5x.18 injectors what size turbo.
 

I just found out my injectors are 5x.18 what single turbo should I run on this truck to lower my egts and my smoke?

If you wanna run those injectors full out you'd need a s400 chassis single basically or twins. You could get a 63/68 and have lots left over and spool fast, a 64/71, same thing. A 66/71 or 73 and would still have fuel left over. 66's apparently aren't very fast spooling. Then you could go s464-s471 maybe as a single but be pretty slow to spool aswell unless you had like a spool valve. 5x18s are like twin injectors

Yeah well they are already in my truck. It's what I got it with them already I can go WOT for like 5 seconds before it jumps past 1200.
Im a marine and I don't really have to money for twins I'm actually think I may just save up for a spool valve.

Fair enough man. I'm in the same situation, don't want twins but want biggish usable power. Going s467.7 and a spool valve and 5x16 sac's. I'll report how it does. And hopefully it can help your decision if you haven't bought your set up yet

I did find a used BW s472 96mm turbine 1.32 A/R housing for $400 does anyone know how this would do?

Fairly slow, you def will want a spool valve. Hopefully you have a cam or something and probably high timing. For street use it would be kinda hard to drive smokeless, especially with an auto. You may want a smaller ar housing. If you do go with it. Gonna be tons of air though. And should fly up top

Well if I get this turbo I can get a spool valve for the cost I can justify it. Drive smokeless? I can't do that now. I have black out a interstate before merging. What size housing should I hunt for?

Something closer to a 1.0 would help spool. Not sure what's avalible for 72's

Would this work?

Ya if you went .90 with no valve or like 1.0 with a spool. The 1.0 is probably the better choice with a spool valve.
