remote rurbo info needed i new to the world of turbos... im thinking about building a remote turbo setup for a ls2 6.0l from a trailblazer ss ( so its got the big plastik intake from it) in stock configuration/internals. It will be in my 55 chevy car. also planning to run a terminator x holley standalone.
im trying to sort out a turbine and the harware id need to make a 600 hp close. turbo. injectors pipe sizing and so.... looking for desecnt reliable stuff.
i already have a fitech 92mm throttle and a holley oil pan... may not change much.
should i run an intercooler? how much boost should i aim for?
ill be running the car as a daily driver and i want it to be the most reliable as possible.
any hints . tips. tech and knowledge is much appreciated .
thanks in advance guys
have a great day

What fuel 91/93 or e85? Ever hear of sloppymechanics? If not look him up, he is also denmah on here. A 7875 turbo would be my pick, you could go nonintercooled. Keep the hotside of the turbo kit small, 2" pipes. 2.5" on the intercooler pipes would be fine. If you have e85 use it.
If you want reliability, mount the turbo in the engine bay high enough to gravity drain the oil return. There is no good reason to remote mount a turbo in a 55 chevy. Remote mounts require an oil return pump which adds multiple potential failure points. Gravity never blows a fuse or burns out a pump, and less oil feed and return line length is less likely to be damaged and leak. The fabrication work needed to make a turbo kit will not be any easier for a remote mount than a proper front mount in that size engine bay. As for the other questions, that info is plastered all over this forum.

91 octane is the best we have around here. sometimes 94 .
and for piping u mean 2 inch exhaust from headers?

Full exhaust with a cutout would be a better method for maintaining sleeper status.
Stock manifolds, 2" primaries with a nice billet VS 7875 turbo T4 .96 AR would be fun on 91 pump gas and spool very fast.
I ran a cast wheel T7875 on pump 91 on my LS1 and made 700whp thru a T56 at 14lbs.
Stay around 10 lbs. to be really safe and 600whp should easily be attainable.
For fuel you could do dual AEM400's, -08AN feed and return, 1000cc injectors would keep you covered and give room for growth because no one stays at low boost for long lol.
2.5" or 3" piping for the intake, for an IC, CX Racing is decent for the cash, Treadstone is another.
I agree with ******, except for fuel pump. I had really bad luck with external 044 style pumps, many different brands including several aems. To me intank pumps are the way to go, the walbro 450 or 525 but that is my opinion. Alot of guys run Deka 80lb injectors and the decapped injectors do really well. Sloppymechanics on YouTube has many builds like you want all laid out, as well as plenty of threads on here. It's a simple recipe really, you can do it stupid cheap and it be good, or spend more money and it'll be better.

With regards to your reliability requirement, remember that twin turbos means 2 of almost every possible failure point.

He's gonna need electric pump(s) regardless, OP might want to consider a surge tank, best of both worlds.
I used dual 255's and Deka 80's in my previous car to get me to 700whp on pump fuel, no idea how close to tapped they were as I wasn't logging any of that data via EFI Live.
I'm running dual 450's in my current pump gas car, not because I need them but because they were on sale I wanted all the fuel lol.
The 450's did bring my IDC down about 10% with a -08AN feed from my dual 255's with a -06AN feed.
Using a BSFC of .6 (I think that's correct for gasoline?) and a 70% IDC at redline, I should be just shy of 900chp so if the OP ever wants more power, a 1000cc injector might not be a bad investment.
Not sure on the 55 chevys but they have retrofit tanks for alot of old cars. I've done 1 in a 66 chevelle and currently doing a 69 camaro. I think aeromotive has a kit to use intank pumps in about any tank thats pretty slick.
You're right though external would be the easiest, but if that was my only option I would pony up for a magnafuel 4303. I lost count on the number of 044 style pumps that left me stranded, and by the end they were installed and wired as perfect as they could be imo. I know some guys swear by them though, just sharing my experience
I have always run 2 external pumps in parallel, one pri, second with boost. I also wired them so if one failed, I could switch to the other and keep on running. In tank pumps have come a long way and immersed in fuel keeps them cooler, I know some guys will do a trap door in the trunk in case pump fails, so you don't have to drop the tank.
