I own a LS integra. I just bought my turbo kit, and as of right now, I plan on only boosting about 7-8psi. Besides turbo timer, exhaust, and intake manifold(I already have these three things), what do I need to run safely? I'm getting a Hondata Stage 2 with boost for sure, but i need to know what's the most important at this point?

 

If you're going to run the Hondata, then you might as well get some larger injectors and an intank pump to go with it. You can get some DSM 450s, but I don't think you can idle them without the Hondata or a piggy-back fuel controller.

 

There's a group buy right now for RC injectors. Which one's should I get? The 310's or 440's? The 440's are $3 more.

 

440s should be good if you're going to run Hondata.
