Dr-650 vs Dr-500

hey, I no ive been bugging alot of people asking this, but I gotta no in order to make the right choice, I want to get a nice turbo system that will give me alot of power throught the RPM band, also, something with very fast spool. I no that the dr-500 has faster spool than the stock turbo, but what about the dr-650? I've been checking alot of sites, but nothing tells me how fast it spools. I want to know, because i'm looking for something with alot of low end power, but still a little more power than the dr-500 will give me. thanks ahead of time, and once again, sorry to everyone who i asked this too 50 times.

well why just limit yourself to those there are other shops with the same prices some with more power some with less

like what?

cause DR turbos are the shiznit, unless you wanna do something like just buy regular 15g turbos from just any shop. There's the ever popular WRX turbo upgrade that i'm still in the middle of, you have to customize it to work, it spools as fast as a 9b turbo yet gives the top end of a 15g. Its a td04hl 13t, which will have slightly more top end than the dr500s.

Basically what people say, dr500s are better street turbos, and dr650rs are better track turbos.

thanks... by the way... how much PSI can the Dr-500 take?

the dr500's are the turbos like 13g's so the max boost should be about the same.the dr650's are considered to be similar so there max boost is the same only thing different is the clipping and porting.i would say the 650's are the better turbo but also gtpro has a better turbo if u want to drag.but the dr650's would be a very good choice if ur street/track turbo the dr500's are strictly a street turbo.as if u look at like the dr1000's those are just for drag due to lag. so the dr500's have minimal lag,dr650's have little lag and the dr1000's have to much for daily driving.
