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

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?

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.
