Some detailes and prices would be nice

 

1000HP is easy, just not on the pocketbook. Jags, can you say full build, cams, headwork, blueprinted, balanced, rods, and the list goes on.

 

Jags - the GT700 is a very comprehensive package. It combines increased airflow and fuel flow. I feel it could be a very balanced end destination for many people.

 

Thanks, bur can you be alittle more specific as to driving experience. Also did you go from a gt640 to 700? If so, what were the main differences between the kits

much appreciated

Jags

 

Driving experience - not a ton of difference from the 640. The upgraded fuel rails, injectors and pump seemed to make a lot of sense to me. I was always a little concerned the stock fuel system was over-burdened by the significant air flow increase produced by the Garett modified KKKs. As Stephen mentioned, the increased capacity of the upgraded fuel systems opend the door for future power increases. This could mean GT800 turbos, increased airflow via head work, cams and/or intercoolers or some combination of the above.

 

Soon eventually.

 

60 hp difference... I dont think you will feel much if anything....

I can understand stage II to StageIV...not 640-700....

If you want a difference... go 800HP...

 

Thanks gang. What does the Larger TB and modified ypipe do if anything?

Also - other than different software, enigine rebuild, and turbos, is there anything else added to the gt750 and 800 from the gt700?

 

depending on what turbos u start out with ... but u can keep the same ones... like if u have the gt30r garrets then u can us ethem with the gt800.. tahst what sharky has and even Craig... quicker spool...

 

Markski - Are the GT640/700 turbos = to GT30R Garrets?

 

craig,
I'm so glad you are on this forum. Your pure enthusiasm for the pursuit of horsepower and speed is a true inspiration to me. Keep up the good work my friend!

no... the gt640 doest use the same turbos....

ist only when u go with the gt700/750 is when u have that option....

the gt640 uses a 5 bar fuel pressure regulator..... the gt700 and up uses the hole new fule system....so its set up for bugger turbos..... these are stuffed into the kkk housing... u have a gt700 dont u ?

 

Yes I do - but it's my understanding that the turbos on the 640 and 700 are the same. 750 & 800 are a bigger set. Hence my question regarding your previous statement - "like if u have the gt30r garrets then u can us ethem with the gt800.. tahst what sharky has and even Craig... quicker spool..." I assumed you were implying the 640/700 garret mod turbos were gt30r's and you could optionally use these as opposed to moving up to the bigger turbos that are a part of the 750/800 kit?????

 

hmmmm.. we need stephen.... if I recall correctly.. he told me a while back taht the gt700/750 is the same set up turbo wise.... and if u eve moved up to do ur internals... u wouldnt have to change them out..... just crank up the boost.... tahts where the gt800 comes in....
it doesnt even make sense cause the gt640 uses a 5 bar FPR.... good for about 600 or HP.... anything after that u have to go with a fuel system...
I just personally dont see how they would be sticking gt30s on a gt640.
I think that comes with a gt25r garrett inside a kkk.
