so I am new, and I was curious what y'alls opinion was.. for a 12v twin set up, would you prefer s475-hx45 or your own opinion of your choice? I will be pulling sled and I will have a 215 with 5x25s possibly.

 

welcome to the site
go to our cummins section and ask people will have great insight
i have a compound set up and your injectors are way to large for the set up you are talking about

 

Im wantin to use 5x25s, but I also want twins. Single turbo I was thinking gt42 but like I said I want compound turbos. What did youhave in mind..turbo wise for those injectors

My boyfriend has a 98.5 12v with 215, gt42, 5x25s, no plate, SB dd, and extreme custom cut pistons, he loves his injectors but i dont want the same exact set up.. thats the reason for my twins im hoping. and would 5x16s or 5x14s work well with my set up? Really hoping for a set up for 5x25s, HELP PLEASE!!

 

are you going to pull in the open class
with that small of a primary i wouldnt recommend anything over a 5x16
if you go with a gt4202 with a 1.1 turbine housing and mods to help it spool a set of 5x20s would be ok
but as for compounds the turbos will have to be fairly large to run that large of an injector

 

Yes and ill be takin chances at 2.5 and ws do you have any suggestions turbo wise for larger injectors

 

for compounds you could run a 63/68 .83 over a 83mm or bigger to run over a 5x18s or nothing larger than a 5x22
what mods are you going to do to the engine to aide in your power quest

 

That part im still unsure..

Why are there so many running 5x14s with 62/68 ? Is the 62/68 really reliable

 

It is a really good well rounded turbo

 

 

the more fuel the better really. so if i use big injectors and a nice sized turbo/twins i need all the hp i can get, and i appreciate all the opinions and suggestions but i dont live by the book
