sig, it still says 129mph..
Cheers

 

All I can add to this is AIRFLOW...or should I say HEADWORK!!! I can spool .7bat by 3100RPM's and full boost 1.7+bar by 3850RPM's, so take into consideration that the REDLINE is at 8000RPM's, you now have a 4150RPM powerband....so when you get out of first gear..you are under full boost for the other 5 gears...Headwork, headwork, headwork....Craig would agree with his experience of McKenzie's work.....

Joe,
I am willing to bet that if you left your combo how it is and gave the heads to McKenzie for an extreme head work job, you would gain over 100+hp..

 

So, does the headwork alone account for the quick spooling and 8000rpm redline? How bout some contact info for McKenzie.
