What's up guys, so I am currently in the market to get a turbo for my build but have been a but iffy on which turbo to get. Here's my buid
- Golden Eagle Crank
- Eagle Rods
- CP Pistons 12-1 compression
- CNC block guard
- ARP heat studs, springs, and retainers
- B20 cams
- Victory X intake manifold
- ACL main bearing and rod
I'm gonna go with 2000cc ID injectors and a walboro 450 fuel pump on e85 when I do boost it. I'm looking to make about 500-600hp. I'm stuck between getting a 30r or a 35r and was wondering if anyone has run any of these turbos on here? If so what were your thoughts on it? Thanks in advance!

quite a difference between the turbos, 35r is much larger.....
30r wont make 600hp
depends on your goals and purpose

On my Gsr i have ran both . The 30r is far more street friendly as it has a usable torque band compared to the 35r . I was able to get 525whp out of the 30r close to maxing out though . On the strip the 35r really shines from 3rd gear on figure an additional 125-150whp more compared to the 30r . Most people here don't give a crap about drivability on the street they only want peak numbers .

Their are attractive options in between those sizes that do pretty damn well

I'm gonna be that guy and go slightly off topic.

There are much more options for 600 hp range that'll outperform the older gt35 design. But Garrett reliability and BB chra is the ****

And why are they so reliable? I think its the affects from being able to cool the turbo with actual coolant, instead of just oil.

I agree, our Holset tendencies coming through there ;-). A HX40 with the 14cm2 or 16 cm2 housing and proper split-pulse small runner manifold will be a great option too,

I suggest you change the cams though to help it breathe, the anemic B18 or B20 cams aren't going to support high rpm flow. There are a couple of threads on here discussing cam choices for a built LS turbo. Some guys are running like stage 2 NA cams (Crower) whilst others run LS specific turbo cams.

Have a look at some of the other threads for info.
